Document Summary

In order to grow a forest: temperature- some trees are cold adapted, and some are not, air (carbon hydrogen, oxygen, nitrogen)- the need of clean air is required for trees, light (photosynthesis, water, soil. Forests create, store and mobilize nutrients and water. They are living just like humans: photosynthesis, mycorrhizal associations, soil interactions, nutrients, transpiration stream. In the presence of light and energy, we have a carbon capture which is converted into glucose, which is converted into other chemicals through water. Mycorrhizae: they are specific type of fungi that form associations with plants. In return, the fungus gets carbon compounds: fungi cannot photosynthesis, but they get benefit by providing this surface increase by getting carbon compounds, ectomycorrhizae: fungus forms a sheath around root. It affects the water flow in the specific area, and a huge change in temperature regulation etc. Mature forests are complex ecosystems because they create microclimates and microenvironments for the plants underneath them.
