Virtual Forest Bathing Walk

Join UW Botanic Gardens and Cascadia Forest Therapy for a unique virtual forest bathing opportunity. Forest bathing (or shinrin-yoku) has been popular in Japan for decades and is gaining momentum in the US. The practice encourages you to walk in the forest (or the space available to you) at a slower pace and take in the atmosphere around you. Multiple scientific studies have shown that it lowers stress and blood pressure levels, while increasing immune system functioning, making you more resilient to diseases and illness. These walks are slow-paced and can take place in any space. All participants will be joining the call from their individual space (whether in nature or home) where they can practice safe social distancing. If going outdoors, we encourage you to stay close to home and follow social distancing guidelines. During the walk the guide, in partnership with the forest, will offer an evolving series of invitations crafted to help participants slow down and open their senses.

CANCELED - Friends of Seattle's Olmsted Parks Tour of University of Washington Campus

Relocated from downtown northward to larger, less-developed acreage in 1895, the University of Washington consisted of just six buildings when the Olmsted Brothers firm prepared a general campus plan in 1903. John Charles Olmsted returned in 1906 to design the grounds for the 1909 Alaska-Yukon-Pacific Exposition (AYPE), which attracted over three million people to Seattle (population 240,000) that year. Olmsted incorporated the campus into the overall city park system and encouraged the university’s regents to reserve part of the campus for public park uses. Today it is an important element of the city’s open space infrastructure. Distance covered: Approximately 2.5 miles. Meet at the main entry to Gerberding Hall. This tour offered in partnership with Friends of Seattle's Olmsted Parks. Cost: $15 Register online or by phone (206-685-8033). Campus location: Gerberding Hall (GRB).

Forest Bathing Walk

Join UW Botanic Gardens and Cascadia Forest Therapy for a unique forest bathing opportunity in the Washington Park Arboretum. Forest bathing (or shinrin-yoku) has been popular in Japan for decades and is gaining momentum in the US. The practice encourages you to walk in the forest at a slower pace and take in the atmosphere around you. Multiple scientific studies have shown that it lowers stress and blood pressure levels, while increasing immune system functioning, making you more resilient to diseases and illness. These walks are slow-paced and generally cover less than a mile of trail. During this time the guide, in partnership with the forest, will offer an evolving series of invitations crafted to help participants slow down and open their senses. The opening of one’s senses encourages mindfulness, which readies the heart and mind to be fully present in the natural world. Come discover the medicine of being in the forest.

NEW DATE: Climate Change Impacts on PNW Trees Symposium

Rescheduled from April 15, 2020. Climate change introduces a new challenge for municipalities as it has the potential to affect areas of forest cover in ways we may not yet completely understand. The recent lack of cold winters, attributed to climate change, has allowed for the mountain pine beetle to wipe out enormous areas of forest land in Canada and the United States. Prolonged drought in California lead to thousands of acres of dead and dying trees in urban and rural areas. Dead and dying trees lead to increased chance of forest fires. Those who will benefit from attending this symposium include arborists in the municipal and private sectors, other professionals who work with trees and forests, as well as anyone interested in how climate change is impacting trees. Presenters will propose best practices for future tree selection, maintenance and management in light of climate changes. The goal for the symposium is to lay out a foundation of ideas and experiences, and use those to develop long ter… Contact Information: info@pnwisa.org.

NEW DATE: Basic Tree Identification

This workshop was originally scheduled for May 12 and has been postponed to September 2. Proper tree management starts with knowing the tree you’re managing. When trying to recommend an appropriate treatment, diagnosing an issue, or understanding how a tree will respond to a change in conditions, identifying the tree you’re dealing with is the first step. This basic identification workshop serves as an introduction to common terms, concepts, and techniques in tree identification.  The objective of the course is to get you familiar with how to identify a tree, covering leaves, fruit, bark, twigs, and form. As there are well more species that can grow in our region than can be covered in a single basic workshop, focus will be on larger concepts that will lay the ground work for future identification. We will cover the use of dichotomous keys and get familiar with descriptive terminology to help narrow down unknown species. The workshop will be inside for the first half and will go outside for the se… Campus room: Wisteria Hall. Presenter: Bess Bronstein. Contact Information: info@pnwisa.org.
