Abstract

In Iowa, over 99% of tallgrass prairie has been converted to agricultural land [2]. Increasingly intensive farming practices have recently been linked to habitat decline and reduced ecosystem services, with severe impacts on pollinator populations [4]. The Conservation Reserve Program (CRP) was established by the USDA Farm Services Agency to provide incentives for landowners who enroll farmland to be restored to prairie, with more focus on establishing pollinator habitat in recent decades [3]. For this study, wished to determine the effectiveness of CRP initiatives for several ecosystem services, including the availability of various pollinator resources throughout the season. In this experiment we assess the number of floral resources and overall species richness of mid summer blooming species, both sown and unsown, in relation to seed mix and planting time. We specifically wanted to know:

  1. How do seed mix and planting time affect the quantity and richness of floral resources in mid summer?
  2. Are there interactions between seed mix design and planting time?
  3. How does the contribution of sown and unsown species differ between seed mixes and planting times?

Effects of Seed Mix Design and Planting Time on Mid-Summer Floral Resources in CRP Plantings
