Congruence between plant and insect diversity is considered possibly useful in conservation planning, as the better known plants could be surrogates for the lesser known insects. There has been little quantification of congruence across space, especially in biodiversity rich areas. We compare here species richness, and turnover relationships between plants and flower-visiting insects across space (0.5–80 km) in natural areas of a biodiversity hotspot, the Greater Cape Floristic Region, South Africa. A total of 22,352 anthophile individuals in 198 species and 348 plant species were sampled. A comparison between the plants and anthophiles suggest significant concordance between the two assemblages. However, turnover was weaker in plants than in anthophiles. Plant turnover decreased with greater geographical distance between plot pairs. In contrast, insect turnover remained high with increasing geographical distance between plot pairs. These findings suggest that while patterns of plant diversity and distribution shape flower-visiting insect assemblages, they are not reliable surrogates. The conservation significance of these results is that specialist mutualisms are at greatest risk, and that set-asides on farms would help improve the functional connectivity leading to the maintenance of the full range of mutualisms.

Cultivation has been the primary driver of habitat transformation in South Africa. This paper explores the effectiveness of agricultural and, latterly, Environmental Impact Assessment (EIA) authorisation procedures in stemming biodiversity loss resulting from cultivation in the lowlands of the Cape Floristic Region, a global biodiversity hotspot. Owing to an activity-based focus, agri-environmental regulation has been largely unable to mitigate the cumulative effects of large-scale land clearance in threatened ecosystems. Case studies in the Sandveld and Slanghoek districts are used to argue that revised EIA regulations published in 2006 partly perpetuate the structural shortcomings of activity-based EIA. An ecosystem-based strategy for agri-environmental screening in biodiversity hotspots is introduced, drawing on conservation plans, the agricultural LandCare programme and the provision for Environmental Management Frameworks (EMF) in the 2006 EIA regulations. "Agri-EMFs", as a collaborative initiative that involves government, agricultural and non-governmental representatives, may present an effective alternative to the inefficiencies of project-level EIA.

The City

Cape Town is a fast-growing cityscape in the Cape Floristic Region in South Africa with 24 formally protected conservation areas including the World Heritage Table Mountain National Park. These sites have been protected and managed as critical sites for local biodiversity, representing potentially one-third of all Cape Floristic Region flora species and 18% of South Africa’s plant diversity. Cape Town is also inhabited by a rapidly growing culturally and economically diverse citizenry with distinct and potentially conflicting perspectives on access to, and management of, local natural resources. In a qualitative study of 58 locally resident traditional healers of distinct cultural groups, we examined motivations underlying the generally illicit activity of harvesting of wild resources from Cape Town protected areas. Resource harvester motivations primarily link to local economic survival, health care and cultural links to particular resources and practices, ‘access for all’ outlooks, and wholesale profit-seeking perspectives. We describe these motivations, contrast them with the current formal, legal and institutional perspectives for biodiversity protection in the city, and propose managerial interventions that may improve sustainability of ongoing harvest activities.
