Dataset on tree occurrence from point-centred quarter (PCQ) plotsSampling Description
Study Extent
The study was carried out within the Anamalai Tiger Reserve (ATR), Tamil Nadu, India (core zone: 958 km², (10°22' - 10°56'N, 76°815' - 77°418'E) and the adjoining Valparai Plateau (220 km², 10°24- 10°46'N, 76°82' - 77°05'E) in the Anamalai Hills of the Western Ghats. Field surveys were carried out in rainforest fragments on the Valparai Plateau and larger rainforest tracts in ATR. Some coffee plantations were also sampled.Sampling
Field study in the 2000-3 season was carried out between January and June of the corresponding years. The 2019 data were gathered mostly between January and Decemeber 2019. Within each of the sites (rainforest fragment, mature rainforest, coffee or cardamom plantation), trees (>30 cm girth at breast height) were recorded in 15–30 point-centred quarter (PCQ) samples spaced about 100 m apart in each fragment, noting tree girth, radial distance from the point, and species identity.Quality Control
Trees were directly identified in the field or herbarium specimens collected to identify using field guides cited in identification references. Taxa that could not be identified to species were identified to Genus or Family, or occasionally higher taxa. Species names were updated to GBIF taxonomy using the species name matching tool.Method steps
- Data from multiple years was first combined. Then the full dataset prepared was uploaded to Zenodo (https://zenodo.org/doi/10.5281/zenodo.10002516). For the GBIF upload, data from 2005 was dropped as tree species was not recorded that year. Using R code the CSV files from Zenodo was converted to GBIF Darwin Core format for upload.
