Alberta Park Nature Patch

A maple seedling sprouting surrounded by rocks, leaf litter, and other plant growth.

This installation of native species was the first in Portland Parks and a growing treasure for the community.

An important part of caring for these natural spaces as they grow is to keep the habitat free from encroaching invasive plants. The Alberta Park Nature Patch is beginning to see the results of seeds from nearby trees.

Bring yourself and a water bottle and help us remove these sprouts before they establish strong roots!

Portland Parks & Recreation Urban Forestry's mission is to manage and ensure Portland's urban forest infrastructure for current and future generations. Portland’s urban forest consists of 236,000 street trees, 1.2 million park trees, and innumerable private property trees.

Urban Forestry is involved in managing or regulating all of these trees to differing degrees. Urban Forestry staff issue permits for planting, pruning, and removal of all public and some private trees and are on call 24/7 to respond to tree emergencies.
