Modelling composition and performance of timber tree
regeneration after selective logging
|
|
| Objective: |
| Selection of trees for felling
and retention as seed trees, combined with the distribution
and intensity of extraction disturbance are variables, which
have a major influence on the composition and distribution of
tree regeneration. They are also variables, which management
and logging practice can influence. Implicit in Ghana’s
current Girth Limit Selection system is an expectation that
logging disturbance will permit and may even enhance the regeneration
of timber tree species for future harvest. But tree selection
and retention are largely based on market and milling demands.
Current harvesting guidelines focus on a balanced selection
of trees for felling with consideration of advance regeneration.
These guidelines are disconnected from seedling regeneration
requirements. This project will link existing survey data on
the composition of timber tree regeneration to seed sources
and to canopy and soil. |
| Output: |
|
Concrete outputs are expected to be:
- A model to predict the composition of timber tree regeneration
in semi-natural forest following selective logging. The
predictions will include spatially explicit estimates of
the probabilities for the successful establishment of timber
tree species in different parts of the exploited forest;
- Guidelines for improvement of silvicultural interventions;
- Training of a Ghanaian post-graduate.
