Host specificity in the Rhizobium symbioses of two Aspalathus species and an invasive alien legume, Acacia saligna
… discussed. A widespread invasive alien legume, Acacia saligna . was grown in the same soils and soil solutions. It formed nodules only in the three soils from within the distribution of Aspalathus capensis. The degree of nodulation varied between these soils. The possible importance of …

Ecosystem level impacts of annual and perennial N2-fixing invasive alien plants in the fynbos vegetation of South Africa
… two different N2-fixing invasive alien plants, Acacia saligna and Lupinus luteus.

Low cost, small-scale charcoal production in the Western Cape
… was successfully produced from the alien species Acacia Saligna. Carbonisation was effected using a Tongan drum kiln and average yields on a dry basis of 19.1 (excluding fines production) were attained. With fines included, the yield increased to 31.4 . It was shown that the earnings of …

Alien plant invasion on the Agulhas Plain : a detailed description of invasion patterns
… at high densities, >130% canopy cover. Acacia saligna and Acacia cyclops are the most widely distributed species, covering 41 % and 53% of the total area. Effectively determining invasive alien species richness required the use different variables to those used in this study. Invasive …

Irrigation of acacia and eucalyptus species with waters of different salinities in a semi-arid environment in Formentera, Balearic Islands
… Two species, Eucalyptus gomphocephala D.C. and Acacia saligna (Labill.)H.Wendl. were tested with four irrigation treatments. Irrigation volume and frequency were calculated by evaporation pan and tensiometer balance. No allowance other than winter rainfall (approximately 300mm) was made for …

The effects of recent landuse on a fynbos site
… soils prone to colonisation by invasive acacias. The increase in cultivated land surrounding the site after 1962 served to isolate the fynbos stand from nearby fynbos communities and exacerbate erosion of soils and their subsequent deposition on the Fynbos Site. Extraneous transformation …

A preliminary study of the impacts of alien Acacia infestation (A saligna) on the relative rates of nitrogen and phosphorus cycling in Lowland Fynbos, southwestern Cape, South Africa
… 7-8 year old fynbos vegetation and an adjacent Acacia saligna (Labill.) Wendl. infestation. While there was no significant difference in soil temperature between fynbos and acacia sites, soil moisture and organic matter content was significantly higher in the acacia soils. This favoured …

Conservation implications of the invasion of southern Africa by alien organisms
… the most intractable shrub invader of fynbos, Acacia saligna, was developed from the results of a field experiment at the Pella site. Practical field- scale control of these invasions was assessed to be feasible, using the results of repeated monitoring of permanent plots in the Cape of Good …
