E-mail: marco.schmidt@senckenberg.de Abstract: The Arly National Park of southeastern Burkina Faso is in the center of the WAP complex, the largest continuous system of protected areas in West Africa. Although well known for its large mammal populations, its flora has largely been unexplored until recently. The plant species composition is typical for sudanian savanna areas with a high share of grasses and legumes and similar to other protected areas of the complex, the neighbouring Pama reserve and W National Park. It has more species in common with the classified forest of Kou in SW Burkina Faso than with the geographically closer Sahel reserve. The 490 species belong to 280 genera and 83 families. The most important life forms are phanerophytes and therophytes. Introduction For Burkina Faso, only very few comprehensive assessments of local floras have been published (e.g., Guinko and Thiombiano 2005; Ouoba et al. 2006; Gnoumou et al. 2008). There is virtually no information available about the flora of the country’s protected areas, although this knowledge is important for the conservation of endangered species and habitats and the management of these protected areas. Even on the larger scale of West Africa, local assessments of the flora are mainly restricted to the forest region (Jongkind et al. 1999; Jongkind 2007a, b; Aké Assi et al. 2005; Ekpe 2005; Holié and Delamou 2004; 2006; Couch and Williams 2006; Luke 2007; Siaw and Dabo 2007). Following a recent publication on the partial faunal reserve of Pama (Mbayngone et al. 2008) this paper continues to close gaps in knowledge on the plant diversity of West African protected areas by providing a comprehensive checklist of Arly National Park. Materials and Methods Study Area The Arly National Park (Figure 1) resulted from the merging of the total reserve of Madjoari and the total reserve of Arly in 1978 (Ouattara 1994) and is presently a protected area of IUCN category II. The forestry authorities have further increased the area to include a part of the Gobnangou mountain chain. The park covers now an area of 120.000 ha and is part of the so-called WAP complex (W-Arly-Pendjari), a large transfrontier complex of nature reserves consisting of Arly National Park, the neighbouring Pendjari National Park south of the Pendjari river in Benin, the W National Park shared by Benin, Burkina Faso and Niger, several partial faunal reserves and hunting zones. Hunting is forbidden in Arly National Park and by lack of infrastructure there is only limited ecotourism possible at present. The whole complex is well-known for its wildlife including large populations of elephants and lions (Lamarque 2004; Balança et al. 2007). It has a much denser Check List | Volume 7 | Issue 1 | 2011 vegetation than the surrounding areas, where agriculture has encroached on savannas and forests and tall perennial grasses almost disappeared, so that its borders are even visible from space (e.g. in the map in UNEP 2008). Among the reserves of the WAP complex, Arly has a high habitat diversity, including extensive gallery forests of the Arly and Pendjari rivers (Figure 2), sandstone hills of the Gobnangou chain (Figure 3), sudanian savannas dominated by tall perennial grasses and closed woodlands. The park has been inventoried for birds (Green and Sayer 1979) and large mammals (Green 1979) but detailed plant information is up to now restricted on studies on woody plant structure (Ouédraogo et al. 2008) and regeneration (Ouédraogo et al. 2009). Data collection The species listed here were compiled mainly from the surveys by O. Ouédraogo in the years 2004 to 2007 covering all habitat types of the park, complemented by several herb layer relevés conducted by M. Schmidt in Figure 1. Map of Arly National Park with boundary and watercourses. Altitudinal information is taken from SRTM 90 data. 085 Ouédraogo et al. | Magnoliophyta, Arly National Park, Burkina Faso 2002 (Schmidt 2006), rapid assessments of an expedition in late 2008 and specimen data from the herbarium of the University of Ouagadougou (OUA) and the Herbarium Senckenbergianum (FR). The species names and synonymy follow the African Flowering Plants Database (Gautier et al. 2006), families are assigned according to Brummit (1992), but family names like Compositae or Gramineae are replaced by the standard names referring to the type genus. Species have been determined using Hutchinson and Dalziel (1954-1972), Berhaut (1971-1988), Arbonnier (2002), Akoègninou et al. (2006) and the West African Plants Database (http://westafricanplants.senckenberg. de, Brunken et al. 2008). Life form information has been assembled from Guinko (1984), Aké Assi (2001; 2002) and supplemented by own observations. The more detailed information in the mentioned literature has been reduced to the main types, as defined by Raunkiaer (1905), in order to have a comparable definition of life forms. The chorological types refer to the phytochoria of White (1983), also used in other studies of the region (Sinsin 2001; Mbayngone et al. 2008). Data analysis The comparisons with other reserves in Burkina Faso are based on the publications of Guinko and Thiombiano (2005) for the Forêt Classée de la Kou, Mbayngone et al. (2008) for the Reserve partielle de la faune de Pama, Schmidt et al. (2008) for the Reserve sylvo-pastorale et partielle de faune du Sahel and Arbonnier et al. (2002) for the Niger part of the Parc National de la W du Niger. The nomenclature has been harmonized using the synonymy of the African Flowering Plants Database (Gautier et al. 2006), therefore slight differences from the original publications are possible. Calculation of species in common and exclusive to certain reserves has been done in Microsoft Excel, calculation of Sørensen indices and clustering has been done in Community Analysis Package (v.4, Pisces Conservation Ltd.). Results and Discussion The Arly National Park contributes highly to the conservation of the country’s flora. We found 490 species (Table 1) which represent about 30% of all vascular plants inventoried in Burkina Faso (Schmidt et al. 2010). The Park’s flora consists of 280 genera belonging to 83 families. The ten most species rich families are Fabaceae (95 species), followed by Poaceae (88), Cyperaceae (27), Rubiaceae (22), Combretaceae (19), Euphorbiaceae (14), Acanthaceae (13), Convolvulaceae (13), Malvaceae (12) and Asteraceae (11) (Figure 4). The family composition (Figure 4) is very similar to the family composition of the nearby Pama reserve (Mbayngone et al. 2008). The most striking difference is the higher family richness in Arly (83 as compared to 73) and the higher species richness in some families, especially the Combretaceae. Similar to the family composition of the Pama reserve and W National Park, the dominance of grasses and legumes in Arly National Park is very typical of savannas (Bourlière and Hadley 1970) and is found throughout Burkina Faso (Schmidt et al. 2005; Schmidt et al. 2010), up Check List | Volume 7 | Issue 1 | 2011 to the very North (Schmidt et al. 2008) and in the nearby Atakora mountains of Benin (Wala unpublished data). The ten most species rich genera are Indigofera (18 species), Combretum (11), Cyperus (11), Ipomoea (9), Acacia (8), Crotalaria (8), Andropogon (7), Eragrostis (7), Hyparrhenia (7) and Tephrosia (7). Altogether they constitute 19% of the National Park’s flora. The life form composition (Figure 5) is dominated by phanerophytes (40%) and therophytes (33%), followed by chamaephytes (10%), hemicryptophytes (9%), geophytes (5%), hydrophytes (2%) and helophytes (1%). This is a typical pattern for the North Sudanian Zone (Hahn-Hadjali et al. 2006). Towards the Sahel the portion of therophytes increases at the expense of the phanerophytes (Schmidt et al. 2005). In the South Sudanian Zone phanerophytes are even more important (Koulibaly et al. 2006). The chorological spectrum of the flora (Figure 6) is characterized by a high proportion of species specific to savanna regions (sudanian, sudano-zambesian) and a high proportion of wide-spread species (pantropical, paleotropical, pluriregional african, afrotropical). Sudanoguinean and guineo-congolian elements are mainly confined to the gallery forests. The comparison of published inventories of protected areas of the region (Figure 7, Table 1) includes two Figure 2. Gallery forest along the Arly river with Ziziphus spina-christi at the edge of the water. Figure 3. Sandstone hills of the Gobnangou mountains near the eastern entrance to the Arly NP. 086 Ouédraogo et al. | Magnoliophyta, Arly National Park, Burkina Faso neighbouring areas of the so-called WAP complex - the Pama reserve (Mbayngone et al. 2008) and the Niger part of the W transboundary park (Arbonnier et al. 2002), another sudanian site in the SW of Burkina Faso - the classified forest of Kou (Guinko and Thiombiano 2005) and the country’s largest protected area - the Sahel reserve (Schmidt et al. 2008). Most similar are Pama and Arly, grouping together with the W Park. As the geographic position in the center might suggest, Arly is more similar to either Pama or W Park, than these are to each other and has the fewest species exclusively found within its area. The mentioned three areas of the WAP complex are most similar to the Kou forest, the closer they are geographically. The environmental differences and larger distance to the other reserves makes the Sahel reserve the most distinctive in species composition. Although it has the lowest total species richness of the larger reserves (Kou forest is very small), it has the highest number of “exclusive” species. Figure 4.
