Book Description
Even as they increase the beauty of our surroundings, trees provide us with a great many ecosystem services, incl. air quality improvement, energy conservation, stormwater interception, and carbon dioxide reduction. These benefits must be weighed against the costs of maintaining trees, including planting, pruning, irrigation, admin., pest control, liability, cleanup, and removal. This report presents benefits and costs for representative small, medium, and large trees in the Tropical region based on research carried out in Honolulu, Hawaii. Average annual net benefits increase with tree size and differ based on location:. Two hypothetical examples of planting projects are described to illustrate how the data in this guide can be adapted to local uses.

Book Description
Historical and prescribed fire regimes for different regions in the continental U.S. were compared and literature on season of prescribed burning synthesized. In regions and vegetation types where considerable differences in fuel consumption exist among burning seasons, the effects of prescribed fire season appears to be driven more by fire-intensity differences among seasons than by phenology or growth stage of organisms at the time of fire. Where fuel consumption differs little among burning seasons, the effect of phenology or growth stage of organisms is often more apparent, because it is not overwhelmed by fire-intensity differences. Species in ecosystems that evolved with fire appear to be resilient to one or few out-of-season prescribed burns. Illus.

Book Description
Fire events often have a large impact on recreation and tourism, yet these issues had not been addressed from a social science perspective. There are three distinct lines of research to address: examine values/attitudes and behaviors of recreation residence owners and year-round residents in the wildland-urban interface; examine recreationists¿ perceptions about fire suppression and postfire forest health issues; and examine perceptions and beliefs about recreation activities and impacts to fire-prone ecosystems in the wildland-urban interface. This report includes 17 of these studies grouped into four major topical headings: recreation use research, commun. research, program eval. and interface residents research, and trust research. Charts and tables.

Book Description
There has been widespread interest in applying new forest practices based on concepts presented in U.S. Forest Service General Technical Report PSW-GTR-220, "An Ecosystem Management Strategy for Sierran Mixed-Conifer Forests." This collection of papers (PSW-GTR-237) summarizes the state of the science in some topics relevant to this forest management approach, presents case studies of collaborative planning efforts and field implementation of these new practices, and clarifies some of the concepts presented in GTR 220. It also describes a method for assessing forest heterogeneity at the stand level using the Forest Vegetation Simulator and a new geographic information system tool for project-level planning that classifies a landscape into different topographic categories. While this collection of papers presents information and applications relevant to implementation, it does not offer standards and prescriptions. Forest management should be flexible to adapt to local forest conditions and stakeholder interests. This report does, however, strive to clarify concepts and present examples that may improve communication with stakeholders and help build common ground for collaborative forest management.
