crotalophoroides Walter--BULBOUS ADDER'S TONGUE FERN. Figure 8e, 8f.
This is great news for rare plants such as the green-winged orchid and adder's tongue fern, as well as the battalions of crickets, butterflies, bumblebees and other invertebrates that thrive in the High Weald grassland, and which, in turn, attract and support birds and mammals.
These include grasslands which have not been subject to artificial fertilisers and are home to meadow flowers and plants such as adder's tongue fern, which grows a single oval "leaf" every year, encasing a tongue-like spike.
