Algonquin is renown for the beauty and variety of its plant life. Host to more than 1000 species of both plants and fungi there is a huge diversity on offer. The Park lies in a broad transition zone where deciduous forests of Sugar Maple, Yellow Birch and Beech meet coniferous forests of pine, spruce and balsam fur. The Park is host to 34 species of orchid. The Observatory borders the Lake Lavieille Hemlock Wilderness zone and the Eustache Lake nature reserve zone to the West. The Lake Travers sand dune complex and De Geer Moraines lie immediately to the East of the Observatory on Lake Travers. The Greenleaf Creek Watershed surrounding Barron lake is to the South of the Observatory.
