Since 2022, with the support of Swellendam Municipality, we have been hard at work with alien clearing projects in the towns of Swellendam and Barrydale. Our efforts within the towns have resulted in the initial clearing of 243 hectares, with follow-up maintenance on an additional 177 hectares. This monumental task will not only rejuvenated the landscape but has also provided a total of 4000 days of employment for local communities. We're proud of this achievement and grateful for the ongoing support of our funding partners. Focus on Riparian Zones Our attention has now shifted to the riparian zone of the Koringlands River through Swellendam. This vital ecosystem requires delicate care to thrive, which is why we're committed to removing alien invasive species that monopolise water resources. By clearing these intruders and allowing natural vegetation to flourish, we're not only preserving biodiversity but also restoring the balance of these critical areas. We also have a monitoring programme to understand how this clearing improves the status of the river. Funding for these projects comes from the Swellendam Municipality, dedicated landowners, and the Breede Gouritz Catchment Management Agency. We have a similar project in place to restore the Huis River in Barrydale so watch out for news of that soon. As stewards of the land, it's our privilege and responsibility to protect the natural wonders that surround us. Our focus lies in minimising fire risks and controlling sparsely invaded regions, ensuring that the hard work of alien clearing isn't undone. Through our ongoing efforts in alien clearing and riparian zone restoration, we're working tirelessly to uphold this commitment. We extend our heartfelt thanks to our funding partners, landowners and contractors who make our conservation endeavours possible.
Together, we're not just clearing aliens; we're cultivating a future where nature thrives and continues to provide the ecosystem services that we all depend on. Stay tuned for more updates on our conservation activities, and let's continue to make a positive impact on the world around us.

As we find ourselves well into the swing of 2024, its time to provide an update on the exciting projects keeping us busy. One of our key focuses has been Environmental Education, aimed at fostering a love for nature and a sense of responsibility for our environment among young minds. Here's a glimpse into what we've been up to. Over the past few months, we've had the pleasure of visiting three schools where we reached over 200 children: De Waaville Primary School, Mullersrus Primary School, and Vondeling Primary School. These visits weren't just routine outings; they were immersive experiences where students got hands-on with conservation efforts. Our environmental education program isn't just an add-on; it's integrated into the Grade 7 Natural Science curriculum. By taking learning outside the classroom, we provide students with practical insights into the importance of preserving natural habitats. From removing invasive species to planting indigenous flora, every activity is designed to instill a sense of stewardship towards our environment. Beyond teaching theoretical concepts, we emphasised actionable steps that students can take to make a difference. Whether it's river monitoring or simple acts like picking up litter, we empower young minds to become active participants in conservation efforts. After all, small actions can lead to big changes. During these visits, we don't just educate; we also collect valuable data. Mini SASS results gathered from the field are fed into the database, contributing to broader efforts to understand the state of our rivers. None of this would be possible without the support of our funder #Landcare from the Department of Agriculture who are committed to these projects. We are also grateful to the Gouritz Cluster Biosphere Reserve, who assisted with womanpower(!) on the day. We also very grateful to Michelle and Keith Moodie who supplied an amazing packed lunch for 200 children (that's a lot of sandwiches to make!) To the schools that welcomed us with open arms, we extend our heartfelt gratitude. Your enthusiasm fuels our passion for environmental education. As we move forward, we're excited about the prospect of expanding our reach and touching the lives of even more young learners. After all, our motto remains steadfast: "If we can teach another person at least one new thing, then we have done our job." As we reflect on the busy start to this new year, our commitment to environmental education continues. With each school visit, we sow the seeds of conservation, nurturing a generation of eco-conscious citizens. Thank you to everyone who has supported our endeavours, and here's to many more initiatives. Together, we can make a difference—one student at a time.
As we reflect on World Wetlands Day, we're thrilled to shine a spotlight on the lifelines of our region – the five main river systems that we are dedicated to protecting and restoring. These rivers, each intertwined with a rural town, not only provide water for human consumption but also sustain our rural agricultural economies. Join us on a journey through these ecosystems and consider how you can help to protect these systems for future generation. The Huis/Tradouw System Supporting Barrydale and SmitsvilleThe Huis/Tradouw System originates in the Langeberg mountains above Grootvadersbosch. The river meanders down the northern side of the mountains and provides water for Barrydale/Smitsville and then flows into the Tradouw Pass. Home to the critically endangered Tradouw Redfin and freshwater eels, our team is actively monitoring and restoring this system under a new project funded by the IUCN. The Duiwenhoks System Supporting HeidelbergThe Duiwenhoks river winds through the kloofs of the Grootvadersbosch Nature Reserve, providing water for Heidelberg and eventually embracing the ocean at Vermaarklikheid. Our commitment to the upper section involves clearing alien vegetation, monitoring, and collaborating with partners, ensuring it remains a lifeline for agriculture and the town of Heidelberg. THe Korente-Vette River System supporting RiversdaleIn a transformative project, we've joined forces to clear the natural river gorge below the Korentepoort Dam. This collaborative effort enhances water supply to the town of Riversdale and supports agriculture by meticulously removing invasive plants with complex rope access teams, a strategically important project, achieved in partnership with Landcare and the Korente Vette Irrigation Board. The Koringlands River supporting SwellendamCelebrating the beauty of the Koringlands River in the heart of Swellendam, we're working to remove alien vegetation and restore natural wetlands. In collaboration with Swellendam municipality, the Breede-Olifants Catchment Management Agency, and landowners, we hope to transform this vital system and improve the health of the river and the surrounding ecosystem. The Grootvadersbosch River supporting SuurbraakThe Grootvadersbosch River is the lifeblood of our community, supporting agriculture and flowing through the heart of our Conservancy. With thriving indigenous fish, diverse birdlife, and ongoing efforts to clear invasive species, we're committed to safeguarding and nurturing this precious resource for generations to come. On this World Wetlands Day, we invite you to explore the rich tapestry of our rivers and wetlands. If you're inspired to support our work or learn more about your local river and wetlands, please visit our website:

Over the last 6 months, the Grootvadersbosch Conservancy Team has been involved in a series of environmental education days that are important to create future environmental leaders. These programmes include educational nature walks where we focus on explaining how unique our environment is, our different vegetation types (fynbos, forest and thicket pockets) and why we need to protect our rivers. On these walks we also talk about why we do alien clearing, how we do it and why it is necessary to remove alien, invasive species. We also focus on the protections of our river systems. We teach children about our unique Barrydale Redfin, which is a critically endangered species only found in the Huis River System. We monitor our river systems by implemented SASS and we share this experience by doing a mini-SASS. This activity lets them experience and observe all the tiny micro-invertebrates up-close and see both the invasive and indigenous fish species in our river systems. The schools that we have done environmental education days with this year include:
At the end of these events our team always appreciates how import and difficult a task it is to be a teacher. We really love these days and know how important they are for our collective futures. We are excited to be doing more of them… but we are also very glad that its not all we do because its hard work!
We salute the teachers out there and hope that you have a lovely Christmas Break! Our Grootvadersbosch Dwarf Chameleon records are accumulating! Krystal Tolley visited our valley during this year's Silver Mountain Music Festival, where she gave a fascinating talk about the chameleon species and talked more about her book (link below if you want to check it out!). She was also here to do some further surveys and recordings of her chameleon findings and took beautiful photographs of the extraordinary petite species. The data results indicate that Dr. Tolley found male and female individuals as well as juveniles, thus we can assume that their population is steadily growing thus we need to continue in protecting our Afromontane Forest region here in the valley! All images were taken by Krystal Tolley. If you want to support her and buy her Chameleon book then please visit here. REFERENCES:
Tolley, K.A. 2022. Bradypodion venustum. The IUCN Red List of Threatened Species 2022. Available at: https://www.iucnredlist.org/species/214766876/214766885 Earlier this year the Conservancy held its annual AGM where we celebrated an important achievement as an organisation - our FIRST internationally funded project! We were privileged to have Trevor DeRuisé with us from Lost Boy wines who’s gorgeous “wines from the wild” were a perfect accompaniment to our important AGM. At the AGM we introduced our members to our exciting new restoration project, funded by the INTERNATIONAL CLIMATE INITIATIVE GRANT (IKI), also known as the IKI Small Grants Programme. The IKI Grant is implemented by the Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH and focuses on climate change mitigation projects and on biodiversity and forest conservation. ABOUT THE NEW PROJECT The conservancy has always focused on alien clearing projects to aid the natural environment and create employment in the surrounding communities. We will continue to do this work but, through the IKI Grant, we can take this work a step further. In most cases, on-going alien clearing is the most cost-effective approach to restoration. However, in some cases, the removal of invasives can result in open and bare ground, with little to no regrowth of plant species. This will increase the risk of erosion and the regrowth of aliens. This often occurs in highly disturbed areas that do not have natural seedbanks or where the seedbank might be from garden plants that may not always be ideal to re-establish in cleared areas. In these conditions, the natural environment struggles to adequately restore itself and would take twice as long. In these cases, nature benefits from a helping hand or a ‘hup-stoot’, as our new restoration manager, Corné Brink puts it. This project will allow us to combine alien clearing with forest restoration activities in specific areas. This project is a 2-year contract and will focus on establishing the nursery facilities for restoration, developing the skills needed and promoting restoration activities. We have selected two demonstrate sites where we can test approaches, develop standards, and train our alien clearing teams in restoration techniques. The project has a large emphasis on capacity building, and job creation in rural communities. For this project, we will need a large number of indigenous plant species, ranging from ground covers, shrubs, and trees. This is only possible by establishing our own propagation facility where we can learn how to propagate the wide array of plants that represent the diversity of the Grootvadersbosch flora. To make this project a success, we will work closely with landowners to responsibly harvest plant material so that our sites closely match the local genetic plant material. For each of the restoration sites, we have selected a reference site which helps to guide what plants should be represented on the restoration sites.
In the long term, the nursery may eventually become a source of revenue for the conservancy so that we can continue to sustain our alien clearing activities that are still reliant on a government funding. Much like in nature where diversity is crucial for sustainability, diversity of funding sources is also important to secure the future of the conservancy. This project will allow the conservancy to build capacity, diversify income sources, and increase the skillsets of the local communities surrounding the Grootvadersbosch Conservancy. This will be done by employing more workers and providing training in ecology, restoration activities, and methods of propagation of indigenous species. Through this project, we are also engaging with other restoration professionals to build our collective understanding of how we can improve the effectiveness of restoration projects in the Western Cape as a whole. The IKI project will be implemented by Corné Brink who joins us from the Garden Route Botanical Gardens in George. Corné has a background in conservation, guiding and endangered species rehabilitation. Her experiential knowledge of successional ecology and the different techniques and styles of ecosystem restoration, along with her style of implementing holistic practices through scientific methods will assist in pioneering a standard for ecosystem restoration in Afromontane forest, fynbos and renosterveld in the region. She will be assisted by Goliath (Twakkie) Highburg and Jessi Venter. Oom Twakkie has incredible knowledge of the Grootvadersbosch flora region and has a natural ability to grow anything put in front of him. He has incredible local knowledge to share with the restoration team and we would be lost without his wisdom and work ethic. Jessi is our Nature Conservation student intern, who will soon be graduating, but staying on as a vital part of our team. She has always had a passion for conserving nature and she is extremely excited to finally live out this passion with our new Restoration Project. She is also our Social Media Content Creator and combines her love of photography with incredibly stories from the many GVB expeditions. Now that Oom Twakkie is more involved in the restoration project, Ricardo (our alien clearing manager) needs more assistance with the ever growing alien clearing projects. This has allowed us to bring in Mzomhle Mtshintshi who has a background in forestry and is taking on the Quality Controller role (with the odd trip to the river for fish monitoring!). We are excited about the many new opportunities that this project will bring to the conservancy and to the area as a whole. Thank you for your support HOW CAN YOU HELP?
Donations of 🌼 White Yogurt Tubs 🌼 Dark yogurt Tubs 🌼 5l Ice Cream Tubs 🌼 Cardboard boxes 🌼 Newspaper would be greatly appreciated! And any donations of indigenous plants and equipment will also be appreciated! Thank you to everyone's continuous support for our work It was with great pleasure that the Grootvadersbosch Conservancy got the opportunity to collaborate with the South African National Biodiversity Institute (SANBI) in their mission to collect and conserve seeds from our region to preserve them for a lifetime in the Millennium Seed Bank Partnership (MSBP). The MSBP is an international program where the main goal is to collect and conserve seeds on a global scale, with over 80 countries involved, including South Africa. The MSBP banks the collected seeds at the Seed Conservation Department at the Royal Botanic Gardens (Kew) where the seeds are dried and kept in freezers under -20°C. These conditions make it possible for the seeds to stay viable for hundreds of years and be available to use when necessary. The aim of the Millennium Seed Bank Partnership is to collect all plant species for ex-situ conservation and storage in the long term. Priority is given to the protection of threatened plant species to reduce the possibility of total extinction. Field trips and pre-preparations are vital in planning and implementing the collecting of specimens and seeds, targeted species should be determined beforehand, and the team should also be prepared to collect specimens that were not on the targeted list. This will ensure an effective and successful field trip. There are multiple collection techniques that can be used when collecting:
THE MISSION On the 6th of June, the Grootvadersbosch Conservancy team joined SANBI for the collection of specimens and seeds of the outstanding species that needed to be collected. The SANBI project is led by Naomi Mdayi and Sibahle Gumede with Yandisa Ndzeku (photographer and collector), Michael Ndovu (photographer and collector), Sihle Mvunyiswa (collector), and Sphephelo Kheswa (collector). They were joined by Goliath Highburg, Jessi Venter, Bella Liebenberg, Rachel Jacobz, and Marius Piek from the Conservancy to assist with local knowledge. We started our journey in the Grootvadersbosch Nature Reserve Forest area where most of the forest-targeted species can be found. Our journey did not go on too long before we spotted the first plant species to collect for the day. The team identified the species together (with the help of reliable identification elements) to ensure that it was the correct species. Naomi and Sibahle filled in the required data in the standard MSBP data sheet that records all the details of the species and its surrounding environment – soil characteristics, geology, slope aspect, and altitude. These are recorded for future restoration implications. It is a time-consuming process but essential to complete onsite to avoid any details being missed. Yandisa Ndzeku, Michael Ndovu, Sihle Mvunyiswa, and Sphephelo Kheswa oversaw the collection of two herbarium specimens for each species collected and of viable seeds where possible, using the previously mentioned collecting techniques. The collected specimens were temporarily put into plant specimen collecting bags and were later pressed in herbarium plant drying pressers. These steps were followed throughout the day’s journey, with the Grootvadersbosch Conservancy team assisting in the identification of plant species and the carrying of specimens. Specimens collected were as follows: Anemone vesicatoria – Blisterleaf – Brandblaar Scolopia mundii – Red pear - Rooipeer Podocarpus latifolius – Real yellowwood – Opregte geelhout Canthium inerme – Common turkey-berry – Gewone bokdrol Ilex mitis – African holly - Waterboom Chionanthus foveolatus – Pock ironwood – Pokysterhout Phylica pinea – Pine Hardleaf Elegia racemosa – Restionaceae After collection and identification, the specimens are prepared for the herbarium. The process involves carefully placing the plants in a press with layers of press paper, to absorb any excess moisture from the species. This is important to make it a perfect pressed herbarium specimen. Once dried, it will be removed from the press, labelled with other associated data of the collection, and submitted to an Herbaria to confirm that all the data are correct before it is shipped to the MSBP and Royal Botanical Gardens. Thank you to the Grootvadersbosch Conservancy team. Their contributions were so instrumental in helping us to achieve our goal. They were willing to go above and beyond to ensure the smooth execution of the project. We were thoroughly impressed with their professionalism, dedication, and expertise throughout the entire process. It was a great pleasure working with them, and we look forward to collaborating again in the future.” from Sphephelo Kheswa, SANBI. REFERENCES:

The Grootvadersbosch Conservancy has worked on the removal of Pereskia aculeata over the past few years and knows how problematic an alien invader it is. The conservancy used to burn off every stem of the plant which was quite an expensive process. The Grootvadersbosch Conservancy has been working with the Swellendam municipality to manage alien invasives and noticed an invasion in the centre of town. We urgently required an easier way of eradicating the pesky Pereskia, so we contacted Dr. Iain Paterson to aid us with some biocontrol. He posted the biocontrol to us where we could release it at two sites – the first site is at a Swellendam municipality near the mall and the second site is at the Buffeljags Dam. what is pereskia?Pereskia aculeata originates from Brazil in South America and thus it has no natural predators in South Africa. It is a creeper plant that can easily outcompete and overgrow indigenous plants especially in forest and plantation areas, leaving them with no access to sunlight, natural pollinators, and water (Invasives SA, 2014). The spread of Pereskia aculeata is problematic as the areas with the infestation will become degraded and will have little growth of indigenous plant diversity over time. what is biocontrol?Biological control (Biocontrol) is the use of a natural enemy, usually an insect or pathogen, to control and/or eradicate an alien invasive plant species (ARC, 2014). Biocontrol is an alternative method to control and eradicate alien invasive plant species and is very effective and often used in combination with mechanical control Luckily for this Pereskia invasion, both biocontrol agents were delivered to us, Pereskia Flea Beetle (Phenrica guérini) and Pereskia Stem-wilter (Catorhintha schaffneri). We released both at the Swellendam municipality site and only the Pereskia Stem-wilter at the Buffelsjag Dam site. Both agents can only survive by feeding on Pereskia. The Pereskia Flea Beetle feeds on the leaves, forming big holes while leaving a trail of brown faeces. The Pereskia Stem-wilter feeds on the plant shoot tips, splitting them open and/or rotting them. We are very grateful for the incredible scientists who work so hard in developing these agents and so we decided to interview Dr. Iain Paterson who shares his experience in developing a biocontrol agent for Pereskia aculeata. how and when did you start working on biocontrol for Pereskia aculeata?Dr. Paterson has always had a passion for nature, he loved plants and animals since childhood. Once he started university, he decided to study both Zoology and Botany. While studying, he discovered an interest in insects, he was fascinated by the idea of using insects as a biocontrol agent, consequently, he decided to pursue Entomology and he then did his Ph.D. on Pereskia aculeata. What is the process for developing a biocontrol and what beetle species are used to combat the alien, invasive Pereskia aculeata?Dr. Paterson explained that they experimented with potential Biocontrol insects, which are all indigenous to South America. Five insects were used in the experiment and only two were found successful as a biocontrol. It took him 2 years to prove that the Pereskia stem-wilter beetle (Catorhintha schaffneri) will only feed on Pereskia aculeata and not on any other indigenous plants of Africa. Why is it so important to develop a successful biocontrol for Pereskia aculeata?Pereskia aculeata is an alien-invasive vine plant species. Vine plants are almost impossible to remove successfully using chemical or mechanical methods without damaging the surrounding indigenous vegetation. Pereskia aculeata also has a nasty habit of resprouting where it has broken off and any present stem fractions will eventually develop into a new plant. Dr. Paterson once brought a Pereskia stem fraction from overseas within a clip file and, with no soil or water, the fraction grew leaves, displaying its remarkable survivability and durability. Why does the Pereskia stem-wilter only feed and survive on Pereskia aculeata?In general, insects are selective feeders, they always seek and select the plants with the most nutrients that their bodies can absorb. In their natural habitat, the Pereskia stem-wilter evolved by only feeding on Pereskia. Here in Africa none of our insects are familiar with Pereskia aculeata and will not feed on them. Without natural pests, Pereskia will outcompete our indigenous plant species and spread rapidly. In what way can the public assist in reducing the spread of Pereskia aculeata?The public is advised to learn how to identify Pereskia aculeata and not to plant and grow it within their gardens. In the past, Pereskia was used as a hedge plant in the garden because it grows so effortlessly. If the Pereskia aculeata is removed by hand, all the biomass that is removed and disposed of will resprout. Wherever it ends up, it will create a new infestation so it is advised to let the biomass dry out, or even better, spray it with herbicide and once it turns brown, it should be burned. What should we, the conservancy and/or the public, keep in mind when using Pereskia biocontrol?Dr. Paterson states that the Pereskia biocontrol will not immediately eradicate the whole alien plant, the beetles must first establish their population. Once established, the Pereskia infestation will slowly deteriorate over time as the beetles feed on the shoots and roots. This will decrease the spread of the plant and reduce the Pereskia infestation. How can we obtain the biological control for Pereskia aculeata?The biocontrol is funded by the Department of Fisheries, Forestry, and the Environment (DFFE) and is provided by the Centre for Biological Control (CBC) of Rhodes University. The Grootvadersbosch Conservancy can also be contacted if Pereskia is observed so we can track its spread and the success of the agent in its control. With the help of Dr. Paterson and the biocontrol agents, we are doing all we can to remove Pereskia aculeata!
We thank Dr. Paterson for his time and knowledge regarding Pereskia aculeata and the tremendous journey in creating a biocontrol agent! |
