The US Geological Survey (USGS), working with the partners in the watershed, compiled mercury data for freshwater fishes to understand how mercury concentrations, and risk to consumers, varies across the watershed.

The Dragonfly Mercury Project—Story Map

Dragonflies were sampled from 100 U.S. national parks, including very remote areas.

Statistical Tools for Wind and Solar Energy Development and Operations

Solar and wind power development is increasing exponentially in the United States. However, these energy sources may affect wildlife, either directly from collisions with the turbine blades or photovoltaic arrays or indirectly from loss of habitat and migration routes. An important component to understanding the effects of these renewable energy projects on wildlife is accurate and precise estimates of fatality.

Land Treatment Exploration Tool

The Land Treatment Exploration Tool is designed for resource managers to use when planning land treatments. The tool provides useful summaries of environmental characteristics of planned treatment areas and facilitates adaptive management practices by comparing those characteristics to other similar treatments within a specified distance or area of interest.  Provisional Software.

Land Treatment Digital Library (LTDL)

The Land Treatment Digital Library (LTDL) was created by the USGS to catalog legacy land treatment information on Bureau of Land Management lands in the western United States. The LTDL can be used by federal managers and scientists for compiling information for data-calls, producing maps, generating reports, and conducting analyses at varying spatial and temporal scales.

Data Entry Module for the Land Treatment Digital Library (LTDL)

This software allows agencies, organizations, and individuals to download an empty, stand-alone Land Treatment Digital Library database to individual or networked computers. Data entered in these databases may be submitted to the USGS for possible inclusion in the online Land Treatment Digital Library (
