More Habitats, Even More Plants:
Microhabitats & Diversity in the Garden
This talk will look at how designing a garden for plants differs from plants as objects to design with. The emphasis will be on physical site conditions and microhabitat creation, especially using rock garden techniques. Tony will look at microclimates around the house, and microhabitats designed with rock and soil, especially sand beds, crevice gardens, plus using tufa and troughs plus other containers (even in-ground “containers”) to maximize the plant diversity you can grow.

Candace Dressler : Native Plants in the Garden
Candace Dressler, will discuss how different plants are native to different parts of the planet and will give examples of the different biomes on the planet and the ecoregions and districts in North America. She will present how to use plant nomenclature and plant tags to help determine if a plant is native to the Ottawa area. Fran Dennett will give an overview of some of her favourite native plants that she says have brought more birds to her backyard gardens and reduced garden maintenance requirements.This will be a zoom meeting.

Plant-Substrate-Climate Relationships: Changing Rules In A Changing World
Climate is an important factor influencing plant diversity and distributions, but, climate is not the only important factor. Within a climatic area, substrate geology is also an extremely important factor that influences plant diversity. As a geologist, I am fascinated by plant-substrate relationships. My presentation will touch on several distinctive plant-substrate-climate relationships that illustrate the influence of geology and climate on plant diversity. I will also speculate on the impact of a changing climate on plant diversity in some areas. The presentation will touch on several geographic areas, including: a) limestone barrens along the west coast of the island of Newfoundland; b) limestone alvar pavement of Manitoulin Island, Ontario; c) alpine plants on the ice-free landscape in front of the Athabasca glacier, Alberta; and d) halophytic plants of the Takhini Salt Flats, Yukon.
