Description

Tolman Bridge, is located in the valley of the Red Deer River, 18 km (10 miles) east of the town of Trochu. The bridge and adjoining Park land are in the north half of section 14, range 22, township 34, west of the Fourth Meridian. The coordinates at the bridge are 51.503N and 113.009W. The elevation ranges from around 600 m at the river to 800 m or so near the top of the river breaks. In a Natural Area Inspection Report dated 25 June 1982 and in the 1989 Trochu 82 P/14, 1:50,000 topographic map, the land southwest of the bridge was designated as the “Tolman Bridge Municipal Park” while that southeast of the bridge was referred to as the “Tolman Bridge Recreation Area”. In an Alberta, Department of the Environment, Parks and Protected Areas Division paper dated 9 May 2000, the areas on both sides of the river are included in “Dry Island Buffalo Jump Provincial Park”. Campgrounds are found in both areas and they are patrolled by a Conservation Officer stationed in Drumheller.

Description

The writer, now retired and living in Erskine, Alberta, has had a long-time interest in the natural flora and fauna of the province. In the spring of 2000, he commenced an examination of the moths of south-central Alberta, the purpose of which was to document the species present in various natural areas. He is a member of the Alberta Lepidopterist’s Guild, the purpose of which is to encourage the study of Alberta’s moths and butterflies. There is still much to be learned about the distribution and status of lepidopteran (moth and butterfly) species in south-central Alberta. Baseline studies provide information that helps characterize those species associated with various ecoregions, in the present case Prairie; determine status designations (abundant, common, rare, endangered) of various species; and allow the examination of many other parameters, including phenology, dry vs. wet years, and outbreaks of various species such as forest tent caterpillars.

Description

Three hundred and nineteen species of moths and 4 butterflies are reported from the Lowden Springs Conservation Area. Most collections were made at night and, therefore, butterflies and day-flying moths are underrepresented. If all species in the undetermined categories were named, the actual total would be over 350. With further study and names on all of the undetermined specimens, the total would probably be close to 500 species of moths. To put things into perspective, Pohl et al (2010) document 2367 species of Lepidoptera for Alberta. It was especially encouraging to have a first for Alberta (Sparganothis directana) plus several discoveries of seldom encountered species, such as Xenotemna pallorana, Sciota fernaldi, Lipographis fenestrella, Escaria homogena, Heliothis phloxiphagus and Schinia meadi. The list of species would have been considerably greater if the area had additional habitats such as woods or a riverine community but, at the same time, it is quite interesting to...

Description

The Weidemeyer's admiral is a Species of Special Concern in Alberta because its breeding range is limited and it is found only in the Milk River Basin of southern Alberta. This plan provides background information on the species and outlines a set of objectives and management actions to help meet the goal of maintaining current distribution and breeding populations of the butterfly in Alberta. Conservation management plans are developed for Species of Special Concern in Alberta, to provide guidance for land and resource management decisions that affect the species and their habitat. They are intended to be a resource tool for provincial and regional fish and wildlife, land and resource management staff.

Description

An ecological survey of the Park by Kondla & Smith (1972) came up with an impressive 148 species of birds, 25 of mammals, and 225 of flowering plants. Later studies by Wallis (1977), Nordstrom and Wilkinson (1980), Campbell (1983) and Lohr (1993) have added to these totals. The present report incorporates all information in the earlier reports (Bird 2002, 2003, 2004, 2005) as well as making a few corrections and adding new information based on studies carried out in 2005.

Description

The purpose of the lepidoptera survey in Willmore WP was to provide an annotated summary of the species that occur within the park, including notes on such parameters as relative abundance, distribution patterns, range extensions and any other relevant biological or behavioural information. This information will contribute towards an increased understanding of the species occurring in the park as well as in a broader context of Alberta.

Description

Provincial Parks and other areas where natural vegetation is protected are of great value as the flora and fauna present in them is typical of what was in Alberta before widespread agricultural activities replaced them with flora and fauna that was reduced in numbers and made up of species that were associated with cultivated grains and hay crops. As a result, many of Alberta's "rare and endangered" species are now found only, or mainly, in such protected areas. There is still much to be learned about the distribution and status of lepidopteran (moth and butterfly) species in south-central Alberta. Baseline studies of this sort provide information that helps characterize the species associated with various ecoregions, in the present case Aspen Parkland; determine the status designations (abundant, common, rare, endangered) of various species; show the effects of grazing on species composition and abundance; and allow the examination of many other parameters, including phenology, dry...

Survey of the Lepidoptera fauna from the Holmes Crossing Sandhills Ecological Reserve, the Fort Assiniboine Sandhills Wildland Park, and nearby areas

Description

The Holmes Crossing Sandhills Ecological Reserve (ER) is 8 km southwest and the Fort Assiniboine Sandhills Wildland Provincial Park (WPP) is 9 km east of Fort Assiniboine; both are located within the Central Mixedwood Subregion. Holmes Crossing Sandhills ER occupies 1982 hectares and Fort Assiniboine WPP occupies 7903 ha. The latter area was the focus of a Lepidoptera survey in 2005. Both areas contain a number of vegetated transverse sand dunes dominated by stands of jack pine. Other habitats include aspen forest, dry meadows, fens, marshes, bogs and a series of riparian balsam poplar and alder forests. The purpose of this survey was to provide an annotated summary of the Lepidoptera species that occur in these areas, including notes on such parameters as relative abundance, distribution patterns, range extensions and any other relevant biological or behavioral information. This information contributes towards an increased understanding of the Lepidoptera fauna found in this region...

Description

This wildlife status report looks at the Weidemeyer's admiral, a butterfly whose distribution within Canada is limited to two groups of known populations along the lower Milk River in southern Alberta. The total known population in Alberta is estimated to be a maximum of 3000 adults. It is included on the list of species that may be at risk in Alberta. This report is part of the Alberta Wildlife Status Report series, which provides comprehensive summaries of selected wildlife species intended to be useful to those managing populations of species and their habitats, and to help identify species that may be formally designated as endangered or threatened.

Description

The Birch Mountains to the northwest of Ft. McMurray are located within the Upper and Lower Boreal Highlands Subregions . A sizeable protected area, the Birch Mountains Wildland Provincial Park (WPP), is located primarily within the bounds of the Upper Boreal Highlands Subregion. The WPP contains extensive bogs, patches of pine, aspen and birch forest as well as riparian meadow habitats. The park occupies an area of 144,505 ha and was the focus of a lepidoptera survey in 2004. The Upper Boreal Highlands Subregion is characterized by steeply sloping dissected plateaus and undulating and hummocky upper plateau surfaces. In addition to the Birch Mountains, the Upper Boreal Highlands Subregion includes the upper slopes and plateaus of the Buffalo Head, Naylor and Clear Hills. This Subregion is entirely surrounded by the Lower Boreal Highlands Subregion.
