This story seems to come up every year. Sadly, I find myself paying attention to it only after seeing my first monarchs last year in Shenandoah National Park. They are friendly and beautiful creatures.
Fortunately, there is a way to help:
In an attempt to counter two decades of destruction, the Fish and Wildlife Service launched a partnership with two private conservation groups, the National Wildlife Federation and the National Fish and Wildlife Foundation, to basically grow milkweed like crazy in the hopes of saving the monarchs.
Here is a website where you can order free milkweed seeds! I ordered mine moments ago and will be littering the edges of the field next to my house, where I saw a monarch flying last summer.
