Conservation in Indonesia encompasses efforts to protect the country's unique environment and biodiversity. Indonesia harbours a high rate of endemism and is rich in tropical rainforest and coral reefs.
Traditional forest garden practices have played a role in preserving biodiversity in Indonesia. Formal conservation efforts began in the 19th century during Dutch colonial rule. Following independence, Indonesian conservation has been implemented by the Indonesian government along with grassroots efforts from non-governmental organisations and the cooperation of religious leaders. Indonesia has gazetted 21.3% of its land and 9% of its maritime area as protected areas, with targets to increase these. Implementation of conservation in the country is hampered by deforestation and mining.
