The CFNC was founded in 1976, after local historian Raymond Bradfield called a public meeting in February of that year to garner interest. Bradfield's proposal was well supported and he was elected the club's first president. By 1977 the club had developed close working relationships with other field naturalist groups in the state, inviting Jack Wheeler, then president of the
Geelong Field Naturalists Club, to their club meeting for a presentation and excursion to the Kaweka Nature Reserve in Castlemaine. On 21 November 1985, a white box tree
(Eucalyptus albens) was planted in the southern portion of Castlemaine's Kaweka Reserve, near Hall Street by Bradfield, to commemorate both the 10th anniversary of the Castlemaine Field Naturalist Club and the 25th anniversary of the Western Victoria Field Naturalists Clubs Association. In 1982, Bradfield was awarded the Medal of the
Order of Australia for his services to the Castlemaine Community. Ern Perkins, a founding member of the CFNC, was awarded an
Order of Australia Medal in 2000 for his conservation and natural history work as a part of the CFNC in the Castlemaine region. In 2008, Perkins also received the
Australian Natural History Medallion for his work in the research and recording of the native flora and fauna of Victoria. Perkins led many of the CNFC's conservation efforts in the region, including co-authoring
Eucalypts of the Mount Alexander Region (2016) and managed the club's Photopoint Monitoring Project, personally taking photos of key conservation sites over the course of 40 years. Over his 50 years of support for the club, Perkins undertook decades-long population surveys of numerous local fauna, including studying
swift parrots (
Lathamus discolour) and
regent honeyeaters (
Xanthamyza phrygia) for the
New Atlas of Australian Birds. Perkins also coordinated conservation projects for the Diggings National Heritage Park, Castlemaine Botanic Gardens and
City of Castlemaine. Perkins' sister, Pat Joan Murphy, was a key member of the
Field Naturalists' Club of Ballarat and renowned contributor to the
National Herbarium of Victoria, donating 1138 specimens. The two undertook field trips together and facilitated joint excursions between their respective clubs, during which many of Murphy's key specimens were found. Before his death in 2016, Perkins held much of Murphy's private collection that was not donated to the National Herbarium, including specimens of the rare
Thelymitra flexuosa orchid, which Murphy had found in the Ballarat area. == Publications ==
