Loch of Lintrathen is a mid-altitude oligotrophic-mesotrophic loch, which supports large numbers of birds. There are internationally important numbers of greylag geese, with 3% of the Iceland population over-wintering at the site. Other wildlife includes whooper swans, otters and osprey, and the loch is used for trout fishing. The fishing is managed by the Lintrathen Angling Club and both brown and rainbow trout are fished for.
