1 Introduction Reptiles of Takamanda Forest Reserve, Cameroon Matthew LeBreton, Laurent Chirio, and Désiré Foguekem Cameroon has a rich reptile fauna of more than 265 species (Chirio and LeBreton in prep.), resulting from the country’s varied landscape and climate and its center of diversity in the western highlands. While this diversity is well known and although many unique and characteristic species have been recorded from Cameroon, there are few published local inventories. Most lists were compiled during general expeditions across Cameroon (Sternfeld 1908, 1909; Müller 1910; Neiden 1910a,b; Mertens 1938, 1940, 1968; Monard 1951; Perret and Mertens 1957; Böhme 1975b; Joger 1982; Böhme and Schneider 1987) or through studies of a taxonomic nature based on specimens in European or American museums (e.g., Loveridge 1947, Klaver and Böhme 1992). Notable exceptions include studies of snake fauna from Yaoundé (Gauduin 1970) and western Cameroon (Stucki-Stern 1979) and short-term research on fauna in Campo Fauna Reserve (Ota et al. 1987) and Korup National Park (Lawson 1993). The non-governmental organization (NGO) CAMHERP has been operating in Cameroon since 1998, compiling an atlas of reptiles and providing regional and local inventories for other NGOs, the government sector, and regional projects. This paper presents the first list of reptiles from Takamanda forest (Takamanda Forest Reserve and adjoining areas), based on four excursions to the area in 2001 and 2002, in cooperation with the Takamanda Forest Surveys Project (GTZ/MINEF PROFAMAMFE) and Wildlife Conservation Society. 2 Study area Chapter 6 The southern border of Takamanda Forest Reserve (TFR) is located approximately 15 km north of Mamfe in the Southwest Province of Cameroon (Figure 1 Chapter 1). The reserve, approximately 67,500 ha in size, follows the Cameroon/Nigeria border for about 30 km. In a simple breakdown of natural vegetation, four major types can be determined: lowland forest, medium altitude forest, montane forest, and elevated savanna (Sunderland et al. this volume). Derived vegetation types include cultivated areas, farm bush, and secondary forest around the reserve. Altitude varies from 100 m to about 1,600 m. Four field trips were conducted in and around TFR over the course of one year. The first, from 14 - 30 May 2001, focused the areas of Matene and Mende. At Matene, palm plantations, farm bush, dense lowland humid forest, and mid-elevation forest were examined, while at Mende, gallery forest, montane forest, elevated grassland, and farmland were surveyed. The second trip, from 2 - 17 August 2001, centered on the villages of Atolo—where sub-montane forest, ridge forest, farm bush and cocoa farms were the dominant vegetation types—and Tinta, where woodland savanna, moist evergreen forest, and the interface between these vegetation types were assessed. The third and fourth trips, from 6 - 19 December 2001 and 28 – 31 May 2002, examined lowland forest areas in the south of the reserve in the vicinity of the villages of Takamanda, Obonyi 1 and 2, and Kekpane (Figure 2 in Chapter 1).
