2011 Tin Can Bay Annual ShoreView Artshow

9 June 2011 – evening 6-9pm

Biggest and Best, and More

The art show was the biggest and best yet. We are on track for this to be an annual highlight event for environmental awareness in the region.

The artworks and photographic displays once again highlighted the beauty of often-maligned mangroves and tidal wetland areas. These works show just how important these natural areas are to the local community and aesthetic value of Tin Can Bay.

The gauntlet was laid down at this years gathering to find the world’s biggest mangrove tree. Dr Norm Duke said, it would be hard to find tall individuals locally, but it seems we are right up there with large stem diameters. The Grey Mangrove (Avicennia marina) trees on Lindsay Titmarsh’s place (Tandora) at the mouth of the Mary River, have possibly the largest stem diameters of any mangrove tree. Lindsay has measured his trees at around 3 metres in diameter. They don’t look much – these old guys – they are dead in the middle and they have scraggy tops, but they are really, really old - as determined by carbon dating to be around 730 years of age.

The art show was also an opportunity to provide feedback on some of the key findings of community collected data from MangroveWatch surveys. This was the first time that a direct inter-annual comparison of mangrove condition has been possible. Preliminary data from Snapper Creek shows that this estuary has had a rapid recovery from the drought, with notable increase in mangrove canopy between 2009 and 2011. Of note was the increase of in-stream fish habitat (logs) brought down by the recent freshwater flush. The data indicates that Snapper Creek is in good health with a high resilience capacity. Long-term data on habitat change since 1977 presents a somewhat different picture however, with large areas saltmarsh and saltpan replaced with mangroves owing to increased nutrient availability from the STP and nearby township. These changes highlight how sensitive sand based ecosystems are to nutrient addition. For more information see the presentation results in full in the “Latest News” section on the website.

Community Volunteers

A key feature of MangroveWatch is its close partnership between community volunteers and scientists from the James Cook University’s Mangrove Hub. Together they are systematically recording basic data as video and still imagery for assessments of estuarine habitat health.

Armed with expert support, training and advice, MangroveWatch volunteers in key regions are actively contributing to the monitoring of local estuaries and shorelines. An important goal in this phase of the program is to develop a network of like minded groups with the aim of producing public documents that describe important issues affecting local estuaries and mangroves, and their overall health.
