Temperate rainforests are unique ecosystems found in coastal regions with mild temperatures and high rainfall. They typically experience at least 30 to 60 inches of precipitation annually, which supports a diverse range of plant and animal life. Common trees in these forests include Douglas fir, redwood, and western hemlock, which can grow to impressive heights. These forests are characterized by their lush undergrowth, including ferns and mosses, which thrive in the moist environment. Temperate rainforests play a crucial role in carbon storage and provide habitat for various species, such as the spotted owl and black bear, contributing to biodiversity and ecological balance.
