Data for: The role of landscape in shaping bird community and implications for landscape management at Nanjing Lukou International Airport

Understanding the patterns of bird diversity and its driving force is
necessary for bird strike prevention. In this study, we investigated the
effects of landscape attributes on phylogenetic and functional diversity
of bird communities at Nanjing Lukou International Airport (NLIA). Bird
identifications and counting of individuals were carried out from November
2017 to October 2019. Based on the land cover data, the landscape was
divided into four main types, including farmlands, woodlands, wetlands and
urban areas. Bird phylogenetic and functional diversity were strongly
affected by landscape matrix types. Bird species, phylogenetic and
functional richness were highest in woodlands, while phylogenetic and
functional structure were most complex in wetlands. We found that related
carnivorous birds occupied most niches at the NLIA. Moreover, bird
assemblages exhibited phylogenetic and functional clustering in all
landscape matrix types, which meant environmental filtering governed
community assembly. Landscape attributes of different matrix types
influenced phylogenetic and functional diversity of bird communities.
Landscape diversity affected bird functional structure positively, and the
mean of patch area in the landscape had the strongest explanatory effects.
To prevent bird strikes, we suggest that more small-area woodlands with
low levels of aggregation can be considered and farmlands should be
patchier and more regular. At landscape level, the number of patches can
be adjusted to reduce the frequency of bird activities.
