All in due Gorse…

Now that our busy summer season is over we Rangers can finally catch up with practical management tasks. Recently we have been carrying out Gorse removal on some of our SSSI Grassland.

Most people who visit St Abb’s Head will know that we have an extensive area of Gorse. In May/June, and to a lesser extent in late autumn, it’s at its most spectacular. The headland transforms into a vibrant yellow forest. Walking the paths around the Mire Loch you are hit with the sweet coconut scent of the blooms. As well as being visually spectacular it can also support a wide range of species, providing excellent ground cover for many mammals and birds.

So why remove Gorse…
Gorse is a strong plant and a prolific invader. If left unchecked it can quickly form a monoculture and take over large areas of open grassland. More sensitive species such as grasses and wildflowers find it impossible to grow as the Gorse forms a dense layer of needles and masks out the light.
During the summer our grasslands are abundant with wildflowers including Thrift, Wild Thyme, Common Rock-rose and rarer species such as Purple Milk-vetch and Spring Sandwort. This carpet of colour in turn provides food plants and nectar for a range of interesting butterflies and moths.
Our aim is not to remove Gorse completely but to prevent the plant from invading our Grasslands.

How do we remove Gorse…
Gorse can be removed relatively easily using a number of techniques. Our chosen method is to cut the Gorse at ground level, using loppers and bow saws, and to then treat the cut stumps with an approved herbicide. This method has the least impact on surrounding vegetation or on any archaeological features. We only carry out Gorse removal outside of the bird breeding season to avoid disturbing nests.
