Urban tree news: Pittsburgh’s master plan, San Francisco street trees on their own, and the eucalopalypse

There’s some big news about urban forestry coming out of Pittsburgh and San Francisco over the past two weeks.

• An organization called Tree Pittsburgh is at work on that city’s first ever Urban Forest Master Plan, and is now soliciting public input. Since a majority of the city’s trees are privately owned, public buy-in will critical.
• As of last week, San Francisco’s Department of Public Works is no longer responsible for the city’s 23,000 street trees. Their maintenance and upkeep costs are now up to local residents.
• And also in San Francisco, the long-simmering battle over the fate of the thousands of non-native, invasive eucalyptus trees is heating up. What’s a tree-hugger to do when entire regions become taken over by trees with low value for native wildlife species?

Thanks, by the way, to Georgia Silvera Seamans at the local ecologist blog for sending these (and many other recent links) my way.
