  • Data set on demography of trees monitored over 20 years in Uppangala permanent sample plot (UPSP) in undisturbed, old-growth wet evergreen Dipterocarp forest located within the Pushpagiri Wildlife Sanctuary in India's Western Ghats biodiversity hotspot. During 1989–1990, all trees ≥30 cm girth at breast height (gbh) were sampled in five north–south transects 20 m wide and 180–370 m long covering a total area of 3.12 ha. In 1992–1993, additional rectangular plots were established, bringing the total area sampled to 5.07 ha. In all, 3870 trees were identified, tagged, mapped, and provided with permanent dendrometer bands. Since then, the sampled area has been regularly censused at 3–5-year intervals, recording tree recruitment, mortality, and growth. We present data from censuses conducted in 1990–1993, 1994, 1997–1998, 2001–2002, 2007, and 2010. These data have been used to study the natural forest dynamics and to calibrate spatially explicit simulation models.

  • This data set reports woody plant species abundances in a network of 96 sampling sites spread across 22000 km² in central Western Ghats region, Karnataka, India . The database stores abundance and girth data for 76813 trees and lianas of 446 species collected in 96 sampling sites during 1996-1997. A total of 61965 individuals >10 cm girth at breast height (gbh) were recorded in 96 1-ha macroplots, while 14848 individuals <10 cm gbh but >1 m height were sampled in three 0.1-ha microplots located within each macroplot. Additional data regarding the stand structure (average canopy height, percent canopy cover, number of strata) and the level of degradation are available for the macroplots, along with environmental data derived from other sources and analyses, such as soil types, rainfall, length of the dry season, and altitude. These data have been used to produce ecological research papers as well as to elaborate conservation value maps and recommendations toward sustainable management of the forests of the central Western Ghats region. We have migrated the initial database available at http://esapubs.org/Archive/ecol/E091/216/default.htm to DataManager during the Pl@ntGhats project.

  • The site Crique Bastien is composed of two 3km-transects (20m wide). 2608 trees with dbh>=20cm have been recorded by Office national des forêts (ONF). No fauna inventories available. No under-storey plants inventories are available. Soils have been described using 3 samples (1.20m depth max.). No laboratory analysis available for soils.

  • Africadiv is a network of 1-ha forest monitoring plots spread across the moist forests in central Africa. The Cameroonian site of Mindourou II is composed of 12 1-ha forest plots. The following data are available for the different plots at this site: Structure - DBH of all trees ≥ 10 cm DBH : n = 5 598 Structure - Tree height : n = 920 Structure - Trunk height : n = 667 Structure - Crown diameter : n = 233 Identification rate - species-level : 56.4 % Identification rate - genus-level : 26.2 % Identification rate - family-level : 11.7 % Identification rate - unidentified : 5.7 % Soil samples & analyses available : YES Geolocation : GPS points and laser measurements (distance, vertical & horizontal angles) every 20 m on the contour of the plot. These data are routinely collected and used by AMAP research unit (IRD) and partners (LaboSyst, Yaoundé 1 University). Scientific collaboration are welcomed, please get in touch with a Point of contact.

  • This “Inventaire Papetier” was conducted by the CTFT in 1975. The block covers 40 556 ha. 25 735 trees have been inventoried in 169 plots (82 ha) Pre-census DBH is 15 cm on all plot (originally trees with DBH 10-15cm have been measured on one plot out of 10 but not included in the digital version) DBH have been measured by classes : 15-20 cm for the first class and with a range of 10 cm since 20 cm. Plots have been located on GIS in 2009 using original maps and field note-books (indicating slopes, rivers, etc...).
