Forest rings are large, circular patterns of low tree density in the boreal forests of northern Canada. These rings can range from 50 metres (160 ft) to nearly 2 kilometres (1.2 mi) in diameter, with rims about 20 metres (66 ft) in thickness. The origin of forest rings is not known, despite several mechanisms for their creation having been proposed. Such hypotheses include radially growing fungus, buried kimberlite pipes, trapped gas pockets, and meteorite impact craters.

- Cincin hutan atau lingkaran hutan adalah pola melingkar yang besar dengan kerapatan pohon yang rendah di hutan boreal Kanada bagian utara. Diameter cincin ini dapat berkisar dari 50 meter (160 kaki) hingga hampir 2 kilometer (1,2 mil), dengan keliling atau ketebalan sekitar 20 meter (66 kaki). Asal muasal cincin hutan belum diketahui hingga kini, beberapa mekanisme pembentukan cincin ini telah diusulkan. Beberapa hipotesis tersebut termasuk jamur yang tumbuh secara radial, pipa kimberlite yang terkubur, kantong gas yang terperangkap, dan kawah meteorit. Cincin hutan juga telah dilaporkan penampakannya di hutan Rusia dan Australia. (in)
