An invasive plant is creating growing concerns for biodiversity across Nova Scotia, as multiflora rose spreads through forests, fields and other natural areas. While its delicate white or pink flowers may appear attractive, the aggressive shrub can form dense, thorny patches that crowd out native plants and disrupt local ecosystems.
Multiflora rose was introduced from Asia and was once valued for uses including ornamental rose rootstock, erosion control and creating natural livestock barriers. However, its ability to spread rapidly has made it a significant invasive species management challenge. Birds can eat its berries and transport the seeds to new locations, while disturbed soil and equipment can also contribute to its spread.
Ecologists and volunteers in Nova Scotia are working to control multiflora rose through methods including hand removal, cutting and specialized root-pulling tools. Because the plant can regenerate, long-term management and repeated efforts are often necessary.
For gardeners and property owners, choosing native plants, avoiding invasive species and learning to identify problematic plants can help protect native biodiversity, pollinators and wildlife habitat. As invasive plant control becomes increasingly important, thoughtful landscaping choices can play an important role in supporting healthier Canadian ecosystems.
