People’s attitudes towards forest stand characteristics including deadwood are becoming increasingly relevant in sustainable forest management. The aim of this study is to investigate people’s attitudes towards deadwood in forest. The study was carried out in the Rakhiv region (Ukraine) characterized by high importance of forest resources for the local community and economy. People’s opinions were collected through the face-to-face administration of a questionnaire to 308 respondents. The survey investigated three aspects: importance of deadwood in forest; people’s perceptions of positive and negative effects of deadwood in forest; effects of presence and amount of deadwood in different types of forest on people’s aesthetical preferences. The results show that the majority of respondents consider deadwood as an important component of the forest, but generally they prefer intensively managed forests without deadwood. According to the respondents’ opinions, the most important positive effect of deadwood is a contribution to stand dynamics, while the most important negative effect is an increasing risk of insects and diseases.

Populations of arboreal marsupials, small ground-dwelling mammals, reptiles and amphibians were assessed in forest before and after logging. Different levels of canopy retention were specified to estimate the effect of varying intensities of logging on these fauna. The logging treatments imposed were; unlogged, and the retention of approximately 72%, 58% and 30% of the original canopy cover. This corresponded to 62%, 52% and 21 % retention of the original tree basal area on each logged area. The objectives of the study were to determine the sensitivity of species to logging, both in terms of the intensity of the initial impact and in terms of the time to recovery following disturbance, and to develop methods for managing areas within wood production forests where special wildlife values have been identified. A total of 53 species was recorded in the 500 ha study area, only 18 (34.0%) of which were abundant enough for assessments to be made about the effects of logging. The arboreal marsupials, in particular the Greater Glider Petauroides volans, were among the species more sensitive to logging disturbance. The small, ground-dwelling mammals and the reptiles that were sampled adequately in this study appeared to be relatively unaffected by logging or they recovered quickly (most within eight years, and probably all within 10?15 years) following logging. Despite a large survey effort, insufficient data were available to assess the effects of logging on most species of frogs, although two species may have been advantaged. The species requiring management consideration include those that declined as a result of logging, but which had not recovered within eight years (the Greater Glider, the Yellow-bellied Glider Petaurus australis, the Sugar Glider P. breviceps, and the skink Niveoscincus coventryi), the species that declined in both logged and unlogged areas (the frogs Pseudophryne bibronii, Limnodynastes peronii, Geocrinia victoriana and Heleioporus australiacus), and the species for which the data were too sparse to make any assessments. It is unclear when the species most disadvantaged by integrated logging, that is, the large gliding possums, will recolonize the logged areas. The persistence of these gliders was attributed to the retention of unlogged forest within and adjacent to logged areas. This highlights the role of riparian reserves ("wildlife corridors") and filter strips in retaining residual populations of the Greater Glider and the Yellow-bellied Glider until the logged areas are suitable for recolonization, and the importance of determining the effective size for these unlogged reserves. The data were not sufficient to determine conclusively whether reduced logging intensity at the levels applied was a better option than standard logging practices for managing populations of gliding possums in these forests. The results of this study, which was conducted in a forested landscape that was multi-aged but predominantly unlogged, may not be comparable to intensively-managed forests in which there is a lower proportion of unlogged forest and where multiple logging events have occurred.

Abstract We evaluated how forest type, vegetation structure in trapping webs, and proximate forest types influenced localized (~6.35 hectares) abundances for commonly captured small mammals in northern California, USA. We trapped from May to August of 2011–13 in 69 forest patches that represented: (1) clearcuts (3–5 years postharvest), (2) 10–20 year-old conifer plantations, (3) rotation-aged conifer stands, and (4) Watercourse and Lake Protection Zones. We captured 11 species; four in sufficient numbers for regression modeling. Our average abundance estimates for the study were 4.57 (standard error [SE] = 0.43), 0.32 (SE = 0.11), 0.90 (SE = 0.30), and 0.25 (SE = 0.09) individuals per web location (~0.75 hectares) for Peromyscus spp., Neotoma spp., California ground squirrels, and Allen’s chipmunks. We found that web-level ground cover (shrubs and grass), downed wood, and types of forests containing our trapping webs best described small mammal abundances, whereas proximate forest types were not important. Our results indicated that retaining localized structures in the form of understory shrub cover and downed wood positively influences small mammal abundance in intensively managed forests of northern California.

Competition For Resources

Non-timber forest products (NTFP) are emerging globally as a tool for the establishment of sustainable forest communities. They provide employment to various sectors of society, draw on local expertise and culture, and increase the outputs of forests. In recent years, NTFP have received accrued interest by the general public, governments and the private sectors of Canada. However, for the NTFP industry to enter mainstream Canadian industrial culture it is now critical to attempt the integration of the timber industry with the NTFP industry to benefit both sectors. NTFP can be harvested from four types of environment: wild stocks from timber-productive forests, wild stocks from non-timber-productive forests or lands, managed stocks from intensively managed forests, and domesticated stocks from agricultural systems. A large body of evidence suggests that NTFP management and harvest can serve the forest industry in many ways. There are four possible types of interaction between the NTFP and timber industries: independent resource use, competition for resources, complementary resource use and symbiotic resource use. Integration of both industries in a sustainable manner will need to be supported with research that address economic, social, policy and ecological questions. Key words: NTFP, sustainability, biodiversity, community forestry
