Temperate coniferous forest
A forest biome in temperate regions dominated by conifers, often evergreen needle-leaved trees, and shaped by distinct seasonal climates.
Conifer: A cone-bearing seed plant, usually with needle-like or scale-like leaves. Conifers dominate this biome, though their species and growth forms vary by region.
Pacific temperate rainforests: Moist temperate forests along the Pacific coast of North America, with large conifers and abundant precipitation. They exemplify the wet, highly productive end of temperate coniferous forests.
Wildfire: An uncontrolled fire that burns vegetation and organic matter in a natural landscape. Fire can open conifer cones, clear competing vegetation, and reset forest succession.
Tongass National Forest: A large national forest in southeastern Alaska, encompassing extensive temperate rainforest. Its cool, wet coastal forests are among the largest temperate conifer systems.
Bark beetle: A beetle that breeds beneath tree bark, with some species killing living conifers. Outbreaks can transform conifer stands, especially when drought weakens trees.
Temperate climate: A climate regime with moderate temperatures and seasonal variation, between tropical and polar extremes. Seasonal temperature patterns distinguish these forests from tropical and boreal biomes.
Temperate rain forest: A forest in a temperate climate receiving high rainfall, often with lush understory growth. Some temperate coniferous forests become rain forests where oceanic moisture is abundant.
Forest succession: The directional change in a forest’s species composition and structure over time. Succession explains how disturbed stands develop into mature conifer forests.
Olympic National Park: A protected area in Washington State containing mountains, temperate rainforest, and Pacific coastline. Its west-facing slopes support exceptionally wet conifer forest communities.
Forest fragmentation: The division of continuous forest into smaller, isolated patches. Roads and land conversion can isolate habitat and alter forest-edge conditions.
