A regional assessment of the ecological effects of chipping and mastication fuels reduction and forest restoration treatments. Project Title: A regional assessment of the ecological effects of chipping and mastication fuels reduction and forest restoration treatments. ABSTRACT: Over the past several years, fire managers have increased their use of mastication treatments, the on-site disposal of...

Biomass burning produces black carbon (BC), effectively transferring a fraction of the biomass C from an actively cycling pool to a passive C pool, which may be stored in the soil. Yet the timescales and mechanisms for incorporation of BC into the soil profile are not well understood. The High Park fire (HPF), which occurred in northwestern Colorado in the summer of 2012, provided an opportunit...

Fallen trees decompose on the forest floor and create habitats for many species. Thus, mapping fallen allows identifying most valuable areas regarding biodiversity, especially in boreal forests, enabling well-focused conservation restoration actions. Airborne laser scanning (ALS) is capable of characterizing forests underlying topography. However, its potential detecting under varying condition...

nitrification due to a high C/N ratio in litter (Vitousek et al., 1979), temporary sorption on ion exchange sites The mechanisms by which forest ecosystems retain or lose soluble (Vitousek et al., 1979) and in the case of P, fixation or inorganic nutrients after disturbance are well known, but substantial amounts of soluble organic nutrients may also be released from cut sorption on soil (Wood ...

Human-induced changes of the environment and their possible impacts on temperate forest understory plant communities have been examined in many studies. However, the relative contribution of individual environmental factors to these changes in the herb layer is still unclear. In this study, we used vegetation survey data covering a time period of 21 years and collected from 143 permanent plots ...
