Sagebrush ecosystem recovery hobbled by loss of soil complexity at development sites

26 enero 2015

In big sagebrush country, re-establishing the ecosystem’s namesake shrub may jump-start the recovery process more successfully after oil and gas development than sowing grass-dominated reclamation seed mixes typically used to quickly re-vegetate bare soil on well pads, report two Colorado scientists. Big sagebrush is often conspicuously absent at restoration sites decades after disturbance. Historically, grasses have dominated the vegetation recovery following development, offering limited diversity and poor quality habitat for the 350 wildlife species harbored by what was once the most widespread ecosystem in the western United States.
