Pacific Madrone Research


Welcome to the WSU madrone research website. Here you will find information on

What's new

Common garden plantings have been established in each of California, Oregon, and Washington states, with a site planned for Vancouver Island, BC, in 2013. Read more about the project here. First year measurements are being taken this fall/winter.

Photos from 1st year measurements at Starker Forest.

The Sprague site has been measured.

A serious foliar blight affected Pacific madrone in 2011. Read about it here. We would like more information about how these trees are doing one year later in 2012 . As before, send your descriptions and photos. For more information, click here.

We are setting up a mailing list to keep people informed about this project. If you would like to be on it, email Marianne.
