Town seeks frog-calling volunteers BRENNA MOORE Special to The IFP Looking to test out your frog-calling skills? Halton Hills Recreation and Parks Department is looking for volunteers who are interested in learning how to identify frog calls and to use that skill to protect the environment here in Georgetown. Under the Town's Hungry Hollow Ravine Management Plan, volunteers are needed to participate in the first of a series of monitoring programs. Volunteers will be trained to identify different amphibian species and their calls and how to record that data in the Hungry Hollow Ravine Frog Count workshop by Don Scallen of the Halton/North Peel Naturalists Club and Heather Lynn of Credit Valley Conservation. The workshop will be held Monday, April 10, 7-9 p.m. at the Civic Centre. "This is a good family activity as many families use Hungry Hollow," said Town Manager of Parks Warren Harris, chair and project manager, adding it's a good volunteer opportunity as "it's a way to ensure further public use of Hungry Hollow." Volunteers in the program will learn how to judge different frog calls, the frequency of the calls, and whether there are choirs of frogs in the ravine. All of this information helps to determine both the population of frogs and health of the Hungry Hollow ravine. "The size and population of the frogs helps to determine the quality of the environment in the ravine," Harris said. "By having results done yearly, we can see if there has been any significant changes."
