General Information

One of the most striking characteristics of St. Johns Conservation Area is the predominace of a natural hardwood forest stand.  This area is part of a relatively small Deciduous/Carolinian Forest Region in Canada. The Carolinian Forest Region is characterized by an abundance of broad-leafed species and a scarcity of evergreens.  Over 400 species of vascular plants have been identified, growing in their natural setting in this area.  As well, more than 80 mushroom species have been identified here.


The abundance and diversity of naturally occurring vegetation creates ideal wildlife habitat.  Consequently, this area is richly endowed with wildlife resources including upland and small game, ungulates, reptiles, amphibians, aquatic life, and many resident and migratory bird species.  The main pond has been home to at least one family of Canada geese for many years. 


Mature Carolinian forests, wetlands and pond environments attract waterfowl and other species.  Rare and endangered species have been recorded nesting at St. Hons.


St. Johns Conservation Area forms the headwaters for one of the tributaries of Twelve Mile Creek, Niagara’s only cold-water creek historically notes for its quality trout fishing.  Twelve Mile Creek was one stimulus for the creation of the 0.75 (1.85 acre) man-made trout pond at St. Johns.  A smaller spring-fed pond, formerly a gravel pit, has been used for rearing trout fingerlings, in conjunction with commercially raised rainbow trout, to stock the main pond for the annual trout fishing season.  Trout prefer cool, well oxygenated, clear, flowing water.


Fishing for rainbow trout is allowed here the in Twelve Mile Creek Pond and it is stocked twice annually. This area has 2 wheelchair accessible fishing piers and accessible boardwalk that circles around the little lake. Last Saturday in April through trout season. A fishing license is required with a limit of two fish per person, but check for regulations as the limit is subject to change.


Note: 'St. John's' is variously spelled St Johns, St. Johns, St. John's, St Johns, and St John's.
