FIGURE 1. Aerial view of the Group Selection openings, Fleet Creek. Introduction Increasingly in British Columbia, forest managers are seeking to use a greater variety of silvicultural system options, and reduce reliance on clearcutting. In BC and the Pacific Northwest, the shift in forest practices in response to changing environmental and land use attitudes is well-documented (Kohm and Frankl...

This study used a video-based hazard perception dual task to compare the hazard perception skills of young drivers with middle aged, more experienced drivers and to determine if these skills can be improved with video-based road commentary training. The primary task required the participants to detect and verbally identify immediate hazard on video-based traffic scenarios while concurrently per...

A source separation program for household kitchen waste has been in place in Beijing since 2010. However, the participation rate of residents is far from satisfactory. This study was carried out to identify residents' preferences based on an improved management strategy for household kitchen waste source separation. We determine the preferences of residents in an ad hoc sample, according to the...

The negative influence of timber harvesting on the forest environment is reflected through damage to residual trees, regeneration, and soil. Considering that skidding, a popular extraction method, can cause substantial severe remaining stand, aim this research was determine trees during skidding by an LKT 81T cable skidder, including oxen bunching. conducted in eastern Bosnia Herzegovina, uneve...

Fire modifies vegetation dynamics in terrestrial ecosystems. Abundant literature has studied the post-fire effects with satellite sensors; however, relatively fewer studies have used unmanned aerial vehicles (UAVs) to assess of greenness prior and immediately following prescribed fires. Using multispectral sensors mounted on UAVs, we documented results normalized difference index (NDVI) as a pr...

Abstract We investigated how thinning intensity and rotation length affect radiative forcing, thus climate warming or cooling, through changes in albedo carbon stocks Norway spruce (Picea abies Kart. (L.)) stands. Forest ecosystem model simulations were conducted under the current on sub-mesic sites central Finland (62oN). Even-aged management regime with a business-as-usual (baseline) from bel...
