CLOCA Targeted Terrestrial Natural Heritage System

Click to view Metadata The Targeted Terrestrial Natural Heritage System (TTNHS) is determining where additional natural cover should occur adjacent to the FNHS, in order to achieve watershed health targets. CLOCA adapted the Targeted Terrestrial Natural Heritage System (TTNHS) as developed by the Toronto Region Conservation Authority (TRCA), with minor changes to reflect local conditions for CLOCA watersheds. The approach used in defining the TTNHS is broken into three components: 1) evaluation of current habitat patch characteristics using landscape metrics; 2) determining the targeted condition for the landscape; 3) identifying protection and restoration opportunities to reach the predetermined target condition for the watersheds within the CLOCA jurisdiction.
