Two presentations at the end of March will provide opportunities to learm more about how we can make our urban landscape more bird friendly:

Can our urban rooftops provide habitat for wildlife? Much of our urban landscape is covered with structures and Portland is fast becoming a leader in promoting vegetated rooftops to capture stormwater. Is it possible to go even further and actually create functional wildlife habitat on buildings that will help birds, bats, bugs and other animals as they traverse our urban landscape?

 Could we restore nighthawks that once nested in gravel rooftops to our overhead skies by adding gravel to the roofs of riverside buildings on the Lower East Side? Could thousands of acres of grey industrial warehouse rooftops in the Columbia Corridor be converted to meadows for rapidly disappearing meadowlarks and streaked horned larks? Could the tops of our downtown skyscrapers provide a source for insect and a place to rest for migrating songbirds? What can we do on top of our own houses to support our the local wildlife?

 Join us and learn about how ecoroofs can make our urban landscape more sustainable for humans and wildlife.
