Want Pollinators? Plant Trees
Thanks to widespread efforts to raise awareness of the large declines in bee and Monarch butterfly populations, most people are aware of the need to protect pollinators. Monarch butterfly populations have declined 90% in the last 20 years. Bees and other pollinators are in trouble too. Primary causes of the drastic declines in pollinator populations are thought to be habitat loss, invasive species, parasites, pesticides, and genetically engineered crops.
