Lake Mead Exotic Plant Management Team

Exotic invasive plants are a widespread problem that almost everyone is familiar with. The weeds in your backyard that you pull every weekend are an example. Within the National Park System alone, there are over 2.6 million acres infested with these non-native, invasive plants. They cause numerous problems. They destroy cultural and historical sites, increase fire hazards, deplete natural resources such as water, and they crowd out native vegetation.

Exotic Plant Management Team

In 2000, spurred by the Congressional Natural Resource Challenge, the National Park Service acted on a national level in response to the growing invasive plant problem and created the first Exotic Plant Management Teams (EPMTs). Today there are 16 teams that are deployed across the entire country including Hawaii, Alaska & the US Virgin Islands.

The Lake Mead EPMT served as a model for the development of the nationwide EPMT program from 1996 to 2000. Permanent NPS funding was secured for the team in 2002. The team has leveraged this funding by creating partnerships with several federal, state and local partners. After all, these plants know no boundaries. The EPMT has also partnered with the United States Geological Survey to conduct weed control studies to improve effectiveness.

Due to its numerous years in operation and effective control methods, the Lake Mead NRA EPMT is widely regarded as one of the best invasive weed control groups in the region. Because of this, the team is often solicited by other federal land management agencies, local governments and other entities.
