Genetic Diversity in Reforestation

This document provides a comprehensive overview of genetic diversity's critical role in reforestation efforts. It details objectives such as producing fast-growing species for timber and ecological functions like conservation and protection. We explore site conditions, reforestation techniques, and species selection based on ecological needs and adaptability. Emphasis is placed on matching species to specific site characteristics, along with diagrams depicting strategies for various degradation levels. Additionally, the involvement of local communities, such as Orang Asli in Sabah, highlights the integration of socio-economic factors in rehabilitation projects.

Presentation Transcript

  1. Genetic Diversity in Reforestation

  2. Contents • Objectives • Site condition • Reforestation techniques • Species selection

  3. Ecological Needs in Rehabilitation • System - based on site  topography, soil, micro-climate - extent of damage & natural recovery? • Species - adaptability  survive? grow? - growth rate - eco-physiological needs of the species - species-site matching

  4. Techniques OBJECTIVES Open Partial shade Fully shaded Diversity species

  5. Detailed Diagrams

  6. Heavily Degraded Intensive Erosion control Soil amelioration Canopy cover? OPEN Less Intensive Direct planting Medium Degradation

  7. Light Degradation Less Intensive Line Direct planting Cluster Gap PARTIAL SHADE Medium Degradation Back to Top

  8. Objectives 1. Production (plantation – forest yield) - to supply raw material - fast growing species 2. Production (ecological functions) - protection, conservation and amenity - mix spp with mixed growth rates

  9. Timber Back to Top Non-Timber International National
