Ntfps = non-timber forest products, such as medicinal, herbal, decorative, and edible o o products. Flora: cold-tolerant evergreen conifers with needle-like leaves (pine, fir, spruce) Only ~9% of land, but >50% of species. <1% nutrients penetrate >5cm; most nutrients are in biota. Unlike in other biomes, most mammal herbivores are arboreal in these forests: Since most primary production is in canopy, most species are canopy specialists. Mid-latitude forests in europe, eastern china, eastern north america. Deciduous trees lose their leaves each fall and remain dormant during winter. Canopy: allows some light to penetrate; well- developed understory. 1993: the largest act of civil disobedience in canadian history. The science panel for sustainable forest practices in clayoquot sound formed in 1993. Phase out clear-cutting conserve old-growth selective logging to preserve forest habitats and streams. Develop non-timber sources of revenue (tourism, other forest products, carbon offsets) Clearing forest for farming was one of the first human environmental impacts.
