A current paradigm in conservation biology is that forest harvest practices that better approximate natural disturbance processes are more likely to conserve biodiversity. We contrasted bird communities in three replicate stands in each of 1, 13–15, and 22–28 yr old forests following wildfire and harvest in north-central Alberta, Canada. Stands were chosen from old (.120 yr) boreal mixedwood fo...

Throughout the Midwest United States, agricultural and urban development have fragmented natural areas, with a disproportionate effect on forests wetlands. The resulting habitat loss, compounded spread of white-nose syndrome (WNS), has caused precipitous population declines in several forest-obligate bat species. In 2019, we discovered remnant northern long-eared (Myotis septentrionalis Trouess...

Johansson, T. 2006. The conservation of saproxylic beetles in boreal forest: importance of forest management and dead wood characteristics Doctoral dissertation ISSN 1652-6880, ISBN 91-576-7115-X Forest management has altered the age structure, tree species composition and dead wood availability of Swedish boreal forests. As a consequence, many saproxylic (wood living) insect species have decre...

Reintroducing fire to manage vegetation and fuel may have poorly understood consequences for wildlife. Prescribed burning can reduce down wood and snags that provide critical habitat and mechanical thinning designed to reduce fire hazards may alter forest structures that are preferred by some species. Moreover, fine scale fuel treatments may alter wildlife and habitat dynamics within the larger...

Abstract The individual or grouped retention of habitat trees in managed multiple-use forests has become an approach used to protect biodiversity-related structural attributes typically found old close-to-nature forests. This study focuses on the effect one such Baden-Württemberg, Germany, ten years after its introduction. Specifically, we asked: (1) How effective are tree groups (HTGs) at prov...

The system utilizes IoT, echolocation, picture handling, man-made brainpower, and route framework innovation to distinguish between close far snags for the client. If visually impaired individual falls or has another issue, will send an admonition assigned individual. It distinguishes object before this with a specific reach. At point when item is recognized signal sound given client as sign. W...

--The habitat requirements of open nesting birds were examined in 19, five hectare, plots arranged along an altitudinal gradient in western Montana. Seven, mature forest birds were examined in detai 1. Percent shrub and low canopy cover {0.5-1.5m), mid-canopy cover {8-25m), and the number of large diameter stems {25-50 em dbh) were of major importance to this avian co11111unity. Increased avian...
