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

3.4 Monitoring Schedule
• Monitor the success of wildflower growth. Most wildflowers are annuals (lupin and most lilies
are perennial) that grow best on disturbed sites, so periodic disturbance, such as scarifying,
every 2 to 4 years, may be required. Also add new seed, as required.
• If the wildflowers do poorly because grasses are too aggressive, try shallow rototilling and
planting low-growing grasses, such as Chewing’s fescue and creeping red fescue.
• Monitor aquatic plant growth annually until established, then every 5 years. If extent of growth
becomes a problem, impeding water flow in the south ditch, or obscuring open water in the
north ditch, remove some areas of plants, as required.
