Harbingers of change in the Arizona Sky Islands

Science Spotlights Posted on: March 16, 2021
Fuel treatments can help moderate fire behavior and reduce competition for water, but it is not yet established whether these treatments will be enough to yield resilient ecosystems in the face of a changing climate. This study examined the potential for prescribed fuel treatments and restoration of historical fire frequencies to mitigate the effects of climate change on forest species distributions, composition, biomass, and fire severity in Arizona’s Sky Islands.

The “living map” of Mexican spotted owl habitat

Projects Posted on: January 13, 2021
Researchers and managers have partnered to create cutting-edge, high-resolution, high-accuracy maps of Mexican spotted owl habitat - as well as long-term habitat trends - that can be updated annually as new data become available. An interactive Google Earth Engine experimental app allows end-users to explore mapped products.

FireCLIME VA: A New Fire and Climate Vulnerability Assessment Tool for the U.S. Southwest

Documents and Media Posted on: December 08, 2020
The FireCLIME VA tool is a new resource that allows land managers to compare management strategies under various climate scenarios and to gauge the potential effectiveness of those strategies for reducing undesirable impacts of climate on wildfire regimes and resulting impacts of wildfire on natural ecosystems.  Document Type: Other Documents

Habitat and growth of ponderosa pine seedlings 11-16 years after fire

Science Spotlights Posted on: November 02, 2020
Ponderosa pine seedling establishment can be constrained following especially large, high-severity wildfires. Young seedlings face high mortality levels in the first few years and remain vulnerable to the next fire until they are taller. Understanding attributes associated with the growth of naturally regenerating seedlings that survive 10+ years postfire is useful in developing post-fire management strategies.
