Another Poverty Grass

E-mail Print PDF

By Jake Landers

Published July 2013

Jake Landers Bleached and weathered Red threeawn grows in clusters around a Harvester ant bed where it can become established without being destroyed by the ants. Might as well continue with another depressing range story because at the time of this writing it looks like the hot dry spring will continue into a hotter and drier summer.  I hope I’m wrong.

Recovery of our grazing lands at this time depends 99 % on rainfall and 1% on management, but it’s always good to think about the plants that we need to know more about in our attempt to make ranching a sustainable enterprise.

Red threeawn is another poverty grass.  Its leaves are short and thin without much to graze on.   It matures in a hurry and quickly looses any forage value for livestock.  Once it was more common on the ranch than it is now.   I remember seeing a sea of red on our Mesquite flats in early summer when the grass was full of seed heads.  The red comes from the long awns or tails of the seeds which are important in pushing the seed into the soil to establish a new plant (and, unfortunately, into the wool and hair of sheep and goats).  Why they are red defies explanation, for sure it’s not to attract pollinators.  All grasses are wind pollinated, and there is no need for color, attractive odor, or nectar to attract Butterflies and Bees.

Monstrous Red threeawn grass grows in town with abundant water, plenty of sunshine, and no  competition. Red threeawn takes advantage of soil disturbance to get established.  Heavy grazing and drought that destroy the turf allow the seeds to penetrate the soil and benefit from the light showers that wet the top of the ground.   Individual plants last a few years, and with time, they are replaced with better adapted plants, depending on available seed, adequate moisture and protection from heavy grazing.  I’m confident the abundant plants I remember were established in the 1930’s and again in the 50’s and were less obvious as Dad became a better manager.

Red threeawn, sometimes called Purple threeawn, has the scientific name of Aristida purpurea var. longiseta.  It extends from Canada to northern Mexico as a rather variable plant.  In recent years it has been grouped with one big taxonomic mess of perennial threeawns consisting of about seven species, now varieties, in Aristida pupurea.

Today on the ranch it exists as a minor species.  Red threeawn establishes easily on two rather different soil conditions.  On a repeatedly overgrazed Mesquite flat it can be a dominant grass, a red carpet when the seedheads are ripe.  And it can be the only grass growing on Harvester ant beds.  It is easy to spot an ant bed in the pasture every 100 feet or so by the Red threeawn, which because of the weather has been bleached to straw color, no longer red.

The part of the ranch that I inherited was extremely overgrazed in 1938 when Dad acquired it.  Under his management he has left it better than he found it, and I am intent on doing the same.  And that means less Red threeawn and the other poverty grasses: Texas grama, Red grama, and Hairy tridens.   



Reading The Landscape

A Edwards Plateau pasture in dry winter. What kind of tree is prominent in the center?  What is the dark gray green understory shrub? What is the green plant in the fenceline?

Reading the Landscape: Answer

Jake’s comments: The tree is Chittamwood or Gum Bumelia which reacts to Mistletoe by making “witches broom” clusters; beneath is Algerita; green plant in fenceline is Sacahuista or Beargrass, poisonous to sheep and goats in spring.  It appears to be a well managed pasture with a bit too much Algerita.       —JL

The Poverty Three

By Jake Landers

Published June 2013

Jake Landers Texas grama is starting to fill in some of the bare ground as the drought continues on central Texas rangeland. A rancher who depends on Hairy tridens, Red grama, and Texas grama for forage production for livestock is on the road to poverty.   They are the first to recover from a drought, usually from remnants of a root system, but also from seeds produced even during the worst drought conditions.  They survive because they are small enough to avoid grazing by cattle, and the close nibbling by sheep doesn’t take a killing amount of leaves.

Two Brush Country Survivors

By Jake Landers

Published May 2013

Jake Landers Hawthorn’s flowers appear in spring before its leaves. They stand out in a thicket of Shinoak Two woody plants surviving in the Shinoak thickets and other brushy areas of the Hill Country are White honeysuckle and Hawthorn—not often recognized by local residents.  Both have attractive white flowers in the spring and red fruit in the fall, but their scattered distribution doesn’t provide much exposure to the viewing public.  Most of the time I see them across the fence, blooming, or with red fruit, as I go by at the speed limit on one of our good Texas highways.

Hunt for the Red Green Condalia

E-mail Print PDF

By Jake Landers

Published April 2013

Jake Landers Geen Condalia develops a few black berries throughout the summer. Some years ago the late R.J. Godfrey parked his pickup beside mine and showed me a thorny plant that almost filled his pickup bed.  “What is it, and how can you kill it?” he asked.  I identified it as Green Condalia and told him what I thought would kill it.  I cut off a piece of the butt end to determine its age, and I noticed that the heartwood was dark red.  I told him that I would dump it out on my brush pile, suggesting that next time he didn’t have to bring me the whole plant for me to identify.  He was glad to get rid of it on the ranch, was his closing comment.

Bristlegrass

E-mail Print PDF

By Jake Landers

Published March 2013

Jake Landers Southwestern bristlegrass grows in August in shadow of building in downtown Menard, Texas, on ancient floodplain soils. We have several native perennial Bristlegrasses that are important in our pastures.  We also have a bunch of annuals we received from the Old World.  The natives are rancher friendly, but the aliens are aggravating to farmers as weeds in crops and fields, and one of them is especially aggravating to me in my garden.

Southwestern bristlegrass in our deep soils is the largest of the natives with Plains bristlegrass smaller and more widespread in our rangeland.  Grisebach bristlegrass is in between and sometimes overlaps in appearance with Southwestern bristlegrass to make identification untrustworthy.   Knotroot bristlegrass is similar to Plains with knotty roots.
