Auchenreoch Glen
Auchenreoch Glen was created by a tributary of the Murroch Burn. It is particularly deep and steep-sided, and its southern wall, seen here on the left, remains in shade for much of the year (compare NS4178 : Lime-kiln ruin in lower Auchenreoch Glen), and is sufficiently steep as to be largely free of vegetation cover.
However, this allows the stratification of the rocks to be seen very clearly. These rocks provide a very fine example of the so-called Ballagan Beds, as explained at NS4178 : Ballagan Beds in Auchenreoch Glen, which also provides a closer look at these layers.

Is a deeply incised valley 1.5km south-east of Bonhill containing a rare habitat of plants and grasses.
Auchenreoch Glen is a deeply incised valley 1.5km south-east of Bonhill containing a rare habitat of plants and grasses due to its soil composition
The grassed slopes within the site support calcareous grassland and wet flushes. Calcareous grassland is a special type of habit associated with thin soil, such as chalk and limestone and is species rich. (L&G: Why is this important?) Plants on calcareous grassland are typically short and hardy and include grasses and herbs such as clover.
Auchenreoch Glen is notable for comprising two vegetation communities that are rare in Scotland.
On the more stable slopes, mainly in the eastern half of the site, the community is dominated by Wild Thyme. and false brome grass. It is surrounded by dense stands of bracken. (L&G: Brackens future impact?)
On the south side of the Glen, a grassland community of mouse-ear hawkweed exists. This is very rare in Scotland out with the south-east. Here it is at the extreme north-western limit of its range, being typical of chalk and limestone soils in England.
