  • Tribal Histories of the Willamette Valley with David G. Lewis March 5, 2024  6:00 pm - 8:00 pm Tryon Creek State Natural Area, Portland, OR, USA

    The Willamette Valley possesses a rich history as the ancestral lands of tribes like the Kalapuya, Chinook, Molalla, and others for millennia. However, much of this history has remained unrecorded, incomplete, or inaccurately portrayed. David G. Lewis addresses this gap in his new book "Tribal Histories of the Willamette Valley" by blending years of archival research and oral traditions and offers a nuanced perspective on the Willamette Valley's history and the experiences of Indigenous peoples in this region. By bringing these stories back into focus, readers gain a more comprehensive understanding of the colonization endured by the Native peoples of the Willamette Valley-- experiences often overlooked in many other accounts of Oregon's history.

    Join Oswego Lake Watershed Council and Friends of Tryon Creek for an evening with Oregon local Indigenous historian David G. Lewis. David will be giving a presentation on his new release "Tribal Histories of the Willamette Valley" and answering audience questions. He will also be signing books, which can be purchased at the event.

    Where: Tryon Creek Nature Center

    When: Tuesday, March 5th 6-8pm

    Free to the public! Books will be available to purchase and you can preorder here:

  • Monthly Work Party at Westlake Oak Woodland March 16, 2024  10:00 am - 12:00 pm 14903 Westlake Dr, Lake Oswego, OR 97035

    Join Oswego Lake Watershed Council and Westlake Homeowners Association for a morning of invasive species removal and land tending at Westlake Oak Woodland. This natural area is undergoing active habitat restoration and is home to centuries old oak trees, wetlands, and streamside habitat. These 20 acres of urban forest provide habitat for Slender Billed Nutchatch and other oak associated wildlife. We will be pulling invasive ivy, shiny geranium, and other invasive species. Certain plant species can outcompete and suppress native plant communities. By removing these weeds, we create more space for native plants to thrive. 

    These activities require volunteers to be able to bend over, kneel. Volunteers will be hiking and working off trail on uneven ground. We can arrange alternate projects for those with different abilities or mobility issues. We will be working outdoors so please dress for the weather (long pants and layers are recommended). Sturdy, closed-toed shoes are required. Bring your own water bottle and gloves if you have a pair. Hand tools, gloves, and training will be provided. Please bring any medication you may need (Asthma Inhaler, Epi-Pen, etc.) Please do not attend the event if you are sick. Children are welcome if accompanied by an attentive adult. Unfortunately, there is no bathroom on site. Please stop by, learn about the ecology of the local watershed, and lend a hand as we enhance this unique habitat! Registration is required! Questions?
