The emphasis of forest migration is placed on the movement of the populations that make up the forest community.

A study on forest transition theory reported that over 60 years (1960–2019), "the global forest area has declined by 81.7 million ha", and concluded higher income nations need to reduce imports of tropical forest-related products and help with theoretically forest-related socioeconomic development and international policies.

With the turmoil of the Migration Period, the forest spread into Central Europe again. In areas cultivated during Roman colonization, the forest often regained a foothold.

Illumination’s “Migration” — about a fussy duck dad who reluctantly reconsiders his fear of flying — is a cartoon in search of a concept, where the most daring idea is hiring the Oscar ...
Circadian migration is where birds utilise circadian rhythm (CR) to regulate migration in both fall and spring. In circadian migration, clocks of both circadian (daily) and circannual (annual) patterns are used to determine the birds' orientation in both time and space as they migrate from one destination to the next.
