Protect Our Fynbos: Stop the Black Wattle Invasion
Black Wattle (*Acacia mearnsii*) threatens Swellendam’s natural heritage, depleting our water catchments, increasing wildfire severity, and crowding out native Fynbos flora.

Black Wattle
Acacia mearnsii
- Leaves: Feathery, dark green bipinnate leaves with tight leaflets.
- Flowers: Pale yellow to golden spherical pom-pom clusters in late winter/spring.
- Bark: Dark brown/blackish, rough with high tannin content.
- Impact: Seeds remain viable in soil for decades; dense stands choke stream beds.
Sugarbush Protea & Ericas
Proteaceae / Ericaceae species
- Leaves: Broad, leathery leaves (Proteas) or tiny needle-like leaves (Ericas).
- Flowers: Vibrant bowl-shaped flower heads producing rich nectar for Sugarbirds.

Active Clearing Hotspots in Swellendam
Friends of Marloth Alien Plant Hacking
Friends of Marloth is a community organization that aims to build a strong connection between Marloth Nature Reserve and the Swellendam community and to provide practical assistance such as helping with maintenance of the reserve and fund raising. The alien hacking group meets on the second Saturday morning of every month to clear alien plants that are invading the reserve. In the summer they work in the cool of the kloofs to remove bleeding hearts, bugweeds, Australian cheesewoods and brambles in the indigenous forests. In winter they work on the warm sunny slopes to remove black wattles, pines and blackwoods. Volunteers have free access to enjoy the reserve for the rest of the day after hacking.
WhatsApp GroupSwellendam Conservancy
The conservancy promotes community action to achieve better environmental outcomes. It focuses on river systems and remnant veld around Swellendam. We try to solve problems through exciting solutions by bringing people and systems together to the benefit of man and beast.
Bethelskop
Bethelskop, also known as Heuningbos, is a small koppie of undiscovered nature overlooking Swellendam and its mountains. Nestled between Marloth and Bontebok Park, it is home to exquisite endemic Renosterveld and Fynbos. Since a 2021 fire, local residents have been actively pulling and popping invasive plants. Their dream is to reclaim and restore the area as a nature reserve for the Swellendam community, potentially linking all three areas into a biodiversity corridor. By sharing resources and tools and connecting with local conservation groups, the project hopes to inspire the community to protect and restore South Africa’s indigenous nature and heritage.
Masbiekerskloof Trail
MVP is the start of an indigenous green belt in the heart of Swellendam, a place of beauty for everyone! A community-supported conservation initiative focused on the removal and management of invasive alien vegetation within the Masbiekerskloof area, with the aim of protecting indigenous biodiversity, improving ecosystem health and reducing fireloads. The project forms part of an official Adopt-a-Spot Programme approved by the Swellendam Municipality for the period 2026 to 2028.
Clean and Clear on a Tuesday, 5–6 pm
Swellendam Hackers
The Swellendam hackers remove invasive alien plants, such as black and green wattles, port jacksons, Australian cheesewoods and others, from different public open spaces around Swellendam. Their work restores the natural vegetation of the municipal commonage for all to enjoy. They have a good collection of tools and knowledge to share with anybody interested in joining them. They meet at 5pm every Friday.
