They suffered kosses because they are not concerned about providing right habitat and environment factors before building their EBN swiftlet house. This study aimed to identify the list of habitat and environment factors of EBN swiftlet ranching and to established the habitat and environment factors as success factors of swiftlet ranching. This study comprised of interview question and field study. Questionnaires were distributed 100 players in EBN industry in Terengganu from February 2012 untill October 2013. For the field study, air and surface temperatures, relatives humidity, light intensity and sound level were recorded in nine EBN swiftlet houses in three different areas, the forested, the coastal and the town areas. From the questionnaires we found that the most popular area (67%) to build EBN swiftlet houses was the forested area. This was followed by, the coastral area (26.7%) and town area (6.7%). Based on fiield study results, forested areas were the best and most productive to build EBN swiftlet house. The mean EBN and individual swiftlet population from the different areas were as follows : 78 nests and 263 individuals in forested, 51 nests and 133 individuals in the coastal and 25 nests and 65 individuals in town area. From the environmental parameters collected it was shown that houses built in forested area hd the most suitable range for swiftlet adaptation. Air and surface temperatures were 31oC, relative humidity was 82%, light intensity 0.16LUX, sound level 50dB (internal) and 65dB (external). The result showed that EBN production was significantly higher in swiftlet houses with suitable haitat and environment factors.
