Coastal sand ecosystem restoration
Rare ecosystemThe rare coastal sand ecosystem needs open spaces to function well. The plants and animals that live on dunes and spits depend on the ever-shifting sand to keep patches open, allowing for competition-free growth. The common nighthawk, a species at risk, nests in these open areas.
Crowded outScotch broom and European beach grass have invaded the sand spits on Sidney Island in the park reserve. They crowd out the native plants and animals and hold the sand too tightly with their roots. Often unknowingly, people and dogs trample rare plants and scare birds on the spit.
To the rescueTo protect the species at risk in the coastal sand ecosystem, Parks Canada launched a restoration project. Efforts began at the end of the long spit on Sidney Island, an area called the teardrop.
Many rare plants and animals depend on the teardrop: common nighthawk, contorted-pod evening-primrose, Edwards’ beach moth, silky beach pea, yellow sand-verbena and American glehnia.
Volunteer powerPark staff coordinated teams of volunteers from clubs, schools, universities and community groups. These hardworking people donated thousands of hours to control invasive plants and make space for native plants and animals. They removed all the mature Scotch broom from the teardrop site.
Tiny plant, big recovery!An endangered plant, the contorted-pod evening-primrose, lives in only a handful of places in Canada. It needed extra help to recover on Sidney Spit, so Park staff planted nursery-grown seeds on the newly cleared areas. This tiny plant had a huge recovery. Over 30,000 new plants sprouted, a 980% increase in annual population counts relative to previous years.
Our commitment: to protectOur ongoing efforts to protect this rare ecosystem include installing signs, building fences, monitoring native species and removing invasive plants. At nearby Pacific Rim National Park Reserve, restoration projects are also underway to protect sand dune plants and animals. Learn more.
