What is the ER Atlas?
The ER Atlas was first published in 1999 to display inventories of vegetation, animal habitat, ecosystems, and natural features. It has been updated to display more recent data and new inventories. The ER Atlas is for information purposes only. For detailed information on the history of the ER Atlas, please see Saanich Environmental Mapping Backgrounder [PDF - 964 KB].
