THECA News is a quarterly newsletter which has been published since 1999. Articles include reports of THECA’s series of monthly talks, reports of THECA excursions and activities and articles written by members which relate to environmental issues.   Articles focus primarily on local and regional issues but may also explore wider environmental issues and concerns. THECA members are encouraged to contribute stories and photos. THECA membership includes four issues of THECA News annually while local libraries and other similar organisations also receive complimentary copies.
