The first phase of the trail and habitat improvements in Lynnmouth Park focused on re-establishing streamside habitat with native trees and shrub plantings along the west bank of Lynn Creek. Lynn Creek is an important salmon bearing stream and the newly planted vegetation helps support local fish and wildlife populations.

A number of community stewardship events were held to remove invasive species such as Japanese Knotweed and Himalayan Blackberry which made way for the installation of hundreds new native plants.

To help establish the new vegetation and protect the environmentally sensitive creek side area, fencing was added which includes three formal access points to the creek.
