The interaction between man and nature has always been a delicate balancing act. One prime example is the impact of tamarisk plants (salt cedar) along the Colorado River corridor. This invasive, non-native plant was originally introduced to the region as an ornamental and was later meant to create windbreaks and stabilize riverbanks. That might have been an inspired idea at the time, but the reality is that the tamarisk hoards light, water and nutrients. Along the Colorado River, the tamarisk has spread to such an extent that it has effectively altered the natural functions and processes of the ecosystem—and this negatively affects our water supply.
