An Area of Natural and Scientific Interest (or ANSI) is an official designation by the provincial Government of Ontario in Canada applied to contiguous geographical regions within the province that have geological or ecological features which are significantly representative provincially, regionally, or locally.[1][2][3] Some sites with this designation were assessed through the International Biological Program between 1964 and 1974. As of 2014, over 1000 sites covering 460,000 hectares (4,600 km2) have been designated in the province.[1]
The Conservation Land Tax Incentive Program (CLTIP) is a program offered to landowners whose property includes ANSI land to voluntarily protect that land in exchange for a property tax reduction.[4]
