Elim Conebush (Leucadendron elimense)
Mohamed bin Zayed Species project number 182514153
Safeguarding keystone fauna and flora on the Agulhas Plain, South Africa
Farm 215 as an example of a conservation servitude and the impact on critically endangered endemic cone bushes
The Agulhas Plain region has been identified as a biodiversity hotspot, with unique life and high endemism. Nestled in the heart of this region, is the Walker Bay Fynbos Conservancy (WBFC) - a conservancy dedicated to the conservation of the Cape Floral Kingdom. The WBFC was established in 1999 and recognizes the importance of a collaborative effort in conserving and managing the landscape. Currently the WBFC consists of 34 landowners, covering an area of 18 000 hectares of a wide variety of vegetation types. With 80% of the biodiversity of the Cape Floral Kingdom occurring on private land, it is vital to work with private landowners in order to conserve this biodiversity. Over the past 19 years, more than 1 100 plant species have been photographed and documented in the region (12% of the diversity of the Cape Floral Kingdom). As a long standing member of the conservancy, Farm 215 is dedicated to the conservation of fynbos and in its own capacity has funded the removal of some alien invasive plant species from part of its land. The owners have also photographed and documented all plants through the various flowering seasons.
Elim ferricrete fynbos has been classified as critically endangered due to the high threats this vegetation faces from alien invasive plant species, land transformation, agriculture and poor fire regimes. While fynbos is typically categorised by low nutrient soils, Elim ferricrete soils are more fertile and productive, giving rise to the threat from agriculture. With very little of this vegetation type formally conserved, it is vital to create awareness and educate the landowners of the biodiversity on their land. The Grootbos Foundation aims at mapping all remnant patches of this vegetation type on the Agulhas Plain. While original estimations were suggested at 25% of this vegetation type remaining, our current research is proving that there is a lot less of it remaining. Preliminary research suggests that there is as little as 5% of Elim ferricrete fynbos left intact. Once mapping is completed, the Grootbos Foundation will feed this data to the South African National Biodiversity Institute (SANBI) for the South African national vegetation map. All sites are categorised by the condition of the vegetation as well as the alien invasive species density, giving each site a score out of 10.
The ultimate goal in conservation is to conserve land in perpetuity, ensuring the conservation of landscapes, biodiversity and important ecological corridors for the movement of fauna and flora. While there will always be an on-going struggle to find the balance between conservation and livelihoods, it is extremely important to secure vital linkages and corridors in the landscape to ensure our biodiversity doesn't diminish. Conservation servitudes are a legally binding layer added to the title deeds of a property, ensuring that no further development or degradation occur on that land. While the conservation servitude property still belongs to the landowner, a conservation layer is added to the property and is applicable to both current and future landowners.
At Farm 215, an original 7-hectare area of critically endangered Elim ferricrete fynbos, has now been expanded to 585 hectares of the land successfully signed into a conservation servitude as a result of this Project. While focus is still predominantly on the management and rehabilitation of the Elim ferricrete fynbos, there are also large expanses of critically endangered Overberg Sandstone fynbos conserved through thisservitude status. Through this servitude, we were able safeguard a population of the locally endemic Aloe juddii. The Aloe juddii is listed as an endangered species and can only be found in the rocky outcrops from Gansbaai to Baardskeerdersbos at three known sites. This is a huge milestone for conservation and ensures the conservation of landscape connectivity between sites.
The Grootbos Foundation is currently working with the neighbours of Farm 215 to ensure a further conservation corridor is secured linking state conservation land on the coast at Walker Bay Nature Reserve to state conservation land on the eastern side of Uilkraalsmond Nature Reserve. The Grootbos Foundation developed a full Management Plan for the servitude area on Farm 215 which outlines all management activities for the farm. The management plan is attached to the legal documents and acts as a framework for permitted activities in the area; it also includes species lists, alien invasive mapping, fire protocols and trail mapping.
There have been various projects undertaken at Farm 215 to restore the Elim ferricrete area through intensive alien clearing as well as a rehabilitation project by which endemic species to the Elim veld have been planted back into the site. With the generosity and support of the Mohamed bin Zayed Species Conservation Fund, we have been able to provide the landowner with further alien clearing on the sensitive vegetation site. As this land is conserved in perpetuity, return on investment is high. The alien clearing project provides training and employment to a team of twelve women from the local underprivileged community. As the vegetation is extremely sensitive, the alien clearing is labour intensive and requires skill and precision. Fixed point photography sites have been put in place across the site to monitor the recovery of the land after the removal of alien plant species.
Through previous poor fire regimes and overgrazing, populations of the endemic cone bushes have suffered significantly on Farm 215. These endemic cone bushes are of conservation concern and have been listed on the SANBI Red Data List. The Grootbos Foundation collected seeds from the endemic cone bushes; namely Leucadendron elimense (Endangered), Leucadendron modestum (Endangered) and Leucadendron laxum (Endangered), for propagation at the Green Futures Nursery located on Grootbos Private Nature Reserve. The Green Futures Nursery is one of many socio-development projects implemented by the Grootbos Foundation, as has been in operation for fifteen years, providing training and skills development to members of the local communities in horticulture and hospitality. Once these seeds germinated, the seedlings were planted back into the site on Farm 215 in five trial blocks. The 10mx10m blocks were carefully selected in the area of disturbed land where various planting methods could be trialled for succession of plants. Broad cast seed sewing and planting of seedlings were trialled in the various blocks and are being closely monitored. After the Spring months, plant population succession will be documented allowing one to see which method is most viable.
Farm 215 has been a catalyst for conservation in the area and in August 2018, the Grootbos Foundation signed their second conservation servitude with Lomond Wine Estate which borders onto Farm 215. Conservation servitudes are a relatively new form of conservation which allow landowners an easily accessible opportunity to conserve their land.
Agulhas Green Corridor Project Goals:
1. To determine the distribution and extent of all remaining critically endangered Elim fynbos patches as well as other threatened vegetation types in the corridor area and to prioritise these for conservation intervention.
2. To map the distribution and determine the population sizes of the four flagship Elim fynbos species.
3. To meet with and inform landowners about the occurrence of Elim fynbos and flagship species on their properties. To use these findings to strengthen our case for conservation and excite landowners with regards the unique biodiversity value of natural habitats on their properties.
4. To meet and interact positively with landowners to start the process of strengthening their conservation commitment both through increased knowledge and awareness as well as through incentives and exploring the option of conservation easements.
5. Establish servitudes (easements) on private land and provide owners with management plans which will focus on stock exclusion, alien vegetation management and fire management.
6. Provide incentive activities (alien vegetation clearing, fencing) for partner landowenrs who commit their priority sites to conservation.
7. Propagate four target species and reintroduce to priority sites as part of site rehabilitation projects - implement though our Green Futures programme that provides livelihoods for local disadvantaged communities.
