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 accumulating literature over the past two decades on the rates of tropical tree growth, mortality and recruitment showed significant changes in the structure and function of mature tropical forests by the close of the twentieth century. Notably tree turnover rates (Phillips 1996) and growth rates in the tropical forests have accelerated over the past decades (Laurence et al., 2004), which are consistent with the hypothesis of increased productivity caused by the rising concentrations CO2 (Lewis 2006). Contrastingly, Feely et al. (2007) documented decelerating growth rates of tropical tree species over the past two decades in the 50 ha forest dynamic plots in Panama and Malaysia. 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.

The principal objectives were

  1. to gather baseline information on tree diversity in a logged forest and monitor post-logging forest dynamics,
  2. to assess tree diversity in a unlogged forest and monitor the natural forest dynamics,
  3. to compare the demographic processes across spatio-temporal scales in logged and unlogged forests,
  4. to describe the growth strategies of tree species according to their position at the adult stage in the canopy such as understorey, low-canopy, canopy or emergent species,
  5. to elucidate and modeling the ecological processes that may interact upon the distribution, abundance and growth of species across spatio-temporal scales in order to draw insights on diversity and coexistence of species in tropical forests,

to estimate the above ground biomass of tropical evergreen forest

Materials and methods:

The study area, 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.


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 ³ 10 cm gbh were inventoried, mapped, girth and crown dimensions measured in fourteen systematically established plots of 20 ´ 30 m. In addition, all stems ³ 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  ³ 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. The sampling area has been monitored for recruitment and mortality till to date.


Impact of logging on tree diversity: The logged compartment (A) had 347 trees and 54 species in 0.6 ha (1986) whereas the unlogged compartment (B) had 1891 trees and 88 species in 3.12 ha (1990). Initial stand density and basal area of the trees were slightly lower in the logged forest (578 stems ha-1; 34.8 m2 ha-1) than in the unlogged forest (606 stems ha-1; 39.3 m2 ha-1). Mean density and basal area for the 20 ´ 30 m samples of the two compartments (A and B) displayed no significant difference (t-tests, P>0.25). The expected number of species based on the rarefaction of both the compartments displayed almost similar trend (Fig 2a). An analysis of the growth of trees revealed that most of the trees had low girth increments (Fig. 2b).The mortality rate was more or less similar for the compartments (0.89% for A and 0.87% for B), which is lower than the rates observed in other tropical forests. Fig 2c and 2d depicts the mortality and recruitment rates of the two compartments. The impact of selective felling, 10 to 15 years after the harvest, revealed that those trees with girth of > 40 cm dbh belonging to lower and intermediate storey species had 4 times higher mortality in the logged compartment. Despite the general trend of a reduction in the difference between the density and the basal area of the two compartments, medium-term modification of the demographic processes among the various structural ensembles in the logged compartment, indicates that selective felling may not be sustainable in the long-term without consequences on the forest structure and composition.

Structure, composition and dynamics of unlogged forest:

The major finding are:
A total of 100 species with a mean tree density of 661 trees ha-1 and basal area of 43 m2 ha-1 were recorded. Just four species (viz., Dipterocarpus indicus, Humboldtia brunonis, Myristica dactyloides and Vateria indica) occupy four different storeys of the forest and dominate the forest stand in terms of density and basal area (collectively they account for greater than 50% of density and basal area; Fig 3a). Tree demography showed a decreasing trend immediately after establishment of the sampling plots and later it showed an ascending trend (Fig. 3b).  A model was proposed to predict the diameter increment in relation to the crown position using Dawkins crown position score (based on the indices of tree vigour, tree social status, local density and explicit spatial competition included) for the light demanding evergreen species Vateria indica (Fig. 3c). Diameter growth varied according to slope intensity and to tree size: the growth of large trees was clearly higher on steep slopes whereas the growth of small trees proved lower or similar (Fig. 3d). On the contrary, tree heights differed according to slope intensity: for a given diameter, trees were taller on gentle slopes than on steep slopes. The observed changes between gentle and steep slopes suggest differences at the tree level through a modification of its shape, but also differences in the major processes responsible for stand dynamics: competition, establishment and survival. Investigation on the growth strategies of the five dominant species showed significant differences concerning demographic parameters, mean and potential radial growth, differential allocation of biomass among tree parts, morphological plasticity and both supra-annual and seasonal rhythms of radial growth. Besides, the analyses showed a high intraspecific variability in radial growth, differential allocation of biomass between the different parts of a tree, and rhythms of radial growth. The results open new prospects for modelling the dynamics of forest tree communities, especially for a simulation-based exploration of how growth strategies contribute to species coexistence

Future plan:

The thorough monitoring of these plots is already an invaluable source of knowledge and understanding about the natural dynamics of the Western Ghats evergreen forests. The accuracy and reliability of the diameter measurements combined with the number of equipped trees make this dataset more or less unique in the tropics. The monitoring effort is obviously worth prolonging on a long-term basis in order to integrate the Uppangala Permanent Sample Plot (PSP) within the global networks of permanent plots. Such an effort is only conceivable as part of a close, long-lasting collaboration between KFD and FIP.  From the standpoint of fieldwork, an urgent need is to rationalize the sampling design, by extending the XY mapping of the trees over a rectangular large plots of about 10 ha, which will integrate most of the existing sampling transects and plots. This will also increase the potential uses of the PSP, for instance, studies such as analyses of spatial patterns of tree size classes and/or species.
