Environmental Assurance

Michigan Agriculture Environmental Assurance Program (MAEAP)

MAEAP'S Greenhouse System is based on an environmental risk assessment tool suited to the unique aspect of greenhouse production. Greenhouse*A*Syst is a single, integrated risk assessment that includes both the farmstead and cropping systems, and addresses the following environmental risk areas:

  • Site/soil evaluation
  • Water well condition and siting
  • Pesticide and fertilizer management
  • Petroleum product storage
  • Waste management
  • Irrigation management
  • Outdoor container management
  • Soil and water conservation practices


Some of the MAEAP-verified greenhouses include Twixwood Nursery, Romence Gardens, The Flower Farm, Matthes Farm, Avalon Farms, Sklarczyk Seed Farm, Sandy Ridge Farms, Sandy View Farm, Native Plant Nursery, Provenance Wildflower Farm, Sawyer Nursery, CBI's Giving Tree Farm, John Gernaat & Sons Greenhouses, Countryside Greenhouse, Greendoor Greenhouses, and Nash Greenhouse.
