Year 12 Biology Ecology Field Trip

A brief biological report from the scenic Warrington mudflats

On a picture-perfect early autumn day the Level 2 Biology students ventured to Warrington to collect data for their internally assessed task investigating interrelationships in a mudflat community. IB Biology students looked for ecological associations by collecting data for a “Chi-Squared” statistical test. This is a field trip that has been a regular occurrence over many years. Some trends remain constant, such as the large number of cockles at the low water mark. These cockles typically give way to wedge shells and then bamboo worms. Unusually there were a very low number of wedge shells and no sea lettuce was apparent. We hypothesised that the reason for this was the very low number of strong southwest wind events experienced over summer. Photo credits: Craig Knights.
