Trees on the Move: Can Maples and Buckeyes Migrate?

Activity A: What do climate models predict about tree ranges?
This lesson introduces examples of how General Circulation Models [GCMs] predict possible scenarios of climate change. Three methods of visualizing change are introduced and students compare how sugar maples and buckeye trees’ climate niches are likely to be altered.

Activity B: How can trees migrate?
The seeds of maples and buckeyes are “dispersed” in an outdoor simulation of how far a tree species might be able to spread over several tree generations.

Activity C: How does temperature affect maple seed germination?
Students examine research data on seed germination at different temperatures to infer some of the impacts of temperature on species survival.

Activity D: After the maples, then what?
Students study an outdoor area that has sugar maples and other species. Following research methods of Catherine Keever, they catalog the size and relative abundance of species in the plot and infer what species is likely to succeed if maples disappear.
