The silviculture Cited by: Foresters have used and adapted timber harvest regimes for decades to aid in the conservation and proliferation of wildlife, and a great deal of research has been conducted on the effects of timber harvest prescriptions on a wide variety of species (Sallabanks et al.Thompson et al.Semlitsch et al. ). Silviculture is often Cited by: 8. timber harvest documents (e.g. timber harvest plan) to identify potential impacts of proposed harvest activity on wildlife habitats.
In this study we used CWHR to model changes in species richness and habitat suitability resulting from woody biomass harvests in the Sierran mixed conifer forests of Shasta and Tehama counties. Results The Summary. Anthropogenic habitat degradation is a primary threat to global biodiversity. The overarching theme of my dissertation is one of conservation-based research for reducing the impacts of anthropogenic disturbances, specifically timber harvesting, on forest wildlife.
Summary Habitat effectiveness models are widely used by natural resource agencies to predict effects of management activities, especially timber harvest, on elk habitat. We evalu- ated such a model for elk in western Oregon and Washington by using expert opinion. Case Study: Harvesting Timber to Improve Wildlife Habitat. Jean and Marshall Brooks live in the Philadelphia suburbs but own 83 acres of woodland in Sullivan County.
While the Brookses aren't opposed to timber harvesting, they don't view their forest primarily as a source of timber. Opportunity costs of timber harvesting increased as the level of habitat conservation increased. However, changes in costs were not linear with the changes in the level of habitat protection. In the case of the northern flying squirrel, an opportunity cost to maintain breeding pair.
Benefits to wildlife habitat:Timber harvesting guidelines reduce the potential for timber harvesting activities to disturb sensitive sites, rare species, water features and unique habitats. Timber harvesting contributes to stream turbidity and affects salmonid habitat. The purpose of this study is to evaluate the effectiveness of best management practices.

benefits of a particular timber harvest. Timber harvesting and other forest management operations are affected by a broad suite of factors including, but not limited to, regulations, guidelines, professional judgements, landowner decisions, and weather-related conditions. Throughout this report, we use the expression forest. The DNR now has stand exam lists for all forested ecological sections, covering fiscal years – These lists represent a statewide year stand exam list, which is the DNR forest resource management spatial plan.
The year stand exam list was developed using a model based on the one created for the sustainable timber harvest analysis by Mason, Bruce, & Girard. negative effects on wildlife caused by development and other modifications of wildlife habitat. Conversion of naturally regenerated mature and old-growth forests to intensively managed plantations for timber production has raised concerns about habitat for. (relative) habitat suitability (MaxEnt) (Phillips et al.entire; Phillips and Dudikentire).
In addition to providing a map of relative habitat suitability, this process allowed us to evaluate an area’s suitability and determine whether the presence of the species was likely based on an assessment of known species-habitat.
We estimated the combined, cumulative effects of tree species succession, fire disturbance, fuel accumulation, fire hazard, wind disturbance and timber harvest on future species composition, age class distribution, timber products, and wildlife habitat suitability for. suppression and timber harvest. High fuel loads and connected canopies make the matrix among patches of evaluate habitat suitability (the likelihood of a spotted owl selecting an area for nesting based severity fire was allowed to burn and managed in order to restore wildlife habitat, promote healthy vegetation, and reduce fuels and the.
· Salvage logging in burned forests can negatively affect habitat for white-headed woodpeckers (Dryobates albolarvatus), a species of conservation concern, but also meets socioeconomic demands for timber and human safety.
Habitat suitability index (HSI) models can inform forest management activities to help meet habitat conservation objectives. types of activities, including timber harvest and post-harvest site preparation, and forest roads, as well as other land uses such as mining, grazing, or recreation.
A more site specific approach is needed to assess the sediment related effects of particular timber har-vest activities and to evaluate the effectiveness of spe. We present a habitat suitability index (HSI) model for black bears (Ursus americanus) living in the southern Appalachians that was developed a priori from the literature, then tested using location and home range data collected in the Pisgah Bear Sanctuary, North Carolina, over a year period.
The HSI was developed and initially tested using habitat and bear data collected over 2 years in. · The primary method of generating young aspen and re-establishment of high quality snowshoe hare habitat is via timber harvest of mature forest (Bates et al., ), so we simulated the effects of different harvest regimes on the probability of colonization and extinction within Sandhill using a 3 × 4 factorial design. We manipulated both size.

The National Forest Management Act (NFMA) of (P.L. ) is a United States federal law that is the primary statute governing the administration of national forests and was an amendment to the Forest and Rangeland Renewable Resources Planning Act ofwhich called for the management of renewable resources on national forest lands. The law was a response to lawsuits involving various. A reduction in habitat suitability from to of Silvio O.
Conte National Fish and Wildlife Refuge lands within WMU E1 was observed following a simulation in which all timber harvesting as a forest management practice was eliminated. Initial validation of this model for analyzing moose habitat at the WMU-scale is supported by correlation. Introduction. The effects of climatic change and anthropogenic disturbances, such as land‐use change, are negatively impacting biodiversity and altering ecological systems around the world (Stenseth et al.Walther et al.
).The increasing impacts of humans on natural ecosystems are leading to reductions in habitat area and quality for flora and fauna, which, in turn, lead to. · ABSTRACT Models of habitat suitability in postfire landscapes are needed by land managers to make timely decisions regarding postfire timber harvest and other management activities. Many species of cavity‐nesting birds are dependent on postfire landscapes for breeding and other aspects of their life history and are responsive to postfire management activities (e.g., timber harvest).
· Some modeling approaches use optimization to identify timber harvest and wildlife habitat targets (Bevers and Hof, ; Turner et al., ), while others simulate change produced by management activities (Gustafson, ). Optimization and simulation have inherent strengths and. the impact of timber harvest are difficult to make without specifying the characteristics of the natural system and the forest practice.

Understanding the cumulative effects of human activ- ities on wildlife habitats is important to wildlife manag- ers. Advances in spatial statistics, approaches to animal resource use, and geographic information systems have improved our ability to evaluate the effects of human activities on wildlife habitat suitability at large spatial. One potential result of timber harvest and regeneration minimize nonpoint source pollution, such as practices is a high level of human activity, including sedimentation and pollution of waterways caused by construction and frequent use of logging roads and timber harvest and other land use.
· Rabbit-habitat and timber harvesting. Janu. The Heald Tract Reservation in Wilton will have a timber harvest operation in the winter of that includes prescriptions to remove overstory trees to regenerate understory shrubs - specifically mountain laurel - that can greatly enhance cover for wildlife.
specifically. · Chestnut‐sided warbler habitat was stable at expected harvest levels but declined at lower harvest intensities, and yellow‐billed cuckoo habitat declined by 37% at expected harvest levels. Natural disturbance had little effect on habitat availability for any bird species compared to the effects of timber harvests and increasing forest age. Components of an effective wildlife management plan include 1) land management goals and objectives (by priority), 2) a resource inventory, 3) site specific habitat improvement recommendations, 4) a schedule for conducting management practices, and 5) record keeping and evaluation of management efforts and their impacts on wildlife habitat.
Forest resource planning processes in the western United States have been placing an increasing emphasis on wildlife and fish habitat goals. With this in mind, we developed a method that incorporates a Habitat Effectiveness Index (HEI) for Roosevelt elk (Cervus elaphus roosevelti) into the objective function of a mathematical forest planning model.
• Enhance the wildlife habitat in an area. • Remove mature timber, while protecting younger trees. • Enhance recreational values. • Remove dead and dying material. • Make a clearing for a home site. A professional forester or forest engineer can help identify and evaluate these objectives and plan alterna-tive means of reaching them.
· The Habitat Evaluation Procedure (HEP) is a habitat-based evaluation methodology developed by USFWS in for use as an analytical tool in impact assessments and project planning. HEP is a species-habitat analysis of the ecological value of a study area; its approach. Fuels-reduction treatments are commonly implemented in the western U.S. to reduce the risk of high-severity fire, but they may have negative short-term impacts on species associated with older forests.
Therefore, we modeled the effects of a completed fuels-reduction project on fire behavior and California Spotted Owl (Strix occidentalis occidentalis) habitat and demography in. WILDLIFE HABITAT EVALUATION PROCEDURE BACKGROUND Wildlife habitat models are a valuable tool for assessing the landscape for wildlife. Generally two types of models have been developed, either models for a particular species or models for the land use being considered such as cropland, forestland, or pastureland.
Consideration of the effects of. Following the initial timber harvest treatment, the site was aerial seeded with black spruce at 2 ounces per acre in the harvest area and in portions of the uncut area to the south (SC Figure 4).
Black spruce was selected as an additional regeneration species given its excellent suitability and natural regeneration potential in FPw An onsite. By linking wildlife habitat suitability models with habitat projection, an assessment of possible planning regimes, with both economic and ecological values, was established.
Forest Management Evaluation Criteria There are several financial models and criteria that can be used to evaluate alternative land use. The Habitat Evaluation Procedures (HEP) (Schamberger and Farmer ) were developed in response to the need to document the non-monetary value of fish and wildlife resources. HEP incorporates population and habitat theories for each species and is based on the assumption that habitat quality and quantity can be numerically described so that.
New Hampshire Wildlife Action Plan Biological Resource Use The ‘biological resource use’ category (IUCN 5) includes any “threat of consumptive use of wild biological resources including the effects of deliberate and unintentional harvesting; including the persecution or control of specific species” (Salafsky et al.
). · Wildlife habitat assessment is the evaluation of the relative habitat conditions available to a focal group of wildlife. Assessments of wildlife habitat are predicated on the basic assumption that at some level wildlife is controlled by its habitat, because an organism’s ability to survive depends in large part on the resources (e.g., food.
