The area of forest and other wooded land has increased to 27.2% of the national territory. Afforestation efforts, partly to combat soil erosion, have reached 250, 350 and 400 million planted seedlings respectively in 2005, 2006 and 2007, a major contribution to the UNEP goal of at least 1 billion tree planting worldwide each year. Legislation concerning biodiversity has improved, as have related institutional cooperation and co-ordination. The total extent of protected areas has increased during the review period and now accounts for 5.3% of Turkey’s total land area. Turkey has further strengthened the protection of these areas through management plans.
