A temperate rainforest is a terrestrial biome with moderate temperatures and high year-round rainfall, found mostly along mild coastal regions, and it's one of the major biomes listed in AP Enviro CED topic 1.2.
A temperate rainforest is a forest biome that gets a ton of rain but stays cool and mild instead of hot. Think of the Pacific Northwest coast, southern Chile, or parts of New Zealand. Heavy ocean moisture plus mountains that trap that moisture create wet conditions all year, while the ocean keeps temperatures from swinging too hard between summer and winter.
In AP Enviro, temperate rainforest is one of the nine major terrestrial biomes you need to know (EK ERT-1.B.2). The big idea from EK ERT-1.B.1 is that a biome's plant and animal communities are shaped by its climate. So the cool, wet, stable conditions here produce dense forests dominated by huge conifers and broadleaf trees, thick layers of moss and ferns, and abundant epiphytes (plants that grow on other plants). The high moisture and mild temps drive a lot of plant growth, which is why these forests store enormous amounts of biomass and are prized for lumber (EK ERT-1.B.3).
This lives in Unit 1: The Living World, topic 1.2 Terrestrial Biomes, and supports learning objective AP Enviro 1.2.A, describing the global distribution and environmental aspects of biomes. The whole point of 1.2 is connecting climate to community: you should be able to look at a temperature and precipitation profile and name the biome. Temperate rainforest is the classic 'cool but very wet' answer. It also matters for resource distribution (EK ERT-1.B.3), since these forests are major lumber sources, which ties biome knowledge to human use later in the course.

Tropical Rainforest (Unit 1)
Both are rainforests with high rainfall, but the temperate version is cool while the tropical version is hot. Same 'lots of water' story, very different temperature, which is exactly the kind of climate-versus-biome distinction the exam wants you to make.
Taiga (Unit 1)
Taiga (boreal forest) is also a cool conifer forest, but it's much drier and has harsh, long winters. Comparing it to temperate rainforest shows how precipitation, not just temperature, separates two forest biomes.
Habitat Fragmentation and Edge Effects (Units 1-2)
When a forest gets cut into patches, the exposed edges dry out and warm up. A moist, stable biome like temperate rainforest shows the most dramatic microclimate shift, which is why it's a great answer for fragmentation questions.
Multiple-choice questions usually ask you to identify a biome from its climate or to pick which example counts as a temperate rainforest. You'll see stems like 'Which of the following is an example of a temperate rainforest biome?' or questions that describe cool temperatures plus high year-round precipitation and ask you to name it. A trickier version asks where fragmentation and edge effects would change microclimate the most, and a wet, stable forest is the strong choice. No released FRQ has used this term verbatim, but biome identification and the climate-to-community link can show up in any prompt about ecosystems or resource distribution.
Both get heavy rain, so people mix them up. The split is temperature: temperate rainforests are cool (mild coastal climates, big conifers, lots of moss), while tropical rainforests are warm year-round (near the equator, highest biodiversity on land). If a question gives you high rainfall, check the temperature to decide which one it is.
A temperate rainforest is a cool, very wet forest biome found mostly along mild coastal regions.
It's one of the nine major terrestrial biomes you need to know for AP Enviro CED topic 1.2 (EK ERT-1.B.2).
Its plant and animal communities, including big conifers, mosses, ferns, and epiphytes, are shaped by its cool, moist climate (EK ERT-1.B.1).
On the exam, identify it by combining high year-round precipitation with moderate (not hot) temperatures.
Because it's moist and stable, it's the biome where forest fragmentation and edge effects change microclimate most dramatically.
It's one of the major terrestrial biomes in CED topic 1.2, defined by moderate temperatures and high rainfall all year, found mainly along mild coastal regions like the Pacific Northwest.
No. Both get heavy rain, but temperate rainforests are cool and located in mild coastal climates, while tropical rainforests are warm year-round and sit near the equator with much higher biodiversity.
Both are cool conifer forests, but taiga (boreal forest) is much drier and has long, harsh winters, while temperate rainforest stays mild and gets high precipitation throughout the year.
Cutting the forest into patches exposes edges that dry out and heat up. Because this biome is normally moist and stable, those edge effects cause especially large microclimate changes, which makes it a common exam answer for fragmentation questions.
Look for a climate profile with high year-round precipitation paired with moderate, not hot, temperatures. That combination, plus features like mosses, ferns, and epiphytes, points to temperate rainforest.
