The public is invited to two free training workshops for prospective volunteer monitors of local frog populations. Staff from Shirley Heinze Land Trust, The Field Museum, and Indiana University Northwest will present the workshops on Thursday, February 15th, and on Tuesday, February 20th from 7-9pm at the Meadowbrook Conservation Center in Valparaiso. The two sessions are identical in content. The abundance and distribution of frogs over time is an important indicator of the health of aquatic ecosystems, as frogs are very sensitive to changes in their environment. New participants who would like to become a monitor will be assigned a preserve or natural area close to their home. Persons wishing only to learn about the program are also welcome. Spencer Cortwright, Biology Professor at Indiana University Northwest, will lead the Thursday, February 15th workshop, and Alan Resetar, Amphibian and Reptile Collections Manager at The Field Museum, will lead the Tuesday, February 20th workshop. The Meadowbrook Conservation Center is located at 109 W. 700 N., Valparaiso, IN 46385.
