Data on tree occurrence were collected between January 1998 and June 1999 using point-centred quarter plots in Kalakad-Mundanthurai Tiger Reserve, Tamil Nadu, India. A total of 21 transects were surveyed, including 14 in tropical rainforests and 7 in abandoned plantations and plantation forest edges as described elsewhere (Raman 2001, Mudappa 2001, Raman and Sukumar 2002, Raman et al. 2005).Sampling Description
Study Extent
This study was carried out in Kalakad-Mundanthurai Tiger Reserve (8° 25' to 8° 53' N and 77°10' to 77°35' E), Tamil Nadu, at the southern extremity of the Western Ghats mountain range in India. Study transects were established at the intensive study sites located around forest camps at Kannikatti (740 m asl, 8°37' N and 77°16' E), Sengaltheri (1040 m asl, 8°31' N and 77°26' E), and Kakachi (1220 m asl, 8°33' N and 77°24' E) in KMTR. These areas contain rainforests ranging in altitude between 500 m and 1,400 m. A total of 21 transects were surveyed once, including 14 in rainforests and 7 in abandoned plantations and plantation forest edges as described elsewhere (Raman 2001, Mudappa 2001, Raman and Sukumar 2002, Raman et al. 2005).Sampling
Trees were surveyed along the 21 study transects using the point-centred quarter (PCQ) method. Along each transect, 13 PCQ plots were sampled (12 in the case of site P6), with successive plots spaced 50 m apart, giving a sample of 52 trees per site (48 trees in P6). Trees greater than 30 cm girth at breast height (GBH at 1.3 m) were recorded using the point-centred quarter method (PCQ). Using a tape measure, distance from plot centre to the middle of the bole and GBH were recorded for each tree. All trees in the PCQ plots were identified to species, or in a few cases to genus, using available field guides (Gamble 1935, Pascal and Ramesh 1997).Quality Control
Data transcribed from field ledgers into worksheets were carefully verified and updated to current taxonomy using the species lookup tool on GBIF.Method steps
- Data were first uploaded to Data Dryad and then were converted to GBIF format using R code. Raman, T. R. S., Mudappa, D. and Jeganathan, P.
