Little sunlight reaches the floor of coniferous forests because the dense canopy formed by tall, closely spaced conifer trees blocks much of the light. Their needle-like leaves are adapted to capture sunlight efficiently, further limiting the amount that penetrates to the forest floor. Additionally, the thick layer of branches and foliage above creates a shaded environment, resulting in lower light levels for undergrowth and ground-dwelling plants.
