CSISS conducts all activities within the boundaries of the Columbia Shuswap Regional District.
The region we work in is broken up into three ‘Invasive Plant Management Areas’ (IMPA’s). The label “IPMA” is used even though it is understood that management strategies expand to include non‑plant invasive species.
