No Thumbnail AvailableDocumentBiosecurity in forestry: A case study on the status of invasive forest tree species in Southern Africa 2003
Also available in:
No results found.Invasive tree species are now considered to be a threat to the biological diversity of Southern Africa. Most of the invasive tree species in Southern Africa were either deliberate or accidental introductions. Most of the invasive tree species are exotic, with only one or two being indigenous. These invasive exotic tree species are causing significant environmental and economic damage to the ecosystems of the region. The documented environmental damage includes: (i) reduction of species richness; (ii) reduction of stream flow; (iii) alteration of the nutrient status of soil, (iv) alteration of the biomass of ecosystems, and (v) changes in fire intensity due to altered fuel load. In South Africa, an estimated 100 739 km2 (8.07 percent of national area) have been affected by invasive alien tree species. -
Book (stand-alone)Common plants of Maldives 2016
Also available in:
No results found.The book includes information on 270 species of vascular plants observed during our surveys conducted in more than 50 islands in Maldives. It deals with the common native as well as all alien plants which are currently occuring in the Islands. Information provided includes the current valid name of the plant, most popular synonyms, names in Dhivehi and a few common English names. Plant descriptions given include data on vegetative characters avoiding confusing scientific terms, as far as possibl e. Data collected from the fi eld are the source of information on the occurrence and pattern of distribution in different islands. Threats and damages caused by invasive alien species are also included. Ethnobotanical information collected during the study is given under uses. However, use of any plant/plant parts for medicinal purposes, based on the information provided in this book, cannot be recommended for want of evidence on the non-toxicity of the plant/ plant parts. So, the readers of th e book are advised to refrain from use of the plant/ plant parts for medicinal purposes. It is hoped that this book will be used as a field guide for identification of native, nonnative and invasive plants of Maldives by specialists and non-specialists alike.
