The GCV were formed in 1996 and since then they have worked hard to conserve Guernsey’s environment. Tasks the GCV undertake include reed bed clearing, tree care and removing invasive species, with Sour Fig eradication being one of their key projects. This is the second year the GCV have joined forces with us against Sour Fig. However, they have travelled over before to help with other tasks (such as tree planting).

Sour Fig is a species of succulent plant which is native to South Africa, with it first being recorded in Alderney in 1953, although its introduction is believed to be earlier. While it can be considered a ‘pretty’ plant with a pink and yellow flower, it is also one of the biggest threats to Alderney’s coastal habitats. The species is also a leading threat to Guernsey’s natural world (with it being introduced to the island in 1886 as a garden plant).

Sour Fig is a flat-growing plant which threatens other species by forming dense mats, making them hard to penetrate, and also spreads easily. New patches can grow quickly from small pieces of the stem. Sour Fig threatens Alderney’s coastal grasslands, home to many native wildflowers and grasses including the endemic Alderney Sea Lavender.

As someone who hasn’t been to Guernsey (if you don’t include the brief reroute during a windy flight from Southampton to Alderney), it was fascinating to discuss with the GCV about other threats that their environment faces and the actions they take to help protect it. Another invasive species that is present in Guernsey (but hasn’t been recorded in Alderney) is Cape Ivy, a plant species originating from South Africa which grows in thick masses, preventing native plants from growing. It can also be toxic to some animals and is one of the GCV’s main focuses next to Sour Fig.

I noticed that not only did we share a passion to help our natural world, but a commonality we seemed to have was the benefits we find as individuals when being outside. This included stepping away from technology, socialising with like-minded people and getting physical exercise. One member of the GCV summarised this last point perfectly: “It’s cheaper than the gym”. And it certainly is!
