Landscape Change

In partnership with the United States Fish and Wildlife Service, and other partners, scientists from USGS Fort Collins Science Center are working to create a suite of prioritization scenarios that will inform adaptive management for Gunnison sage-grouse.

Widespread anthropogenic development in the sagebrush steppe and shifting drought and wildfire patterns have contributed to the observed dramatic declines of the greater sage-grouse since the 1960s. Alteration of the sagebrush habitat can affect many aspects of the species life history, including survival and local resource use. Over many years, the combined effects of landscape composition on...

Many revegetation projects are intended to benefit focal wildlife species. Yet, few scope the ability of revegetation efforts to yield habitat. To investigate the ability of alternative sagebrush planting strategies to recover habitat conditions for wildlife like sage-grouse,  USGS and Colorado State University scientists developed a spatial vegetation-habitat recovery model. Scientists combined...

Arid shrublands of western North America face growing threats from disturbances such as wildfire, drought, and invasive species. These threats are increasingly altering the sagebrush ( Artemisia species) biome and degrading habitat for species of conservation concern such as greater sage-grouse ( Centrocercus urophasianus). Effective management and restoration are needed to slow or reverse these...

The use of rare plant habitat models in land management decisions can be constrained by issues surrounding data access, model quality, and institutional capacity, among other factors. This project seeks to understand challenges associated with using habitat models and explore avenues for addressing these challenges to facilitate greater use of habitat models in public lands decision making.

Biological soil crusts (biocrusts) are a community of living organisms, like moss, lichen, and algae, covering soils in arid and semi-arid ecosystems, providing important ecological functions like carbon cycling and soil stabilization. Analyses show that biocrusts are negatively associated with the abundance of invasive annual grasses that are responsible for increasing fire across the Great Basin...

Tree-ring science is a component of our interdisciplinary ecological research program that focuses on the effects of drought and human land use on forest ecology, fire ecology, and ecohydrology.

Below are ongoing or completed research projects related to forest ecosystems at the New Mexico Landscapes Field Station.

This project analyzes on-the-ground plant monitoring data across sagebrush and rangeland ecosystems to examine how fire, climate, topography, and plant communities influence the success of invasive annual grasses after fires.

Cheatgrass, an invasive annual grass, reduces ecosystem productivity, negatively impacts biodiversity, and is increasingly problematic in higher elevation ecosystems with climate change. Cheatgrass phenology (that is, the timing of yearly growth and lifespan) varies greatly with elevation, climate, and weather from year to year, which can make management planning difficult and reduce the ability...

Roads and their associated infrastructure can cause substantial and pervasive effects on adjacent ecosystems but are necessary for the movement and redistribution of goods, people, wealth, and natural resources in modern societies. The Fort Collins Science Center has initiated research looking at how roads and traffic may be impacting sagebrush ecosystems and the wildlife inhabiting them. This...
