Fall-down Rates of Subalpine Fir Snags at Sicamous Creek: Implications for Worker Safety and Habitat Supply
نویسنده
چکیده
Current regulations require that all dead trees over m tall are felled when an area is being logged (Workers’ Compensation Board regulation .). This clearly protects workers because tree-falling, especially handfalling, is more dangerous when other trees, live or dead, could interfere with the falling tree. Snags must also be removed within . tree heights of work areas. This buffer is intended to decrease the risk that a worker in a block will be injured by a falling dead tree. However, there are several costs to snag-falling: • Ecological damage. Many wildlife species require snags, including % of bird species and % of mammal species in British Columbia (Bunnell and Kremsater ). Different species require different stages of decay, from recently dead snags to soft stubs, and many species require canopy-sized snags. Many other, lesser-known species are linked to snags, including lichens (Goward and Arsenault ), fungi, and invertebrates— in Sweden, species of invertebrates are threatened or Fall-down Rates of Subalpine Fir Snags at Sicamous Creek: Implications for Worker Safety and Habitat Supply

Interactive comment on “Time since death and decay rate constants of Norway spruce and European larch deadwood in subalpine forests determined using dendrochronology and radiocarbon dating” by M. Petrillo et al
The decay rate of standing deadwood, i.e., of snags, is slower than that of downed deadwood in contact with the forest floor. We agree with Dr. Anger’s opinion that this may be an important reason why clear age differences in the decay classes 1 – 3 are missing. Some snags fall earlier others later. This overshadows a clear age trend in decay. If the rate at which snags of larch fall down on th...
متن کاملSnag longevity in relation to wildfire and postfire salvage logging
Snags create nesting, foraging, and roosting habitat for a variety of wildlife species. Removal of snags through postfire salvage logging reduces the densities and size classes of snags remaining after wildfire. We determined important variables associated with annual persistence rates (the probability a snag remains standing from 1 year to the next) of large conifer snags ( 23 cm diameter brea...
متن کاملInteractive comment on “Time since death and decay rate constants of Norway spruce and European larch deadwood in subalpine forests
their discussion, the authors refer to studies that showed that the decay rate of standing dead wood is slower than dead wood in contact with the forest floor. This contributes to explain the absence of clear differences in properties in classes 1-3. The same argument might potentially be used to explain the differences in decay rates of larch and spruce. Assessing the time elapsed standing of ...
متن کاملWater use by whitebark pine and subalpine fir: potential consequences of fire exclusion in the northern Rocky Mountains.
In subalpine forests of the northern Rocky Mountains, fire exclusion has contributed to large-scale shifts from early-successional whitebark pine (Pinus albicaulis Engelm.) to late-successional subalpine fir (Abies lasiocarpa (Hook.) Nutt.), a species assumed to be more shade tolerant than whitebark pine and with leaf to sapwood area ratios (A(L):A(S)) over twice as high. Potential consequences...
متن کاملSummer Habitat Use by Snowshoe Hare and Mountain Cottontail at Their Southern Zone of Sympatry
The snowshoe hare (Lepus americanus) is a habitat specialist with a broad geographic range associated with boreal and subalpine forests in North America (Hall 1981, Hodges 1999a,b). It reaches southern range limits in the Southern Rocky Mountains in northern New Mexico, USA. Here, scant and mostly anecdotal evidence suggests that it is restricted to high-elevation, subalpine conifer forests dom...
