Christchurch City Council Nursery Seed Collection and Processing

摘要

The Christchurch City Council (CCC) nursery collects seed tor its revegetation projects from the various reserves that the city administers. The main collection sites are the Avon - Heathcote estuary, Travis Wetland, Brooklands Lagoon, and the Port Hills.We try to collect from wild, natural stands in preference to cultivated plants. This is a deliberate attempt to try to increase the population of known local origin plants.We avoid collecting from parks and gardens within the suburbs as few of the established native plants in suburban parks are known to be of local origin. It is also difficult to identify any local origin plants that may be present. Any that are present are also readily able to cross with the same species of unknown origin in the park or in nearby gardens. Pittosporum, Cordyline, Phormium, and anything with separate male and female plants must outcross with another individual to produce seed.
