Introduction: Senses of place in the face of global challenges

Publications Posted on: March 12, 2022
It is now well established that humans are the most powerful influence on the environment. The scale, pace and intensity of human activity is fundamentally altering earth’s climate system (IPCC, 2014) and driving global biodiversity and ecosystem decline (IPBES, 2019).

Baseflow recession analysis in the inland Pacific Northwest of the United States

Publications Posted on: March 12, 2022
The storage-discharge relationships of 26 watersheds in the inland Pacific Northwest of the United States were analyzed. Four fitting methods were used to obtain the baseflow coefficients: lower envelope, organic correlation, and ordinary and inverse least squares. Several climatic and terrain attributes were evaluated as predictors of baseflow coefficients.

Climate-driven, but dynamic and complex? A reconciliation of competing hypotheses for species’ distributions

Publications Posted on: December 15, 2021
Estimates of the percentage of species "committed to extinction” by climate change range from 15% to 37%. The question is whether factors other than climate need to be included in models predicting species’ range change. We created demographic range models that include climate vs. climate-plus- competition, evaluating their influence on the geographic distribution of Pinus edulis, a pine endemic to the semiarid southwestern U.S.

Fire ecology and management of southwestern forests [Chapter 11]

Publications Posted on: December 07, 2021
Forests in the southwestern USA are well adapted to dry conditions. High lightning incidence, long human habitation, and frequently windy conditions make the Southwest stand out for a high pace of burning. Forests are structured by climatic gradients created by elevation and topography. Low-elevation woodlands experience the driest conditions, but low productivity limits fuels.

Protected-area targets could be undermined by climate change-driven shifts in ecoregions and biomes

Publications Posted on: October 01, 2021
Expanding the global protected area network is critical for addressing biodiversity declines and the climate crisis. However, how climate change will affect ecosystem representation within the protected area network remains unclear.

Wind-bounded grasslands of North America

Publications Posted on: September 13, 2021
Climate may separate grasslands from surrounding forests and shrublands, but an alternative option is that grasslands are suitable for trees except in the presence of frequent fires, which are spread great distances by strong winds.

The Coweeta Hydrologic Laboratory and the Coweeta LTER Project

Publications Posted on: July 13, 2021
The Coweeta Hydrologic Laboratory (CHL) is a USDA Forest Service (FS) Experimental Forest, located in western North Carolina, in the southern Appalachian Mountains. Established in 1934, CHL has long-term data records that include climate, streamflow, stream and atmospheric chemistry, and vegetation in several small, experimentally-manipulated and reference watersheds.

Harbingers of Change: Arizona Sky Islands Offer Unique Opportunities to Understand Climate Change, Carbon, Fire, and Ecological Transition

Documents and Media Posted on: June 23, 2021
Just north of the United States–Mexico border, the Huachuca Mountains of Arizona are situated near the center of the Madrean Sky Island archipelago. This ecosystem is incredibly biodiverse. Vegetation transitions are shaped by gradients of elevation and aspect; grasslands cover the base of slopes while the peaks are topped with stands of pure aspen, ponderosa pine, and mixed conifer forests. These unique islands provide scientists the opportunity to study ecology, fire, and climate change in isolated areas. Document Type: Other Documents

Rocky Mountain Research Station scientists recommend approach to adapt wildland management to uncertainty

FS News Posted on: May 24, 2021
MISSOULA, Mont., May 24, 2021 — Scientists from the Rocky Mountain Research Station collaborated to explore how research and management can confront increasing uncertainty due to climate change, invasive species, and land use conversion.

Contemporary fire regimes provide a critical perspective on restoration needs in the Mexico-United States borderlands

Publications Posted on: March 27, 2021
The relationship between people and wildfire has always been paradoxical: fire is an essential ecological process and management tool, but can also be detrimental to life and property. Consequently, fire regimes have been modified throughout history through both intentional burning to promote benefits and active suppression to reduce risks.
