Expanding protected areas beyond their terrestrial comfort zone: identifying spatial options for river conservation

Author: Nel, JL ; Reyers, B ; Roux, DJ ; Cowling, RM Date: Aug 2009 There has been very little consideration of freshwater ecosystems in identifying and designing protected areas. Recent studies suggest that protected areas hold enormous potential to conserve freshwater biodiversity if augmented with appropriate ... Read more
Geomorphic provinces of South Africa, Lesotho and Swaziland: A physiographic subdivision for earth and environmental scientists

Author: Partridge, TC ; Dollar, ESJ ; Moolman, J ; Dollar, LH Date: Feb 2010 This work has drawn upon previous attempts to define geomorphic provinces, but also on more recent work on the geological and geomorphological evolution of southern African fluvial systems. It has also used Digital Terrain Model (DTM)-derived ... Read more
Improving the key biodiversity areas approach for effective conservation planning

Author: Knight, AT ; Smith, RS ; Cowling, RM ; Desmet, PG ; Faith, DP ; Ferrier, S ; Gelderblom, CM ; Grantham, H ; Lombard, AT ; Maze, K ; Nel, JL ; Parrish, JD ; Pence, JQK ; Possingham, HP ; Reyers, B ; Rouget, M ; Roux, D ; Wilson, KA Date: Mar 2007 The key biodiversity areas (KBA) approach aims to identify globally important areas for species conservation. Although a similar methodology has been used successfully to identify important Bird Areas, the authors have identified five limitations ... Read more
Invasive alien plants and South African rivers: a proposed approach to the prioritisation of control operations

Author: Van Wilgen, BW ; Nel, JL ; Rouget, M Date: 2007 Parallel initiatives in South Africa have been addressing the prioritisation and management of invasive alien plant species, the prioritisation of rivers for the conservation of biodiversity, and broad-scale planning for water resource ...

Landsat-8 based coastal ecosystem mapping in South Africa using random forest classification in Google Earth Engine

Author: Bessinger, M ; Lück-Vogel, Melanie ; Skowno, A ; Conrad, F Date: Nov 2022 Coastlines worldwide are home to an increasing number of people and are subject to many pressures. This, combined with natural dynamics and hazards, often results in the degradation of coastal and marine ecosystems and infrastructure. Therefore, ... Read more
Landscape fragmentation in South Coast Renosterveld, South Africa, in relation to rainfall and topography

Author: Kemper, J ; Cowling, RM ; Richardson, DM ; Forsyth, GG ; McKelly, DH Date: Apr 2000 The South Coast Renosterveld has been fragmented extensively by agriculture. The extent of this fragmentation in terms of overall habitat loss, fragment sizes and fragment numbers has not been described previously, thereby limiting the ... Read more
Predicting freshwater habitat integrity using land-use surrogates

Author: Amis, MA ; Rouget, M ; Balmford, A ; Thuiller, W ; Kleynhans, CJ ; Day, DJC ; Nel, JL Date: Apr 2007 Freshwater biodiversity is globally threatened due to human disturbances, but freshwater ecosystems have been accorded less protection than their terrestrial and marine counterparts. Few criteria exist for assessing the habitat integrity of ... Read more
Remote sensing based ecosystem state assessment in the Sandveld region, South Africa

Author: Lück-Vogel, Melanie ; O'Farrell, Patrick J ; Roberts, W Date: Dec 2012 We present a remote sensing based approach for assessing ecosystem state or intactness to inform land use management and conservation planning. Using segmented multispectral medium resolution satellite imagery, parameters related to the image ... Read more
Safeguarding biodiversity and ecosystem services in the Little Karoo, South Africa

Author: Egoh, Benis N ; Reyers, B ; Carwardine, J ; Bode, M ; O'Farrell, Patrick J ; Wilson, KA ; Possingham, HP ; Rouget, M ; De Lange, Willem J ; Cowling, RM Date: Feb 2010 Global declines in biodiversity and the widespread degradation of ecosystem services have led to urgent calls to safeguard both. Responses to this urgency include calls to integrate the needs of ecosystem services and biodiversity into the ... Read more
Scale-based freshwater conservation planning: towards protecting freshwater biodiversity in KwaZulu-Natal, South Africa

Author: Rivers-Moore, NA ; Goodman, PS ; Nel, JL Date: Jan 2011 River systems have strong linear linkages and require innovative solutions to capture these linkages from aquatic conservation planners. The authors applied an approach to freshwater conservation planning to freshwater ecosystems of KwaZulu-Natal ... Read more
A spatial assessment of riverine ecosystems and water supply in a semi-arid environment

Author: Smith-Adao, Lindie B ; Nel, JL ; Le Maitre, David C ; Maherry, A ; Swartz, ER Date: Dec 2011 A spatial assessment was conducted in the semi-arid area of South Africa, to: (1) identify priority areas for the conservation of river and groundwater ecosystems; (2) examine surface and groundwater quality for human consumption and (3) ...

Use of landscape-level river signatures in conservation planning: a South African case study

Author: Roux, D ; De Moor, F ; Cambray, J ; Barber-James, H Date: Dec 2002 A strategy for assigning priorities in biodiversity conservation was developed for the rivers of the proposed Greater Addo Elephant National Park (GAENP) in South Africa. Due to the limited availability of biological information on the ... Read more
