Underwater Worlds of the Bruce
To hear the audio recording of this meeting click here.  Chairperson Megan Miles welcomed members and guests and reported on BPEG’s ongoing activities. Two upcoming workshops: Sustainable Tourism Discussion at the Tobermory Community Centre Feb. 7, 7 P.M. and Coastal Community Workshop at the Sauble Community Centre, Feb 28, 7 P.M. Jim Kuellmer asked for comments on the new community curbside waste and recycling program and for volunteers to assist in the distribution of blue boxes for that program. The speaker for the meeting was life-long Peninsula resident and long-time BPEG member Jenna McGuire. Jenna is Interpretation Coordinator at the National Parks in Tobermory and spent a year recently at California State University completing a graduate program in scientific illustration. Her presentation was to illustrate the ‘Underwater Worlds’ of aquatic life on the Bruce Peninsula. Jenna also works independently in illustration and graphic design. Jenna has been studying marine life on the Peninsula for several years and provided us with a most informative program of tales of a wide variety of aquatic environments and species. The Peninsula is well known for its vast diversity of life forms. The aquatic environment is perhaps equally diverse but less well understood. From the deep Great Lake basins to the coastal wetlands to the inland lakes, wetlands and fens to the tiny vernal pools to even the mosses on rocks and trees, there are hundreds of aquatic, or mostly aquatic, species that comprise our treasured Peninsula. Jenna explained how fish sense tiny waves of motion and sound in their water surroundings with their ‘lateral lines’ and bone structures sensing sound, how some molluscs have evolved special lure like appendages to attract fish near so they can implant their eggs in the fishes’ gills and scales. She cited several other fascinating tales of special adaptations and symbiotic relationships between species to assure survival of invertebrates, plants, insects, birds, amphibians and mammals. Jenna was careful to point out that despite all the established knowledge there are still many species to discover and much to learn about the aquatic environments of the Peninsula. Join us Wednesday, March 01 at 7:30p at the Lion’s Head Rotary Hall. The talk will presented by Sources of Knowledge. The event is designed to reflect on key milestones over the past 140+ years, and how they have had an effect on the Bruce Peninsula of today. What can we learn from the past, so we can envision a more sustainable future?
