We also experience
unprecedented weather, such as out-of-season heat waves, tornadoes and tropical
storms. These effects of climate change can transform our environments by
changing closely linked associations, such as the timing of hatching insects
with the arrival of migratory birds. It also changes the vegetation in an area
affecting the species that have evolved to depend on a specific plant
community. These changes can threaten many of the species we manage.
This is why the National Wildlife Refuge System is focused on trying to predict
changes to ecosystems so that action can be taken to help wildlife adjust.
You can also help! Small changes in our everyday lives can make a big
difference. Here are a few ways you can help our climate and support wildlife
conservation where you live.
