EXTRACT: Frogs are known as an “indicator species” for water quality and local ecosystem health. With their permeable, membranous skin, through which respiratory gases and water can pass, and their shell-less eggs laid in water, they are sensitive to even low concentrations of pollutants in water and soils. In this study, frogs give a different kind of warning – as they begin calling earlier in the season, they reveal and give voice to the warming climate we now all inhabit.
The project is fortunate enough to be able to build upon weekly counts of calling frogs by ecologist Will Osborne during the 1980s and 1990s in the Canberra region. Effects of climate change can be incremental. They can also be non-linear, as scientist Pep Canadell explained to me in a recent interview. “Climate change expresses itself through extremes. It’s not a linear relationship of impacts,” he said.
This mixture of incremental change and unpredictable “expressions” can be difficult to record in the short term. With this in mind, the Frogwatch project builds on Osborne’s historical data along with the Frog Census data to chart changing trends. A preliminary comparison reveals that the breeding season of some local frog species might be commencing up to six weeks earlier than 40 years ago.
