Comment: The unit is part of a complex of shingle ridges. The shingle ridge topography has suffered significant damage in the past but there are parts that are intact. These are areas of good quality shingle ridge vegetation. The fossil geomorphology has been significantly disturbed through the construction of a narrow-gauge railway which has resulted in movement of shingle and irretrievable loss of ridge topography. There is localised, more recent damage around targets. However, despite this damage the ridge topography is still evident over most of the area. Vegetation is generally very sparse but the vast majority of the shingle is now undisturbed aside from around the training serials and showing signs of vegetation recolonisation. Where present the dry ridge vegetation is generally dominated by bryophyte/lichen mats with sea campion, sheep?s-bit, wood sage and sweet vernal grass. There are scattered patches of the dwarf form of broom. Gorse forms dense patches in the north eastern part of the unit close to the road and could in the future cause loss of shingle vegetation. Vegetation along the eastern margin is of interest in having a calcareous aspect with carline thistle, yellow oat and lady?s bedstraw. The rare plant red hemp nettle was noted in the south east corner and dwarf mallow is present. No exotic species which might have adverse impacts were noted. This unit has also been surveyed in detail in 2009 for great crested newt and found in favourable condition to support great crested newts.
