Scottish Natural Heritage is the statutory body responsible for natural heritage management in Scotland. One of its duties is to establish national nature reserves (NNR)s. Until 2004 there were 73, but a review carried out in that year resulted in a significant number of sites losing their NNR status, and by 2006 there were 55. there are 43. Forestry and Land Scotland serves as the forestry department of the Scottish Government and is one of the country's largest landowners. The Joint Nature Conservation Committee is the statutory adviser to Government on UK and international nature conservation.
