Lying between the 13th tee and the 14th green, Sanctuary 14 is a significant block of cork oak woodland with a bramble under-storey that grades into low shrubs and ornamental plantings on its northern side. The land slopes gently east and is divided by two sandy service roads in which animals frequently leave their tracks.

25 species of the pea family can be found in Sanctuary 14, more than anywhere else on the course. Because peas and their relatives can extract nitrogen from the air with the help of bacteria, their abundance suggests that the soil is naturally poor here, leading to less competition from other plants.

Butterflies are beautiful and fragile insects with wings that are far larger than needed merely for flying. They are also used as solar panels for warming the insects flight muscles, and as signals, hence the colours and patterns.

Because of the disproportionate size of their wings, butterflies are vulnerable to damage in wind. Accordingly, most species seek the shelter of woodland. A third of the species found on the whole course occur in this sanctuary.
