 Fish and Wildlife will chip in to plant milkweed seeds in refuges and other  areas it controls to create 200,000 acres of habitat along the Interstate 35 corridor from Texas to Minnesota, where 50 percent of monarchs migrate. Fish and Wildlife will encourage other federal and state agencies to do the same on public lands and is working with the governments of Mexico and Canada to help restore the iconic butterfly.
