It is established to protect the Nigula Bog and its surrounding forests in their natural state.

The farmlands that generate a buffer-zone around the bog and forests are managed extensively.

The reserve is also an important habitat for large carnivores (brown bear, wolf, lynx) and big game animals (moose, roe deer, red deer, wild boar etc.).

New protection rules, that added the surrounding forests and farmlands to the nature reserve were fixed in 1979.

Nigula Nature Reserve Administration [3] is an organisation that manages Nigula and Sookuninga Nature Reserves that are situated in South-West of Estonia on the Border of Estonia and Latvia.
