The study was carried out in Traditional Agroforestry systems in different parts of Garhwal Himalaya, India during 2012-13 with varying altitudinal ranges (1000 to 1500m, 1500 to 2000m and 2000 to 2500m asl) comprising northern and southern aspects to assess the change in various tree crop combination and their utilization for the rural development and need of local people.

The major traditional agroforestry systems viz. agrisilviculture (AS), agrisilvihorticulture (ASH) and agrihorticulture (AH) systems were studied with reference to change in elevation and aspects. The tree-crop combinations adopted on the different study sites were dependent on the climatic and geographical situations and accordingly these combinations are used by the local people for their livelihood. During the study the very common and important agroforestry trees as Grewia optiva, Celtis australis and Melia azedarach usually present with agricultural crops as Triticum aestivum, Zea mays, Eleusine coracana, Echinochloa frumentacea, Amaranthus caudatus, Phaseolus vulgaris etc in the elevation ranging 1000 to 1500m. In the middle Himalayan region (1500-2000m) the common tree species as Quercus leucotrichophora, Grewia optiva, Celtis australis, , Prunus armeniaca (fruit tree) present with agricultural crops like Triticum aestivum, Eleusine coracana, Amaranthus caudatus, Phaseolus vulgaris, Solanum tuberosum etc. In the elevation 2000 to 2500m the agroforestry tree species like Quercus leucotrichophora, Quercus floribunda, Quercus semicarpifolia, Juglans regia, Malus domestica (fruit tree) forms the basic combination with agricultural crops as Solanum tuberosum, Pisum sativum, Amaramthus caudatus, Phaseolus vulgaris.

The farmers of the study area showed close relationship between the traditional agroforestry systems and their daily domestic requirements for fuel, fodder, fibre and fruits, however, the change in altitude and aspects play major role in availability of these multifarious benefits from existing agroforestry systems.
