conservation approaches

Protected areas as “islands” surrounded by unsuitable habitat

Example: Olympic National Park How have ideas about

islands informed the design of protected areas and conservation reserves?

Application of island biogeography to reserve design SLOSS debate: Single Large Or Several Small

Can ideas about island biodiversity be applied to terrestrial areas?

Edge effects

Patch size

Protected areas and the need for corridors and “connectivity conservation”: Yellowstone to Yukon Conservation Initiative

Keechelus Wildlife Overcrossing on I-90: Washington’s first-ever wildlife bridge over a highway, and the largest wildlife overcrossing in North America

• In situ vs. ex situ conservation

• Species-based vs. habitat-based

• Protected areas

• Assisted migration

• Rewilding

• De-extinction

conservation approaches

Assisted migration as climate-smart conservation?

• In situ vs. ex situ conservation

• Species-based vs. habitat-based

• Protected areas

• Assisted migration

• Rewilding

• De-extinction

conservation approaches

Oostvaardersplassen, a rewilding project in the Netherlands

• Rewilding: large-scale conservation aimed at reintroducing the megafauna that humans have wiped out as we spread across the globe.

• In situ vs. ex situ conservation

• Species-based vs. habitat-based

• Protected areas

• Assisted migration

• Rewilding

• De-extinction

conservation approaches

De-extinction: Using biotechnology to bring extinct animals and plants back to life

• Methods: back breeding, cloning, and synthesis (reverse engineering) • Video: The science behind de-extinction

Arguments for de-extinction: • The science may benefit living species • Can allow humans to “undo” negative impacts • May increase hope about the state of biodiversity

Arguments against de-extinction: • Misallocates resources away from preventing

extinctions • Perpetuates myth that humans can undo harm • Ecosystems have fundamentally changed since many

species went extinct
