Looming drought in 2017 is a concern in Eastern Colorado. About 500,000 acres (0.7 % of Colorado) in central Lincoln County is already in severe drought. A much larger swath across the Eastern Plains counties, covering 23,560,000 acres (35.3 % of Colorado), is in moderate drought. This region has not received any meaningful precipitation since late summer. When combined with the 2017 weather outlook, ranchers and land managers have reason for unease.
To address this issue, the USDA-NRCS, CSU-Extension, and the Yuma County Conservation District partnered to put on a drought workshop at Kirk, Colorado in January. Participants from nine counties across Eastern Colorado, representing ranchers, government land managers, and CSU Extension agents. In the morning, a series of talks discussed range management under drought conditions.
Don Schoderbek, CSU Extension specialist, discussed the mechanics of range plants, how plants change during a drought, and what this all means to livestock producers. “Did you know that a grass plant sets its growing points (buds) for new growth the previous summer? This means that late summer moisture is crucial for new plant growth the following year” said Schoderbek. New growth, in turn, is critical to root survival. “This is where grazing comes in. Grazing mediates the amount of green leaf material, which supply roots with energy,” Schoderbek noted. The roots, despite being located below ground, are the ‘body’ of the plant year-to-year. Having healthy roots leads to more vigorous plants, which translates into in tougher plants during drought.
Drought is more than what happens in the rain gauge, it is a dynamic process that affects each ranch differently. It is the link between precipitation and management, according to Roy Rauth, retired CSU Professor and Extension specialist. Management actions in the good years will determine how intense the drought is. Improving plant cover is a place to start. Having higher cover allows you to ‘catch’ additional precipitation. Rauth discussed his work on the Meadow Springs Ranch near Carr, Colorado. Rauth said, “After 10 years of managing with cover as an objective, the ranch withstood the drought of 2002 without major stocking rate or surface water impacts. Ask yourself, how nice would it be to have healthy, running springs during a drought?”
Following a beef lunch, the group traveled to the Wise Ranch north of town for a pasture walk. This informal discussion looked at different areas of the pasture, and evaluated how the pasture is responding to drought. They also looked at a variety of different range plants, and how they benefit the land. Even so-called ‘nuisance’ plants like yucca, cactus, and sand sage help catch moisture. Having a diverse forage base is also better for livestock production.
