Do Certain Grasses Provide Better Cover For Nests?

Native Grass Restoration for Upland Birds

Native grass restoration is crucial for maintaining healthy ecosystems and supporting upland bird populations. In particular, warm-season grasses like big bluestem (Andropogon gerardii), indiangrass (Sorghastrum nutans), and switchgrass (Panicum virgatum) are excellent choices for nesting cover. These grasses typically grow 3-7 feet tall, providing a dense canopy that shields nests from predators and harsh weather conditions.

Nesting Cover Characteristics

When selecting grasses for nesting cover, look for species with the following characteristics: dense growth habits, leafy foliage, and a tendency to form dense stands. Big bluestem, for example, can form dense stands with up to 100 stems per square foot, making it an ideal choice for nesting cover. In contrast, cool-season grasses like Kentucky bluegrass (Poa pratensis) and tall fescue (Festuca arundinacea) tend to be less dense and less effective for nesting cover.

CRP and Native Grass Plantings

The Conservation Reserve Program (CRP) has played a significant role in promoting native grass restoration and upland bird conservation. To maximize the benefits of native grass plantings, it’s essential to create a diverse and dynamic ecosystem. This can be achieved by planting a mix of warm-season grasses, including big bluestem, indiangrass, and switchgrass, along with native wildflowers and forbs. By creating a diverse and dynamic ecosystem, landowners can support a wide range of wildlife species and maintain healthy soil and water resources.
