Did you know that the Washington Park Arboretum often serves as a research site for researchers at the School of Environmental and Forest Sciences? Recently, researchers at UW have been using the Arboretum to study LiDAR and its applications. LiDAR (Light Detection and Ranging) is a method of airborne laser scanning that can be used as a tool to inventory and manage forests. Below are some of the research papers discussing their findings.

New Issue of the Rare Plant Press

May 17th, 2012 by Heidi Unruh, UWBG Communications Volunteer

The latest issue of the Rare Plant Press is out.  Learn about the rare Astragalus plant, projects to conduct a population  estimate of the largest Sidalcea oregana var. calva and mapping Sisyrinchium sarmentosum populations, and more! The Rare Plant Press is a publication of Rare Care, a program dedicated to conserving Washington’s native rare plants.

Update on the Music of Trees project

April 24th, 2012 by Heidi Unruh, UWBG Communications Volunteer

Last winter we told you about Abby Aresty, a Seattle-based composer,  sound artist and UW doctoral student in music, who was raising money for a sound installation in the Washington Park Arboretum. She has since met her fundraising goal, and is hard at work recording sounds in the arbortetum. “Through detailed analysis and sonic manipulation, these simultaneous yet distinct layers of sound will be brought into dialogue with one another. The music will then be brought back to the original sites and played back softly through small speakers attached to the trees.” The installation is scheudled to run for 6-8 weeks this fall, and will be free to the public. Visit the project website to learn more, and follow Abby’s progress on her blog.

Did you know that the Camas bulb with its stunning blue and purple star-shaped flowers is native to the western US?

We recently spotted some Camas in bloom in the Union Bay Natural Area near parking lot E5. Go have a look!

Come join us for a week of spring time explorations, investigations and adventures. We will become nature detectives looking for signs of spring. What are the birds telling us? What are the plants doing? Where are the animals hanging out? We will look for clues while playing games, doing spring-themed crafts, reading and telling stories, and adventuring through the Arboretum. The camp runs April 16-20, 9am-3pm (before and after care available if 6 or more campers sign up). The cost is $225 ($200 for Arboretum Foundation members). Visit the Spring Break Camp page for more information or call (206) 221-6427.
