Burke-Gilman Trail Vegetation Management Plan

Management Unit 7

Management Unit 7: NE 65th St. to NE 77th St.
The trail is bordered by single-family residences to the west and multiple-family residences to the east.

M7-E1

• Remove invasive species in middle section to improve native species development.
  
• Remove invasive species from MDi to the north.
  
• Diversify overstory using medium/small trees and plant native understory in MDi to the north.

Good native plant component being affected by invasive species. Introduction of tree species should be done with the consideration of view concerns in this section.

M7-W1

• Remove only Himalayan blackberry affecting tree performance.
  
• Remove all Japanese knotweed.

Blackberry in this area are easily accessible for picking by trail users. Japanese knotweed is strongly established and needs to be controlled.

M7

• Protect row planting trees from mower damage.

Signs of decline in tree health due to mower damage.

M7W2

• Reforestation needed due to severe pruning/topping of Bigleaf maples and occurrence of invasive species
  
• Plant low/medium height mixed trees and soil erosion control plants

Unprofessional pruning practices have led to severely damaged trees. Best approach is to start replanting using low/medium height plants to avoid future view problems.

M7E2

• Remove Hybrid black poplar, in direct competition with Douglas fir Performance potential of Douglas fir seriously affected.

M7W3

• Reforestation section due to badly pruned Bigleaf maple and invasive species in understory.
  
• Replant from mixed planting palette using small trees and mixed understory.

Unprofessional pruning. Requires replanting using small trees to avoid future view conflicts.
