Document Summary
Animals are necessary for 75% of all crops. Pollination is an ecosystem service that is supporting/provisioning service. 90% all flowering plants pollinated by animals o. Staple crops like rice and wheat and grasses are wind pollinated o. What are the reasons for pollinator decline? o o. Less biodiversity of plants and species of plants that depend on them. Climate change- bees ned hives at specific temp. Invasive pollinators can displace pollinators or invasive plants can displace host plants. Spread of pests and pathogens that carry viruses and can infect bees o o. How can limit pollinator decline? o o o. A lot of historical pollinators may be gone, pollinating different plants than used to, loss of. Put more flowering plants in crop fields so they can have something to pollinate. Some way to manage diseases or treat them. Ban use of some pesticides habitat could shift these interactions. Loss of bee species= loss of redundancy (multiple species pollinating same plant)
