We are working on putting together a plant guide specific to Indian Creek. This is one of a series designed to help us all become familiar with our plants.
Sotol is one of the plants that is easy to recognize, with its saw-toothed leaves and 10-foot-tall flower stalks. However botanists are still not in agreement as to which plant family it belongs in – some place it with the agaves, and some with the nolinas (bear grass), and the Lady Bird Johnson Wildflower Center puts sotol in the lily family.
Some of my research sources said that it blooms every year, and others said it blooms every 2 to 3 years. However, there are 20 sub-species in northern Mexico and southwest Texas, so maybe that contributes to the conflicting information on the plant. An article from Texas Highways magazine says that the Hill Country subspecies is Dasylirion texanum. It would be interesting for us to watch for blooming patterns, and see if all the plants here bloom on the same schedule.
Regardless of differences between sub-species, sotol was an important plant for Native Americans, with useful leaves and edible hearts. You can read more about its uses in history here.
And today, it is used to make a liquor similar to tequila!

Elk are large members of the deer family which exhibit very different behavior than our whitetail deer. Elk are physically adapted to more open environments and the males gather and defend groups of females during the rut. Female elk may vary in weight from 400-500 pounds with bulls weighing 600-800. Some larger bulls may approach 900-1000 pounds in weight. These weights are for the Rocky Mountain subspecies which is the elk we have on the ranch.
Elk may live to be 10-15 years of age in the wild. One research study on the Vermejo Ranch in northeastern New Mexico reported that maximum antler growth wasn’t achieved until bulls were 10 years of age on average.
The best data available for Texas indicates that 2 “subspecies” of elk occurred in Texas historically. Merriam’s elk occurred in the Trans-Pecos region extending into northern and central Mexico. This population was contiguous with elk populations in New Mexico and Arizona.
The Manitoba elk occurred in the northern Texas Panhandle and along the Red River area. These populations constituted the plains elk which also roamed Oklahoma and Kansas into Canada. Eastern elk occurred in Arkansas but no definite records exist for their occurrence in Texas. The Texas Parks and Wildlife Department on their website state, “Historical evidence indicates that elk may have been present over much of Texas.” Elk were considered extirpated in Texas by the late 1800s. All elk in Texas today are of the Rocky Mountain subspecies from transplant stock tracing back to Yellowstone National Park.
Biologists have debated back and forth for decades whether elk and red deer are the same species. I was always trained that they were since they freely interbreed and produce fertile offspring. However, about 7 years ago they were once again reclassified as separate species.
Legally elk are considered to be livestock in Texas at the present time. This is strictly a political designation as they have also been classified as native big game (which they biologically are) and exotics at various times. Currently the neighboring states of New Mexico, Oklahoma, and Arkansas have free roaming wild herds which are managed and hunted as native big game animals.
Elk are primarily grazers but will use browse extensively when grass is not available. This is in contrast to our whitetails which are primarily dependent on browse. A good ratio for calculating range carrying capacities would be that 1 elk equals 3 deer.
The elk rut occurs in September and October with single calves being born in May and June. Elk are best known for the bugling of the males during the rut. Fights during the rut can be extremely violent with broken antlers and even death often occurring.
Most people are unaware that the cows also bugle but it is much less pronounced than the bulls.
Both sexes have the remnants of tusks in their upper jaws also referred to as the “ivories”. Sika deer which also trace their lineage back to a common ancestor with elk also have these remnant tusks. In some cases sika deer and elk may interbreed but the offspring are sterile. These offspring are referred to as “Silk”. Some game ranches have deliberately interbred them to produce a larger antlered variant of the sika for hunting.
Elk are a fairly easy animal to manage. Given sufficient space with some security cover, grass, and ample water they will usually flourish. The only common primary predator they have in our area is man.

The Rio Grande turkey is the most common of 3 sub-species of wild turkey found in Texas. Their numbers in the Edwards Plateau have actually declined since the highs of the 1980s but appear to have stabilized over the past 2 decades. Current statewide population estimates from TPWD put the number of birds statewide at about 500,000. That sounds like a lot but compare it to 3.8 million whitetail deer in Texas.
Wild turkeys on average only live 2-3 years but some individuals have lived to be 10 years of age. The three most critical components of good turkey habitat are roost sites, nesting cover, and brood habitat.
Roost sites in the Edwards Plateau are most often associated with drainages where larger trees grow due to higher moisture availability. Good roost trees have spreading horizontal branch structure and fairly open canopies that allow the birds to fly into the trees. The majority of roost sites on the ranch are large oak trees. Good roost sites also have open approach areas where the birds can detect any predators before they go to roost. It is critical not to disturb birds at the roost sites as they will abandon them with continued disturbance. It is also illegal to hunt turkeys on the roost in Texas and most states.
The most critical element in good nesting cover is tall grasses, approximately 18 inches in height. Most nests will be found in grasses near the base of some type of shrubby cover. One Texas study reported that 87% of all nests were in this type of grass cover. Most hens nest within ¼ mile of a water source.
Recent studies in Texas have shown that only 1/3 to 2/3 of hens will actually try to nest each year depending on the weather and habitat conditions. Each hen will lay an average of 9-11 eggs with up to 16 reported over a 2 week period. She will then incubate the eggs for 28 days until they hatch. A maximum of only 30-40% of the nests will be successful in hatching. The rest will be lost to weather or predation events.
The first 2 weeks of a poult’s life are also characterized by high mortality losses to a variety of causes. The poults immediately begin foraging on their own under the watchful eye of the hen. Semi-open grassy areas with high bug populations and nearby overhead cover provide good brood habitat in this stage of their life. After 2 weeks the poults can fly and will begin roosting in trees substantially increasing their chances for survival. Out of an average of 8-10 poults hatched from a nest only 2-3 are usually still alive at the end of the summer. The point here is that becoming an adult turkey is not a high percentage game for young poults even if the eggs do successfully hatch.
Once fully grown, turkeys are primarily herbivorous but will still take insects and other invertebrates. A large variety of grass seeds, fruits, nuts, and forbs make up the majority of their diet. Under severe conditions supplemental poultry feeds do seem to benefit turkeys but will not make up for poor natural habitat conditions.
Good habitat in a mosaic of open and wooded cover with available water will provide everything a turkey needs. Most recommendations suggest a 50-50 mix of open areas and brush. Some more recent research and my experience is that 30-40% seems to be sufficient. Brush is all species, not just juniper (cedar). Juniper berries are eaten by turkeys but heavy brush cover will deter turkey use since their primary defense against predators is their eyesight.
Two good publications for information are “Rio Grande Wild Turkey in Texas, Biology and Management” by the Texas AM Extension Service (publication number EB-6198, a free download), and “Texas Turkey Talk” by TPWD ( a free 14-page PDF booklet).

Dear ICR Landowners,
I hope you have all had a safe and successful hunting season. If you haven’t already, please submit your harvest information to Randy Wood. This information is extremely useful in our overall Management Plan for the ranch. You can also send the information to me and I will make sure Randy gets it.
As an Edwards County landowner, you should have received by now a letter from the Edwards County Appraisal District (ECAD)on the requirement to submit your Annual 1-D-1 Wildlife Report form to them by January 31, 2012. In addition to the report, they are requesting “supporting documentation of the management practices you have used over the last year.” Failure to submit the report could cause denial of the special valuation.
The guidelines they will use to assess the annual reports are available on the following website (provided by ECAD):Http://www.tpwd.state.tx.us/landwater/land/private/agricultural_land/ (click on the Edwards County and Cross Timbers &Prairies region)
Appendix A contains the Guidelines they will use, and Appendix U contains the Wildlife Management Plan and 1-D-1 Annual Report forms.
As in years past, documentation is the key to success when you are submitting your annual report.
