Invasive invertebrates other than insects and spiders
Invasive invertebrates other than insects and spiders are from one part of the world that are transported, or migrate due to climate change, beyond their natural range and become established in a new area where they can cause potential harm to native ecosystems.
There are 5 priority categories for invertebrates which determine the province's response. They are:
- Early detection and rapid response (EDRR)
- Provincial containment
- Regional containment/control
Species determined to be high risk to B.C. and not yet established. Management objective is prevent the introduction and establishment.
Conrad's false mussel
Procambarus fallax f. virginalis
Rusty crayfish (PDF, 540KB)
Spotted Lantern fly
Zebra & Quagga mussels
Dreissena polymorpha & bugensis
Species is high risk to B.C. and is new to the Province. Management objective is eradication.
European brown garden snail (PDF, 143KB)
Red swamp crayfish (PDF, 919KB)
Species is high risk with limited extent in B.C. but significant potential to spread. Management objective is to prevent further expansion into new areas with the ultimate goal of reducing the overall extent.
Asian clam (PDF, 500KB)
Chinese mystery snail (PDF, 569KB)
New Zealand mudsnail
Species is more widespread but may be of concern in specific situations with certain high values - e.g., conservation lands, specific agriculture crops. Management objective is to reduce the invasive species impacts locally or regionally, where resources are available.
Banded garden snail
Arion spp. (rufus and vulgaris)
