Monarch butterflies are vital pollinators that have been dying out due to a loss of habitat and harsh weather conditions. But families, clubs, and other volunteers can bring portions of the habitat back to life with nectar-rich plants like milkweed.
Scientists from several countries urged Mexican authorities to immediately halt logging in the Monarch Butterfly Biosphere Reserve and promote the regeneration of the forests that form its habitat, in a published letter in the current edition of the journal Science .
The California overwintering population has been reduced to less than 0.5% of its historical size, and has declined by 86% compared to 2017.

Some experts anticipate the butterfly’s fall migration currently underway to be the strongest since 2008.
