Vegetation Monitoring
Executive Summary
- The Weed Sentry program surveyed more than 750 miles of federal lands in Clark County for invasive, exotic plant species.
- Weed Sentry also removed more than 600,000 individual invasive plants from federal
lands. These removals represent pro-active efforts that may have forestalled large
infestations difficult and costly to eradicate. - In response to a request by the manager of the Fish and Wildlife Service Desert National
Wildlife Refuge, a major effort of surveying springs for plant community composition
and invasive plants provided unique knowledge services by the Weed Sentry program.
No such baseline information existed for the Sheep Range. …

Vegetation Monitoring
Executive Summary
- Weed Sentry staff surveyed for exotic species on 208 miles of roads on NPS land and on 61 miles of BLM land. Due to sparse precipitation this winter, exotic species are much less abundant this year compared to last year at this time.
- Other exotic species projects initiated this quarter included an assessment of invasion patterns below native shrubs for early detection of potential invasion “hotspots,” and a community invasibility experiment established near the NPS nursery with substantial involvement from NPS ATR Ms. Alice Newton.
- A manuscript detailing several experiments with the invasive species Sahara mustard was submitted …
