metsänäkyvyys
Metsänäkyvyys, meaning "forest visibility" in Finnish, refers to the extent to which the forest canopy allows sunlight to penetrate to the forest floor. It is a crucial factor influencing the growth and composition of understory vegetation. High metsänäkyvyys, characterized by a sparse canopy or large gaps, allows more light to reach the ground, favoring sun-loving plants and seedlings. Conversely, low metsänäkyvyys, resulting from a dense canopy, creates a shaded environment that supports shade-tolerant species and can limit regeneration for some tree types.
The level of metsänäkyvyys is determined by several forest characteristics, including tree species, stand density, age,
