ABSTRACT Air temperatures have increased globally over the past decades, while rainfall changes been more variable, but are taking place. In South Africa, substantial climate‐related impacts predicted, and protected area management agencies will need to respond actively impacts. It is critical for understand way in which climate changing locally predict appropriately. Here, first time, we quantify observable temperature African national parks five ten decades. Our results show significant...
Abstract: We developed a method to predict the potential of non‐native reptiles and amphibians (herpetofauna) establish populations. This may inform efforts prevent introduction invasive species. used boosted regression trees determine whether nine variables influence establishment success introduced herpetofauna in California Florida. an independent data set assess model performance. Propagule pressure was variable most strongly associated with success. Species short juvenile periods...
In 1945, the Royal Society of South Africa published a wide-ranging report, prepared by committee led Dr C.L. Wicht, dealing with preservation globally unique and highly diverse vegetation south-western Cape. The publication Wicht Committee's report signalled initiation research programme aimed at understanding, ultimately protecting, ecosystems Cape Floristic Region. This has continued for over 70 years, it constitutes longest history concerted scientific endeavour conservation an entire...
Protected areas face mounting pressures, including invasion by alien plant species. Scientifically sound information is required to advise invasive species management strategies, where early detection and rapid response particularly important. One approach this determine: (i) the relative importance of pathways which a introduced, (ii) range likely impacts associated with each species, (iii) relationship between impacts, assess threats posed different introductions. This assessment was...
Abstract Estimating and planning for the impacts of climate change on biodiversity protected areas is a major challenge conservation managers. When these are topographically heterogenous contain species' entire ranges, this exacerbated because coarse spatial scales Global Circulation Model projections provide limited information within‐park management. South Africa's Table Mountain National Park, home to three endemic amphibian species in just ~24,500 hectares, provides case study...
Abstract The global trade in reptiles for pets has grown rapidly recent decades. Some species introduced by the pet have established and become invasive, example Burmese python Florida. Although there are currently no invasive alien South Africa, last 30 years seen an exponential increase number of introductions increasing from countries. We determine analyse presence abundance African reptile trade. This serves as a background to efforts overhaul management regulation this trade,...
Abstract This paper assesses progress towards the control of biological invasions in 18 protected areas (PAs) covering 677 584 ha Cape Floristic Region (CFR), and whether has been sufficient to achieve Target 6 Kunming-Montreal Global Biodiversity Framework. We used eight indicators for assessing inputs (quality regulatory framework, money spent planning coverage species areas), outputs (species treated), outcomes (effectiveness area treatments) management. The estimated over 13 years...
Aim Charles Darwin posited that introduced species with close relatives were less likely to succeed because of fiercer competition resulting from their similarity residents. There is much debate about the generality this rule, and recent studies on plant fish introductions have been inconclusive. Information phylogenetic relatedness potentially valuable for explaining invasion outcomes could form part screening protocols minimizing future invasions. We provide first test hypothesis...
Objectives: A core objective in South African National Parks (SANParks) is biodiversity conservation and the maintenance of functional ecosystems, which compromised by alien species invasions. The 2016 Alien Invasive Species Regulations Environmental Management: Biodiversity Act (NEM:BA) requires landowners to develop management plans for invasive species, as well report on status efficacy control. Method: To compile list, we started with 2011 SANParks list. Name changes were updated...
SUMMARY Despite significant expansion of the global protected area (PA) network, this investment has not commonly been matched by in their management. This includes managing trade-offs between social and biodiversity goals, including resource use PAs. While some resource-use activities receive attention, full suite resources extracted from PA systems is rarely documented. paper illustrates potential risk to ecological performance through a survey harvested South Africa's national parks. Even...
Resource harvesting is permissible within South African protected areas under certain conditions as part of benefit sharing that seeks to strengthen relationships with communities living adjacent parks. However, not all resource use authorised and little currently known about what harvested, or the extent impacts in This limits capacity monitor set boundaries for such use. paper provides a checklist resources harvested each 19 national parks managed by National Parks. Data were gathered...
Background: The effectiveness of invasive alien species management in South Africa, and elsewhere, can be mproved by ensuring there are strong links feedbacks between science management. CAPE Invasive Alien Animals Working Group (CAPE IAAWG) was established 2008 to enhance cooperation among stakeholders such as implementing agencies researchers, thereby improve the animals Greater Cape Floristic Region.Objectives: In this article we highlight where how working group has advanced our...
Plant and animal checklists, with conservation status information, are fundamental for management. Historical field data, more recent data of digital origin data-sharing platforms provide useful sources collating species locality data. However, different biodiversity datasets have formats inconsistent naming systems. Additionally, most do not an easy option download by protected area. Further, data-entry-ready software is readily available organization staff limited technical skills to...
Abstract Invasive alien species (IAS) pose a key threat to biodiversity, the economy and human well-being, continue increase in abundance impact worldwide. Legislation policy currently dominate global agenda for IAS, although translation localised success may be limited. This calls wider range of responses transform IAS management. An under-appreciated strategy achieve come from bottom-up, experimental innovations (so-called “seeds”), which offer alternative visions what possible management...
