The plants listed below have been identified by the Panel as being absent or present in the EPPO region; as having a high potential for spread; as posing an important threat to plant health and/or the environment and biodiversity; and eventually as having other detrimental social impacts in the EPPO region. Xhosa names for invasive plants. Only with their participation and in cooperation with the local communities can the project’s goals be achieved. Invasive plant fuel loads increase fire intensity and severely compromise the recovery of natural vegetation. For example, the invasive alien plants Lantana camara and Urena lobata are reported both from forest, and waste and fallow lands, whereas species like Acanthospermum hispidum, Cestrum diurnum, and Evolvulus nummularius can be found both in agricultural land and waste and fallow lands mainly as noxious weeds (Hossain and Pasha 200). Alien plants have several negative impacts on landscapes. PRAs) and follows a meticulous approval procedure. Strip bark: Using a bush knife, strip bark away from tree from waist height down to soil. All Rights Reserved | EPPO Cloud [wwwzend912test]. Alien invasive plants are a problem because they: can waste a large proportion of national water resources (7% estimated in South Africa); lead to the loss of potentially productive land, and the loss of grazing potential and livestock production; reduce the ability to harvest indigenous natural resources; increase the problems associated with flooding and fires; cause erosion, destruction of rivers, siltation of dams and estuaries, and poor water quality; can cause a mass extinction of indigenous plants and animals. EPPO, in the framework of the International Plant Protection Convention (IPPC) and the Convention on Biological Diversity (CBD), is developing a cooperative Europe-wide strategy to protect the EPPO region against invasive alien plants. The impact of invasive plants. In this feature, The Water Page highlights a problem which faces many countries - that of invasive alien plant species. The label \"invasive\" is generally reserved for plants that have been introduced from other regions and spread like wildfire in their new habitats. Species recorded in the Alert List are assessed through the EPPO Prioritization process to determine whether they should fall into the List of Invasive Alien Plants, the Observation List, or a PRA should be conducted. What confers invasive alien plants a competitive advantage over native plants remains open to debate. This should represent an improvement on the current state of affairs, and should allow for better decision-making. Biological control can provide effective control in the short and medium term in some cases, and it is often the only really sustainable solution in the longer term. As a result of these studies, the following lists of invasive alien plants have been established. Invaders and weed species are plants that invade natural or semi-natural habitats; especially areas disturbed by humans and are commonly known as environmental weeds. They are non-native to an ecosystem, and may cause economic or environmental harm. This definition distinguishes invasive plants from other plants that more accurately are called \"aggressive.\" Invasive Alien Plants are plants which are imported into an eco-system which is not their natural habitat. SANBI Biodiversity Series The South African National Biodiversity Institute (SANBI) was established on 1 September 2004 through the signing into force of the National Environmental Management: Biodiversity Act (NEMBA) No. Eradication programs cost money. INTRODUCTION. Invasive alien plant species (IAP) are species whose introduction and/or spread outside their natural distribution threaten biological diversity. Invasive alien flora and fauna in South Africa: expertise and bibliography by Charles F. Musil & Ian A.W. Scientists have previously estimated that all invasive species - including microbes, animals and plants - cause damage of more than $1.4 trillion a year to the world economy. An invasive alien plant is a plant that is not indigenous to South Africa or the ecosystem in which it is found growing within the country. They are the single biggest threat to plant and animal biodiversity. No indigenous Vachellia / Senegalia tree (prev. This has particularly devastating impacts in developing countries which lack the resources to tackle the problem. When an invasive alien plant species takes hold within the ecosystem and starts to spread, they can displace indigenous plant species through competition, as well as bringing about changes in ecosystem structure and function. Considering the water prospects we are faced with, it is not a situation that we can afford. Macdonald Pretoria 2007. A list of invasive species has been published under the National Environmental Management: Biodiversity Act of 2004. They impact negatively on biodiversity, including decline or elimination of indigenous species – through competition for water and the disruption of local ecosystems and … EPPO, in the framework of the International Plant Protection Convention (IPPC) and the Convention on Biological Diversity (CBD), is developing a cooperative Europe-wide strategy to protect the EPPO region against invasive alien plants. Invasive alien plants are invading approximately 700,000 ha year −1 of natural communities in the United States (Pimentel et al., 2002).Invasive alien plants are defined as alien plants that reproduce offspring in very large numbers and at large distances from parent plants and thus have the potential to spread over a considerable area (Richardson et al., 2000). Follow label recommendations. Invasive alien plants are intense bullies, rapidly establishing and outcompeting indigenous species. In catchment areas which are infested with such plants, the eradication of invasive alien plants can often lead to significant increases in water available for other uses and may offer an alternative to traditional engineering solutions such as the construction of reservoirs and dams. Pests recently added to the EPPO A1/A2 Lists, EPPO A1/A2 Lists of pests recommended for regulation as quarantine pests, EPPO Observation List of invasive alien plants.
