The emphasis of forest migration is placed on the movement of the populations that make up the forest community. Though an individual tree is permanently fixed in a location, tree populations may migrate over the landscape through successful dispersal and establishment into new regions and/or a lack of regeneration in a portion of its previous ...
A 2011 discussion paper in the British Columbia Journal of Ecosystems and Management offered this definition of assisted migration: "the purposeful movement of species to facilitate or mimic natural population or range expansion to help ensure forest plantations remain resilient in future climates."
The migratory woodland caribou refers to two herds of Rangifer tarandus (known as caribou in North America) that are included in the migratory woodland ecotype of the subspecies Rangifer tarandus caribou or woodland caribou [1] [2] that live in Nunavik, Quebec, and Labrador: the Leaf River caribou herd (LRCH) [3] [4] and the George River caribou herd (GRCH) south of Ungava Bay.
Epilobium hirsutum seed head dispersing seeds. In spermatophyte plants, seed dispersal is the movement, spread or transport of seeds away from the parent plant. [1] Plants have limited mobility and rely upon a variety of dispersal vectors to transport their seeds, including both abiotic vectors, such as the wind, and living vectors such as birds.
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.

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.
It is a simple relationship between a host (the forest), an agent (the beetle) and the environment (the weather and temperature). [89] However, as climate change causes mountain areas to become warmer and drier, pine beetles have more power to infest and destroy the forest ecosystems, such as the whitebark pine forests of the Rocky Mountains.
