The importance of carefully monitoring rangeland conditions is essential when working with grazing lands. Conditions or issues can be averted or at least addressed if the grazing manager is closely watching the rangeland and livestock performance. As the picture of Indian grass shows, this once healthy-vigorous plant (Photo 2) has become moribund and has ceased to be a healthy contributor to the rangelands improving health. The dark brown to black area is what used to be a thriving Indian grass plant, due to lack of animal impact or any other disturbance to cause new growth nodes to produce new growth the leaf structure has slowly died. (Note the center of the plant has hollowed out with dead material.) Yet in its struggle to survive green shoots of new growth are occurring. Think what the root structure must look like, probably much like what we see on the surface.
The second picture is of the same plant or plants three years earlier, a dramatic change at best. What happened? Low density grazing? Rest period to long? Drought? Manager needs to step up his management program? Possibly all the above except for drought, which many times is wrongly given the blame for management mistakes. Indian grass and its deep strong root system is one of the most drought tolerant grasses out there, provided the grazing program is adapted to its health requirements. Graze-Rest-Graze-Rest.
The Better it Gets the Faster it Gets Better. UNLESS
On the first of September much of the rangeland that we operate will have been green for more than 130 days. This has been an unheard-of grass growing event with the relatively cool summer with no big rainfall events, however well timed and productive smaller rains have provided the growing event of a lifetime. Yes, this has been extremely beneficial for all ranchers in the area and those that are working with a well-planned graze-rest program have produced rangeland conditions riveling perhaps the best in many grazers’ lifetime. Following through and continuing with the graze-rest programs will move those ranchmen’s management endeavors to new heights.
While the assumption can be made that grazing conditions are not like Charlie Goodnight saw when traveling through the Concho’s in 1857, the pictures depict, perhaps, a small glimpse of what he saw. (Perhaps less the cedar trees) Sideoats, Little Blue, Bush Sunflower, Indian Grass, Old World Bluestems (That Charlie certainly didn’t see as they are introduced plants) and numerous others of small population but of equal importance, provide the diversity essential for building soil health, storing of carbon and environmentally sound grasslands.
Many times, a rancher makes the statement that “not much will grow on these rocks”. Time and effective grazing management practices are proving this to be incorrect. Proper length of rest and grazing of those rocky areas are proving to be among the first areas to show dramatic improvement. Big Bluestem, Little Bluestem, Indian Grass, and others of the deeper-rooted grasses seem to like the fractured limestone rocks of West Texas and some of the rockier areas that show little topsoil are beginning to team with good cover of healthy plants.
Why is this taking place? Maybe the rocks at the surface concentrate the limited rainfall. Maybe those rocks help protect new and even older plants from grazing. Perhaps the slopes and draws where the rocks seem to be most prevalent, concentrate the rainfall in areas that used to be streams and creeks of flowing water, providing more moisture for growth.
As the pictures depict: Big Blue seems to like the same areas as the shin oak prefers, much the same as a former post showed of Indiangrass. Granted the Big Blue pictured are young plants that have grown with the rare occurrence of this year’s almost ideal growing conditions. (Hopefully your area has been blessed with this ‘anomaly’.) It will be exciting to watch over time to see if these youngsters survive the drought like conditions that are sure to follow this growing event. With the continuation of the graze-rest program I am betting they do.
Exciting things are happening on rangeland that has been properly cared for through utilization of a carefully planned and applied graze-rest program. The recent rainfall across the area, granted more in places than other, is proving exceptionally valuable on areas that have a continuous cover of healthy perennial grass plants. Even the places that received sparser amounts of moisture are showing amazing recovery from the limited rainfall of late winter and spring. Regretfully, but fully expected, the areas that have not recovered from past continuous and sometimes heavy grazing are struggling to achieve the growth needed to allow the rangeland manager to be assured of good grazing through the summer season. Leaving that producer dependent of “a good follow-up rain soon” of course all concerned will thankfully take it if the Lord sees fit to send it. Recovery of rangeland is a slow process and is directly proportional to the brittleness (Total rainfall and low humidity levels) of the environment the rangeland manager is working within.
