The Burnt Lands is an alvar between Almonte and Ottawa near Upper Huntley, Ontario, Canada. [1] It probably obtained its name from one of the forest fires that swept the area during early European settlement.

Contents

It is possible that fires assist in creating or maintaining alvars. However, the shallow soil, with alternating drought and flooding, is likely the main factor. The main point is that in a land that is typically covered in forest, alvars provide small area of open prairie-like conditions for plants that require such conditions.

This alvar is one of the best examples of this habitat type in Lanark County and in southern Ontario. It has been the subject of numerous scientific studies. [2] [3] [4] [5] [6] [7] Because of its significance, The Ontario Ministry of Natural Resources has designated ca 610 hectares (1,500 acres) of the alvar as an Area of Natural and Scientific Interest. A smaller parcel of several hundred hectares is protected within the Burnt Lands Provincial Park (Nature Reserve). [8]

It is a popular destination with local naturalists, including bird-watchers and photographers. [9]

Description

Some of the distinctive plants found here include Cooper's milk vetch [10] and Ram's-Head Ladyslipper. There are 82 breeding bird species and 48 butterfly species. The alvar is thought to have existed in some form since the end of the last ice age, since it has globally rare snails ( Vertigo hannai ) and even a kind of carabid beetle found nowhere else in the world. [11]

The CFS Carp Almonte Detachment (Almonte Antennae Yard), a decommissioned military radio receiver, was located in the alvar. [12]

Threats to the alvar include urban sprawl, subdivisions, quarries, illegal dumping of household trash and construction materials, illegal sand quarrying, and all-terrain vehicles. [12] There is also a problem with jack pine trees, once planted by the Ontario Ministry of Natural Resources, that are now shading out some of the rare plant species; some experts suggest that these trees need to be removed. [13] A fire in 1999 removed some of the encroaching forest and produced open meadows, which, in 2008 had nearly twice the number of plant species as in adjoining unburned areas. [14]

Burnt Lands Provincial Park

The alvar is protected within the Burnt Lands Provincial Park. [15] The park consists of two non-contiguous parcels of land, totaling 516 hectares (1,280 acres) of land. [8]

It is a non-operating park without any visitor activities or facilities. [8]

The Ottawa River is a river in the Canadian provinces of Ontario and Quebec. It is named after the Algonquin word 'to trade', as it was the major trade route of Eastern Canada at the time. For most of its length, it defines the border between these two provinces. It is a major tributary of the St. Lawrence River and the longest river in Quebec.

The Thousand Islands – Frontenac Arch region or the Frontenac Axis is an exposed strip of Precambrian rock in Canada and the United States that links the Canadian Shield from Algonquin Park with the Adirondack Mountain region in New York, an extension of the Laurentian mountains of Québec. The Algonquin to Adirondacks region, which includes the Frontenac Axis or Arch, is a critical linkage for biodiversity and resilience, and one with important conservation potential. The axis separates the St. Lawrence Lowlands and the Great Lakes Lowlands. It has many distinctive plant and animal species. It is one of four ecoregions of the Mixedwood Plains.

<span class="mw-page-title-main">Alvar</span> Limestone-based biological environment

An alvar is a biological environment based on a limestone plain with thin or no soil and, as a result, sparse grassland vegetation. Often flooded in the spring, and affected by drought in midsummer, alvars support a distinctive group of prairie-like plants. Most alvars occur either in northern Europe or around the Great Lakes in North America. This stressed habitat supports a community of rare plants and animals, including species more commonly found on prairie grasslands. Lichen and mosses are common species. Trees and bushes are absent or severely stunted.

As of 2014, over 1000 sites covering 460,000 hectares (4,600 km2) have been designated in the province.
