Witty’s Lagoon Regional Park in Metchosin, Canada, comprises a number of different ecosystems and species, including several plant and bird species scheduled under Canada’s Species At Risk Act. One of these species is contorted-pod evening primrose (Camissonia contorta), which lives in the coastal sand ecosystem found on the sand spit. Unfortunately, the sand spit and many other areas of the park have been degraded by invasive plants and human activity. This project has two primary objectives: first, to identify and prioritize existing values and threats within the park boundaries, and second, to create a restoration plan for the sand spit. These objectives were achieved by following the Conservation Standards set out by the Conservation Measures Partnership (CMP). Ten conservation targets were chosen for the park. Field surveys were conducted to measure various indicators of health for each target. Miradi, CMP’s conservation software, was used to conduct viability analyses for each target and build a situation diagram for the entire park, which links the targets to their threats and other influencing factors. Next, potential restoration strategies were identified for the sand spit. A results chain was created in Miradi to illustrate how each strategy would affect the associated conservation targets and what types of activities would be required to obtain the desired restoration results. This project showcases a successful collaboration between local government, the community, and academic institutions, and offers an excellent example of quantitative, documented restoration planning that combines complex goals into a unified framework
