Ecology and space: A case study in mapping harmful invasive species Ecology and space: A case study in mapping harmful invasive species
The establishment and invasion of non-native plant species have the ability to alter the composition of native species and functioning of ecological systems with financial costs resulting from mitigation and loss of ecological services. Spatially documenting invasions has applications for management and theory, but the utility of maps is challenged by availability and uncertainty of data...

Topographic and fire weather controls of fire refugia in forested ecosystems of northwestern North America Topographic and fire weather controls of fire refugia in forested ecosystems of northwestern North America
Fire refugia, sometimes referred to as fire islands, shadows, skips, residuals, or fire remnants, are an important element of the burn mosaic, but we lack a quantitative framework that links observations of fire refugia from different environmental contexts. Here, we develop and test a conceptual model for how predictability of fire refugia varies according to topographic complexity and...

U.S. Geological Survey science for the Wyoming Landscape Conservation Initiative—2015 annual report U.S. Geological Survey science for the Wyoming Landscape Conservation Initiative—2015 annual report
This is the eighth annual report highlighting U.S. Geological Survey (USGS) science and decision-support activities conducted for the Wyoming Landscape Conservation Initiative (WLCI). The activities address specific management needs identified by WLCI partner agencies. In 2015, USGS scientists continued 24 WLCI projects in 5 categories: (1) acquiring and analyzing resource-condition data...

The climate space of fire regimes in north-western North America The climate space of fire regimes in north-western North America
Aim. Studies of fire activity along environmental gradients have been undertaken, but the results of such studies have yet to be integrated with fire-regime analysis. We characterize fire-regime components along climate gradients and a gradient of human influence. Location. We focus on a climatically diverse region of north-western North America extending from northern British Columbia...

U.S. Geological Survey science for the Wyoming Landscape Conservation Initiative—2014 annual report U.S. Geological Survey science for the Wyoming Landscape Conservation Initiative—2014 annual report
This is the seventh report produced by the U.S. Geological Survey (USGS) for the Wyoming Landscape Conservation Initiative (WLCI) to detail annual activities conducted by the USGS for addressing specific management needs identified by WLCI partners. In FY2014, there were 26 projects, including a new one that was completed, two others that were also completed, and several that entered new...

U.S. Geological Survey Science for the Wyoming Landscape Conservation Initiative: 2012 annual report U.S. Geological Survey Science for the Wyoming Landscape Conservation Initiative: 2012 annual report
Southwest Wyoming contains abundant energy resources, wildlife, habitat, open spaces, and outdoor recreational opportunities. Although energy exploration and development have been taking place in the region since the late 1800s, the pace of development for fossil fuels and renewable energy increased significantly in the early 2000s. This and the associated urban and exurban development...
