Species Rarity

Background: Picralima nitida (Apocynaceae) is an important African medicinal plant species. It is frequently used in traditional medicine and pharmaceutical industries for manufacture of drugs against infectious diseases, malaria, diabetes and cancer. Despite its important, the species can be rare, especially in the Dahomey Gap (in contrast to the Guineo-Congolese region). There is also a controversy on its distribution. Without knowing the drivers of plant species rarity it is impossible to address the issue of the controversy of its distribution and unsustainable use as well as safeguarding endogenous knowledge of its uses.  Methods: Ethnobotanical surveys were conducted in the Dahomey Gap with 120 informants randomly interviewed. A literature review of scientific papers and books was used to provide information on the uses, distribution and threats of the species in the Guineo-Congolese region. Results: The results revealed that P. nitida products were more expensive in the Dahomey Gap than the Guineo-Congolese region. All parts of the species were collected and used for 34 treatments. The species had low density and distribution in Dahomey Gap compared to the Guineo-Congolese region. Conclusions: P. nitida is used across its distribution areas with important economic values. Adapted management strategies are needed for the sustainable use and conservation of the species..

Rock Outcrop Ecosystems

Rare plants and their habitats are integral to the conservation of biodiversity in many areas. With increasing habitat destruction and fragmentation, there is an urgent need to identify elements of diversity that are at risk, to adequately address conservation priorities, and successfully implement management strategies. In this research project, plant species rarity in rock outcrop ecosystems occurring on the Gulf Islands in southwestern British Columbia was examined at 13 study sites (3000 m2 area examined per site). Bryophytes comprised the largest portion of rare taxa; 18 of the 20 provincially rare taxa were mosses, including two species new to Canada. Challenges facing rare plant species conservation were considered from a landscape management perspective. Rock outcrops represent non-equilibrial, primary successional systems; some form of perpetual large-scale disturbance (e.g., climate and (or) grazing) may be integral to maintaining these ecosystems, their constituent habitats, and the occurrence of many rare moss species. In contrast with vascular plants, which are of focal concern in relatively deeper-soiled Garry oak meadows (i.e., native herbs and grasses), bryophytes have limited competitive ability. As such, the rare bryophytes of rock outcrop ecosystems are likely to be highly sensitive to successional development within sites (i.e., factors reducing the availability of early successional habitats) that may arise through land use modifications and (or) changes in local climatic conditions related to global warming.
