WHY IS THE ASSESSMENT BEING CARRIED OUT? MAIN AIMS There are many reasons for carrying out a forest quality assessment, for instance: • • • • • • • • • • designing a protected areas system; planning extractive reserves; improving a suburban recreational area; resolving conflicts between conservationists and small forest owners; negotiating a concession for timber or non-timber products; developing an ecoregional conservation plan; developing a monitoring and evaluation system; monitoring progress towards forest landscape restoration or sustainable forest management; identifying high conservation value forests (Jennings et al, 2003); as part of an advocacy process to make a case for conservation or development.
This is not a complete list of possibilities but a skeleton that can be supplemented or replaced by alternatives as desired. 3 A draft list of standard indicators for a forest quality assessment Indicators of authenticity Composition Composition of species, ecosystems and genetic variation Pattern Spatial variation of trees with respect to age, size etc. Function Continuity, proportion and type of dead timber etc. Process Disturbance patterns, life cycles Resilience Tree health, ecosystem health, ability to tolerate environmental stress Continuity Area, degree of fragmentation and age Development patterns Management choices and other pressures Indicators of environmental benefits Biodiversity conservation Of ecosystems, species and genetic variation Soil and watershed protection Reducing erosion, maintaining fisheries, controlling flooding Impacts on other ecosystems Such as freshwater and coastal zones and through afforestation Climate stabilization Transpiration, regulation of climatic extremes, carbon sequestration Indicators of social and economic benefits Wood products Fuelwood, charcoal, timber, pulp, paper, reconstituted fibres Non-wood products Food, oils, medicines, aromatics, resins, dyes, building materials etc.
WHERE DOES THE ASSESSMENT TAKE PLACE? LOCATION The location should be determined by the assessment team and if appropriate also by other participants (and the eventual choice may in turn affect the choice of participants). Boundaries can be drawn along biological, geographical, political, economic or social lines. An official or unofficial management unit will often be the basis of assessment, but edge effects are important – it will often be necessary to extend the assessment beyond economic or political boundaries to reflect real human and/or biological values.
