The Atlantic Canada Conservation Data Centre (AC CDC) was established in 1997. It became a member of NatureServe in 1998 and NatureServe Canada in 1999, was incorporated as a non-profit organization in 1999, and became a registered charity in 2000. Like all Conservation Data Centres, our staff gather, maintain, and update spatially accurate occurrence data for species and ecological communities of conservation concern.

The AC CDC's mission is to assemble and provide objective and understandable data and expertise about species and ecological communities of conservation concern, including those at risk, and to undertake field biological inventories in support of decision-making, research, and education in Atlantic Canada.
