Description
This manual sets forth a method to design site-specific native grassland seed mixes with long-term resilience that will meet the multi-pronged goals of roadside vegetation. Primary goals of the site-specific native grassland seed mix design methodology presented in this manual are to: 1. Empower users of varied backgrounds, including transportation engineers and maintenance workers with limited or no knowledge about native plants, to design reliable site specific native grassland seed mixes that are well suited to their project and create grasslands that are resilient over time. 2. Allow for flexibility in species selection based on current seed availability and cost. 3. Maximize seed market demand/supply balance. 4. Result in the most diverse possible species use statewide to maximize resilience and biodiversity on a landscape ecological scale. To meet the above goals, the methodology provides "recipes" that provide guidelines to create a seed mix, starting from a master list of all native grassland species in Minnesota that are commercially available, based on project site characteristics, context, goals, seed availability, and cost. The framework of the recipes allows users with no prior knowledge of native plants to easily design seed mixes very specifically tailored to their unique site, goals, and current state of the native grassland seed market.
