Macroinvertebrate Surveys of Nature Saskatchewan Sanctuaries

Nature SK Map

Nature Saskatchewan has a number of wildlife sanctuaries around the province that have aquatic habitats within or adjacent to them: Turtle Lake (TL), Red Deer River at Rendek Elm Forest (RDR), Meadow Bank Lake at Van Brienen Land (VBL); and Crooked Lake Fen (CLF). As part of the process to inventory the biodiversity of the plants and animals at these sites Nature Saskatchewan retained the services of AquaTax Consulting to conduct a survey of the aquatic macroinvertebrates associated with the sanctuaries. The sanctuaries were surveyed during 2000, 2001 and 2002 thanks to funding provided by Saskatchewan Energy. Field assistance was provided by J. Halpin, V. Keeler and J. Webb. J. Halpin aided in processing the samples.

Turtle Lake Sanctuary (TL):

Turtle Lake

This sanctuary runs adjacent to a portion of the East shore of Turtle Lake. The lake is typical for the parkland boreal transition zone. It has reed beds along the shore and a sandy silty substrate. Wave action can be relatively intense along the shore creating piles of broken and decaying reeds. Cottage developments have impacted the shoreline to some extent. During 2002 drought conditions in the region resulted very low water levels in the lake and forest fires in the vicinity. The lake was so shallow that 300 meters from shore the water was not 1 meter deep. About 58 macroinvertebrates have been collected from the lake's shallow water and shoreline adjacent to the sanctuary.

Frog Pond at Turtle Lake Sanctuary (TL):

In addition to the Turtle Lake itself, Turtle Lake Nature Sanctuary also has a small Frog Pond (53-36-13 N 108-35-24 W). This little pond was created when workers digging for gravel hit a natural seep. The sides are steep and subject to caving in. Water depth was in excess of 1 meter in 2001, but due to drought conditions in 2002 the water level has declined by 70% and likely was dry by fall. The bottom is organic silt and sand. Cattails along with a number of submerged plants are present. Sixty-nine taxa of macroinvertebrates were collected from the frog pond.

Crooked Lake Fen Nature Sanctuary (CLF):

Crooked Lake Fen Sanctuary is located on the north bank of the Qu'Appelle River spillway. A number of springs emerge from the slope and flow under ground, periodically coming to the surface to form small pools and tiny streams. These features have created an extreme-rich fen in portions of the sanctuary. At the bottom of the slope a small, shaded, cold stream collects and flows to the river. The conditions within the sanctuary provide habitat for balsam poplar, Manitoba maple, cattail/reed grass marsh, sedge meadow and wet shrub land and many rare plants. Although the area of surface water is small, the streams and pools have a surprisingly diverse macroinvertebrate fauna.

Red Deer River, Rendek Nature Sanctuary (RDR):

At the access point to the Red Deer River from the sanctuary the substrate is small (4 cm stones) to large (25 cm rocks) cobble with silt in areas sheltered from the current.Salix sp stands bordered both shores of the river. Spring 2001 water depths ranged from 10 to 60 cm over the cobble to 1.5 meters (estimated) in the channel between the island and far shore. By late September the river was reduced to small trickles of water between isolated pools and people were driving across the riverbed. Low snowfall during the winter of 2001/02 and continued drought conditions in the spring and summer of 2002 resulted in the river being reduced to just a few channels by August 2002.

On the visit in August 2002 the water level was low and algae mats were common in the channels. Leopard frogs and Canadian toads were very abundant along the shoreline. In some parts more than three per meter were observed. There were also large numbers of yellow/red dragonflies (Sympetrum costiferum). Of particular interest were large numbers of water scorpions (Ranatra fusca: Nepidae) and giant water bugs (Lethocerus americanus: Belostomatidae).

Over 110 taxa have been identified from the material collected from the river. The most diverse group were the insects with at least 70 species identified.

Meadow Bank Lake Van Brienen Land (VBL):

The sanctuary is dominated by a trembling aspen and Manitoba maple wood lot. A small lake, really a large slough, called Meadow Bank Lake, borders the North edge. Two farmyards border the north shore of the lake. The shoreline is almost entirely ringed by a band of emergent vegetation dominated by Scirpus validus. Submerged vegetation included Myriophylum sp, Lemna trisulcus and Chara sp. Near the east edge of the sanctuary is an active beaver lodge. The substrate is firm and made up of clay, silt and sand with many embedded rocks and boulders. Near the centre the substrate is organic ooze about 40 cm deep. Decaying logs from beaver activity litter the bottom.
