Tree Guard
Ian Vierck and DBB
Tree Guard No. 01 is a provocative pop-dipped reinterpretation of the urban steel tree guard. The modular prototype is inspired by timber-framed barn-building and high-visibility destruction/construction barriers. This dramatic tree guard is intended to capture human attention, land stewards’ imagination, and the value of the potential tree within it. This prototype is being further developed as a series of public landscape installations on contested land under threat of development in Eugene, OR. The Tree Guard No. 01 was created in the spirit of Jack K. Byers’ mantra, “Protect to Study; Study to Protect.”
Full-scale prototype of modular landscape installation element, nominal 4” x 6” timbers, structural screws, primer, acrylic paint, aspirin, and band aids, 7’ x 14’ x 18’, 2022. Collaborators: David Buckley Borden, Nancy Silvers, and Ian Vierck.
