Wide Variation in Post-Emergence Desiccation Tolerance of Seedlings of Fynbos Proteoid Shrubs ⁎ P.J
Available online at www.sciencedirect.com South African Journal of Botany 80 (2012) 110–117 www.elsevier.com/locate/sajb Wide variation in post-emergence desiccation tolerance of seedlings of fynbos proteoid shrubs ⁎ P.J. Mustart a, A.G. Rebelo b, J. Juritz c, R.M. Cowling a, a Botany Department, Nelson Mandela Metropolitan University, P.O. Box 77000, Port Elizabeth 6301, South Africa b Kirstenbosch Research Centre, South African National Biodiversity Institute, Private Bag X7, Claremont 7735, South Africa c Department of Statistical Science, University of Cape Town, Private Bag, Rondebosch 7700, South Africa Received 20 February 2012; received in revised form 13 March 2012; accepted 21 March 2012 Abstract Fynbos Proteaceae that are killed by fire and bear their seeds in serotinous cones (proteoids), are entirely dependent on seedling recruitment for persistence. Hence, the regeneration phase represents a vulnerable stage of the plant life cycle. In laboratory-based experiments we investigated the effect of desiccation on the survival of newly emerged seedlings of 23 proteoid species (Leucadendron and Protea) occurring in a wide variety of fynbos habitats. We tested the hypothesis that species of drier habitats would be more tolerant of desiccation than those from more moist areas. Results showed that with no desiccation treatment, or with desiccation prior to radicle emergence, all species germinated to high levels. However, with desiccation treatments imposed after radicle emergence, there were significant declines in seedling emergence after subsequent re-wetting. Furthermore, other than three species that grow in waterlogged habitats, germination responses could not be reliably modeled as a function of soil moisture variables. -

Common, are increasingly regarded sites for potential development. The Common has been the subject of debate during the last three years. The area has been identified as an urban open space containing highly valued natural and historical_-cultural assets. Significant areas such as this need to be protected from development and managed accordingly. They can be utilised as areas for environmental education, semi-formal recreation or aesthetic enjoyment. The Common typifies management problems that may be experienced in the compromise of using an area of predominantly natural vegetation for an unrestricted semi-formal recreation area. This report summarizes the importance of the Common and identifies the concerns surrounding its present management. -

Some pick flowers for markets to sell, some remove invasive alien plants, and Threats to fynbos 8 others are involved in conservation and nature tourism. It is important that people The value of fynbos 9 who work in the veld know about fynbos plants. This Field Guide for Wild Flower Harvesting describes 41 of the most popular types of fynbos plants that are picked from Fynbos and fire 9 our region for the wild flower market. It also provides useful information to support Classification of plants 9 sustainable harvesting in particular and fynbos conservation in general. Naming of plants 10 Picking flowers has an effect or impact on the veld. If we are not careful, we can Market for fynbos 10 damage, or even kill, plants. So, before picking flowers, it is important to ask: Picking fynbos with care 11 • What can be picked? The Sustainable Harvesting Programme 12 • How much can be picked? • How should flowers be picked?

Treatment of Seeds to Improve Restoration of an Endangered Mediterranean Climate Vegetation Type
Austral Ecology (2016) , – Heat and smoke pre-treatment of seeds to improve restoration of an endangered Mediterranean climate vegetation type STUART A. HALL,1* ROSEMARY J. NEWTON,2 PATRICIA M. HOLMES,3,4 MIRIJAM GAERTNER4,5 AND KAREN J. ESLER1,4 1Department of Conservation Ecology and Entomology and Centre for Invasion Biology, Stellenbosch University, Private Bag X1, Matieland, 7602, South Africa (Email: [email protected]), 2Conservation Science, Royal Botanic Gardens, Kew, Wakehurst Place, Ardingly, RH17 6TN, United Kingdom, 3Biodiversity Management Branch, Department of Environmental Resource Management, City of Cape Town, South Africa, 4Centre for Invasion Biology, Department of Botany and Zoology, Stellenbosch University, South Africa, and 5City of Cape Town, Private Bag X26, Tokai, Cape Town, South Africa Abstract Invasive alien plants impact ecosystems, which often necessitates their removal. Where indigenous species recovery fails following removal alone, an active intervention involving reintroduction of seed of native species may be needed. This study investigated the potential for a combination of the fire cues of smoke and heat as a pre-treatment of seeds in breaking dormancy and facilitating increased germination. Species were selected to represent different functional types within Cape Flats Sand Fynbos; a fire-prone, critically endangered vegetation type in South Africa. Seeds were exposed to either a heat pulse (tempera- tures between 60 and 300°C for durations of between 30 s and 20 min) or dry after-ripening (1 or 2 months at milder temperatures of 45°C or less). Thereafter, seeds were soaked in smoke solution for 18 h and subsequently placed on agar at 10/20°C for germination. -

Signed this day……20…… of ……November…….. 2017……. at ..........Bellville………… _____________________________ Signature i http://etd.uwc.ac.za/ ABSTRACT Research focused on ecological impacts and control of invasive alien species (IAS) is gaining attention worldwide. The eradication and control of invasive alien plants (IAP) is essential for the restoration of native plant communities. Understanding ecological impacts and potential invasive risks of IAP is important for their effective management, particularly for prioritisation. Most studies concerning impacts on vegetation structure and plant-pollinator interactions have measured few ecological metrics, resulting in a superficial understanding of plant species invasion. -
