GIS/RS Based Survey Techniques for Community Forest (CF) Boundary Delineation and Allocation of Pilot Sample Plots Survey/field visit for the verification of satellite imagery, to interact with the local forest communities and data collection is an essential for analyze and further processing of GIS/RS data. To get the overall idea and initial data collection in three watersheds Kayer Khola in Chitawan District, Ludi Khola in Gorkha District and Charnawati in Dolakha District of Nepal under Reducing Emissions from Deforestation and Forest Degradation (REDD) pilot project was done. By using the high resolution GeoEye 1 satellite imagery with ancillary information A0 paper size field maps were prepared for the delineation of Community Forest User Groups (CFUGs) boundaries. Participatory approach was adopted for the delineation of CFUGs. Conflicted areas during the delineation were resolved to make the tracks and area calculation along the community forest. Delineated community forest areas were digitized and calculated areas were compared with the already compass based calculated areas. Forest canopy (Dense & Sparse) and aspect were two criteria’s for identification of pilot sample plots. 10 X 10 sample plots were taken for the measurement of tree diameters and coordinates. The collected coordinates were also used for the preparation of land cover mapping. Differential Global Positioning System (DGPS) receiver was used for the accuracy assessment and to collect the data for sample plots.
