Brown Moss of breeding birds at the site and many visitors, including wetland birds, such as Canada goose, mallard and great crested grebe. During the summer, froglets and dragonflies are found around water and woodland edges. Brown Moss is a flat site that was created at the end of the last Ice Age, over 10,000 years ago. As glaciers retreated, pools were formed by the stranded ice rocks, forming kettle holes Peat is still being created and Sphagnum moss – which is very important for the creation of peat – is found in abundance. This site contains a number of circular walks
Portlethen Moss lower elevations in every direction. Due to the high winds, moderate precipitation and cool temperatures that generally prevail, conditions are favourable for formation of an acid bog, since water stagnates, but eventually evaporates with ensuing acidity enhancement of decaying organic matter. There was virtually no drainage outlet in prehistoric times, and little drainage even in modern times. Many coastal mosses were initiated by the process of glaciation, which sheared rock formations to a generally level terrain, while also gouging moderate sized craters that would pond. This description fits the fundamental situation of Portlethen Moss, where sphagnum would have flourished over
