Wooded trails provide access to the Oyster River and several swimming holes. Located within an active flood plain causes changes to trails and access to the river.
Bracken Park is located within an active floodplain along the Oyster River. Flooding is most evident along the park’s northern portion, where a network of watercourses has scoured the forest soils. The forested areas 
of Bracken Park are dominated by Douglas fir and sword fern where soil has accumulated and is most stable. In areas of flooding and soil movement, red alder, salmon berry and skunk cabbage dominate. The water-loving black cottonwood enjoys riverbank and watercourse locations.
