Threats to Genetic Viability of Southeast Asian Forest Species

  • Ratnam Wickneswari
Part of the Advances in Asian Human-Environmental Research book series (AAHER, volume 2)


The major threat to genetic viability of the Southeast Asian forest species is commercial logging and fragmentation being largely due to infrastructural development and agricultural activities. Species vulnerability to the threat of genetic viability posed by commercial logging is highly correlated with its abundance in a particular forest management unit. Tree density for the species can be a useful indicator in reflecting the risk of genetic viability rather than the overall disturbance level based on reduction in basal area of all trees. Reproductive success of mature trees together with successful regeneration of seedlings and saplings in disturbed forests is an important determinant of genetic viability of species. Knowledge of the biological attributes of species including their local evolution can be used to develop field guides in harvesting operations to ensure the genetic quality of residuals left behind in the post-harvest stands.
