Blackie Spit Park: Wildlife Habitat Enhancement Plan - City of Surrey

3.2 Ongoing Maintenance Requirements
Every three years monitor the height of vegetation on the central dykes and Cannery Spit. Either
remove species that germinate, such as alder, or top tall-growing trees at a maximum height of 5 m.
Low-growing plants, such as Pacific crabapple that may occasionally exceed 5 m, can be left.
3.3 Initial Enhancement Costs
• Staff time may be required to consult with local naturalists about the desirability and feasibility of
providing nesting structures on pilings within the park and for assessing nesting structure needs
for pilings outside the park. A volunteer group should provide structure designs and a materials
cost estimate.
• Capital costs may be incurred for providing materials to a volunteer group to build and install
nesting structures. For this item, a fixed budget can be established that will determine the number
of structures that can be constructed. There is no required budget for this management activity,
but a suggested amount is $200.
3.4 Monitoring Schedule
• Monitor tree growth once per year, ideally at the end of the growing season, and take any
necessary action.
• Consult with naturalists annually to determine whether any capital costs need to be incurred to
maintain nesting structures.
