Objectives:
 

Ecosystems worldwide are changing as a result of myriad anthropogenic processes viz., deforestation, fragmentation, hunting, changes in CO2 concentrations, increasing temperatures and altered rates of nitrogen deposition etc. It may be easy to measure these physical and chemical drivers with reasonable accuracy and precision. However quantifying possible ecological responses to these drivers is an extremely difficult task. Such effects are best perceived through long-term monitoring of permanent plots in ecological communities. The French Institute of Pondicherry in collaboration with the Karnataka Forest Department, installed permanent sampling plots in the Kadamakal Reserve Forest and Pushpagiri Wildlife Sanctuary with the main objective to document, analyses and model forest dynamics.

Materials and methods:

 
 
 

Uppangala forest is situated in the Kadamakal Reserve Forest (Coorg district) at the foothills of the Western Ghats, located between 12° 33' N latitude and 75° 39' E longitude (Fig 1a). The elevation ranges between 400 and 600 m a.s.l. It belongs to the Dipterocarpus indicus-Kingiodendron pinnatum-Humboldtia brunonis type of wet evergreen forests and is a part of the West Coast Tropical Forests of Champion and Seth's classification. Uppangala receives slightly more than 5100 mm per year and the dry season lasts 4.5 months.

Methods:
 

Sample designs and censuses

In 1985-86, the French Institute of Pondicherry, in collaboration with the Karnataka Forest Department, installed the first set permanent sampling plots in the logged compartment (A; Fig. 1b) of low elevation wet evergreen forest of Kadamakal Reserve Forest to monitor the post-logging forest dynamics (ca. 8.5 trees ha-1 were logged). All trees ? 10 cm gbh were inventoried, mapped, girth and crown dimensions measured in fourteen systematically established plots of 20 ? 30 m. In addition, all stems ? 2 m height were inventoried in six 5 ? 5 m subplots. A total of 2,748 trees and saplings were recorded during the first census. All the plots were recensused (except 4 plots, which were recorded as burnt) in 1988 and 1993 for recruitment and mortality. In 1989, a second set of sample plots were established in the unlogged compartment (B; Fig. 1c) to evaluate natural forest dynamics in a similar floristic zone (http://esapubs.org/archive/ecol/E092/115/metadata.htm). Five north-south oriented transects (viz., A, B, C, D and E) of 20 m wide, 180 to 370 m long and 100 m apart from each other were established to inventory trees  ? 10 cm dbh. Collectively they represent a 3.12-ha systematic sample. Subsequently, additional rectangular sampling plots viz., H, R and S, which overlap with sampling area of the transects and represents an additional area of 1.95 ha, were established between 1990 and 1993 to study the forest dynamics according to topography (slope and more or less flat terrain). Totally 3,870 trees were identified, mapped and installed with dendrometric belt (precision of 0.2mm) for growth monitoring. In 2010-11, four 1 ha plots were inventoried in the logged compartment to understand the residual impact of logging. In 2013-2014, the sampling area of the unlogged compartment has been increased to 10 ha The sampling area has been monitored for recruitment and mortality till to date.
