At east end eden, trees represent the long term stability of the farm ecosystem. These trees have been selected and planted with 4 main considerations: yield, productive life span, hardiness, and their interactions with other species. Often their yields represent large harvests of dense Carbohydrates, Oils and Proteins in the form Pods, Nuts, and Fruits while also offering timber, livestock fodder, mulch and precious shade. Trees are placed in a ‘polyculture” or an assembly of multiple mutually beneficial species. This increases productivity by allowing for multiple yields to occur simultaneously in less land area, reduces inputs, and the need for constant human management. Trees grow well together and resilient, largely self maintained forests of food, fuel, fibre, medicine and timber are quite possible and a very stable long term resource base for humanity.
