c3_plant_functional_typesA plant that utilizes the C3 carbon fixation pathway as the sole mechanism to bind CO2 before photosynthesis reactions take place. All trees are C3 type. Grasses and crops can be C3 or C4.
c4_plant_functional_typesA plant that utilizes the C4 carbon fixation pathway in which the CO2 is first bound to a compound containing four carbon atoms before photosynthesis reactions take place. All trees are C3 type. Grasses and crops can be C3 or C4.

primary_deciduous_treesA primary forest is a naturally regenerated forest of native species, where there are no clearly visible indications of human activities and the ecological processes are not significantly disturbed. Reference: 'Global Forest Resources Assessment: Terms and Definitions', Forestry Department of Food and Agriculture Organization (FAO) of the United Nations, Rome 2010, www.fao.org/forestry/14241-0d7b74f45b0d2cfef31599cc17e4c28cd.pdf. Deciduous trees lose their leaves seasonally, for example, during winter in high latitudes or following seasonal variations in rainfall.
