(Fig. 1）被认为是世界上研究最少和最严重濒危的鳄鱼之一（IUCN 2002; Ross 1998; Thorbjarnarson 1992）。事实上，对C的生态学一无所知。由于栖息地的破坏、为鳄鱼养殖场收集鳄鱼和非法狩猎，东南亚的种群数量急剧下降（Ross 1998; Thorbjarnarson 1992）。现存的野生种群不再出现在越南（Platt and Tri 2000），印度尼西亚或马来西亚的最新信息很少（考克斯等人，1993; Ross 1998）。在泰国（Kreetiyutanont，1993年; Platt等人，2002年; Ratanakorn等人，1994年）和老挝（Mateus，2001年; Sawathvong，1994年; Stuart和Platt，2000年）的几个地方，仍然存在生存能力可疑的残留种群。虽然历史上广泛和丰富的柬埔寨（木村1969年; Thuok 1998年; Thuok和塔纳1994年），目前的分布和地位的C。暹罗在该国知之甚少。自然保护联盟鳄鱼专家组高度重视柬埔寨的调查（Ross 1998年; Thorbjarnarson 1992年），但直到最近，安全问题严重限制了实地调查（Thuok 1998年）。政治局势的改善使实地调查成为可能，大量的C。最近在豆蔻山的几个排水沟中发现了暹罗人（Daltry和Chheang 2000）。我们在此提出的数据发生和自然历史的一个迄今未报道的人口C。柬埔寨西南部Sre Ambel河沿岸沿着的暹罗。
(Fig. 1) is considered one of the least studied and most critically endangered crocodilians in the world (IUCN 2002; Ross 1998; Thorbjarnarson 1992). Virtually nothing is known concerning the ecology of C. siamensis in the wild, and populations throughout Southeast Asia have declined precipitously as a result of habitat destruction, collecting to stock crocodile farms, and illegal hunting (Ross 1998; Thorbjarnarson 1992). Extant wild populations no longer occur in Vietnam (Platt and Tri 2000), and there is little recent information from either Indonesia or Malaysia (Cox et al. 1993; Ross 1998). Remnant populations of questionable viability persist at several localities in Thailand (Kreetiyutanont 1993; Platt et al. 2002; Ratanakorn et al. 1994) and Laos (Mateus 2001; Sawathvong 1994; Stuart and Platt 2000). Although historically widespread and abundant in Cambodia (Kimura 1969; Thuok 1998; Thuok and Tana 1994), the current distribution and status of C. siamensis in the country are poorly known. Surveys in Cambodia were accorded high priority by the IUCN Crocodile Specialist Group (Ross 1998; Thorbjarnarson 1992), but security concerns seriously limited field investigations until recently (Thuok 1998). An improved political situation now makes fieldwork possible and significant numbers of C. siamensis were recently found in several drainages of the Cardamom Mountains (Daltry and Chheang 2000). We herein present data on the occurrence and natural history of a hitherto unreported population of C. siamensis along the Sre Ambel River in southwestern Cambodia.
