(1) Plan and description
(1.1) Geographic location, limits and dimensions
The plan of the Île-Garth ecological reserve and its location are shown on the annexed maps.
The Île-Garth ecological reserve covers the total area of Île-Garth in the Mille Îles river. The island is situated within the limits of Ville de Bois-des-Filion, approximately 2 km downstream from the town of Rosemère. Almost 90% of the island is a flood-risk area. The ecological reserve covers an area of approximately 18 ha.
(1.2) Ecological overview
The ecological reserve is part of the natural region of the Upper St. Lawrence Plain in the natural province of the St. Lawrence Lowlands. It protects three threatened or vulnerable species: black maple (Acer nigrum), hackberry (Celtis occidentalis) and American bladdernut (Staphylea trifolia). The ecological reserve also protects regionally rare forest communities of interest such as white pine, red oak and bur oak stands, and communities of American bladdernut and silver maple with shagbark hickory. It will protect one of the rare riparian forests typical of the Milles Îles river having conserved a high level of ecological integrity and having remarkable floristic diversity.
(1.2.1) Representative elements
The territory is characterized by a moderate climate. It belongs to the bioclimatic field of sugar maple-bitternut hickory stands.
Geology and geomorphology:
The bedrock is formed mainly of limestone and dolostone, carbonatized rock types. The majority of surface deposits on Île-Garth are composed of sediments deposited by the Mille Îles river.
Silver maple stands cover the entire central and eastern part of the island. In the low-lying areas in the interior of the island, poor drainage conditions result in one complex in which the only companion species of trees in abundance are red ash and American elm (Ulmus americana). The herbaceous stratum is made up almost exclusively of sensitive fern.
The highest part of the island, the western tip, is colonized by a white pine stand. Shagbark hickory and American basswood are also relatively abundant.
On the north-eastern part of the island, pioneer species such as white birch (Betula papyrifera) and red maple (Acer rubrum) are found alongside more shade-tolerant species such as butternut and shagbark hickory.
(1.2.2) Outstanding elements
Île-Garth is home to at least three threatened or vulnerable species in Québec: black maple (Acer nigrum), hackberry (Celtis occidentalis) and American bladdernut (Staphylea trifolia).
As for the fauna, the map turtle (Graptemys geographica), a species likely to be designated as threatened or vulnerable in Québec, was spotted in 1985 at the mouth of Aux Chiens creek, located in the vicinity of Île-Garth, and also at other points along the Mille Îles river.
(1.3) Land occupation and use
The land is public property. There has been no development on the island.
(2) Protection status
The Île-Garth ecological reserve meets the objectives for which it is established on the territory, namely:
(1) to conserve the elements constituting biological diversity in their natural state, as integrally as possible and in a permanent manner, in particular by protecting ecosystems and the elements or processes on which their dynamics are based;
(2) to set aside land for scientific study or educational purposes; and
(3) to safeguard the habitats of threatened or vulnerable flora or fauna.
(3) Activities within the reserve
All activities carried on within the Île-Garth ecological reserve are governed by the provisions of the Natural Heritage Conservation Act (chapter C-61.01, s. 48). This conservation plan does not specify any prohibited activity other than those prohibited in ecological reserves by the Act.
(3.1) Prohibited activities
— General prohibitions under the Act
For reference purposes, it is important to note that under the Natural Heritage Conservation Act, the main activities prohibited in an area assigned ecological reserve status are:
— hunting, trapping, fishing, earthwork or construction activities, agricultural, industrial or commercial activities, and generally, any activity likely to alter the state or nature of ecosystems;
— forest development activities within the meaning of section 4 of the Sustainable Forest Development Act (chapter A-18.1);
— mining, and gas or petroleum development;
— mining, gas or petroleum exploration, brine and underground reservoir exploration, prospecting, and digging or boring; and
— the development of hydraulic resources and any production of energy on a commercial or industrial basis.
In addition, no person may be in an ecological reserve, except for an inspection or for the carrying on of an activity authorized under law. The Minister may, however, authorize, in writing and on the conditions the Minister determines, any activity consistent with the purposes of an ecological reserve or with the management thereof.
(3.2) Supervision of activities
The Minister of the Environment is responsible for the application of the Natural Heritage Conservation Act, and is also responsible for the ecological reserves established under that Act. The Minister will supervise and monitor the measures contained in the Act with regard to permitted activities in protected areas.
In addition, the Minister has authority over that land, which forms part of the domain of the State.
