“…Importantly, there was no corresponding decline in conifer specialists. A similar positive influence on bird communities by a higher proportion of larger (DBH ≥ 70 cm) retained broadleaves was found in a recent study from the Czech Republic in managed spruce forests (Kebrle et al, 2021).…”

“…density and proximity of surrounding production trees), limited the capacity of our study to detect any threshold requirements for GTR, an important consideration for forest owners and managers. Studies in Central Europe have made efforts to find such thresholds for "habitat trees" to mitigate the effects of production forestry on organisms depending of structures provided by these trees (Bütler et al, 2013;Kebrle et al, 2021). Finding thresholds for retained trees could be possible in Sweden in the future when the pool of mid-aged stands with large, retained broadleaves have increased.…”

“…coarse bark, trunk cavities and coarse branches, throughout the stand's rotation period, and iii) function as "stepping-stones" to enhance dispersal and connectivity in managed landscapes (Harris, 1984;Franklin et al, 1997). A large number of studies have evaluated the capacity of this practice to mitigate forestry impacts on biodiversity (Rosenvald and Lõhmus, 2008;Gustafsson et al, 2010;Fedrowitz et al, 2014), across a variety of species groups including insects (Horák, 2017;Koch Widerberg et al, 2018), lichens (Hofmeister et al, 2016), and birds (Gutzat and Dormann, 2018;Basile et al, 2019;Kebrle et al, 2021). However, since the practice is relatively new, most of these studies focus on conservation benefits soon after final felling (Söderström, 2009).…”

“…This also concurs with the study by [21] which describes that bird and plant taxa associations within habitats are attributed to particular foraging resources that different plant species provide. Thus, the plant diversity influences generalist species and negatively affects specialist species [22]. Furthermore, despite the differences in ecological conditions, such similarity of plantation forest and farmland habitat also perhaps due to short distances between the habitats, the abundance of food insects, and shared nesting materials [23].…”

“…The type and density of vegetation coverage of an area are the deterministic factors responsible for bird species richness, diversity, and abundance distribution [25] as the birds' species and specific plant taxa associations within habitats are mediated by particular feeding resources that different plant species provide [21]. Moreover, the presence and volume of broadleaf and mixed forest cover influence bird species (both generalists and specialists) significantly as the increase in broadleaf within the forest could enhance the diversity of birds, decreasing isolation levels of broadleaf dependent birds and increasing physical connectivity of species [22,39,40].…”

Background: Birds are among essential taxa in various ecosystems where their presence/absence and status indicate conditions of the habitats. Bird watching can bring economic resources to communities diversifying their livelihoods and contributing to biodiversity conservation in areas of bird habitats. Hence, a detailed understanding of species biogeography, diversity, and abundance is critical ecological information to evaluate or develop conservation strategies. The present study was conducted to assess species diversity and abundance of avifauna during wet and dry seasons of 2021 implications for conservation and ecotourism development in the Suba forest, Central Ethiopia. Stratified random sampling technique was utilized to select sampling blocks from each habitat type. Data were collected using lines transect and points transect count methods. Diversity of the species was computed using the Simpson's and Shannon-Weiner diversity indices. A two-way ANOVA was applied to know the effect of habitat and seasonality on avian species richness and abundance. Results: A total of 132 birds belonging to 51 families were identified during the study period. Among the recorded bird species, 124 were found to be residents. Four were endemic to Ethiopia, six were endemic to Ethiopia and Eritrea, and seven were globally threatened. The highest, H' = 4.569, and the lowest, H' = 3.935, of bird species was observed in natural forest and farmland habitats during the wet and dry seasons, respectively. Approximately half of the recorded species were found to be common. The difference in habitat type and variation in the season had substantial effects on the species abundance and richness. Plantation forest and farmland habitats had more worth mentioning community similarity. The forest has frequently been visited by domestic tourists than foreign non- resident and foreign resident tourists in the last 10 years. Conclusions: Suba forest is abundant in avifaunal resources with high ecotourism potential but lacks functioning conservation efforts and research. Thus, effective conservation measures and further research in other aspects of the forest are required.

Meeting food/wood demands with increasing human population and per-capita consumption is a pressing conservation issue, and is often framed as a choice between land sparing and land sharing. Although most empirical studies comparing the efficacy of land sparing and sharing supported land sparing, land sharing may be more efficient if its performance is tested by rigorous experimental design and habitat structures providing crucial resources for various species-keystone structures-are clearly involved. We launched a manipulative experiment to retain naturally regenerated broad-leaved trees when harvesting conifer plantations in central Hokkaido, northern Japan. We surveyed birds in harvested treatments, unharvested plantation controls, and natural forest references 1-year before the harvest and for three consecutive postharvest years. We developed a hierarchical community model separating abundance and space use (territorial proportion overlapping treatment plots) subject to imperfect detection to assess population consequences of retention harvesting. Application of the model to our data showed that retaining some broad-leaved trees increased the total abundance of forest birds over the harvest rotation cycle. Specifically, a preharvest survey showed that the amount of broad-leaved trees increased forest bird abundance in a concave manner (i.e., in the form of diminishing returns). After harvesting, a small amount of retained broad-leaved trees mitigated negative harvesting impacts on abundance, although retention harvesting reduced the space use. Nevertheless, positive retention effects on the postharvest bird density as the product of abundance and space use exhibited a concave form.
