Presenters: Mike Stoddard, Ecological Restoration Institute and Matt Tuten, USDA Forest ServiceDate: Thursday April 15, 2021 11am AZ/12pm MDT This webinar will share research on forest structure and understory vegetation responses to three restoration treatments (thin/burn, burn, and control) over 10 years on a mixed-conifer site in southwestern Colorado. Forest density, canopy cover, and crown …

Oct 16, 2019: Contributions of fire refugia to resilient ponderosa pine and dry mixed-conifer forest landscapes

by swfscEvents, Webinars September 15, 2019March 9, 2024No Comments

Presenter: Jonathan Coop, Western Colorado University Date: October 16, 2019 11am AZ/12pm MDT In western North America, ponderosa pine and dry mixed-conifer forest types appear increasingly vulnerable to wildfire-catalyzed conversion to alternate and non-forest vegetation types. However, unburned or only lightly impacted forest stands that persist within burn mosaics—termed fire refugia—may sustain a range critical …

Fire Regime Reconstruction Methods

by swfscScience Synthesis November 1, 2014October 21, 2024No Comments

This working paper discusses several methods for reconstructing historical fire regimes.Each of these methods will be discussed in terms of advantages, disadvantages, inherent uncertainties, and assumptions as well as temporal and spatial precision. The potential value and limitations for reconstructing historical forest structure and composition with each method are also briefly covered. Working Paper 32, …

June 11, 2014: People, fire, and insects: Three centuries of disturbance interactions along an ecological gradient of the Pinaleño Mountains, Arizona

by swfscEvents, Webinars June 16, 2014May 17, 2023Comments are Disabled

Presenter: Kit O’Connor, University of Arizona In the Pinaleño Mountains of Southeast Arizona, a series of high-severity insect outbreaks and fires in recent decades appear to be unprecedented in the historical record. These disturbances raise concerns about forest resilience and long-term sustainability of one of the most ecologically diverse landscapes in the southwest. We used …

February 2014: Fostering resilience in Southwestern ecosystems: A problem solving workshop

by swfscEvents, Workshops April 27, 2014April 5, 2024Comments are Disabled

Fostering resilience in Southwestern ecosystems: A problem solving workshop Ecosystems and fire regimes are moving into new domains as a consequence of climate change, disturbance, and other causes. Fire professionals and land managers in the region are confronted with new fire regimes, fire effects, and ecosystem recovery trajectories following disturbance. To help fire and ecosystem …

Fuel Treatment Longevity

by swfscScience Synthesis October 1, 2013October 21, 2024No Comments

There are several ways to evaluate fuel treatment effectiveness: observations, case studies, mathematical models, and empirical studies. Within these four categories, there are several methods that can be used to evaluate the effectiveness of fuel treatments both immediately after treatment and over time. This paper summarizes the goals, effects, and advantages of various treatment actions; …

SW Mixed Conifer Forests: Evaluating Reference Conditions to Guide Fuel Treatments

by swfscScience Synthesis October 1, 2013October 21, 2024No Comments

This working paper covers three topics to guide treatments in mixed-conifer forests of the Southwest: 1) describes the current knowledge of mixed-conifer historical reference conditions for fire regimes, stand structure, and species composition in the Southwest (Arizona, New Mexico and adjacent areas); 2) provides field diagnostics to assess reference conditions; and 3) offers land managers …
