“…Birds are useful indicators of the habitat value of revegetation as they are easily detected and sufficiently abundant to provide quantitative data. Although many bird species are generalists, the fact that birds make extensive use of vegetation‐based habitat resources for food, shelter, and breeding, and are diversified over several trophic levels makes them potentially sensitive indicators of habitat change (Da Silva & Vickery ). Their high mobility also makes it likely that birds are useful indicators of landscape scale constraints on the habitat value of revegetation.…”

The effectiveness of revegetation in providing habitat for fauna is expected to be determined both by within-site factors and attributes of the landscape in which a revegetation site occurs. Most studies of fauna in revegetation have been conducted in landscapes that have been extensively cleared, modified or fragmented, and in Australia, predominantly in the southern temperate zone. We investigated how within-site vegetation attributes and landscape context attributes were related to bird species richness and composition in a chronosequence of post-mining rehabilitation sites within an otherwise intact landscape in tropical northern Australia. Our working hypothesis was that bird species richness in rehabilitating sites would be positively related to site vegetation structure and landscape context including (1) proximity to woodland and (2) the proportion of woodland within a 500-m buffer of rehabilitation sites. Within each of 67 sites, we sampled vegetation once and surveyed for birds eight times over 16 months. Landscape context variables were calculated using GIS. There were large differences between bird assemblages of woodland and rehabilitation sites and between age classes of rehabilitation. Bird assemblages were strongly related to site vegetation attributes across all rehabilitation sites. Proximity to woodland was only related to bird assemblages in rehabilitation sites older than 4 years old. We conclude that the relative importance of landscape context and site variables at any point in time will be a function of how closely vegetation within the revegetation site matches the habitat resource requirements of individual species.

“…Birds offer a good indicator animal group for assessing the success of ecosystem recovery and value of surrogate habitats (Bibby, 1999; Da Silva & Vickery, 2002; Gregory et al, 2003; Mekonen, 2017). The often dismissed post‐quarry sites can be key biodiversity spots attractive for nature and geo‐touristic exploration (Baczynska et al, 2018) among other post‐quarry site recovery schemes.…”

Abandoned post‐quarry sites have potentiality to be remodeled into natural‐wilderness areas, a desire especially in rapidly urbanizing and transforming landscapes. However, paucity of ecological information on post‐quarry sites limits nature‐based restoration, especially in the sub‐Saharan tropical landscape. This study investigated avifauna composition of post‐quarry sites in Ndarugu, Kenya, relative to non‐quarried sites for conservation role prioritization. Birds were censused in 166 point count stations using the fixed‐radius distance method. Land use land cover types within each point provided the variables for explaining bird occurrence. Observed bird species were classified into functional guilds, avifaunal composition assessed, and bird data subjected to multivariate analysis. In total 158 species, 128 in post‐quarry and 123 in non‐quarried sites, were recorded. Bush‐ and forest‐related species were dominant, constituting over 55% of total observed birds, in both site categories. Six wetland‐related species were detected only in quarried sampling sites. Mann–Whitney statistical tests returned a significant effect of land use category on bird species richness, abundance, and diversity, all higher in post‐quarried than in non‐quarried sites (p < 0.05). Emergent natural shrubs, quarry cliffs, and cultivated farms were most influential to bird community structuring. Nonmetric multidimensional scaling and cluster analysis revealed four functional groups of birds whose species richness increased with number of post‐quarried sampling sites in a cluster. Unique physical features of post‐quarry sites and emergent vegetation types, can be partially mimicked in nature‐oriented rehabilitation planning for long‐term social and ecological benefits.

“…Among wildlife taxa, birds are conspicuous early responders to forest restoration (Dunn 2004, MacGregor-Fors et al 2010, Rolo et al 2017). Because of their diverse life history strategies including wide variation in diet, specialized foraging strategies, and microniche preferences, birds can act as an indicator taxon for recovering ecological complexity during forest restoration (Da Silva and Vickery 2002). In addition, birds provide ecosystem functions that facilitate forest recovery including seed dispersal, pollination, and herbivorous insect reduction (Sekercioglu 2006, Morrison and Lindell 2012, Lindell et al 2013, Frick et al 2014, Carlo and Morales 2016.…”

Bird habitat creation is often a goal of tropical forest restoration because bird-driven ecosystem services can accelerate forest recovery. However, resident tropical bird responses are not well characterized in the earliest years following restoration action. During a five-year study of the bird community in an experimental tropical forest restoration, we examined temporal trends in bird activity and diversity and the effects of habitat variables on the distribution of bird species within the site. Our site consisted of 16 replicate plots with 1, 2, 4, or 8 native tree species planted into former heavily-grazed pasture. Four years after tree planting, we observed a 3-fold increase in bird activity and 11-fold increase in species richness compared to preplanting. We also found changes in proportions of habitat guilds, with marked declines in open country birds and increases in birds associated with brushy, early secondary growth, and forest edge habitats. Number of bird species observed differed strongly between plots four years postplanting. Using a multispecies occurrence model under a Bayesian framework, we considered possible reasons for these differences related to plot content and context. Content features within plots ("content"), including number of tree species planted, canopy cover, tree species identity, and presence of legacy trees, did not explain differences in number of bird species observed, potentially because of small plot size relative to bird mobility. Neighborhood features ("context") of each plot did explain differences; more bird species were detected in plots with more adjacent woodland and farther from actively grazed pasture. Our results demonstrate that planting native tree species in highly degraded sites can generate rapid, positive responses from tropical bird communities. These responses are likely mediated by surrounding habitat matrix, which influences rates of bird community recovery. Considering site context can improve predictions of fine-scale distribution of bird activity and diversity within restoration sites. Rétablissement de l'activité et de la richesse aviaire au cours des premiers stades de régénération d'une forêt tropicale RÉSUMÉ. La création d'habitat pour les oiseaux est souvent envisagée dans le cas de restauration de forêts tropicales parce que les services écosystémiques découlant de la présence des oiseaux peuvent accélérer le rétablissement forestier. Toutefois, le comportement des oiseaux tropicaux résidents n'est pas bien connu au cours des premières années suivant les activités de restauration. Pendant cinq années, nous avons examiné les tendances temporelles de l'activité et de la diversité des oiseaux et l'effet des variables d'habitat sur la répartition des espèces d'oiseaux dans un site d'étude au coeur d'une forêt tropicale faisant l'objet d'une restauration expérimentale. Notre site d'étude était composé de 16 parcelles répétées comportant 1, 2, 4 ou 8 espèces d'arbres indigènes plantés dans d'anciens pâturages extrêmement broutés. Quatre ans après la ...
