1) Creating grid cell size of 300 km2 covering entire the landscape consecutive from Thung Yai-Huai Kha Khaeng World Heritage Site based on minimum size of Elephant’s home range (Sukumar, 1989) and grid cell size for South East Asian sites of TIGER FOREVER landscape.
2) Dividing each grid cell size of 300 km2 into 16 sub-grid cells of equal size (18.75 km2 ).
3) ) Eliminating sub- grids covering less than 50 % of large and medium sized mammals and hornbills and adjacent to the National border.
4) Determining scope of study areas by excluding upper part of SINP and lower part of MPWS from the intensive survey because of limitation on time, budget, and man power.
5) Selecting sub grids with most likely places for wildlife habitat based on 22 visited sites during preliminary survey.
6) Setting up the minimum distance in each sub grid at 2 km due to problems on small forest patch size, geographical restriction and risk of land mines. However, longer distance has been used in the larger patch sizes especially in 3 protected areas.
7) Standardizing index count on occupancy of landscape species and threats by dividing a transect route into intervals of 100- meter segment. In other word, the evidences of same spe- cies found interval 100 meters will be counted only one time.
8) Conducting intensive survey twice a year in wet (May – November 2007) and dry sea- son (December 2007– May 2008) because of assumption on variation of wildlife movement is different between wet season and dry season.
9) Recording target landscape species, ecological factors, and threats in select sub grids and mark positions using GPS.
10) Fill in all relevant data into 6 CEP-BCI Tenasserim data forms.
11) Verify field data by WCS staffs before input to database and GIS applications.
