In 1993 the Government of Nova Scotia passed the Conservation Easements Act . As a result an additional different form of conservation easement exists here. The most common example is an easement which permits the benefactor to cross the grantor's property to access his own. Easements are usually registered with the deed to ensure they are respected by subsequent landowners.
Conservation comes into it when the purpose of the easement is to conserve.
As an example consider a stream that provides drinking water. The easement might prohibit altering the watercourse or volume of flow, or cutting trees which provide shade to keep it cool. While easements do not affect the ownership of the land, they may limit the rights of the landowner. In the first example, the grantor could not build a wall and block the benefactor's access. A wall with a gate might satisfy both parties.
