1c and d) and most were trembling aspen under 6 m in height. Salvage logging (BS) removed 55% of the snag volume and 50% of the snag density and further forest renewal activities including windrowing, planting, and tending (BSP and BSPT) removed an additional 15% of the volume Historical changes in the disturbance history of eastern forests have dramtically influenced their current composition and structure.

Bat activity in burned areas was either equivalent or higher than in unburned stands of mixed-conifer forest for all six phonic groups (Fig. 2, Table S1).Of the six phonic groups, four groups had activity levels significantly greater in burned stands than in unburned stands in at least one level of fire severity (Fig.

We quantified the interactions between the focal plants and their animal mutualists in the last European relict of old-growth lowland forest in After analyzing aerial photos from the early s of unharvested forest on aboutacres, scientists found that mixed-severity fires were most prevalent, regardless of forest type.

Forest soil scientists have long been concerned with soil carbon (C) and nitrogen (N) because these are often the master variables determining soil fertility (Pritchett and Fisher, ).In recent decades, knowledge of the role of soils as a source or sink for C on a global scale has become vital for assessing of changes in atmospheric CO 2 :// Wildlife response to natural disturbances such as fire is of conservation concern to managers, policy makers, and scientists, yet information is scant beyond a few well-studied groups (e.g., birds, small mammals).

Introduction: Definition and Geographical Localization of the Tropics and Subtropics Climate change affects populations of forest insect pests in a number of ways. We reviewed the most recent literature (–) on this subject including previous reviews on the topic.
We provide a comprehensive discussion of the subject, with special attention to insect range expansion, insect abundance, impacts on forest ecosystems, and effects on forest insect :// Regions of the Eastern Deciduous Forest.
Dyer The Eastern Deciduous Forest once occupied about 2, km2 (Delcourt and Delcourt ).

The role of such forests as habitat for specialized animal species is of concern. Preserva- Canada's boreal forest is a vast region comprising about one third of the circumpolar boreal forest that rings the Northern Hemisphere, mostly north of the 50th parallel.
Other countries with boreal forest, include Russia, which contains the majority, the United States in its northern most state of Alaska, and the Scandinavian or Northern European countries (e.g. Sweden, Finland, Norway and Previous forest disturbance significantly affected the post‐El Niño dung beetle species richness, abundance, and compositional similarity to pre‐El Niño condition (Figure 2a‐i), while all beetle responses varied significantly between drought‐only and fire‐affected forests in at least one of the post‐El Niño surveys (Figure 2a‐r Trees and forests play an incredible role in reducing storm water in several ways and removing or filtering pollutants that would otherwise wind up in our waterways.

With all data pooled, the effects of year, used to represent climate change drivers as a whole in both Model 1 (with only year as The word forest derives from the Old French forest (also forès), denoting "forest, vast expanse covered by trees"; forest was first introduced into English as the word denoting wild land set aside for hunting without the necessity in definition of having trees on the land.

Minnesota has some km2 (, acres) of old-growth forest, more than any other state in the east (Davis ). Forest regeneration is a key element in achieving sustainable forest management.
Partial harvest methods have been used extensively in temperate broadleaf and mixedwood ecosystems to promote regeneration on poorly stocked sites and to maintain forest composition and productivity.
