Document Summary
25% of the world"s forests are in canada. Soil (n, p, k, c, mg, s) (fe, mn, b, zm cu, mb, c) Forest"s create, store, and mobilize nutrients and water. Soils supply water and nutrients to trees. To transport water, water must be lost. To move water up, suction must be created, and a vacuum must be created by opening and closing the stomata. Plant gets increased surface area for nutrient absorption; fungus gets carbohydrates. Fungus forms a sheath around the root. Animals are important in dispersing fungal spores in many forest ecosystem. Provide habitat, maintain soil, air, and water quality, and play key roles in biogeochemical systems. Crucial link in nutrient and water cycles. Softwood = timber harvested from coniferous trees. Hardwood = timber harvested from deciduous trees. Ntfps = non-timber forest products, such as medicinal, herbal, decorative, and edible products. Forest"s are home to 300 million people. Over 1. 5 billion people depend on forests for their livelihoods.
