Are Certain Native Grasses More Resilient To Drought?

Native Grass Selection for Drought Prone Areas

When selecting native grasses for upland bird habitat restoration, it’s essential to choose species that are tolerant of drought and have deep roots to access water deeper in the soil profile. In the Great Plains region of North America, for example, warm-season grasses such as blue grama (Bouteloua gracilis) and little bluestem (Andropogon scoparius) are well-suited for areas with low precipitation. These species have deep roots that can access water up to 6 feet deep, allowing them to survive with minimal rainfall.

Planting Techniques for Drought Tolerance

To enhance the drought tolerance of native grasses, it’s essential to use proper planting techniques. Planting native grasses in the fall, when the soil temperature is cooler, can help reduce transplant shock and promote root growth. Additionally, incorporating organic matter such as compost or manure into the soil can improve its water-holding capacity and promote soil biota. A seeding rate of 10-15 pounds per acre is recommended for warm-season grasses, with a mix of 50-70% grass species and 30-50% legume species to provide nitrogen fixation.

Habitat Management for Drought-Resistant Grasses

To ensure the long-term success of native grasses in drought-prone areas, it’s essential to implement effective habitat management practices. This includes maintaining a prescribed burn schedule to promote grass growth and reduce woody encroachment, as well as controlling invasive species that can outcompete native grasses. By following these practices, land managers can create a resilient and drought-tolerant habitat that supports the needs of upland birds and other wildlife.
