Predicting snow water equivalence (SWE) and soil moisture response to restoration treatments in headwater ponderosa pine forests of the Desert LCC
Critical Management Question 1: Water Management and Climate Change
How are climate change, water management, and their interaction affecting the physical processes that support springs, aquatic and riparian habitats, species, and human cultures? What are viable management options to mitigate these effects and support ecosystem functions? How can climate change, hydrological, ecological, and/or biological models be used to better understand the potential future effects of climate change, inform adaptive management and development of beneficial management practices, and create related decision support tools?
Critical Management Question 2: Monitoring Species/Processes and Related Threats/Stressors
What species and ecological processes are sensitive to climate change and/or other large scale stressors (e.g., water management, invasive species, altered fire regime, wind erosion) and can be effectively monitored to indicate the overall effects of these stressors on ecosystems, habitats, and species, thus helping managers detect, understand, and respond to these changes? What are the best monitoring designs and protocols to detect changes to these processes and species at temporal and geographic scales suitable for providing adequate and reliable metrics?
Critical Management Question 5: Changing Wildfire Regimes and Riparian Habitat Management
Under what conditions or circumstances are changes in wildfire regimes (e.g., frequency, size, and severity), influenced by climate change, land use practices, and invasive species, likely to have significant impacts on the biodiversity and ecosystem function and services of riparian ecosystems? What management practices might be most effective for addressing changing wildfire regimes in riparian systems?
Grantee: Northern Arizona University
Principle Investigators: Frances O'Donnell
Cooperative Agreement: $153,109 in non-Federal funds and $149,866 in Federal funds provided by Bureau of Reclamation
Project Duration: 2013-2015
The goal of this project is to combine remotely sensed data, field measurements, and geospatial statistics to model snow water equivalence and soil moisture response to ponderosa pine forest restoration treatments at existing already-treated research sites in the Verde River basin of northern Arizona and to identify those treatments that are optimal from a water-balance perspective for sustaining water availability for plants as well as downstream water users in Verde Valley and the Phoenix metropolitan area.
Brief Project Description
Northern Arizona University will build upon the U.S. Forest Service Four Forest Restoration Initiative in Northern Arizona to investigate how restoration efforts can affect the water volume available in the snowpack and soil moisture in the Desert LCC. This project will result in a tool that can be used to predict the water volume in snowpack and soil moisture response to various forest treatments.
