This definition would not suit the forests of western North America, and so the term "temperate rainforest" is not so widely agreed. The weather in a rainforest would be humid, which is wet but warm like a greenhouse. The bottom most layer receives 2% of the sunlight. Only plants adapted to low light can grow in this region. The understory layer lies between the canopy and forest floor. It is a home to a number of birds, snakes and lizards as well as predators such as jaguars and leopards. The leaves are much bigger at this level and insect life is abundant.
