SALVAGING TIMBER; SCUTTLING FORESTS The Ecological Effects of Post-Fire Salvage Logging

ثبت نشده
چکیده

Most native species of plants and animals inhabiting forest ecosystems evolved with natural adaptations to the patterns and processes of fire disturbance and recovery.[1] One of the effects of fire disturbances is the creation of dead trees, both standing "snags" and downed logs. Fire-killed snags and logs serve vital roles in the structure and function of healthy forest ecosystems in general, and are especially important for natural recovery processes following fire events. [2] They provide food and shelter to wildlife, fish, and numerous insects, microbes, and fungi that are vital to post-fire recovery and long-term site productivity, they help retard surface water runoff and help retain and build soil, they help cycle nutrients and water to plants and soil, and snags that fall across streams provide links between terrestrial and aquatic ecosystems. [3] Indeed, a forest ecologist could argue that for the sake of healthy wildlife and plant populations, fertile soil, and clean water, large-diameter snags and logs are some of the most valuable trees in the forest.

Limited salvage logging effects on forest regeneration after moderate-severity windthrow.

Recent conceptual advances address forest response to multiple disturbances within a brief time period, providing an ideal framework for examining the consequences of natural disturbances followed by anthropogenic management activities. The combination of two or more disturbances in a short period may produce "ecological surprises," and models predict a threshold of cumulative disturbance sever...

Post-Fire Seedling Recruitment and Morpho-Ecophysiological Responses to Induced Drought and Salvage Logging in Pinus halepensis Mill. Stands

Salvage logging is the commonest post-fire emergency action, but has unclear ecological effects. In the Mediterranean Basin, drought periods and fire regimes are changing and forest management should be adapted. In summer 2009, a mid-high severity fire burned 968 ha of Aleppo pine (Pinus halepensis Mill.) forest in southeast Spain, which was submitted to salvage logging six months later. In spr...

Influence of Fire and Salvage Logging on Site Occupancy of Spotted Owls in the San Bernardino and San Jacinto Mountains of Southern California

Fire over the past decade has affected forests in the San Bernardino Mountains of southern California, providing an excellent opportunity to examine how this disturbance, and subsequent post-fire salvage logging, influenced California spotted owl (Strix occidentalis occidentalis) breeding-season site occupancy dynamics there and in the nearby San Jacinto Mountains. Using occupancy survey data f...

Effects of blowdown, salvage logging, and wildfire on regeneration and fuel characteristics in Minnesotaâ•Žs forests

Effects of blowdown, salvage logging, and wildfire on regeneration and fuel characteristics in Minnesota's forests" (2011). ABSTRACT The patchiness resulting from a sequence of recent disturbances – blowdown, salvage logging, and wildfire – provided an excellent opportunity to assess the impacts of these disturbances, singly and in combination, on (1) wildfire severity (2) post-disturbance vege...

New Insights into the Consequences of Post-Windthrow Salvage Logging Revealed by Functional Structure of Saproxylic Beetles Assemblages

Windstorms, bark beetle outbreaks and fires are important natural disturbances in coniferous forests worldwide. Wind-thrown trees promote biodiversity and restoration within production forests, but also cause large economic losses due to bark beetle infestation and accelerated fungal decomposition. Such damaged trees are often removed by salvage logging, which leads to decreased biodiversity an...
