This week, we're Growing Deeper into a topic introduced in an episode of our Plant Talk webinar series (watch here). Keystone species, an idea discussed by entomologist Doug Tallamy in several of his books, are a foundation of healthy, functioning habitat. Today we're discussing some of the keystone species of the Great Plains and how understanding this theory impacts the way we design urban greenspaces.
Top 9 Keystone Genera (look for species native to your area):
- Quercus (Oak)
- Salix (Willow)
- Prunus (Cherry, Plum)
- Betula (Birch)
- Populus (Cottonwood)
- Ulmus (Elm)
- Solidago (Goldenrod)
- Helianthus (Perennial Sunflower)
- Symphyotrichum (Aster)
