This book was released on 2017 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: Road crossings have significant effects on wildlife, but there is limited information on how road crossings affect stream-associated salamanders. Stream-associated salamanders are vital to their ecological communities and are likely to experience the effect of roads more readily than other species due to their physiological characteristics. To test the effects of road crossings on stream-associated salamanders, I surveyed 12 pairs of confluent streams – one stream crossed by a road and the other not in each pair – within Holly Springs National Forest, Mississippi. Surveys in the summer of 2015 were used to measure abundance and species richness of stream-associated salamanders. Transects were established across streams and abundance and species richness were measured at different distances from the road crossing (or stream midpoint where no road was present). Although salamanders were not abundant and only about 40% of samples contained any salamanders, abundance and richness varied between road-free and road-crossed streams, having 2.5 times as many individuals and 2.4 as many species per transect in road-free streams. The effect on abundance associated with roads was greater than previously found in Appalachia where salamanders are more abundant and species rich. There was no significant difference in abundance or species richness with distance (0–36 m) from the road crossing, but greater statistical power was needed to detect significance for the small effect size observed. Road-free and road-crossed sampling locations varied from 300–2500 m apart and no relationship existed for distance between and difference in abundance or species richness for paired locations. This lead to the conclusion that the extent of the road-effect zone lies between 36 and 300 m. When the data were re-analyzed without including the least stream-associated species (Plethodon mississippi), the results were essentially the same. There was a significant period × position interaction effect, suggesting that the first effort might have affected salamander abundance in the late summer sampling. Abundance and species richness were not associated with microclimate factors that differed between road-free and road-crossed streams. Considering the difference in magnitude for road-effects between this and Ward et al. (2008), characteristically similar disturbances in different regions may vary in their magnitude and extent – this could help explain the effect of sampling disturbance and no association between microclimate factors and salamander abundance and species richness. Additional sampling in other seasons and surveys that include additional, further from the road or midpoint might help to resolve uncertainty about spatial and temporal variation. Future research might also include components of salamander movement using mark-recapture techniques, since there are some suggestions that there are substantial temporal changes in location of the salamanders in this community.

Book excerpt: This volume presents 5-year results of silvicultural treatments associated with ecosystem management research in the Ouachita Mountains of Arkansas. Results from stand-level treatments include regeneration dynamics of pine and hardwood species, effects of treatment on birds and small mammals, mast production, visual quality, oak decline, and organic matter. Pretreatment landscape findings include measurements of woody vegetation; birds, mammals, and herpetofauna; fish communities and trophic structure; hydrology; and evaluation of susceptibility to gypsy moth outbreaks.

This book was released on 2002 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental impacts associated with the degradation of off-highway vehicle (OHV) trails have become a serious concern in many regions. Where OHV trails indiscriminately cross alpine areas, wetlands, steep slopes, and other areas with sensitive soil conditions, trails can become rutted, mucky, and eroded. Such areas are referred to as degraded trail segments. Degraded trails develop when trail use exceeds the trail's natural carrying capacity. This document provides land managers and trail users with an introduction to OHV trail degradation and outlines a framework for management responses.

Download or read book Canada s Report on the Montr al Process Criteria and Indicators for the Conservation and Sustainable Management of Temperate and Boreal Forests written by Canadian Forest Service and published by . This book was released on 1997 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Montreal Process was formed to advance the development of internationally agreed-upon criteria & indicators for sustainable forest management. The Canadian commitment to this process is demonstrated by the development of a domestic set of seven criteria & indicators, six of this relate to forest conditions, attributes, functions, or benefits. The seventh relates to the overall policy framework that can facilitate sustainable forest management and support efforts to conserve, maintain, or enhance the conditions, attributes, and benefits captured in the first six criteria. This report begins with an introduction describing forest ecosystems and forest management in Canada, explaining the area of forest covered by the report, and indentifying Canada-specific forest management characteristics to help place the criteria & indicators framework in context. The main section contains reports on the criteria, each with an introduction and reports on the corresponding indicators (what is being measured, indicator data or factual description, information sources). The final section contains a summary of all the criteria as well as an overview of Canada's ability to report on them and plans to enhance reporting capability in the future. Includes glossary.
