Grow Wise Bee Smart | Best Management Practices (BMPs) for Bee Health in the Horticultural Industry

by Horticultural Research Institute, The AmericanHort Foundation

Acknowledgements. Best Management Practices (BMPs) for Bee Health in the Horticultural Industry was created by the Horticultural Research Institute. Development of this document would not have been possible without the cooperation and participation of numerous researchers and experts.

Mission. The mission of the Horticultural Research Institute is to direct, fund, promote and communicate horticultural research, which increases the quality and value of plants, improves the productivity and profitability of the horticulture industry, and protects and enhances the environment.

Introduction. Pollinators as a whole encompass a diverse population of thousands of different species, such as managed honey bees, wild bees, butterflies, birds, and bats. Protection of pollinators in general, especially bees, continues to be a major concern among the general public and within the green industry. Several culprits have been identified as factors contributing to managed honey bee losses, including Varroa mites, other pests/diseases of bees, loss of habitat and nutrition, and off-target effects of pesticides. Alternatively, wild, unmanaged bee populations are most greatly affected by landscape changes and habitat degradation.

California Invasive Species List

by California Invasive Species Advisory Committee (CISAC) to the Invasive Species Council of California (ISCC)
California Invasive Species List (cover)

The California Invasive Species Advisory Committee has created a list of invasive species that threaten California. This list includes species of all taxonomic types — vertebrate, invertebrate, plant and disease.

Summary. CISAC has created a list of invasive species that threaten California, as mandated by the ISCC Bylaws and the CISAC Charter. The list currently includes over 1,700 species of all taxonomic types— vertebrate, invertebrate, plant, and disease—and includes not only those damaging organisms already in the state but also those that could conceivably be introduced and become problems in the future. CISAC drew from over 80 existing lists from California and beyond, including regulatory lists and lists maintained by universities and NGOs. CISAC designed a website to collect input from area experts, and considers the list to be a living document that will be reviewed and updated continuously. Since March 2010 over 100 experts have created accounts on the website. CISAC developed a “scorecard” template for rating the impacts of a given species and our ability to respond to it, and has used it to assess over 200 species. This list forms the foundation for the strategic action plan CISAC will be developing.
