Earth Day Community Work Party at Sehome Arboretum

Apr 22 , 9:00 am 12:00 pm

Join the more than 1 billion people worldwide who celebrate Earth Day by joining the City of Bellingham, WWU LEAD, Whatcom Million Trees Project, and Washington Trails Association for a volunteer work party. Together, we will restore habitat in the Sehome Arboretum by planting native trees, removing invasive species, spreading mulch, and more.

Event Details

When and where is the event? This event will take place on Saturday, April 22 from 9 a.m. to noon in and near the Sehome Arboretum. We will meet in the Western Washington University (WWU) parking lot located near the intersection of Billy Frank Jr. Street and East Ivy Street. Learn more below.

What will we be doing? We will remove invasive species such as English Ivy, Himalayan Blackberry, and Clematis in the area. Using the Miyawaki Method, we will plant a variety of native trees in an ecologically degraded area. Hannah Lewis – author of a book about the Miyawaki Method – will join for the work party and will give a brief talk after the event. She is also presenting about the Miyawaki Method at WWU on Thursday, April 20. The talk is free and open to the public.

Who can participate? All ages and abilities are welcome at this event. No previous volunteer experience is required. Please contact us at pkvolunteers@cob.org if you would like to request an accommodation or language interpretation.

What should I bring? We provide tools, gloves, snacks, and free coffee and pizza donated by Woods Coffee and Papa Johns. Please bring closed-toe shoes, weather-appropriate clothing, and a water bottle.

How do I sign up? Spots are limited. Please register for this event in advance.

The Miyawaki Method re-creates the conditions needed for a native forest to grow in decades, rather than centuries. This method is focused on planting forests rather than trees, the benefits of which include ecosystem function, carbon sequestration, habitat creation, temperature regulation, and low maintenance costs once established. As they mature, Miyawaki forests are ecologically functional and biodiverse. They are well suited to urban environments because they can grow in areas as small as six parking spots. They have been planted in former parking lots, medians, along highways, behind schools, and in other degraded sites around the world. Learn more about the Miyawaki Method during a presentation by Hannah Lewis at WWU on Thursday, April 20.
