Fund, the Plant Conservation Alliance, the U.S. Forest Service, and the Bureau of Land Management with oversight by the Pollinator Partnership™ (www.pollinator.org), in support of the North American Pollinator Protection Campaign (NAPPC–www.nappc.org). Lower Mississippi Riverine Forest Province 3 Why support pollinators? In theIr 1996 book, the Forgotten PollInators, Buchmann and Nabhan estimated that animal pollinators are needed for the reproduction “ Farming feeds of 90% of flowering plants and one third of human food crops. Each of us depends on these industrious pollinators in a practical way to provide us with the wide range of foods we eat. In addition, pollinators are part of the the world, and intricate web that supports the biological diversity in natural ecosystems that helps sustain our quality of life. Abundant and healthy populations of pollinators can improve fruit set we must remember and quality, and increase fruit size. In farming situations this increases production per acre. In the wild, biodiversity increases and wildlife food sources increase. that pollinators Asparagus, mustard greens, okra, and strawberries are some of the crops raised in the Lower Mississippi Riverine Forest that rely on honey bees and native bees for pollination. Domestic honey bees pollinate are a critical approximately $10 billion worth of crops in the U.S. each year. Unfortunately, the numbers of both native pollinators and domesticated link in our food bee populations are declining. They are threatened by habitat loss, disease, and the excessive and inappropriate use of pesticides. The loss of commercial bees to Colony Collapse Disorder (CCD) has highlighted how severe the issues of proper hive management are to reduce stresses caused systems.” by disease, pesticide use, insufficient nutrition, and transportation practices. -- Paul Growald, Currently, the pollination services that the commercial beekeeping industry provides are receiving much needed research and conservation resources. Co-Founder, The efforts to understand the threats to commercial bees should help us Pollinator partnership understand other pollinators and their roles in the environment as well. It is imperative that we take immediate steps to help pollinator populations thrive. The beauty of the situation is that by supporting pollinators’ need for habitat, we support our own needs for food and support diversity in the natural world. Thank you for taking time to consult this guide. By adding plants to your landscape that provide food and shelter for pollinators throughout their active seasons and by adopting pollinator friendly landscape practices, you can make a difference to both the pollinators and the people that rely on them.
