Aylesford Mountain Nature Reserve protects a remnant tract of mature, mixed forest and some recently harvested land on North Mountain. It is a biologically productive site, with a substantial amount of white ash.

The designation of this site complements private land conservation of adjacent properties acquired and protected by the Nova Scotia Nature Trust (NSNT). It is the only nature reserve in Kings County.

The boundaries were expanded through the survey process to coincide with the extent of the Crown land parcel. This change was made to simplify surveying and management of the site. The reserve does not affect use of adjacent roads (Barley St. and Beckwith Rd.).
