• Plant native trees along the west side of the unit as in Drawing 5:
• Black cottonwood 16
• Rowan 4
• Plant 4 cedar trees and 4 hemlock trees throughout the forested area and 2 Sitka spruce trees
in the south (Drawing 5).
Shrub/tree planting specifications
Plant at a 2 m spacing between plants. Plant in late fall. Newly planted shrubs and trees will need
watering for at least the first two summers, until established. If success is less than 80% after two
years, replace unsuccessful plants.
• Conduct amphibian survey.
• Place coarse woody debris for amphibian habitat (if required).
• Close all trails except one leading from the west parking lot through this area and connecting
to the multi use trail north of the west end of the south bay.
3.2 Ongoing Maintenance Requirements
• Annually or as required, remove all blackberry and broom from areas northwest of woodlot.
• Annually, cut areas with tansy in habitat units east of the multi purpose trail before the tansy
flowers. The timing and height of the cut will depend on the timing of plant growth and of the
bird nesting season; if cutting must occur during the nesting season, do not cut lower than 30
cm from the ground and remove cut material as it is cut.
• If tansy persists after several years of cutting, rototill (5-8 cm deep) the infested area and plant
with a grass/clover mixture such as the DF&WT set-aside mix, or one that will do well in the
soil conditions of the site.

• The monitoring frequency can be reduced for units where and when the rate of invasive species
growth decreases as a result of the control measures.
