Detecting spawning of threatened chum salmon Oncorhynchus keta over a large spatial extent using eDNA sampling: Opportunities and considerations for monitoring recovery

Publications Posted on: December 11, 2020
Over the last century, anthropogenic activities have caused substantial declines in the abundance of chum salmon (Oncorhynchus keta) throughout their range in western North America. As a result, chum salmon were listed as threatened under the U.S. Endangered Species Act in 1999. Recovery strategies have been developed, but limited baseline data on distribution impedes implementation of these strategies.

Quantifying ecological resilience at landscape scales

Science Spotlights Posted on: December 09, 2020
Ecological resilience has previously been explored mostly as a theoretical concept. To put it into practice, managers need methods to quantify the ecological resilience of current conditions and project resilience under future scenarios. This paper offers a process for using geospatial data, simulation modeling, and landscape pattern analysis to evaluate ecosystem resilience at management scales.

Evaluating post-wildfire logging-slash cover treatment to reduce hillslope erosion after salvage logging using ground measurements and remote sensing

Publications Posted on: November 06, 2020
Continuing long and extensive wildfire seasons in the Western US emphasize the need for better understanding of wildfire impacts including post-fire management scenarios. Advancements in our understanding of post-fire hillslope erosion and watershed response such as flooding, sediment yield, and debris flows have recently received considerable attention.

The fundamentals of belowground bud banks

Science Spotlights Posted on: August 28, 2020
Similar to a seed bank, buds can be stored in the soil over time to form a bud bank. These belowground bud banks are the primary source of seasonal regrowth in most plant communities and are crucial to plant community recovery following disturbance. We summarized the current knowledge of belowground bud banks and their role in maintaining plant population, community, and ecosystem function following disturbance and during climatic variability. 

Metrics and models for quantifying ecological resilience at landscape scales

Publications Posted on: August 13, 2020
An explicit link between the abiotic environment, the biotic components of ecosystems, and resilience to disturbance across multiple scales is needed to operationalize the concept of ecological resilience. To accomplish this, managers must be able to measure the ecological resilience of current conditions and project resilience under future scenarios of landscape change.

Proceedings of the Fire Continuum-Preparing for the future of wildland fire; 2018 May 21-24; Missoula, MT

Publications Posted on: July 22, 2020
The Fire Continuum Conference, co-sponsored by the Association for Fire Ecology and the International Association of Wildland Fire, was designed to cover both the biophysical and human dimensions aspects of fire along the fire continuum. This proceedings includes many of topics covered during the conference - including pre-fire planning and management, strategies during an incident, and post-fire effects and management options.

Wood wastes and residues generated along the Colorado Front Range as a potential fuel source

Publications Posted on: June 22, 2020
Throughout the United States there is interest in utilizing renewable fuel sources as an alternative to coal and nat-ural gas. This project was initiated to determine the availability of wood wastes and residues for use as fuel in ce-ment kilns and power plants located along the Colorado Front Range.

Implications of reduced stand density on tree growth and drought susceptibility: A study of three species under varying climate

Publications Posted on: June 20, 2020
A higher frequency of increasingly severe droughts highlights the need for short-term measures to adapt existing forests to climate change. The maintenance of reduced stand densities has been proposed as a promising silvicultural tool for mitigating drought stress. However, the relationship between stand density and tree drought susceptibility remains poorly understood, especially across ecological gradients.

Quantifying long-term post-fire sediment delivery and erosion mitigation effectiveness

Publications Posted on: April 02, 2020
Large wildfires can have profound and lasting impacts not only from direct consumption of vegetation but also longerterm effects such as persistent soil erosion. The 2002 Hayman Fire burned in one of the watersheds supplying water to the Denver metropolitan area; thus there was concern regarding hillslope erosion and sedimentation in the reservoirs.

Natural recovery from cropland

Publications Posted on: February 19, 2020
Man has been a chief factor disturbing the natural forces, which maintain the plant cover of the earth's surface. He has cut down or burned much of the virgin timber and broken the sod of prairies and plains in his struggle for food, clothing, and shelter. Early settlers of the front range of the Colorado Rockies turned to cultivated crops to increase the food supply.
