Citizen scientists rush to catalog plant species on US-Mexico border

For all of May, people on both sides of the US-Mexico border are trying to document as many species of plants as possible. Naturalists have discovered that there are many species that are now hard to find in the United States, but healthy populations can be found across the border, and now wall, in Mexico. But tagging these species in Mexico can also be a challenge, in part because of risks from cartel activity. Host Carolyn Beeler talks with Sula Vanderplank, a field researcher for Next Generation Sonoran Desert Researchers, about the push to document species before it’s too late.
