Help our elms this Saturday
Have you seen the little signs around town on some of our American Elms?
You’ve probably heard of Dutch Elm Disease. It has killed millions of trees around the world and taught urban foresters a tough lesson: Don’t plant too much of one tree species.
Many of these American Elms remain alive in Portland. One big reason is a nonprofit called Save Our Elms. They raise funds to inoculate trees every three years at a cost of $125-$175 for each tree (using volunteer labor).
This Saturday, you can volunteer to help save these majestic trees. Approximately 90 trees will receive treatment this year.
Inoculation has had a significant positive impact on saving the majestic American Elms that grace the Ladd’s Addition neighborhood. Contact Toby Deming at [email protected] to volunteer, or simply show up at the event.

Tree news in links: What’s a dendrochronologist?
Who knows the difference between a dendroclimatologist and a dendrochronologist? Both forms of scientist will soon be studying the growth rings of Herbie, the 110-foot American Elm tree in New England that finally succumbed to Dutch elm disease a few weeks ago.
Of course, the scientists will be looking for clues to Herbie’s age and for answers about the climate, reports The Washington Post.
With thousands of Haitians fleeing the lingering chaos in their nation’s capital for rural settings, some are concerned the few remaining trees will be felled for fuel and sustenance.
“Given the earthquake’s devastation, there is now a mass exodus of people to rural areas, but these areas cannot even support the current population much less the hundreds of thousands of people migrating there,” said Ethan Budiansky, Africa and Caribbean programs officer for Trees for the Future, who regularly travels to Haiti to work on agroforestry initiatives.
“Land will become even more impoverished and the few remaining trees will be cut down unless strict measures are put into place,” Budiansky told the Environmental News Service.
The Microraptor lived 120 million years ago and was likely arboreal, further linking dinosaurs to birds, according to new research.
Scientists from America and China built a three-dimensional plastic replica to test the Microraptor’s hip rotations, making sure it could extend its hind legs for flight, reports MSNBC.com.
