520 Bridge Update
Arboretum Supports Grassroots Call for Ramp Memorial 
The "ramps to nowhere" in the Arboretum - remnants of the never-completed R.H. Thomson Expressway - are scheduled to be removed by WSDOT as part of the construction of the new 520 bridge. At a meeting yesterday, the Arboretum and Botanical Garden Committee voted to support a grassroots request to preserve some pieces of the ramps and use them to create a memorial to the citizen activism in the late 1960s and early 1970s that halted the construction of the planned expressway through the Arboretum. Read Knute Berger's article in Crosscut celebrating the Arboretum's decision.

Baggy Branches
Arboretum Hemlocks Focus of Research Experiment  
If you've recently visited the Arboretum, you've probably noticed some white mesh bags covering the branches of our hemlock trees. What gives? The bags are part of a collaborative research project between UW Botanic Gardens and the University of Massachusetts, Dartmouth. Researchers are trying to determine why the hemlock woolly adelgid - an insect causing major damage to hemlock forests in the eastern U.S. - is a relatively benign herbivore on the West Coast. It may be because western hemlock species are more resistant to the bug, or perhaps because the bug has more natural enemies on the West Coast keeping its populations in check. The bags in the Arboretum are designed to keep out predators of the adelgid, so that the researchers can figure out what's happening here and hopefully apply the results to the management of pest populations in the East.
