Logging in the mountains of Mexico where monarchs overwinter also affects the species. Rob McCorkle wrote an article about the decline of the monarch population for the March issue of Texas Parks and Wildlife Magazine.

At their peak, a billion monarchs filled the skies; today that number is under 50-million. Yet, each of us along their migratory path can help them on their travels by doing one simple thing.

16ā€” The most significant thing scientists say you that you can do is plant milkweed, because that is the sole species the monarchs depend on to lay eggs for emerging caterpillars to feed on.
