(Ecological Society of Australia, 2010)The history of conifers introduced earlier elsewhere in the southern hemisphere suggests that recent invasions in Argentina, Brazil, Chile and Uruguay are likely to increase in number and size. In South Africa, New Zealand ...

Fire management in Mediterranean-climate shrublands: a case study from the Cape fynbos, South Africa (British Ecological Society, 2010)1. Fire is an important process in Mediterranean-ecosystem shrublands, and prescribed burning is often used to manage these ecosystems. Analyses of past fire regimes are required to interpret biotic responses to fire, as ...
-
(Springer Science+Business Media B.V., 2010)This study is a first attempt at a holistic economic evaluation of South African endeavours to manage invasive alien plants using biological control. Our focus was on the delivery of ecosystem services from habitats that ...
-
(Blackwell Publishing Ltd., 2009)The factors controlling the extent of fire in Africa south of the equator were investigated using moderate resolution (500 m) satellite-derived burned area maps and spatial data on the environmental factors thought to ...
-
(Elsevier Ltd., 2008)This paper reports an assessment of the current and potential impacts of invasive alien plants on selected ecosystem services in South Africa. We used data on the current and potential future distribution of 56 invasive ...
-
(Open Journals Publishing, 2008)This paper provides an assessment of fire regimes in the Table Mountain National Park over the past four decades. We compiled a GIS database of all fires between 1970 and 2007 and analysed the fire regime in terms of the ...
-
(Open Journals Publishing, 2008)This paper reviews recent changes in fire management in the Kruger National Park, and assesses the resulting fire patterns against thresholds of potential concern. In 2002, a lightning-driven approach was replaced by an ...
-
(Springer Science+Business Media B.V., 2008)Alien conifers have been widely planted in the Southern Hemisphere. Australia, New Zealand and South Africa, all with long histories of alien conifer planting, have major problems with invasive conifers (‘‘wildings’’). ...
-
(Ecological Society of Australia, 2008-04)Research in Mediterranean-climate shrublands in both South Africa and Australia shows that recruitment of proteoid shrubs (non-sprouting, serotinous Proteaceae) is best after warm-season (summer and autumn) fires and worst ...
-
(2007)Establishment of catchment management agencies (CMAs) is central to South Africa’s new policy vision for achieving decentralised, participatory integrated water resource management. However, CMAs cannot directly engage ...
-
(CSIRO Publishing, 2007)The present paper reviews a long-term fire experiment in the Kruger National Park, South Africa, established in 1954 to support fire management. The paper’s goals are: (1) to assess learning, with a focus on relevance for ...
-
(2009)The history and development of ecologically-based fire management policies in savanna protected areas during the 20th century are reviewed. Research on fire in savannas began in the 1950s, and from the 1980s onwards, ...
-
(2009)The history and development of fire and invasive alien plant management policies in fynbos during the 20th century are reviewed. Fire was initially condemned outright as a destructive force, but as its vital role became ...

(Ecological Society of Australia, 2009)The history of conifers introduced earlier elsewhere in the southern hemisphere suggests that recent invasions in Argentina, Brazil, Chile and Uruguay are likely to increase in number and size. In South Africa, New Zealand ...
-
(Elsevier, 2009)Invasive alien trees and shrubs pose significant threats to biodiversity and ecosystem services in South African fynbos ecosystems. An ambitious initiative, the Working for Water program, commenced in 1995 to reduce the ...
