Today's scavenger hunt focuses on urban trees and the theme of introduced species. Trees are living organisms yet they form habitat for other life forms. Together with frog, find the following specimens to upload on Thursday flex channel . One mark per photo!
1. Find evidence of an animal that lives on the tree. This could be a bug or a bird nest
2. Find a tree that has epicormic growth. These are called *suckers*. They are new shoots that grow out of the bark of a tree rather than from the tips of branches. They are sometimes a sign of a stressed tree
3. Next find a tree parasite *English Ivy*. This is an invasive species which climbs up trees and takes them down. When this unceded indigenous land was colonized, invasive plant species hitched a ride: 
4. Some of these introduced species were medicinal...Dandelion root is being investigated as a potent cancer treatment 
5. Finally, there is Sakura, gorgeous cherry blossoms brought over to Vancouver from Japan.
