A New Dragonfly Sub Order with Bruce Archibald
A new dragonfly suborder, named Cephalozygoptera, was discovered in 2021 and consists of extinct fossil species from the Cretaceous and Cenozoic eras. This suborder was established by scientists after reviewing fossil records and discovering
distinct head shapes in these ancient insects, differentiating them from other groups within the order Odonata. The name “Cephalozygoptera” means “head damselfly” and highlights their unusual round heads and eyes compared to other damselflies.

Backyard Dinosaur Watching with Howard Richardson
This is in recognition of the fact that the birds we watch today are direct descendants of dinosaurs. It is an examination of the key fossils that link dinosaurs to birds, the people that made vital advances in our understanding and the modern techniques that have led us to this knowledge. The presentation will be illustrated with lots of good photos. Howard has retired from teaching at Okanagan College and Okanagan University College in order to pursue some serious birding and mountain biking.

Princeton will begin with a field trip on the afternoon of May 12 followed by the regular evening presentation.
Presentation: Restoring Native Grasslands in the Face of Invasives with Wendy Gardner

Restoring Native Grasslands in the Face of Invasives with Wendy Gardner
Grasslands are among our most threatened ecosystems, providing critical habitat, biodiversity, and ecological services. Yet their restoration is increasingly challenged by invasive plants that alter soil, competition, and recovery dynamics. This talk will highlight the importance of native grasslands, the difficulties posed by invasive species, and case studies of student research on grassland restoration.
Wendy Gardner is a Professor in the Natural Resource Science Program at Thompson Rivers University in Kamloops, BC, Canada where she has been teaching for over 20 years. Her research program is based around disturbance and plant community change with a focus on rangeland systems. Within her discipline she is an active member on the executive for several organizations (Society for Range Management, BC Technical and Research Committee on Reclamation, Grasslands Conservation Council of BC) and is passionate about educating people about rangeland ecosystems.
