ECOLOGY AND SUSTAINABLE SEMI-NATURAL MANAGEMENT

OF INDIGENOUS FORESTS IN CENTRAL SOUTH-EAST ASIA

Objectives

The main objectives of the project are :

F
To provide information on the autecology and dynamics of indigenous forest types at different degree of disturbance.

F
To synthesise and model ecological processes and semi-natural silvicultural management options for natural and disturbed forest.

F
To analyse the anthropogenic impact on forest ecosystems and assess the socio-economic implications of management options.

F
To provide information necessary for the development of sustainable semi-natural silvicultural management methods suited to accelerate plant successions, forest rehabilitation and forest productivity, particularly in buffer zone management.

Activities

The key activities envisaged are :

*
Based on the interpretation of a chrono-sequence of aerial photographs at different scales the forest will be classified into stands, on basis of their composition, associated ground vegetation, and the maturity, density, distribution and condition of the remaining trees.

*
On the basis of the above stand classification, a field inventory will be conducted on the structure, composition and dynamics of the stands. Parallel to this soil fertility conditions and macro- and micro-climatic data will be gathered and correlated to stand conditions.

*
Observation and experimentation into regeneration and establishment will initially focus at the quantitative and qualitative assessment of natural seed production and dispersal, seed viability, and germination rates under experimental and natural conditions. It will be followed by experimentally studying the influence of site-preparation on germination rates and seedling establishment.

*
In silvicultural improvement experiments, DBH-crown diameter correlations and social position of trees will be utilised for selection of future-trees and the planning of thinnings. The natural growth of the different stands will be calculated and compared with the actual growth performance under different tending regimes. A GIS-based approach will be applied to analyse the effect of site conditions on fire frequency.

*
An analysis of the economic viability and the agricultural potential of the sites (including non-forest products) will be conducted parallel to the forest classification and evaluation process.

Expected outcome

The project will provide information on the structure and dynamics of deciduous secondary forests in the region, summarised in species monographs and forest-type descriptions. The findings will be integrated into an index-based, descriptive model to assess fructification, regeneration and seedling establishment with respect to forming stable stands. A predictive, flow-chart-based decision support tool will be developed to facilitate silvicultural decision-making toward semi-natural forest management, particulary useful in the management of the buffer zone surrounding the study area. Through direct co-operation with local research institutions and the Thai forest administration a direct extension effect will be achieved with respect to the methodological approach and the results.
