Selective logging and plantation impacts on avian abundances in Malaysian Borneo

If you wish to use these data, please contact grcerullo AT gmail DOT com This dataset represents a geolocated and standardised bird sampling effort spanning a selective logging and plantation gradient in Sabah, Malaysian Borneo, and consists of 25,039 individual bird detections of 210 species. Habitat types sampled using point counts include: Primary forest (6 sites, 72 point counts) Restored forest (once-logged forest subjected to liana cutting and enrichment planting) (4 sites, 48 points) Once-logged forest left naturally regenerating (5 sites, 60 points) Twice-logged forest (8 sites, 96 points) Albizia falcataria plantations, grown on 12-yr rotation (3 sites, 36 points) Eucalyptus pellita plantations, grown on 6-yr rotations. (3 sites, 36 points). Sites were seperated by >1 km and all points within 12-point transects were seperated by >250 m to ensure independence. Point counts involved 2 experts (Daniel Kong, DK, or David Edwards, DE) conducting 15-minute point counts at each point location, repeated over three consecutive days. Data collected by DK also includes distance to bird, whereas data collected by DE included all species detected in 100 m radius, without recording distances. These data support the findings of Cerullo et al. 2025. Their collection was supported by a Peter Scott Studentship at Cambridge University to Gianluca Cerullo. Further information on sampling protocol and the study area can be found in Chapter 3 (and the appropriate Appendices) of GC's thesis: https://www.repository.cam.ac.uk/items/617f455b-2eb5-4b14-903a-9e6bbd968886 (this section will be updated upon manuscript publication). A description of the data columns is as follows: spp common name of the species abundance number of individuals detected on the point count habitat type of primary, selectively logged or plantation habitat (see above) site site name - sites consist of 12 points with sites seperated by > 1km point point name day day of sampling over three consective days year year of sapling (one of 2008, 2011 or 2022) flyover was the bird a flyover (1). Only relevant for DK. DE point counts already remove flyovers. distance estimated distance of bird to surveyor. Only recorded by DK. adjacent was the bird recorded in an adjacent habitat type (e.g. in a riparian forest buffer when the point count was in a plantation?) adjacent_hab if adjacent = TRUE, what was the adjacent habitat? date date of point count time time of point count (point count orders across consective days were shuffled) date_time concatenation of data and time longitude longitude of point count location latitude latitude of point count location sampler sampler carrying out points counts (one of DK or DE) logging_year year that the first logging event took place restoration_year year that the first restoration (liana cutting or enrichment planting) took place time_since_logging time since selective logging (relative to the survey date) time_since_restoration time since restoration (relative to the survey date) plantation_age age of tree plantation (i.e. years since planting) abc50 mean above-ground carbon in 50 m buffer around point count (derived from https://www.sciencedirect.com/science/article/pii/S0006320717310790) abc100 mean above-ground carbon in 100 m buffer around point count (derived from https://www.sciencedirect.com/science/article/pii/S0006320717310790) cth50 mean canopy tree heigh in 50 m buffer around point count (derived from https://www.sciencedirect.com/science/article/pii/S0006320717310790) cth100 mean canopy tree heigh in 100 m buffer around point count (derived from https://www.sciencedirect.com/science/article/pii/S0006320717310790) latinname latin name of bird species family1 family of bird species order1 order of bird species trophic.level one of carnivore; herbivore; omnivore primary.lifestyle one of aerial; generalist; insessorial; terrestrial SHAPEFILES ARE ALSO PROVIDED FOR: SabahSoftwoodCompartments: the area, size and location of different plantation compartments within the Sabah Softwood tree plantation area.
