Examining post-fire vegetation recovery with Landsat time series analysis in three western North American forest types

Publications Posted on: May 30, 2019
Background: Few studies have examined post-fire vegetation recovery in temperate forest ecosystems with Landsat time series analysis. We analyzed time series of Normalized Burn Ratio (NBR) derived from LandTrendr spectral-temporal segmentation fitting to examine post-fire NBR recovery for several wildfires that occurred in three different coniferous forest types in western North America during the years 2000 to 2007.

Is increased precipitation during the 20th century statistically or ecologically significant in the eastern US?

Publications Posted on: September 26, 2018
We address the climate versus disturbance debate to understand drivers of change in human-environment systems. We examine whether recent increased precipitation episodes (‘pluvials’) are unique and have ecological implications for the humid climate of the eastern United States. Robust statistical analyzes presented here indicate that the 20th century was wet, but not significantly different than other centuries during the last millennium.

Next Generation Fire Severity Mapping

Tools Posted on: July 06, 2018
The Next Generation Fire Severity Mapping is a tool designed to depict the probability of high-severity fire, if a fire were to occur, for several ecoregions in the contiguous western U.S. Statistical models were used to generate “wall-to-wall” maps for 13 of the 19 ecoregions. 

High-severity fire: Evaluating its key drivers and mapping its probability across western US forests

Publications Posted on: April 23, 2018
Wildland fire is a critical process in forests of the western United States (US). Variation in fire behavior, which is heavily influenced by fuel loading, terrain, weather, and vegetation type, leads to heterogeneity in fire severity across landscapes. The relative influence of these factors in driving fire severity, however, is poorly understood.

Delineating climate refugia for native aquatic species with big crowd-sourced databases

Publications Posted on: April 12, 2018
Topographic diversity is the essence of mountain environments in western North America, a diversity that manifests itself hydrologically in a host of forms - rivers, streams, lakes, wetlands, and springs - that constitute habitats for a wealth of fish, amphibians, mussels, and insects.

The future of subalpine forests in the Southern Rocky Mountains: Trajectories for Pinus aristata genetic lineages

Publications Posted on: April 03, 2018
Like many other high elevation alpine tree species, Rocky Mountain bristlecone pine (Pinus aristata Engelm.) may be particularly vulnerable to climate change. To evaluate its potential vulnerability to shifts in climate, we defined the suitable climate space for each of four genetic lineages of bristlecone pine and for other subalpine tree species in close proximity to bristlecone pine forests.

Data Descriptor: TerraClimate, a high-resolution global dataset of monthly climate and climatic water balance from 1958-2015

Publications Posted on: March 27, 2018
We present TerraClimate, a dataset of high-spatial resolution (1/24°, ~4-km) monthly climate and climatic water balance for global terrestrial surfaces from 1958–2015.

Coram Experimental Forest daily meteorology data for Desert Ridge and Terrace Hills weather stations: 1996-2015

Datasets Posted on: March 15, 2018
This data publication contains daily meteorological data collected at the Desert Ridge and Terrace Hills weather stations located on the Coram Experimental Forest (Flathead National Forest) in Montana. The Terrace Hills weather station was installed in May of 1996, and the Desert Ridge weather station was installed in May of 2001. Data are included up through 2015 for both stations.

Uneven-aged management on Fort Valley Experimental Forest

Projects Posted on: October 17, 2017
This project continues research that began in 1925, measuring trees within a study block that has used even and uneven-aged management techniques, to determine the growth and how climate variables may have impacted this. Previously-measured trees were remeasured in 2017, and tree data will be correlated with long-term weather data at FVEF. Measurements will continue to be taken into 2018.
