THE FASCINATING BIOLOGY OF ORCHIDS
There are over 800 genera and 25,000 species in the Orchidaceae. Dr. Larry Peterson will discuss features of orchid biology that have led to rapid speciation in the family. Topics will include pollination mechanisms, associations with beneficial fungi, adaptations to a wide range of terrestrial habitats and the success of this group as epiphytes. The amazing diversity in floral forms has led to a multi-million dollar horticultural industry but has also resulted in many orchid species being poached from the wild. Because of this, and destruction of habitats, over 300 species are listed as endangered or threatened.
OSFN Indoor Meetings are normally held on the second Thursday of the month at 7:00 p.m. at the Bayshore Community Centre, 1900 3rd Ave E Owen Sound. There are no Indoor Meetings in July and August. Please see the individual event listings below for more details.
We invite speakers with a wide range of expertise from Grey/Bruce and other parts of the province. These evenings are open to the public. The auditorium is open by 6:30. The meeting gets under way at 7:00, and may include brief announcements by other organizations as well as OSFN club activities, club business, social time, nature sightings and reports.
The club also offers a full schedule of outdoor activities during the year. Through these outings, members learn more about the birds, plants, mammals and geology of this part of Ontario. We also keep a protective eye on our precious natural areas.
