Arbor Month

April is Arbor Month!

Arbor Day is America’s National Tree Holiday, observed on the last Friday of April to celebrate the role of trees in our lives and to promote tree planting and care. Here in Lake Oswego, we celebrate the entire month of April as Lake Oswego Arbor Month. Click here to read the City’s proclamation.

For 34 years, the City of Lake Oswego has earned Tree City USA (TCUSA) recognition from the National Arbor Day Foundation for demonstrating a strong 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 $2 per capita on urban forest management, and proclaiming and celebrating Arbor Day annually.

This year, the Arbor Day Foundation also presented Lake Oswego with a Tree City USA Growth Award, which recognizes innovative projects and higher levels of tree care by participating Tree City USA communities. The Growth Award was awarded to Lake Oswego for developing the 2022 State of the Urban Forest Report, an in-depth analysis of the City’s tree canopy.
