Welcome to the University of Vermont Extension Pollinator Program
The purpose of this effort is to support the adoption of farm practices that promote the well-being of pollinators, through education and applied research, in collaboration with other agencies, organizations. and people doing similar work.
Pollinators are essential to the production of many food crops. More than 100 U.S. grown crops rely on pollinators, which add an estimated $18 billion in crop production revenue. Pollinators also support healthy ecosystems needed for clean air, stable soils, and a diverse wildlife.
Both wild and domesticated pollinators are at risk. Honeybees are of concern nationwide, as the number of hives has decreased from 6 million in the 1940’s to about 2.5 million today. Wild pollinators such as some species of bumblebees are also in serious decline. The reasons for these declines include exposure to parasites and pesticides, loss of floral abundance and diversity due to changes in land use, and habitat destruction which limits nesting sites for wild pollinators.
The good news is that there are many well-described practices that farmers and other landowners can take to support pollinator health. This web site includes a collection of links to information that is relevant to pollinator health in agricultural settings in Vermont and the region.
The education and applied research provided by this program are primarily funded through grants and gifts, and we welcome your support.
"Do You Know Your 5?" Pollinator Support Factsheet Series (PSFS)
There are more than 350 species of wild bees in Vermont and each of the following factsheets spotlights the five bees which are most important to pollination of these fruits or vegetables. Each factsheet explains pollination factors, habitat, and species identification. By identifying and understanding the natural history of these bees, you can provide the specific habitat that will help to ensure resilient and abundant pollination, and the tasty treats that result from the bee/plant relationship.
