Snags are highly important for many wildlife species and ecological processes. In this study, we analyzed the relationship between snags topographic factors in a secondary forest plot South China. Data on 544 were collected recorded from 236 subplots permanent (400 subplots). The frequency of Castanopsis carlesii Schima superba was higher than that other species. derived mostly saplings small t...

Large wildfire events in coniferous forests of the western United States are often followed by postfire timber harvest. The long-term impacts of postfire timber harvest on fire-associated cavity-nesting bird species are not well documented. We studied nest-site selection by cavity-nesting birds over a 10-year period (1994–2003), representing 1–11 years after fire, on two burns created by mixed ...

Urbanization is causing fragmentation of natural areas and impacting urban wildlife populations. Sustainability their habitat in arboriculture has focused on three key areas: retaining snags beneficial-tree features (e.g., hollows/cavities), education arborists the public, adoption systems-level thinking into (i.e., consideration risk matrices pruning objectives). We surveyed 805 using an inter...

The first stage in an adaptive finite element scheme (cf. [CAS95, bor1]) consists in creating an initial mesh of a given domain Ω, which is used to perform an initial computation (for example a flow solver). A size specification field is deduced (e.g. at the vicinity of each mesh vertex, the desired mesh size is specified), based on the numerical results. If the mesh does not satisfy the size s...

Abstract Background Snags (standing dead trees) are important biological legacies in forest systems, providing numerous resources as well a record of recent tree mortality. From 1997 to 2017, we monitored snag populations drought-influenced mixed-conifer and ponderosa pine ( Pinus ) forests northern Arizona. Results Snag density increased significantly both types. This increase was driven large...

Features of Spatial Snag Distribution in a Beech-Fir Forest With the participation of about 65% in the total growing stock of conifers, silver fir is the most important andthe best represented conifer species in Croatia. The increasing share of sanitary felling in the annual felling plansdemands that special attention be paid to the health status of fir forests and the quantity of unpla...

Snags (standing dead trees) are important components of forest ecosystems that, among other benefits, provide critical habitat for many species wildlife, but also represent safety concerns to firefighters, workers, and the public. We identified factors that influence fall rates lodgepole pines, Pinus contorta Dougl. ex Loud., killed by bark beetles during a severe regional-scale outbreak mounta...

Abstract Background The epidemic Dendroctonus rufipennis (spruce beetle) outbreak in the subalpine forests of Colorado Plateau 1990s killed most larger Picea engelmannii (Engelmann spruce) trees. One quarter century later, snags are beginning to fall, transitioning deadwood (down woody debris) where they may influence fire behavior, regeneration, and habitat structure. Methods We tracked all fa...
