Each year, the City of Lake Oswego Parks & Recreation Department teams up with the Planning Department to celebrate Arbor Month! Did you know the City of Lake Oswego is celebrating its 35th year as a Tree City? This prestigious award demonstrates a solid commitment to managing and caring for trees. Cities earn TCUSA status by meeting four standards: maintaining a tree board (the Parks, Recreation and Natural Resources Advisory Board), having a tree ordinance, spending a minimum of $2 per capita on urban forest management, and proclaiming and celebrating Arbor Day annually.

Join us this month in exploring the "TREE OF THE WEEK." We will highlight remarkable local tree species that add beauty, diversity, and significance to our community. Join us on this journey of exploration and appreciation for the wonders of nature! Stay tuned for some snazzy social media reels with our very own Park Rangers and Staff walking us through the remarkable trees around our neighbors.
