Chile has a native forest that constitutes 18 percent of its continental surface area and over 60 million hectares of protected areas. The country is considered a global hotspot of conservation priority due to its endemism and a high degree of habitat loss. The loss of ecosystems could increase if economic development does not progressively adopt sustainability standards that create less of an impact on biodiversity. From August 2015 to May 2020, FAO implemented the project in order "to develop and implement an integrated monitoring and assessment system on carbon stocks and biodiversity in forest ecosystems (SIMEF) supporting the National Greenhouse Gases Inventory (INGEI) and the design of policies, regulations and SFM practices incorporating the REDD+ Programme and biodiversity conservation in forest ecosystems". The project established sound foundations that improve the monitoring of the conditions of forest ecosystems and, consequently, more robust information is generated and with greater frequency. It is worth highlighting the creation of an interinstitutional structure that will support the continuity of the SIMEF and the creation of a digital platform with five tools. The SIMEF is, at present, a regular programme of the Chilean State with a governance system and with a permanent annual budget. Given this, the sustainability of the achievements made in the project can be maintained and strengthened. However, a low level of appropriation of the system at local level was identified, which could affect its sustainability. -

Sampling Design Options for 2nd Biophysical Inventory (NAFORMA II)
2022Also available in:
No results found.Three options for the sampling design of the field plot clusters of NAFORMA II biophysical survey are compared in this report. Option 1 consists of re-measuring all NAFORMA I field sample plots (3 205 clusters) and Option 2 of re-measuring only those that were established as permanent (848 clusters). The recommended Option 3 is a compromise between these two “extreme” options: Re-measure a subset (1 405 clusters) of NAFORMA I field sample plots including (almost) all permanent clusters and a carefully selected set of other NAFORMA I field plot clusters to obtain a uniform sample within each TFS zone. Design Option 3 has the following features: • Sampling intensity is uniform within each TFS zone. This makes it simple to use the data. For example, mean volumes can be estimated by averages over the plots. • The selected clusters are well-spread over the target population. • The anticipated precision of land-class area and mean wood volume relative to sample size is nearly as good as that of NAFORMA I. • All proposed clusters were measured in NAFORMA I, which enables precise estimation of change based on repeated measurements. The costs and precision were anticipated by utilizing NAFORMA I field data, information about subsequent improvements in the road network, and changes in land-use using satellite imaging derived land-class maps.
