Northern Edge

Biological studies in Guinea have been very patchy, leaving much of the country almost unsurveyed. In 1992 the Fauna and Flora Preservation Society funded a 10-day field visit to Kounounkan, a relict forest at the northern edge of the Upper Guinea Forest Block. The survey found a variety of habitats and high biodiversity, including two vulnerable and one endangered species. Hunting pressure appears to be low and the site is very well suited for the development of further conservation initiatives.

Conservation of Australian plants depends on a spectrum of activities from descriptive and experimental biological studies to active management and restoration of wild ecosystems by local communities who value their native biota. On the basis of the premise that available resources for conservation will not allow for all threatened biodiversity to be saved, some systematists and conservation geneticists argue that phylogenetic relationships should be used to set conservation priorities. The principle advocated is that characters, not species number, should become the currency of conservation, that cladistic analysis of phylogenetic pattern provides a predictive means of modelling the underlying distribution of characters among taxa, and that priority should be given to that subset of taxa with the greatest number of character states. This approach has been applied for some time in the conservation of genetic resources within species (e.g. Eucalyptus caesia), and has been an extra impetus for action with taxonomically isolated endangered species such as the recently discovered araucarian Wollemi pine (Wollemia nobilis). However, most plant conservation activity in Australia has paid little heed to phylogenetic relationships. Degree of threat has been a driving motivation, with endangered species receiving legislative and management attention irrespective of their systematic relationships. Moreover, the current revolution in understanding plant phylogeny associated with DNA sequence studies highlights the need for caution in accepting results of morphologically based analyses. A series of studies on the kangaroo paw and bloodroot family Haemodoraceae highlights this cautionary tale. The derivation of phylogenetic principles relevant to ecosystem and landscape processes is a new field of some promise to conservation managers. An understanding of the Gondwanan origins and landscape evolution of the south-west Australian flora provides a useful case study. Scaling up phylogenetic knowledge of genetic resources within species, and of the evolutionary relationships of taxa to an integrated overview of best management practices for all taxa at the local landscape level, is perhaps the most effective contribution phylogeneticists might make to help conserve Australian plants.

Physical Type

Opening ParagraphThe Kru, a West African Negro group, inhabit the central and southern part of Liberia. They are surrounded by the Basa peoples to the north-west, by the Grebo to the south-east and by the Putu to the north-east. The informant, Thomas Tarbour (Sieh Tagbweh), from whom the following material was derived, was a native of Grand Cess (Siglipo), a large coast town near the border of the Grebo country. The Kru, along with other related groups in that part of West Africa, have a tradition of having migrated from far to the north-east. The physical type is that of the short, stocky Bush negro. No archaeological work has been done in the region, and such ethnological material as has been collected is a mere beginning.

Abstract Choeropsis liberiensis (Morton, 1849), commonly called the pygmy hippopotamus or pygmy hippo, is the only extant species in the genus Choeropsis. A solitary, forest-dwelling ungulate endemic to the Upper Guinean forest ecosystem in West Africa, it is classified as “Endangered” by the International Union for Conservation of Nature and Natural Resources and is a Convention on International Trade in Endangered Species of Wild Flora and Fauna (CITES) Appendix II species. The smaller of the two extant hippopotamids, it is relatively uncommon in zoological facilities and private collections worldwide.

Conservation Assessments

West Africa is a floristically understudied region that is facing severe environmental changes in the 21st century. Basic distribution data and information on the conservation status for most plant species of the region are scarce, and good information only exists for small areas of interest or for key species. This lack of knowledge seriously hampers urgently needed regional conservation efforts. Here we present comprehensive distribution information and preliminary, automated species conservation assessments for the flora of Burkina Faso, a country in tropical West Africa with a flora and vegetation typical for the savanna belt of the region. We documented and analysed the distribution of 1,568 species or 80% of the flora of Burkina Faso based on an expert curated dataset comprising ca. 150,000 occurrence records from herbarium specimens and vegetation surveys. We used this dataset and environmental niche models to calculate three indicator variables for a preliminary, automated conservation assessment. We classified 350 species (18% of the flora, excluding introduced species) as potentially "Critically Endangered", "Endangered", "Vulnerable" or "Near-Threatened" on the national level. The analyses confirmed species-rich areas in the south-west and south-east of the country, and showed a particular concentration of potentially Endangered species in the south. Furthermore, the proportion of potentially Endangered species differed between plant families, growth forms and habitats. Our results set the base for further plant geographical and ecological studies and are a data-driven baseline for further conservation assessments and large scale conservation strategies of the West African flora.

The plant Ashoka (Saracaasoca Roxb.) is an endangered species in the flora which is very useful in different condition of the health of a mankind. But different source plants are used in the name of Ashoka in the rural area of Moodubidire. Different parts of Ashoka are also useful as medicine in various disorders. Hence a preliminary survey work on ethno-medical uses of Ashoka were conducted at Moodubidire Talluk in Karnataka State. It was found that the various source plants such as Saracaasoca Roxb., Humboldtia brunois Wall., Xylia xylocarpa Roxb., Polyalthia longifolia Sonn. etc. were used in the name of Ashoka. But Saracaasoca (Roxb). is being popu- lar and authentic source of Ashoka, different parts of parts of Ashoka are beneficial in the management of differ- ent diseases in different forms. The bark of Ashoka is said to be useful in the management of menorrhagia, the flowers in gastritis & piles, leaves in acne vulgaris, intestinal worms and stem in the management of Skin diseas- es. The complete documentation on the ethno-medico-botanical utility of different parts of Ashoka in the Moodu- bidire Range were done in the present study.

Tourism Revenue

ABSTRACTCash-constrained wildlife departments must increasingly look towards revenue-generating activities such as sales of permits for hunting common species combined with fines for those caught with rare species. Pertinent to west Africa, an optimal enforcement model demonstrates the conditions under which a department with neither external budget nor tourism revenue can fully protect a rare species, and the impact on other species and local hunters' livelihoods. The department's effectiveness is shown to depend critically on the extent to which hunters can discriminate among different species. Improvements in hunting technology selectivity are therefore a substitute for increased enforcement spending.
