What we do

THECA is involved in a wide range of environmental and community activities, from regular drop-in morning teas, to bushcare and other conservation activities. THECA could not exist without the contribution of many volunteers as well as the committee members. They are involved in, for example, bushcare, children’s activities, workshops and field trips, special projects, birdwalks.

See our Events Diary for times and dates of meetings, activities and working bees. For more information on any of our activities, please contact us.

Brisbane's Wild West Calendar

2016 ad cid C16CFE2D 029B 47A6 B95A 563FE1ED3649

Every year THECA, with support from local environmental groups Moggill Creek Catchment Group (MCCG) and the Rural Environment Planning Association (REPA), publishes a calendar that displays photographs by local photgraphers, of native fauna and flora of the western suburbs of Brisbane. Around May each year, we call for photographic submissions for Brisbane’s Wild West Calendar. Anyone is welcome to send in submissions for consideration.


Bushcare is a core activity for THECA and we actively support several groups working in Mt Coot-tha Forest. Volunteers are a key part of these programs and all volunteers are welcome! Please contact THECA office for any questions.

All these bushcare activities are supported by Brisbane City Council’s Habitat Brisbane program.

Children's and Family Activities

Activities are based at The Hut, generally during school holidays. They are led by experienced teachers, and include both indoor and outdoor hands-on activities.

Spotlighting walks for families are also held from time to time, starting at The Hut and at other natural areas in the western suburbs.

Special Projects

THECA has been involved in a number of special projects over the years. In 2015, three workshops for those involved in the land management field are planned to focus on the significance, management and conservation of scarred trees and very old (veteran) trees which have wide-ranging cultural and ecological significance.

See list of past special projects.


Family nightwalks are held regularly throughout the year at various locations to view our urban and bushland night creatures in a relaxed manner.

On the November 2014 Nightwalk at Gold Creek several possums, two snakes and a range of birds were seen as well as insects and spiders.

At our February 2015 walk, we saw lots of possums near The Hut. THECA member Vanessa Gorecki showed us how to identify microbats using a mobile phone app that converts their high frequency calls into visual recordings. Thank you to Vanessa and to our regular leaders Justin Watson, AndrewTaylor and Dawn Muir.   

See our Nightwalks sightings list.

Field Trips

THECA regularly runs field trips to locations in south-eastern Qld. Recently, we travelled to North Stradbroke Island to discuss Aboriginal issues related to natural resource management and visited Dr Robert Raven at the Qld Museum to learn more about spiders and Leonie Coghill to find out about repatriation of Aboriginal aretfacts and remains.
