Spring emergence and abundance of Nebria brevicollis in Burnaby, British Columbia

Nebria brevicollis is a recently introduced ground beetle from Europe that is rapidly expanding its range in British Columbia. Whether Nebria brevicollis can be considered an invasive species in British Columbia has yet to be determined. This research project takes a preliminary look at when in the winter/spring Nebria brevicollis becomes or is active as well as where it is abundant. Through the use of pitfall trapping at three different sites in Burnaby, British Columbia, general timings of emergence and trends in preferred habitats were observed. While more data is needed, early observations point to Nebria brevicollis' activity beginning in mid-February and is more abundant in disturbed and anthropogenic environments. These traits exhibited by Nebria brevicollis are characteristic of an invasive species. However, more research needs to be done to determine if Nebria brevicollis has deleterious effects on humans or native biota.
