Northeast Research and Demonstration Farm
The decline of pollinators throughout the United States recently has prompted the USDA to create a conservation program designed to promote pollinator habitat. For the popular CP-42 pollinator program, conservation practice specifications intend to create forb-dominated stands of native vegetation that support pollinator use. As part of these specifications, seed mixes are required to have an overall seeding rate of 40 seeds/square ft, with a grass-to-forb ratio of 1:3 (10 seeds/square ft grass and 30 seeds/square ft forb). As interest in the CP-42 program has grown, seed vendors and other organizations have provided pre-packaged seed mixes to meet these program requirements, and practitioners have planted thousands of acres of such seed mixes over the past several years.
