Flowerheads cylindrical, galls on stems: Acacia stricta leaves: Acacia stricta flowers: Distribution. Observation - Acacia cyclops - Southern Africa. This study examines the fuel properties of two invasive woody alien plants in South Africa to determine how they affect fire behaviour. Two of the most successful invasive plant species in the fynbos are Acacia cyclops (rooikrans) and Acacia saligna (Port Jackson willow). Native distribution area. The seeds remain viable in the soil for many years. The two species are Acacia cyclops (Rooikrans), Pinus pinaster (Pines). Abstract Acacia saligna and Acacia cyclops are the dominant invasive alien plants of phosphorus‐poor, sand‐plain, lowland fynbos and the relatively phosphorus‐rich strandveld vegetation of the southwestern Cape of South Africa, respectively, but their ranges overlap. Once established, it is difficult to remove or replace. Acacia cyclops A. Cunn. Rooikrans (Acacia cyclops): ... (Melanterius servulus) was first released in South Africa in 1994. It is often claimed that invasions increase fire hazard through changing vegetation structure and increasing fuel loads. Keywords: Biological control, acacia, seed, New Zealand, South Africa Introduction A number of Australian Acacia species were introduced into South Africa in the early nineteenth century as ornamentals, for timber, and to stabilize drifting sand. Description: Photo 1: A. cyclops has a long flowering period. The spread of A. cyclops is a major threat to the fragile biodiversity of the strandveld and limestone fynbos vegetation. Binggeli (1999) classed A. cyclops as a highly invasive species. Provided by: .e-Flora of South Africa; Source: [. Henderson (2001) reports that it is invasive in South African forest gaps, dunes and along roadsides and watercourses. It was first introduced into South Africa around 1835 (Roux 1961, Stirton 1978) to stabilize dunes in the south-western part of the Western Cape Province. Acacia cyclops A. Cunn. ex G.

However, many signs (e.g. Leaves erect, rounded, prominent midvein and net venation: Leaves with 305 prominent longitudinal veins: Shrub or tree, Leaves erect, spreading. Acacia cyclops A. Cunn. ex G. Don (Fabaceae, Mimosoideae), originating from Western Australia, is a serious environmental weed in South Africa. It feeds on Rooikrans flowers and the developing seeds. Description: The trees had bio control galls on them in this area. There is little vegetation cover beneath an Acacia cyclops thicket. It is a category 2 declared invader in South Africa according to the Department of Agriculture, Conservation of Agricultural Resources Act, 1983 (Government of South Africa, 1983; Henderson, 2001). ex G.

Abstract Acacia cyclops is an invasive Australian tree in South Africa and a target for biological control using seed‐reducing agents. Southeast Australia. Photo 2: … Alien Invasive Plants List For South Africa. The only currently active legislation on weeds and invasive plants in South Africa forms part of the Conservation of Agricultural Resources Act, 1983 (Act No 43 of 1983) (CARA). Abstract Acacia cyclops is an invasive Australian tree in South Africa and a target for biological control using seed-reducing agents. Several acacia species are grown commercially in South Africa and this has limited biocontrol agents to those that reduceL:,~~oductive capacity. A midge (Dasineura dielsi) forms galls or swellings on the plant. ex Don Common Names Western Coastal Wattle, Rooikrans (South Africa). This reduces the number of seeds that are produced. The cause of the deaths has been attributed to a root and butt rot disease caused by the basidiomycete fungus Pseudolagarobasidium acaciicola. Observation - Acacia cyclops (Rooikrans) - Southern Africa. Source: South African journal of botany 2013 v.88 pp. Europe (Spain), South Africa, western USA (California). This is an extremely weedy species spread by birds into indigenous vegetation. Acacia cyclops, an invasive weed in South Africa, was initially imported to stabilize the sand dunes in the southern Cape.

Regulations 15 and 16 under this Act, which concern problem plants, were amended during March 2001. Flowering stage green buds, yellow bus, open flowers, senescing flowers often present at the same time, and not easily seen from a distance. It is a shrubby evergreen tree which grows to 6 m and has formed dense thickets, supplanting indigenous vegetation in many coastal areas ( Henderson 2001 ). Unarmed shrub or tree, up to 6 m high. Cunn ex G. Don is a shrubby leguminous tree originating from south-western Australia. Acacia cyclops G.Don. CARA is currently (2011) in the process of being revised. ex G. Don (Fabaceae) is a woody shrub that occurs mainly in arid and coastal areas due to its ability to withstand severe environmental pressures such as drought, soil salinity and sand blasts (Gill 1985). A. cyclops is also reported to use high volumes of water, ranking highest in its water consumption among the top twenty-five invader plant species in South Africa (Anon., 2003), and Working for Water (2003) suggest that the loss of native plants to A. cyclops thickets leaves the soil bare and vulnerable to wind and water erosion.
