Indicators are effective tools for summarising and communicating key aspects of ecosystem state have a long record use in marine pollution fisheries management. The application biodiversity indicators to assess the status species, habitats, functional diversity conservation policy, however, is still developing multiple indicator roles features emerging. For example, some operational trigger management action when threshold reached, while others play an interpretive, or surveillance, role...
In 2016, South Africa became the first African country to draft Marine Spatial Planning (MSP) legislation. The underlying legal framework supports achievement of ecological, social and economic objectives, but a national policy grow oceans economy provides challenge for ecosystem-based approaches MSP. During 2018 International Conservation Congress in Borneo, we convened special session discuss particular challenges that will likely apply any developing seeking increase profits from...
Intertidal corals have been under-studied yet they provide scope for understanding adaptation and acclimatisation of to marginal conditions. Corals in intertidal rock pools along the east coast South Africa withstand large temperature fluctuations, conditions survival growth. Four sites KwaZulu-Natal (KZN) coastline were sampled determine latitudinal differences coral communities, from 27°S 31°S. Water at each site was monitored see if determined diversity pools. Sixteen species present...
Abstract Accurate assessments of ecosystem condition are needed to inform management processes such as systematic conservation planning and protected area expansion, marine spatial other effective area‐based measures. Yet measuring the dynamic often largely inaccessible ecosystems is extremely difficult presents a global challenge. Broad‐scale cumulative impact have been used in South Africa proxy for national reporting because data more readily available, knowledge exists on impacts various...
Despite the increasing number of tools and indicators to measure biodiversity status trends, many developing countries struggle initiate advance coastal marine assessments needed monitor track national international progress in targets. We identified five key challenges that hinder this context, based on a assessment workshop held South Africa, developed recommendations tangible actions address these drawing from multiple assessments, regional initiatives, global collaborations over last 15...
The need to move toward marine ecosystem-based management is globally recognized. Few countries effectively account for multiple interacting pressures in their assessments, planning and management. Many socio-economic sectors currently operate South African waters most cases, associated are managed on a sector-by-sector basis seldom accounted assessments or decision-making. For be effective, science-based approach prioritize needing urgent action, identify affected ecological components...
Baseline data for reference conditions are needed to determine the impacts of human pressures on structure and functioning marine ecosystems. However, baseline seldom available, a comprehensive understanding what good ecological condition is or how measure it often lacking. In absence true baselines, well established effective protected areas (MPAs) can be used approximate conditions. Thus, aim this study was use no-take MPAs identify suitable indicators that assessments rocky reefs in South...
