# Marie-Jean-Eudes Ecological Reserve

The Marie-Jean-Eudes Ecological Reserve constitutes a public conservation, education and research. Its territory is located in the township of Desaulniers, in the unorganized territory of the regional county municipality of Maskinongé, in the administrative region of Mauricie, in Quebec, Canada. This ecological reserve is enclosed in the eastern part of the Mastigouche Wildlife Reserve.
Its raison d'être of the Marie-Jean-Eudes Ecological Reserve is to ensure the protection of ecosystems representative of the ecological region of the Middle Laurentians of Mauricie, which belongs to the sugar maple-yellow birch domain.
This small reserve of 8.32 km$^2$ (3.21 sq mi) is administered by the Quebec Ministry of the Environment.

## Understand
### History

This ecological reserve was created in 1992. It was named after Sister Marie-Jean-Eudes (née Marie-Bernadette-Eugénie Tellier) (1897-1978), a botanist. Tellier is considered a pioneer in the study of natural sciences in Quebec. In particular, she worked for more than 30 years in the field of scientific popularization within the Circle of Young Naturalists. Several articles in biology, geology and especially botany, have been published under his pen.

### Geography

On the south side, its territory is delimited by Lake Gauthier and Lake Shawinigan; on the east side, by Lac Brodeur. This territory includes the Girard, Bellemare, Hector, Gélinas, Cresson and Merle lakes. In short, this territory is at the eastern limit of the Mastigouche wildlife reserve, therefore very close to the western limit of La Mauricie National Park.
The relief of this reserve in the middle Laurentians is hilly. Topographically, the altitude of this reserve varies between 335 m, near Lake Shawinigan, about 489 m to the northwest. According to specialists from the Ministry, the source rock of the reserve is mainly composed of gneiss, original rocks formed in the Precambrian period. On the surface of these rocks, the last glaciation left sand-textured tills, thick on the slopes and thinner towards the summits. The territory of the reserve also includes fluvio-glacial sands and gravels in the valley bottoms, as well as recent peat deposits in poorly drained basins. While the soils mainly contain Dystric Brunisols and Humo-Ferric Podzols.
Stands dominated by deciduous trees and those dominated by coniferous trees are approximately equivalent. Among the deciduous group, the sugar maple-yellow birch grove occupies the slopes facing south and west. The sugar bush, yellow birch and large-leaved beech colonize areas of altitude above 400 m. On the other hand, the conifer group is divided into four stable stands: pure black spruce, balsam fir-black spruce, black spruce-white pine, and balsam fir-yellow birch.

## Get in

From the reception stations of Pins Rouges of the Mastigouche Wildlife Reserve, the trip by the forest road is 36.4 km (22.6 mi) to the bridge over the outlet of Lac Gauthier. In the Mastigouche wildlife reserve, all you have to do is take the forest road along the Loup river, then the forest road passing near Lac Jouet, Lac du Pimbina, to Lac Shawinigan; then take the branch leading to the west shore of Lac Brodeur. A segment of the forest road passing on the north side of Shawinigan Lake more or less constitutes the southern limit of this reserve; this forest road leads to a small resort hamlet on a peninsula (attached to the north shore) between Lake Shawinigan and Petit lac Shawinigan.
