New research shows that 86% of hens avoided nesting in sagebrush habitat invaded by conifers. Luckily, the studies also show that removing conifers in otherwise high-quality habitat is a boon to nesting sage grouse.

The latest research — published in this month’s special issue of SRM’s Rangeland Ecology & Management science journal — shows the benefits of removing conifers for grouse, wildlife, and people living in sagebrush and prairie ecosystems.

Scientists tracked sage grouse nest success in southern Oregon, and found that hens avoided sites where conifer cover exceeded 3% within 800m of their nests.

Water delivery is delayed by an average of nine days in sagebrush systems compared to juniper-dominated systems. Holding water later into the summer season helps the sagebrush system become more diverse, benefiting vegetation, wildlife, and ranchers. This is one of the greatest services that an ecosystem can provide in the West.

Conifer encroachment spells bad news for birds that need intact, wide open spaces–sage grouse and lesser prairie-chickens included. This new report released by our partner, the Lesser Prairie Chicken Initiative, explains why.

A new study and a complementary video of two hens’ summer movements show that wet islands of green in the sagebrush sea provide vital foraging habitat for growing sage grouse broods.

New research released as part of the Sage Grouse Initiative’s Science to Solutions series shows that restoring sagebrush ecosystems not only benefits ranching and sage grouse but other wildlife, too, including key songbirds.

This transition from shrub steppe to woodland has broad, concerning impacts on ecosystem function and services. This fact sheet explains the “why when, where, and how” of conifer expansion in sagebrush ecosystems, and lists potential management strategies.

Hundreds of thousands of acres of intact sagebrush lands–and the grouse that depend upon them–are threatened by invading conifers. SGI helps remove the threat to prevent further loss.
