The Elrick Burn flows from urban Westhill, through industrial and agricultural land, into the Brodiach Burn some 3km south of its source. Along its course the culverted Elrick Burn flows past Arnhall Moss, the main focus of wildlife within the catchment.

Arnhall Moss is a raised bog, a moss, which owes its origins to impeded surface drainage. It is one of only a few remaining lowland bogs. The area contains a wide diversity of wildlife and habitats for such a small area. Habitats include a variety of woodland types, scrub, grassland, wet and dry heaths, and wetland. The range of habitats has led to the area being designated as a Local Nature Reserve (LNR). To find out more about Arnhall Moss, select this link.
