For over 30 years we have monitored the ecosystem dynamics of the mesas and mountains of northern New Mexico, co-located with mangers. We use a place-based science approach, defined as “science that is founded on long-term, repeated, field data and observations, as well as traditional knowledges, and regularly engages local managers and community members.” This approach enables us to provide land...

This project involves development of tools for the detection and control of invasive reptiles in Florida, with an emphasis on pythons and tegu lizards. The goals are to reduce the risk of reptile invasions, investigate early detection methods, maintain rapid response capacity, and understand invasive reptile population biology and ecology to inform management options.

Little is known about the role of fire in the sagebrush ecosystem within the range of the Gunnison sage-grouse ( Centrocercus minimus), and fire has been mostly absent from these systems in the 20th century, partially owing to active fire suppression.

The Wyoming Landscape Conservation Initiative (WLCI) addresses effects of land-use and habitat changes on Southwest Wyoming’s natural resources. In partnership with twelve Federal, State, and local natural resource agencies, and non-governmental organizations– FORT and ten other USGS centers are conducting dozens of integrated science projects to assess the status of Southwest Wyoming’s natural...

Western Mountain Initiative (WMI) is a long-term collaboration between FORT, WERC, NOROCK, USFS, NPS, LANL, and universities worldwide to address changes in montane forests and watersheds due to climate change. Current emphases include altered forest disturbance regimes (fire, die-off, insect outbreaks) and hydrology; interactions between plants, water, snow, nutrient cycles, and climate; and...

Episodic droughts have long been known to trigger accelerated tree mortality in forests worldwide, including in the Southwest U.S. Scientific understanding of the process drivers and spatial patterns of tree mortality is surprisingly limited, constraining our ability to model forest responses to projected increases in drought. The onset of regional drought since the late 1990s has resulted in...

High-severity crown fires in Southwestern dry-conifer forests — resulting from fire suppression, fuel buildups, and drought — are creating large treeless areas that are historically unprecedented in size. These recent stand-replacing fires have reset extensive portions of Southwest forest landscapes, fostering post-fire successional vegetation that can alter ecological recovery trajectories away...

Mountain ecosystems of the western U.S. provide irreplaceable goods and services such as water, wood, biodiversity, and recreational opportunities, but their potential responses to projected climatic patterns are poorly understood. The overarching objective of the Western Mountain Initiative (WMI) is to understand and predict the responses—emphasizing sensitivities, thresholds, resistance, and...
