Book Description
Northern Arizona is home to at least 20 species of batsor two-thirds of the bat species found in the state (Cockburn 1960, Hinman and Snow 2003). Only a couple of these species live exclusively in ponderosa pine forests while the rest inhabit a variety of ecosystem types from desert scrub to pinyon-juniper to ponderosa pine-Gambel oak and mixed conifer (Arizona Game and Fish Department 1996, Hinman and Snow 2003). Bats are an important part of the forest ecology of northern Arizona because they prey on insects such as midges, moths, beetles, flies, mosquitoes, termites, and ants. They typically roost in the cavities of live trees and snags, under loose tree bark, in tree stumps and logs, in rock crevices, or in caves. As the new era of ecologically restoring forest ecosystems in the Southwest moves from experiments to full implementation, the question arises:What effects will restoration treatments have on forest wildlife, including often forgotten or poorly understood animal groups, such as bats? Thinning, for instance, might remove snags where bats roost, and burning could inadvertently destroy or alter such roosting sites.While its true that fire will create new snags, given the present forest conditions, they will be younger, smaller-diameter snags that are more susceptible to fire, and not the 27-inch-plus-diameter snags bats most often use. In this working paper, we look at research and studies that provide some recommendations about ways to maintain bat habitat while restoring forest tree health and vitality.

Book Description
A wildfire of variable severity swept through 717 acres (290 ha) of ponderosa pine forest in north-central Arizona in May 1972. Where the fire was intense it killed 90% of the small trees and 50% of the sawtimber, burned 2.6 in (6.5 cm) of forest floor to the mineral soil, and induced a water-repellent layer in the sandier soils. The reduced infiltration rates, which greatly increased water yield from severely burned areas during unusually heavy fall rains, caused soils to erode and removed some nutrients which had been mineralized by the fire. Water yields have declined each year toward prefire levels.

Book Description
Brings together the writings of practitioners and thinkers from a variety of fields--including forestry, biology, philosophy, ecology, political science, archaeology, botany, and geography--to synthesize what is known about ecological restoration in ponderosa pine forests and to consider the factors involved in developing and implementing a successful restoration effort.

Book Description
Until recently, forest managers have largely ignored the value of maintaining dynamic spatial patterns in forested ecosystems. In the America Southwest, where the norm in overstocked forests that are extremely susceptible to catastrophic fires and/or insect infestations and disease, restoring a spatial pattern of openings and tree groups would help alleviate these threats and move the forests within their historic range of variability. This ERI working paper focuses on restoring a dynamic spatial pattern to ponderosa pine forests in the American Southwest. It also addresses basic questions that land managers and others have about how to restore active spatial patterns across the forested Southwest.

Book Description
This book brings together scientific evidence and experience relevant to the practical conservation of bats. The authors worked with an international group of bat experts and conservationists to develop a global list of interventions that could benefit bats. For each intervention, the book summarises studies captured by the Conservation Evidence project, where that intervention has been tested and its effects on bats quantified. The result is a thorough guide to what is known, or not known, about the effectiveness of bat conservation actions throughout the world. Bat Conservation is the fifth in a series of Synopses that will cover different species groups and habitats, gradually building into a comprehensive summary of evidence on the effects of conservation interventions for all biodiversity throughout the world. By making evidence accessible in this way, we hope to enable a change in the practice of conservation, so it can become more evidence-based. We also aim to highlight where there are gaps in knowledge. Evidence from all around the world is included. If there appears to be a bias towards evidence from northern European or North American temperate environments, this reflects a current bias in the published research that is available to us. Conservation interventions are grouped primarily according to the relevant direct threats, as defined in the International Union for the Conservation of Nature (IUCN)’s Unified Classification of Direct Threats (www.iucnredlist.org/technical-documents/classification-schemes).
