Hawks are Back
Nesting again on Dogwood Ranch, the red-shouldered hawk pair built its nest high in a tree by the dogwoods. True to usual form, they piled sticks in the crotch of two large limbs about 60’ from the ground. Also as usual, they make it very difficult for us to see the nest, much less into it, because it is blocked by limbs and leaves of other trees. Using the binoculars or the telescope, we are able to see what we think are adult tail feathers and every now and then, the fuzz of a chick’s head. Two weekends in a row, while drinking our morning coffee on the porch we heard what sounded like a hawk call from the woods across the creek. But this call did not sound good, not like the strong fully-in-command calls we normally hear from the pair. We grew concerned that maybe one of the hawks was not well, desperately calling its mate. Whatever was making the sickly call from the woods, we soon were relieved to hear that it was not one of the mating pair. The sick call seemed to get the nesting pair’s attention, and they began calling to each other in load, strong healthy calls. One flew to the top of a dead limb on a tree we call the “hawk perch” because they seem to land there often. The bird landed, perched and flew off several times, with loud calls. After about five minutes, the weak call from the woods stopped and the mating pair quieted down. Strange. Could it be an intruder trying to invade their terrirory? Is it last year’s junior hawk (who we never actually saw last year) still hanging around mom and dad a year later? We don’t know but we are certainly glad the pair that we have enjoyed watching and listening to for so long seem healthy and are attending a new chick this year. We will keep an eye on the nest and hope to see junior take flight!

Lone Duck
Lone Duck arrived at Dogwood’s pond sometime in December along with fellow wood ducks (Aix sponsa). The wood ducks use Dogwood’s pond as a weigh point along their migration path and usually only stay 4 to 6 weeks. Early this year, when his buddies flew off to continue their migration, Lone Duck stayed behind on Dogwood Pond. He was the lone duck on the pond, gently swimming to and fro keeping at least ¾ of the pond between him and us. I guess he decided hanging out at Dogwood was the good life, so he decided to stay as while. He seems to like swimming close to the bubbles from the diffuser in the pond, maybe the bubbles tickle his tail feathers.
Lone Duck is a male. He sports crested head of iridescent green and purple with a white stripe from the eye to the end of the crest. The bill is brightly patterned black, white and red. Since female wood ducks have a gray-brown head and neck with a brownish, green, glossed crest we are confident Lone Duck is a male.
First notice of the wood ducks’ arrival at Dogwood occurs pretty much the same way each year. We pull up to the gate at Dogwood, rattle the chain lock and we are startled by a whoosh! The whoosh is the 10-20 wood ducks suddenly flying from the water up to the tree branches of the nearby woods.
After his buddies left this year, at first we thought that Lone Duck might be sick or unable to fly so he stayed behind. We expected to see him wither away left all on his own. Fortunately, he seemed to be healthy and was maybe just a loner. According to Wood Duck Society, some wood ducks don’t migrate with the rest, are loners and very picky about choosing a mate, as they should be.
Yesterday, Lone Duck was gone. Hopefully, he found a girlfriend who shook her tail at him enough that she lured him north. There are no ducks on the pond now.

Cedar Bridge – Part 3
Although we initially had some help with cutting down the large trees and planning some of the trunks, for the most part, it was the work of just the two of us. We did the measuring, marking, re-measuring, re-marking, cutting, sawing, clamping, gluing, pushing, slamming, dragging, fitting, lifting, hammering, drilling, cussing, swearing and cursing ourselves.
We hope in the spring when dogwood trees around the bridge are in bloom we will have an official unveiling of the bridge and some nice photo-ops.
I have concluded that every couple should build a bridge together: literally and figuratively. If they are still speaking to each other when the project is done, it’s a good strong relationship. We are still on speaking terms.
That is not just water under the bridge!

Cedar Bridge – Part 2
Cutting cedar and plywood to length and width per the final design was the task for the Fall of 2010. Using a portable generator to provide juice for the power tools, we constructed the trusses in the dogwood area holding the pieces together with “liquid nails” (glue), plywood plates and galvanized bolts, washers and nuts. Finding the necessary quantity of hardware required multiple trips to various hardware stores in Brenham: Home Depot, Lowes and McCoys. Checking out during an emergency run to Brenham’s Home Depot for more 6” long galvanized bolts, the young gal running the register was sure the $3 per bolt price was wrong. After verifying the price was correct she said, “Honey, those are some expensive screws-they better hold your stuff together good!” Of course they were bolts, not screws, but I let her slide on that as I certainly shared her sentiment on the price. However, I’m not so sure my “stuff” is held together "good" with or without expensive bolts.
The following weekend, braces were placed between the beams at approximate 3 foot intervals. We cut the cedar planks into six foot lengths and carried those six at a time on the Ranger to the site and placed them across the beams and trusses. It was starting to look like a bridge so we were spurred on to finish the planking. When all the planks were placed, we trimmed them to fit and screwed them down. We were Goldilocks on the planks as we had not one too few, not one too many, but just the right number for the job. Was it pure luck or precision planning? Either way, we have a functional cedar bridge.
Next time we will install the top pieces of the trusses. Also ramps on the banks are needed so that a vehicle can drive onto the bridge.

| Piers and center cross beams |
After building both trusses, we partially dismantled them for transport to the bridge location. Before beginning construction, we installed two concrete piers in the creek bed (the creek is seasonal so it only contains water after a heavy rain, which we have not seen much of lately). We dug two holes in the creek bed about two feet deep and parallel to the bank. We then put a 12” diameter cardboard tube in each hole so that about a foot stuck out above the hole. We filled the tubes with cement mix, added water and mixed well to make slurry. Rebar was inserted, metal brackets placed on the top of the wet cement and cement hardened. Using the metal brackets, on each cement pier we installed wooden posts and two large cross beams across the posts. The trusses and the other beams traversing the creek will rest on the cross beams for support in the center of the bridge and on the banks.

| Beams and bottom trusses spanning the creek |
Next, we constructed center beams to span the creek and set them in place from bank to bank. We also transported the bottom parts of the two trusses, in two parts each, to the bridge location. Each piece of the truss, was transported one at a time with the ATV and a little trailer. The trusses still dragged on the ground behind the trailer. We then installed the bottom portions of both trusses and attached them together with those expensive bolts, nuts and washers.

The Cedar Bridge- Part 1
Enjoying use of the rainbow bridge over the creek in the front of the properly since December 2003 (see Speaking from the Ranch post of October 24, 2010); the cedar bridge will complete the loop over the creek in the back of the property. The genesis of the cedar bridge was twofold: 1) we needed a bridge over the creek in the back of the property to both walk and to drive across on the ATV, the John Deere and, now, the Ranger; and, 2) we needed a use for the large trunks of the huge juniper trees we planned to clear from the land (see Speaking from the Ranch post of September 29, 2010). Putting those two needs together, the cedar bridge plan was born.
In 2006 we cut down four very large cedar trees (with help from son-in-law Michael and his friend Tommy) in the area in front of the dogwood trees along the creek. Very little grass grew in this area due to the dense shade of the cedar trees. Once the trees were down, we chopped off all of the limbs and burned them in the usual brush burning pit. Four large cedar trunks were left. Rather than cutting those trunks into logs by cutting perpendicular through the trunk, using a special attachment on the chainsaw, we cut parallel to the trunk to create lumber. We cut both boards to use as beams to span the creek and thin wide planks for the decking on the bridge. Both Marcus and friend Larry assisted with the planking, but Ronnie and I did most of it.
 |
| Marcus and the planking |
This was hard, dusty work requiring helmets with face shields and ear muffs. I also wore a face mask over my nose and mouth to reduce allergic reaction to cedar sawdust – that is potent stuff!
The bridge was designed on paper with the help of architect son Marcus. Although not a civil or structural engineer, as an architect he has an understanding of structure, stress, support and design. Over the last three years, the bridge was designed, re-designed, design-enhanced, design-modified, design-improved and ultimately, probably, over-designed. Although we initially wanted to only use cedar from the property, the new and improved design required adding plywood and other boards to ensure proper strength to support the equipment that we plan to drive over the cedar bridge.

The span of the bridge is 32’ from bank to bank over a creek bed six feet below. The bridge will be six feet wide with two trusses on each side and two strong center beams all resting on large cedar logs as footers embedded in each bank. We dug the holes for the footers with my father's old heavy pickaxe that is so heavy after a few "swings" I was out of breath and had to rest. It's a heavy duty tool and did the trick with Ronnie and me switching-off using the pickaxe.

Thanksgiving Weekend at Dogwood
Thanksgiving is great time at Dogwood. Besides having the long weekend, the weather is usually cool enough to enjoy the warmth of a campfire but not too cold to enjoy activates away from the fire. Some trees have shed all of their leaves, while others are in various states of changing color. The dogwood and rusty blackhaw trees display brilliant red foliage, almost as dramatic as the fall color of the poison ivy hanging high in the trees. The pasture was shred last week so the remnants of the snow-on-the-prairie, broomweed and stalks of the KR bluestem were mowed over and no longer hip high. Zipping through the pasture in the Ranger or on the ATV is much more fun than when the grass and weeds are cut down.
After a nice family Thanksgiving feast in Houston (actually Pearland this year) we headed out to Dogwood Friday morning. We mostly worked on the cedar bridge construction project on Friday, finishing the first truss late in the afternoon. We were so busy; we didn’t even get our usual afternoon nap in our lounge chairs under the trees. For lunch we roasted hotdogs over the campfire in our work area on the edge of the woods. Oak smoked campfire roasted hotdogs with yellow mustard and pickle relish may not strike most as a gourmet meal to savor, but after working hard in the woods and thinking about an afternoon of hard work ahead, those dogs were delicious!
On Saturday morning, after watching the sun come up and start shining through the trees while we had our morning coffee and breakfast around the campfire, we decided we needed a break from bridge construction. Instead of starting the second truss as we should, we decided on an impromptu project; clearing the last cedar trees growing along the fence line between Old Dogwood and New Dogwood. We started work about 9:00 a.m. using the chain saw to cut the trees so that they fell on the New Dogwood side of the fence. Using the umpf of the Ranger and a strong rope, we dragged the trees into the pasture far enough from the woods to safety burn the cedar next year, and piled them up into a giant brush pile. We can’t burn them now as there is a burn ban in the county due the dry weather, plus, the trees don’t burn so well when they are green. Some of the trees were too heavy for the Ranger to pull so we cut those cedar in half to drag.
The main objective of this project was to remove the visual barrier created by the cedar so we can look up the hill at the magnificent oak trees we cleared a few weeks ago. It is a dramatic difference and gave us instant gratification in seeing results of hard work right away.
As we worked, we commented that on such a glorious, cloudless, cool fall day it was a shame no one else in the family was enjoying it with us. About 11:00 a.m. while clearing the fence, we got a call from Houston. Pat, Pete, Gail and Kevin decided to come out for a day at the ranch. We hurried the next two hours to complete the fence clearing and cedar dragging so that we would be ready to relax when the guests arrived. We cleared and dragged to the brush pile 13 cedar trees from the fence line by 1:00 p.m. when we declared the job a success.
Once everyone arrived and ate their picnic lunch, we gave tours of the property in the Ranger as none had seen New Dogwood. We tooled around in the pasture, around the mature oak trees that are cleared and those that are not, to the pond on the top of the hill and over by the barn. Kevin enjoyed tending the fire and throwing in sticks, just like the nephews and most little boys (including those like Kevin that are grown professional men!). Gail took photos and rest of us relaxed around the fire, with Pete and Ronnie taking breaks to check on the Arkansas v LSU football game.
It is fascinating to see how people gradually relax when they are outdoors on such a gorgeous day, in the trees and hanging around a campfire – being outdoors and away from the noise and hustle of the city, even for just a few hours, is just good for the spirit.

Mighty Live Oak Trees
In Texas, live oaks developed and adaptation to Texas soils and environmental conditions that are not conducive for propagation from the acorns. Acorns depend on animals and birds to carry the acorns away from the parent tree. Parent live oaks, to reduce competition from their offspring, encourage a fungus in the soil under the canopy to kill the germination of the acorns. What Texas live oaks do to reproduce, is they send up root sprouts from mature roots. Because the new shoot has access to the mature root system of the parent tree, survival rates are high. Many of these “cloned” sprouts from groves or “motts” as they are call in Texas that can consist of hundreds of trees that all share the same root system. These trees are a subset of live oak called Quercus virginiana var. fusiformis.
A testament to the live oak’s hardwood quality is the War of 1812 Navy vessel U.S.S. Constitution. Its frame was constructed from Southern live oak wood harvested from St. Simons Island, Georgia. The ship survived harsh British war ships' cannon balls that reportedly bounced right off the ship due to the live oak wood’s strength and density – thus the Constitution’s nickname "Old Ironsides" is due to the quality of live oak wood.
Although the brush under the live oak trees provide good cover for deer and a variety of birds, Dogwood’s mature oaks are to majestic and beautiful up on the hill not clear out underneath them to show case the trees. We have made the decision to clear out oaks and provide other cover and resources to make the deer happy.
Once cleared, these marvelous trees are and will be crowning jewels on the hill at Dogwood. So far, we cleared five live oaks. The process began with our now good friend Remedy mixed with water and a little dish soap in sprayer. In the heat of the summer, I sprayed the yaupon and juniper brush that choked and hid the oak trunks and that were growing up into the oak canopy. Mixed with the yaupon and juniper, green vines sporting vicious sharp thorns grew into the brush creating a nasty tangle. We mostly just call these vines “pokey vines” but when blood is drawn from being poked, scratched or tangled up in one, we use other descriptors not appropriate for post on this site. Taking care not the get the poison on the oak or any of its exposed roots, I sprayed the pokey vines also.
Since summer, the Remedy did its job and killed or severely weakened the yaupon and cedar. Over the course of two weekends this fall, we cleaned out the dead brush and that which was missed with Remedy. Unfortunately, I did not take “before” photos before the Remedy treatment, but I did take before and after shots of the clearing work but these will give you an idea of the diffrerence. Also, why Blogger makes it so difficult to place photos in the blog, I don't know but it is.

The Dirt on Dogwood
Young field geologists quickly learn that although using a rock hammer to whack a chip off a rock outcrop and examining it through a field magnifying glass is an important investigative step, so is stepping back to take a good look at the overall landscape, horizon to horizon. In my field geology training days (so many years ago I don’t care to reveal the number) I learned to generally survey the field area with a broad 360 degree view before bending down to hammer on rocks, squirt hydrochloric acid on them to see if the liquid effervesces or scratch around for fossils. Taking in the big picture first may reveal changes in vegetation within the field area that give clues to the geology. Such changes could be that one type of tree dominates the hilltop while another dominates the hillside or a certain grass thrives on one side of a gully and scrub brush on the other. These vegetation changes, if naturally occurring, are due to some change from one micro-environment to another – usually soil composition or water availability.
We see similar micro-environments in the soils at Dogwood Ranch and how they impact the vegetation. Visiting Dogwood Ranch for a walk or drive through the property is the best way to appreciate these changes but the next best way is to look at an aerial photograph with a soil survey map overlay.
The National Resources Conservation Service (“NRCS”) division of the United States Agricultural Department (“USDA”) runs the Web Soil Survey, a free online service that will instantly generate a soil map of a designated area up to 10,000 square acres. http://websoilsurvey.nrcs.usda.gov/app/HomePage.htm.
This website also provides valuable information about each soil type on the map, including information about irrigation, surface water sources, water table depths, chemical composition of the soil, how different building material can be effected by the soil type, sanitation issues, natural resources available, wildlife suitability and a great deal more.
In my Web Soil Survey, I designated Dogwood Ranch as the Area of Interest (“AOI”) and then generated a soil survey map.
Dogwood has five soil types; although two are the same soil composition but have different slopes so the map puts them in different categories.
Soil # Soil Description Acres in AOI % of AOI
8 Bosque clay loam, frequently flooded 5.7 12.2%
25 Crockett fine sandy loam, 1-5% slopes 24.0 51.3%
26 Crockett fine sandy loam, 5-10% slopes, eroded 7.4 15.7%
32 Frelsburg clay, 3-5 % slopes 8.9 19.0%
66 Tremona loamy fine sand, 1-5% slopes 0.8 1.8%
Soil 8 is on what we call “Old Dogwood”, the original 10 acre tract. Although the description says “frequently flooded” to our knowledge is has never flooded but during a heavy rain, ankle deep water runs from the adjoining pasture across area 8 to the creek.
Growing in Soil 8 is a great diversity in vegetation, including large trees such as red oak, water oak, American elm, cedar elm, pecan, hackberry, mulberry, Mexican plum and, of course, flowering dogwood. Notably, there are no live oak trees in this soil and the one pine “Christmas” tree was planted by the prior owners.
Soil 32 covers all of the open pasture and a little patch on Old Dogwood. This is the Freslburg clay which is basically the left over soil from weathering of calcareous shale and marl. There are no large trees growing area 32 but we did chop down a mesquite tree in the area. The clay is classic Blackland Prairie soil good for supporting grasses and forbs but not so great for mighty live oak trees. In the section of Soil 32 on Old Dogwood, there are 4 small live oak trees. I believe they were planted by the prior owners.
Soils 25 & 26 are both Crockett fine sandy loam, but only sandy in the top seven inches. From seven to 51 inches deep, the soil is clay, creating a claypan under the sand. This means that rain water can seep through the top seven inches of the sandy loam but then reaches what is effectively impermeable clay. The upper layer of sandy loam soil fills with water so if the water cannot seep into or below the claypan fast enough during a heavy rain, the water runs-off the surface onto Old Dogwood (Soil 8) and into the creek. The differences between Soils 25 & 26 is the slope and Soil 26 is more eroded than 25; the composition is the same. Nearly all of the live oak trees, some that must be close to 100 years old, are in Soil 25 & 26.
There is just a little patch of Soil 66 on Dogwood. It is the sandiest of the soils on Dogwood but still contains some clay. There are no trees in this area, only grass and forbs. This history of this general area of the property is that it was fenced years ago from the rest of the property as hay- storage area so perhaps any trees were chopped down years ago.
Careful consideration of the soil information from the Web Soil Survey will be necessary before any significant infrastructure projects begin as constructing a driveway or building on a concrete slab.
Just like the young field geologist using the vegitation patterns to get clues about the geology of the area, we can see the effect of different soil types on Dogwood Ranch by the plants that grow in each. Come visit to see for yourself.

Expert Advice from the State of Texas
Expert advice is what we needed. That’s what we sought last week by inviting Larry Pierce, County Extension Agent- Agriculture/Natural Resources Texas Washington County, and Stephanie Damron, a Texas Parks and Wildlife Department Natural Resources Specialist to visit Dogwood Ranch. We asked for their advice about how to better manage the pasture for cattle and for wildlife.
Our neighbor’s pasture is adjacent to ours and not fenced from our property since we jointly own the cattle herd with the neighbor and the cattle run freely over both properties. The property line is marked by the surveyor’s stakes when the combined 80-acre track was subdivided into our 40-acre track and the neighbor’s 40 acres. Last March, the neighbor lightly disked his pasture. We’ve watched with interest the progress of the grass on his side of the property line all spring and summer. In late summer, the grass in his pastures put-up tall stems with seed heads that waive in the breeze. Now the grass is a light tan color and looks like amber waves of grain. Its pretty and, I admit, we developed a bit of "grass-envy." The entire disked pasture consists of this grass with the tall stems and turkey-foot seed heads. There are very few other grasses or plants in his pasture now.
Our pasture right next to his is full of flowering weeds. Weeds three feet high, some with white flowers, some with little yellow flowers and a pale green leafy plant dominate. There is also some grass of the type on the neighbor’s place and a few other grasses. When we drive through the pasture on the Ranger or ATV, we stir-up bugs, grasshoppers and birds. One time we surprised a white-tailed deer doe and her fawn hiding in the weeds. Inevitably, one or both of us starts to sneeze! Our pasture is somewhat unsightly with weeds the cows won’t eat.
As we stood with Larry and Stephanie on the property line they compared the pastures, Larry from an agricultural perspective and Stephanie from a wildlife perspective. They quickly identified the grass on the neighbor’s place is King Ranch bluestem (Bothriochloa ischaemum, var songarcia). The name sounds very Texas-ish but don’t let the name or good looks fool you. Larry explained that KR Bluestem is a noxious invasive grass imported from Asia and Central Europe. It was primarily brought into South Texas (by the King Ranch folks) in the 1920s and 1930s for its drought resistant qualities. When cotton farming declined in Washington County, Texas due to economics and a cotton root fungus in the soil, KR bluestem was introduced to prevent erosion. According to Larry, folks at the time thought that KR bluestem would save the soil, save the county, save Texas and thus save the world!
Things did not turn out that way. KR bluestem took hold rapidly, pushed the out the native grasses in the prairie remnants that remained in the area and invaded, creating single species grass fields. To make matters worse, KR bluestem is only marginally beneficial to cattle and has little advantage for native wildlife. Larry explained that disking a field to encourage KR bluestem, as our neighbor did, only slightly improved the pasture for cattle grazing. Cows will eat it but it is not their favorite dish.
Asked how to control KR bluestem, Larry explained that so far researchers have not found an effective means to control the grass. Sprays of extremely high Round-Up concentrations can knock it back but the grass tends to grow back. Other usual methods of controlling grasses have not been successful in controlling KR bluestem. Research continues.
Turning to our pasture, Stephanie explained that from a wildlife standpoint, our pasture was a good habitat for prairie birds. She pointed to three good seed sources: common broomweed (Xanthocephalum dracunculoides), snow-on-the-prairie (Euphorbia bicolor) and Texas croton (Croton texensis). Broomweed and croton are forbs, which are non-woody flowering broad leaf plants that are not grass. Snow-on-the-prairie is a euphorbia, kin to succulents and poinsettias. The white “flower” giving the plant its name “snow on the prairie” is not really a flower but is nonetheless referred to as a “wild flower”.
When the snow-on-the-prairie plants were tall and blanketed the field with white blooms in July and August, we noticed the cattle would not even walk through that portion of the pasture. The reason is that the plant is a euphorbia and like all euphorbia, has a milky white substance in its stems which is an irritant, especially to the eyes. It is poisonous if ingested. Cows aren’t particularly smart, but I guess they aren’t so stupid as to eat poisonous plants. Now that the “snow” has melted, so to speak, with the white flowers gone and stems dried, the cows will graze on grass through this area of the pasture. In addition to the croton, snow and broomweed, our pasture has KR bluestem and some sprigs of the native prairie grass silver bluestem (Bothriochloa saccharoides var. torreyana).
After talking with Larry and Stephanie, we’ve decided that we don’t want encourage the KR bluestem to take a stronger grip on our pasture. Eventually we plan to convert the pasture to native prairie grasses that both cattle and wildlife prefer. We realize now that this may be an even bigger challenge than we anticipated as first we have to knock back the KR bluestem enough for other grasses to have a chance. Then the restoration area must be fenced off from the cattle who will eat the new grass as it comes up preventing the grass from becoming established.
Larry and Stephanie also discussed state and federal programs available to assist landowners with certain agricultural and wildlife activities. We are going to look into those in more detail. They also strongly recommended that we meet with a local representative from the U.S. Department of Agricultural who they say is the most knowable about soil and erosion concerns and federal programs to assist landowners with these issues. We have some erosional features on the property that we need to address.
We also inquired about why, over the last 18 months, large mature oak trees that looked healthy on Old Dogwood fell over, full of green leaves. Larry’s suspicion is a cotton root rot fungus that still infects the soil in the area from days when cotton was king. He also suggested we get the local U.S. Forestry Service representative out to look at the woods on Dogwood Ranch which he believes are unique in area.
I am now reaching out to those federal resources to investigate further what we should or should not do with the land and what assistance, if any, is available to assist us (without too many federal government strings attached!).
Our neighbor’s pasture is adjacent to ours and not fenced from our property since we jointly own the cattle herd with the neighbor and the cattle run freely over both properties. The property line is marked by the surveyor’s stakes when the combined 80-acre track was subdivided into our 40-acre track and the neighbor’s 40 acres. Last March, the neighbor lightly disked his pasture. We’ve watched with interest the progress of the grass on his side of the property line all spring and summer. In late summer, the grass in his pastures put-up tall stems with seed heads that waive in the breeze. Now the grass is a light tan color and looks like amber waves of grain. Its pretty and, I admit, we developed a bit of "grass-envy." The entire disked pasture consists of this grass with the tall stems and turkey-foot seed heads. There are very few other grasses or plants in his pasture now.

The Rainbow Bridge
Old Dogwood has a seasonal creek that divides the property 1/3 on the “other side” of the creek and 2/3 on the driveway side of the creek. The “other side” is heavily wooded and the wild side. From about May through December, the creek is dry with white sand in the bed which varies from a few feet deep to over 10 feet deep in the area we call the “Grand Canyon of Dogwood.” From January to April it often has a small stream of water trickling down about ankle deep in most places. The creek rises quickly during a heavy rain, up to several feet deep.
Soon after we acquired Old Dogwood, we realized we needed a way to easily cross the creek, dry or wet. We also wanted to take equipment and the mower to other side. To do that, we needed a bridge. We decide to build a rainbow or arch-type bridge to span 25 feet across the creek with a seven foot width. Like with nearly everything these days, bridges are for sell over the internet. A nice fellow, Frank Petersohn, in Sechelt, British Columbia, Canada had a rainbow bridge design for sell via the internet. Browse his website at http://mathemati.ca
We gave Frank the bridge dimensions we wanted and that it should support 1600 pounds. He modified his design accordingly, cut the lumber to size with the correct angles for assembly, provided the hardware to hold it all together and assembly instructions. The only lumber not provided were the planks as those were standard size and easily purchased at any lumber yard or home improvement store.
The bridge pieces were shipped by freight to us and delivered to our gate at Dogwood. On our usual route from Highway 290 to Dogwood, there is a small wooden bridge over a creek. The bridge is not marked with a load capacity. When the freight truck driver got to that bridge on his way to deliver our bridge, he refused to cross the unmarked bridge for fear it would not hold his truck and his load. He called his dispatcher to find him another back road route to Dogwood. The bridge was transfered from the freight truck to our truck for the 50 foot drive from the gate to the garage.
We decided to build the bridge in the front part of the property and built most of it during December 2003 when there was no water in the creek and the weather was not too hot to work hard. Before the building could begin, concrete footers were constructed on both banks to support the bridge. Frank’s site shows in detail how those were to be constructed.
We did this by digging a hole 2 feet wide, 6 feet long, and 2 feet deep and filling it with cement. Each footer required 12 80-lb bags of cement. Getting 12 8-lb bags of cement across the creek was a challenge. Each bag was wheeled over and pushed up the bank in a wheel barrow one at a time. To wet the cement, we strung three long garden water hoses from the well house, across the property and across the creek to the footer location. Rebar was added to the wet cement slurry for strength.

The bridge was then constructed per the designer’s recommendations. By Christmas 2003, we had an attractive bridge and a way to drive across the creek! It has served us well over the last seven years and remains sturdy. It official opening ceremony with family was in February 2004.

Go to Frank’s site, click on photos and the Dogwood bridge is featured in the third column, the fifth picture down. http://mathemati.ca/1_24foot.html
The bridge was a big project, one of the first of many at Old Dogwood needed simply to make the place more habitable and easier to get around. However, today, if we drive the mower or ATV over the bridge, we cannot complete the loop and cross back at the other end of the property because we do not have a bridge in the back of the property. That is about to change and we hope to complete the next bridge project by the end of 2010. It is a different type of bridge and will be built from different material. The Cedar Bridge Project has been underway for two years but the construction phase soon begins.

Installing the Diffuser
Installing the pond diffuser was a six-Advil project: two before starting work, two after finishing the work and two more at bedtime that night. It was also a two-hardware-store-visit job during the middle of the project.
An objective during this installation was for neither of us to get in the water at all! Although the fish, turtles, frogs, deer, birds and other wildlife like this water and it is safe and beneficial to them, it is not fit for human swimming or for human ingestion.
First, take a look at the diffuser and the air pump in the photos below.
We ordered an electric genAir 484 that is designed to run constantly for seven years. The diffuser itself is a fairly simple device and hooking it up was not difficult. The green box is the air pump. The black tubing is hooked to the pump and the other end is hooked to the diffuser, the black square with the two round pieces attached on top. When the air pump is on, air flows through the tube and blows out the tiny holes in the two disks.
After wiring an electrical outlet in the well house (using supplies left by Dogwood’s prior owners) and finding a stable surface for the pump and testing it, we ran the 50’ weighted tubing that came with the diffuser from the pump in the well house down the slope toward the pond. Oops! The 50’ of tubing just barely reached the waters’ edge. To get the diffuser set even close to the center of the pond, we needed at least another 50’ of tubing; thus, the trip to the first hardware store. Since we figured the local hardware store would not have the specialized weighted tubing meant to sit is water for years, we decided to buy whatever proper sized tubing we could find and bury it from the well house to the pond in one inch PCV electrical pipe. We would fasten the weighted tubing that came with the diffuser to the end of hardware store tubing, hook it to the diffuse and run it out in the pond.
I started at Tractor Supply up on highway 290 just east of Brenham. I found a 50’ coil of the right size tubing but it was designed to spray agricultural liquid chemicals. I got it along with several sizes of clamps and couplings. I also made four calls back the Dogwood to make sure I was buying the right stuff. Unfortunately, Tractor Supply does not carry PVC pipe so, it was off to the local Home Depot where I bought 50’ of electrical PVC pipe which we could easily connect together. The sales staff at the Brenham Home Depot is very helpful and friendly, much more so than in the Houston Home Depot stores.
Meanwhile, back at the Ranch, Ronnie started the real work – digging the 50’ trench from the well house to the pond to bury the line so the cows don’t step on it and crush it or pull out the connections. What made this job so hard is the “black gumbo” soil on Old Dogwood. When it’s wet, it is gooey and sticky – it cakes on your boots making them heavy and it won’t drop-off the shovel unless scraped off. Digging and scraping makes for hard slow digging. But, when the gumbo is dry, it seems hard as cement and takes a pick axe to make any headway. That’s how it was digging this trench; it was dry, hard like cement. We took turns using that heavy pick-ax and then scoping out the dirt. I can’t swing the pick-ax because it is so heavy so I just hack at the ground. We dug the trench just a few inches deep.
We decided that before finishing the trench and burying the pipe, we should deploy the diffuser in the pond. To do that, we hooked the air tubing together and to the diffuser, filled the diffuser base with sand (dug from a dry creek bed in the woods up the hill), put the plug in and tied a rope onto the diffuser base. To the end of that rope, we tied a longer rope. While one of us held the tubing in place at the end of the trench, the other took the long rope and walked to the other side of the pond. Once we were right across from each other, Ronnie slowly pulled the rope toward the other side of the pond and diffuser slowly sunk into the pond blowing bubbles. We had it turned on so we could see where it was as it moved underwater. As Ronnie pulled on the rope the diffuser moved toward the center of the pond. When all of the slack was nearly out of the tubing, we stopped and let the diffuser settle into the muck on the bottom, blowing bubbles all along. I was pretty impressed we managed to get it done without either of us getting wet! The diffuser is not quit in the center of the pond but close enough to do the job.
An objective during this installation was for neither of us to get in the water at all! Although the fish, turtles, frogs, deer, birds and other wildlife like this water and it is safe and beneficial to them, it is not fit for human swimming or for human ingestion.

The next morning we finished digging the trench. Worried that once the pond filled to capacity again the PVC might float up our of the trench, we used some old cinder blocks and cinder block pieces to hold the pipe in place. We ran the PVC through the holes in the cinder blocks and buried them in the trench.

The change in the pond is going to take some getting used to. The bubbling on the surface of the water is fairly gentle but every now and then it gurgles and splashes. At times it sounded like the creature from the Black Lagoon starting to rise out of the water! We hope that when the pond is full, there will be a bit less splashing but it’s really not loud, just different. Our next task is to determine if we need to restock with fish and if so, what kind.
