Catkins are flowering at different times as climate changes – threatening their pollination and the wildlife that feed on them

Sven Batke, Edge Hill University

As temperatures and rainfall patterns change, the time that trees produce catkins could change and affect wildlife that rely on catkins for food.

Many beloved wildflowers bloom in early spring, while trees are still bare and the flowers have access to sunlight. Climate change is throwing trees and wildflowers out of sync.
