Portlethen Moss is a protected lowland raised bog located near the town of Portlethen in Aberdeenshire, Scotland, known for its rare wetland habitats and diverse plant species.
Portlethen Moss Site of Special Scientific Interest (SSSI) is an important conservation area located just southwest of the town of Portlethen along the northeast coast of Scotland. This lowland raised bog is one of the few remaining intact examples of such habitats in Aberdeenshire, offering critical ecological value for peatland preservation and biodiversity. The moss is characterized by a mix of wetland vegetation, including sphagnum mosses, cotton grasses, and various sedge species, which create a unique acidic and waterlogged environment essential for specialist plants and invertebrates. The site plays a crucial role in carbon storage, providing natural flood mitigation and supporting a range of rare bird species such as the skylark and reed bunting. Human activity around Portlethen Moss has historically included turf cutting and grazing, but strict protection measures have helped to maintain the ecological integrity of the area. Though limited in formal recreational infrastructure, visitors can explore nearby public footpaths and enjoy birdwatching opportunities on the edges of the moss. The surrounding landscape offers coastal views and a chance to experience Scotland’s vulnerable peatland ecosystems. Educational signage highlights the importance of wetland conservation and the site's role in regional biodiversity. For naturalists and photographers, the moss provides a quiet, largely undeveloped setting to observe seasonal changes and springtime flowering of bog-specialist flora. Overall, Portlethen Moss SSSI appeals to nature enthusiasts interested in wetland habitats, conservation, and low-impact outdoor exploration close to the North Sea coast.
