Description: Enhancement opportunity areas are areas identified by the conservation authorities as "targeted areas" for restoration/stewardship initiatives that if restored would positively contribute to the natural heritage system. ROP Consolidation September 3, 2024.This layer was created using the Conservation Authority's "targeted NHS" datasets. These datasets were merged together and flattened into one feature. Any areas which fell within the Seaton boundary were removed. Any areas which were already covered by Durham Region's Draft Regional NHS were also removed.

Description: Archaeological Management Plan for the Regional Municipality of Durham ROP Consolidation September 3, 2024.The Iroquois shoreline is the prehistoric shoreline of Glacial Lake Iroquois. This lake existed at the end of the last ice age (approximately 12 000 years ago). The layer was created by determining the edge of the shore by selecting the shorecliffs of the current landscape, which is a characteristic of this particular glacial lake.

Description: Cartographic watercourse layer, based off of MNRF's OHN Watercourse layer. Watercourse are line features (natural and constructed) that describe various realizations of flowing water at a medium scale of 1:10K in Southern Ontario ROP Consolidation September 3, 2024.Using MNRF's OHN Watercourse layer (scale of 1:10K in Southern Ontario), the smoothing tool was applied with a Bezier curve, to produce a cartographic watercourse layer. Additional edits were made by the Region of Durham DMG Department for watercourses within the Urban River Valley areas (from Greenbelt 2017). These edits were to ensure the cartographic watercourse would remain within the limits of the Urban River Valley areas (as the process of smoothing the watercourse adjust the location of the linework in some places).
