In their rapid colonization of soil exposed by fires, floods, and
grazing animals, weeds resemble the human specialists we label
Emergency Medical Technicians (EMTs). Weeds are the first
responders when disasters occur in nature. They occupy bare soil
and prevent erosion by wind and water. In extreme cases such as a
landslide, weeds are essential to the healing processes that
replace the lost soil. Like a Band-Aid on a skinned knee, weeds
protect the land while it recovers. Besides protecting the soil
after disaster, weeds provide food for wildlife, and some of them
provide food and medicine for people. Able to withstand harsh
conditions, weeds will proliferate as global warming and other
human impacts intensify. Thus, nature's EMTs will increase while
all other plants decline. The book provides a succinct definition
of weeds according to their form and function in ecosystem
processes. The narrative uses a representative set of weed species
from a desert location to illustrate the full range of weed
characteristics.
