Põhja-Kõrvemaa Nature Reserve

Põhja-Kõrvemaa Nature Reserve (Estonian: Põhja-Kõrvemaa looduskaitseala) is a protected area in Harju County, Northern Estonia, some 50 km east of Tallinn. With an area of 130.9 km², it is the third largest nature reserve in Estonia. Dominated by forests and bogs, it aims to protect rare and endangered species, their habitats, and valuable natural landscapes.

Põhja-Kõrvemaa (meaning North Kõrvemaa) occupies the northern part of Kõrvemaa, which itself forms the northern part of Transitional Estonia, a large forested and sparsely populated area spanning in northeast–southwest direction through Estonia, from Lahemaa through Soomaa to Latvia.
