Nicole Marcotte

nmarcotte@forterra.org | 206-905-6924

Stewardship Associate, Forterra

Nicole comes to us from the Northeast, where she graduated with a degree in Environmental Studies from St. Michael’s College in Vermont. She made the jump to Seattle to serve as a 2014 AmeriCorps member with EarthCorps. After a year of grubbing immense amounts of blackberry, spraying knotweed along the Cedar River, maintaining trails in the Alpine Lakes Wilderness and planting plenty of native species, she realized that her true passions lie in habitat conservation and restoration. This newfound passion led her Forterra, where she helps with Green Seattle community engagement. If she’s not out frolicking through alpine meadows in her free time, you can find her in Washington Park Arboretum where she likes to create botanical-artwork from fallen flowers and foliage.
