February Program

“Wildlife, Landscapes, & Geology”
Dr. Dale Leckie

Online Only!
7:30 PM Thursday February 20, 2025

Explore Grasslands National Park, the Great Sandhills Ecological Reserve, the Missouri Coteau, and the Saskatchewan River valley with Dale to observe how the geology of Saskatchewan controls where wildlife lives. Dr. Leckie will talk about his new book “Wildlife, Landscapes, & Geology”.

From the vast rain shadow of the prairies to the Rocky Mountains, from deeply entrenched rivers and their prairie oases, and glaciated terrain, geology has a strong impact on wildlife. The relationship between wildlife and landscape is explored and exemplified in the lives of burrowing owls on glaciated plains, and greater short-horned lizards surviving in semi-arid badlands, of golden eagles and the Rocky Mountains, the American pika and eroding mountains.

In the prairies, pronghorn antelope require semi-arid, flat to gently rolling glacial terrain and expansive mixed grassland for survival. This setting allows antelope to use their long-range vision to escape predators using intense bursts of speed. The vegetation on which antelope feed is controlled by aridity in the vast rain shadow of the Rocky Mountains. South-facing slopes of entrenched eroding river valleys, glacial meltwater channels, and badlands coulees provide favourable habitat and warmth for the greater short-horned lizard, prairie rattlesnakes, eastern yellow-bellied racers, and bullsnakes.

After the glaciers melted, large lakes formed across the prairies which then drained. Strong winds constructed extensive fields of sand dunes of which Ord’s kangaroo rat take full advantage.

During the last glaciation the kilometres-thick Laurentide Ice Sheet depressed the Earth’s crust across the prairies. When the ice melted, the heavy load was reduced causing the prairies to uplift and river valleys to become deeply entrenched. Today, meandering rivers in valley bottoms allow for the growth of towering cottonwood forests, which are oases providing specialized refuge from sun and heat for birds, reptiles, and mammals.

Dale Leckie, Ph.D., P. Geol., is a geologist who worked at the Geological Survey of Canada and as chief geologist at Nexen, a large Canadian energy company. He has edited numerous books and published widely on the geology of western Canada. He is adjunct professor in Earth, Energy, and Environment at University of Calgary. Dale is recognized for his long-term contributions to geology and is an honorary member of Society for Sedimentary Geology (SEPM) and Canadian Energy Geoscience Association. Dale’s most recent book “Wildlife, Landscapes, and Geology – An Alberta and Saskatchewan Touring Guide” is third of his best-selling trilogy. Most recently, Dale is the recipient of the 2024 AAPG Geoscience in the Media Award in recognition of his books.

Monthly Meetings and Speaker Programme

Listen, learn, and share ideas with people who are passionate about our natural world! 

SNS offers a monthly speaker programme from September to April on the third Thursday of the month. All meetings are live streamed through Zoom.

During the fall and spring months presentations will be in hybrid format: speakers will present live at in-person meetings while being simultaneously streamed through Zoom. During winter months speakers may be streamed from outside the Saskatoon region and on these occasions, there will be no in-person meeting.

All are welcome to attend these meetings either in-person or through Zoom. Look for details about each month’s meeting in the SNS membership newsletter, confirming any in-person meeting time and place. A reminder email with the meeting details and Zoom link will be sent to each member whose current email address is on file.

Non-members who wish to attend through Zoom should provide their name and email address to Claire Bullaro at c.bear@sasktel.netfor each meeting. Please consider becoming a member of the Saskatoon Nature Society if you wish to receive the Zoom link automatically each month.

In person meetings are held on the University of Saskatchewan Campus and are thus subject to the university’s rules regarding COVID restrictions. At present, masks and social distancing are encouraged but not required. We will not be providing shared refreshments, so please bring your own drinks and snacks.

The monthly meetings include announcements from the SNS president. If you have an announcement or notice, please contact the president at least 2 days before the meeting.
