Ganey, Joseph L.; Bird, Benjamin J.; Baggett, Scott; Jenness, Jeffrey S., 2015. Density of large snags and logs in northern Arizona mixed-conifer and ponderosa pine forests
Old-growth ponderosa pine forests in Long Valley and Fort Valley Experimental Forests provide a window into historical spatial patterns of trees and non-forested openings.
Researchers are increasingly recognizing that ponderosa pine forests naturally occur in clumps of trees with isolated single trees in a matrix of non-forested openings.  Turns out that this spatial pattern is important in sustaining ecological processes such as fire spread, tree growth and regeneration, and creates biodiversity and wildlife habitat.  Yet, most past studies have examined spatial patterns on small plots, which underestimates the sizes of tree groups and openings.  
100 years ago a study was initiatied near the Fort Valley Experimental Forest in Arizona to look at how different varieties of ponderosa pines would grow in different forest/geographic areas. Researchers found that more northerly or higher elevation materials performed better.    
Northern goshawk nestlings
The elusive northern goshawk, its forest habitats, and the habitats of its bird and mammal prey are significant conservation issues related to the management of forests throughout the hawk’s North American range.  The Rocky Mountain Research Station has been enumerating the population size and documenting the population ecology and demography of individual goshawks on Arizona’s Kaibab Plateau for 20 years with the objective of identifying the vegetation composition and structure of forests habitats that best supports their survival and reproduction.
A clump of snags in ponderosa pine forest, northern Arizona.
Since 1997, RMRS scientists have monitored populations of snags (standing dead trees) and downed logs in northern Arizona mixed-conifer and ponderosa pine forests, as well as patterns of climate-mediated tree mortality influencing inputs to snag and log populations.
Forest management will protect genetic integrity of tree species only if their genetic diversity is understood and considered in decision-making. Genetic knowledge is particularly important for species such as ponderosa pine that are distributed across wide geographic distances and types of climates. Researchers revisit an assisted migration study in an Arizona ponderosa pine forest after 100 years to assess genetic diversity, adaptation patterns, and improve forest management of ponderosa pine.
Spruce beetle (Coleoptera: Curculionidae, Scolytinae) is the major disturbance agent of North American spruce, but current methods to suppress beetle populations vary in scale efficacy, cost, and environmental impact. A high-dose, high release MCH dispenser was found to be an effective area treatment for protection against spruce beetle attacks. Lethal trap trees and semiochemical repellents could provide managers with new tools for protecting hosts trees from spruce beetle attacks.
Snags (standing dead trees) and logs are important components of forest landscapes. RMRS scientists established a series of fixed plots in 1997 for monitoring snag populations. This research has direct ramifications for 11 national forests throughout the Southwestern Region, as well as for our overall understanding of the ecology of coarse woody debris and effects of climate change on forest structure and composition.
