It has four main strategic thrusts: knowledge management, valuation of biodiversity, conservation, and diversification of use. Some of the more specific and tangible biodiversity and forestry goals and targets include: expanding protected areas to 16% by 2020 from 12.9% today, significantly reducing (also by 2020) the national forest degradation rate and maintaining forest biodiversity under the REDD+ programme on greenhouse gas emissions from deforestation and degradation, and, by 2020, having efficient prevention, detection and early response systems and instruments in place so as to prevent, mitigate, control and eradicate invasive species. A major effort currently under way is to decentralise implementation through the development of state biodiversity strategies.
