Nova Scotia’s forested landscapes are degraded and under stress. As the province moves toward an ecological forestry management approach, land managers need more complete information about the relative biodiversity value of various habitats in landscapes that they manage to fully assess conservation consequences of different management options. To begin assessing the relative conservation value of different forest types, we surveyed bird communities in 18 forested wetlands (wooded bogs, tall shrub swamps, and treed swamps), mature upland forest stands, and regenerating upland forest stands in western Nova Scotia during the breeding season in 2017 and 2018. There were distinct differences among the bird communities in each forest type. Bird species diversity, overall abundance, and abundance of several guilds and species of conservation concern were higher in forested wetlands than in mature and regenerating upland forests. Bogs and shrub swamps had the highest number of species with strong habitat affinities, but treed swamps and mature sites had unique suites of strongly associated species and guilds — several of conservation concern. Regenerating sites were occupied mainly by forest-edge species and conservation value was low. Our study highlights the importance of forested wetlands to bird conservation and supports the idea that forested wetlands are avian diversity hotspots.

Transhumance is a traditional animal husbandry system, but its effects on grassland avian communities have not been dealt with in depth. In this study, we quantified the influence of transhumance on the grassland avifauna, in representative pseudo-alpine grasslands with no (NGG), low (LGG), and high (HGG) grazing intensity in the Pindos Mountains, Central Greece. Two point count surveys were conducted within 20 sites in each grassland during the bird breeding season of 2016. We assessed bird diversity indices and accounted for whether the recorded habitat and topographic variables were involved in their variation. A total of 25 bird species were recorded, with the grazed grasslands supporting the most species of high conservation value, while the NGG showed the highest bird diversity. Bird species richness and diversity increased with the decrease of vegetation height, vegetation height heterogeneity, and the increase of rock cover. Bird communities exhibited different patterns among the three grazing regimes and specific bird species of high conservation value appeared to prefer different grasslands. Six species preferred HGG, one preferred LGG, while two preferred NGG. Our study highlights the necessity of heterogeneous pseudo-alpine grasslands with short and tall grass areas in order to maintain highly diverse bird communities.

The One

Afforestation programs such as the one promoted by the EU Common Agricultural Policy have spread tree plantations on former cropland. These afforestations attract generalist forest and ubiquitous species but may cause severe damage to open habitat species, especially birds of high conservation value. We investigated the effects of young (<20 yr) tree plantations dominated by pineP. halepensison bird communities inhabiting the adjacent open farmland habitat in central Spain. We hypothesize that pine plantations located at shorter distances from open fields and with larger surface would affect species richness and conservation value of bird communities. Regression models controlling for the influence of land use types around plantations revealed positive effects of higher distance to pine plantation edge on community species richness in winter, and negative effects on an index of conservation concern (SPEC) during the breeding season. However, plantation area did not have any effect on species richness or community conservation value. Our results indicate that the effects of pine afforestation on bird communities inhabiting Mediterranean cropland are diluted by heterogeneous agricultural landscapes.
