CFSS was founded in 1970 after attempting to revive the Alloa Society of Natural Science and Archaeology established in 1865. The society's aims are "to promote interest in the environment and heritage of the local area" and we have some 120 members.

In winter, from September to April, there are fortnightly lectures dealing with varying topics and a member's night. The season begins with a coffee morning and concludes with our AGM. In summer, walks may be organised.

CFSS has run and participated in various events e.g. Industrial Archaeology, David Allan and at Alloa Tower. It is associated with the Forth Naturalist and Historian of Stirling University in publishing and with the annual 'Man and the Landscape" symposium (conference).

Research projects have included - Linn Mill site, mining and Alloa Harbour (these have been pubished as booklets Linn Mill, Mines and Minerals of the Ochils and Alloa Port, Ships and Shipbuilding, Old Alloa Kirkyard, Archaeological Survey 1996-2000:  funded by Local Heritage Initiative Scotland. Other publications include David Allan; The Ochil Hills - landscape, wildlife, heritage, walks; Alloa Tower and the Erskines of Mar; and a twice yearly Newsletter. Aprill 2011 was no 86 and there are 5 yearly contents / indices. The printed newsletter is no longer published. Most recently we sponsored various new publications such as the book Bonanzas and Jacobites, Alloa East and West Walks guide, Memento Mori - guide book to Alloa Kirkgate Churchyard, also Back on Track, and our latest publication, The Craigrie and Cartmorn Lades. In conjunction with the Inner Forth Landscape Initiative, several research projects have been undertaken investigating the Two Estates, Alloa and Clackmannan.

Membership is open to anyone with an interest in, or desire to support the aims of the Society in this field of Local Studies.
