Forest cover (Government reported)
This indicator shows the trend in forest cover for the years 1980-2007, as well as the average annual percent change of forest cover during 2000-2007, derived from government reports (ASEAN Biodiversity Outlook 2010). The percentages of annual change in forest cover were calculated using the forest cover in the year 2000 as a baseline. “Forest cover” is defined by each nation’s government individually.
By 2020, the rate of loss of all natural habitats, including forests, is at least halved and where feasible brought close to zero, and degradation and fragmentation is significantly reduced.
The percent change of forest cover ranges from -100% to 100%. Higher absolute values indicate faster change in forest cover, with values less than 0 indicating net forest loss, and values greater than 0 indicating net forest gain. The forest cover baseline ranges from 0-100%, with higher value indicating that a greater percentage of a country’s land surface is covered by forest. Low percent cover can be a result of past deforestation or due to the existence of natural non-forest ecosystems such as wetlands, shrublands or grasslands.
This indicator is available at the country scale for the Lower Mekong region.
The percent of forest cover is available for 1980, 1990, 2000 and 2007 as baselines.
The average percent change of forest cover is available annually for the years 2000-2007.
The forest cover (government reported) indicator is derived from the forested area of the ASEAN region in 1980-2007 provided by the ASEAN Biodiversity Outlook (ASEAN Centre for Biodiversity, 2010), which compiled information by ASEAN member states on land area, forest area (1980, 1990, 2000 and 2007), and annual rate of change (2000-2007).
This indicator shows the net change of forest cover at the country level, as a combined effect of deforestation and afforestation. The indicator does not provide individual values for forest loss or gain separately.
Unlike the forest cover indicator derived from a global dataset (Hansen et al, 2013) where forest cover was defined as areas with at least 25% tree cover, the definition of forest reported by governments for this indicator varies among countries.
