The U.S. is running short of people who can tell the forest from the trees.
Organizations such as the National Park Service and Bureau of Land Management can’t find enough scientists to deal with invasive plants, wildfire reforestation and basic land-management issues.
Botanists use the term “plant blindness” to describe the growing inability by Americans—and even well-degreed biologists—to tell the difference among even basic plants.
