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:
- Prevent
- Early detection and rapid response (EDRR)
- Provincial containment
- Regional containment/control
- Management
Prevent
Species determined to be high risk to B.C. and not yet established. Management objective is prevent the introduction and establishment.

Early detection and rapid response (EDRR)
Species is high risk to B.C. and is new to the Province. Management objective is eradication.

Cornu aspersum
Red swamp crayfish (PDF, 919KB)
Procambarus clarkii
Provincial containment
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.

Corbicula fluminea
Cherry shrimp
Neocaridina davidi

Bellamya chinensis
New Zealand mudsnail
Potamopyrgus antipodarum
Management
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
