For [[forests]], [[Canopy (biology)|canopy]] refers to the upper layer or [[habitat]] zone, formed by mature [[Crown (botany)|tree crowns]] and including other biological organisms ([[epiphytes]], [[lianas]], arboreal animals, etc.). The canopy level is the third level of the temperate rainforest. The trees forming the canopy, [[conifers]], can stand as tall as 100 metres or more. A variety of species survive in the canopy. The tops of these trees collect most of the rain, moisture, and photosynthesis that the [[rainforest]] takes in. They form a canopy over the forest, covering about 95% of the floor during the summer.

The canopy's coverage affects the [[shade tolerance]] levels of forest floor plants. When the canopy is in full bloom, covering about 95% of the floor, plant survival decreases. Some plant species have become shade tolerant in order to survive. 
The treetops take in the heavy amount of rain and keep the lower levels of the forest damp.

The canopy survives through [[photosynthesis]]. The leaves provide energy and nutrients for the trees, which provide homes and food for the forest. Through satellite data, the radiation use efficiency (RUE) calculates the annual amount of photosynthesis that occurs in temperate rainforests. A diverse amount of photosynthesis occurs based on the location and [[microclimate]]s of the forest.<ref>{{Cite web |last=Stein |first=Rebekah |date=2024-03-11 |title=Why do trees need sunlight?
