Join the Arbutus ARME!

In 2019 we got together to jumpstart the Arbutus ARME. Where does the name come from? Arbutus menziesii, Pacific madrone, is the largest flowering tree of the family Ericaceae. A.R.M.E., like Army, is the shorthand abbreviation Arbutus menziesii. Like any other army, we are a force. More specifically, we are more of a botanical and community-powered collective of people focused on facilitating efforts at Pacific madrone research, conservation, restoration and education. We are an all-inclusive group, so feel free to call the tree by the variety of common names out there in the world. It can change based on your geographic location. Arbutus is the name often used north of the border in Canada. Madrone, madrona, madroño are all good too.

Washington State University Plant Pathology Program gathered partners and stakeholders together a few years back for the April 2016 Future of Madrone Symposium. Participant brainstorming spurred a wish list for research and networking. And some action, notably the creation of a survey and database dedicated to learning more about the condition of madrone. We are now submitting data via the TreeSnap mobile app to determine a more exact geographical range of the species while also pinpointing healthy and diseased trees from people’s mobile observations. You can help us collect data on the range and health condition of madrone!

Some near future projects include: another symposium dedicated to research and conservation, publishing a guide dedicated to the care and cultivation of the species. Let us know if you would like to be involved!
