How does habitat loss specifically affect pollinators?

Habitat loss harms pollinators by removing food sources and nesting sites they depend on. When forests, grasslands, and meadows are cleared for farming or urban development, native flowers disappear, reducing nectar and pollen availability. Bees, butterflies, and birds must travel farther to find food, wasting energy and reducing reproductive success. Fragmented landscapes also isolate populations, making pollinators more vulnerable to predators and pesticides. Loss of diverse plant species leads to less stable ecosystems because pollinators and plants depend on each other for survival. For example, wild bees often specialize on certain flowers—if those plants vanish, the bees die out too. This decline directly affects crops such as fruits, nuts, and vegetables that require pollination. Globally, scientists report over 40 percent of insect pollinators are in decline, mainly due to habitat loss. Creating wildflower corridors and reducing pesticide use are proven ways to help pollinators recover and keep ecosystems productive.
