Forest gardening is a woodland ecosystem that requires little maintenance. Forest gardening is a form of intercropping that is a seven tier, layering system utilizing the space from the sub-ground up to the canopy in order to provide high yielding food production for human consumption in wooded areas. Layering utilizes the photosynthesis to the maximum benefit for each tier within the forest garden. The canopy level consists of the tallest fruit/nut trees with dwarf trees in the...
Rainforests are forests that are characterized by high levels of rainfall, with definitions based on a minimum usual annual rainfall of about 68 to 78 inches. The monsoon trough, or otherwise known as the intertropical convergence zone, holds an important role in producing the climatic conditions that are essential for the Earth’s tropical rainforests. About 40 to 75 percent of all biotic species are native to the rainforests. It’s been estimated that there might be many millions of...
