Invasive Annual Grass (IAG) Spatial Dataset Compilation and Synthesis

USGS is working closely with partners in the Bureau of Land Management (BLM), U.S. Fish and Wildlife Service (USFWS), and the Intermountain West Joint Venture (IMJV) to collect and summarize spatial datasets that describe measurable aspects of invasive annual grasses (e.g., biomass or presence) across the western United Stated and beyond. The products developed through this project provide...

Developing Broad Scale Indicators for Monitoring Ecosystems and Landscapes

Many issues currently facing the Bureau of Land Management (BLM) and other large land managers span large landscapes, including sage-grouse conservation, wildfires, and energy development. Such challenges involve changes at both local and broad scales, but monitoring has typically focused at the scale of individual sites. The USGS is working to develop broad-scale indicators for monitoring...

Biology, Impacts and Control of Invasive Reptiles in the Everglades

Invasive species are considered to be second only to habitat degradation in terms of negative impacts on the Earth’s ecosystems, and our scientists make up a significant proportion of the global expertise in the rapidly-growing problem of invasive reptiles.

Species Distribution Modeling

A requirement for managing a species, be it a common native species, a species of conservation concern, or an invasive species, is having some information on its distribution and potential drivers of distribution. Branch scientists have been tackling the question of where these types of species are and where they might be in the future.
