Found 10 records similar to Aquatic Connectivity - Jasper
This is a multi-park measure, which includes an inventory and assessment of 1,754 culvert and 51 bridge locations along the major highways and roads in Banff, Kootenay, Yoho, Waterton Lakes, Mount Revelstoke, and Glacier national parks. In Glacier National Park the capacity for fish passage above and below each crossing was evaluated for 107 road-stream crossings in 2007, of which 32 were considered likely to support fish passage. In 2017, an additional culvert was added to the inventory, bringing the total road-stream crossing count to 33. Aspects of a stream crossing that may pose a barrier to aquatic connectivity include high water velocity, insufficient water depth, outfall drop, a debris blockage, flow contraction/excessive turbulence, an inlet drop and/or culvert bottom raised above substrate.
This is a multi-park measure, which includes an inventory and assessment of 1,754 culvert and 51 bridge locations along the major highways and roads in Banff, Kootenay, Yoho, Waterton Lakes, Mount Revelstoke, and Glacier national parks. In Mount Revelstoke National Park the capacity for fish in streams above the Trans Canada Highway is limited, yet we have 89 road-stream crossings that have the potential to maintain aquatic connectivity or divert streams if blocked. Aspects of a stream crossing that may pose a barrier to aquatic connectivity include elevated intake, physical blockage, and structural failure.
Aquatic fish data are collected across watercourses in Jasper National Park using a variety of fish sampling methods in order to inventory fish diversity, distribution, and relative densities over time. Data collected provide resource management some of the necessary information needed to prepare stock-specific plans to conserve, manage, and where appropriate restore native fish and their habitats in Jasper National Park.
A Drainage Appliance is an apparatus (that has not been described as a culvert), or earth works, designed to facilitate the movement of water in a controlled manner. Drainage Appliance include some appliances/earth works that work in conjunction with culverts. It is a Point feature
Bank swallows (Riparia riparia) and Barn swallows (Hirundo rustica) have been listed as Threatened species by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC). In Jasper National Park, black swifts nest at variety of sites associated with vertical soil banks, including riverbanks and road cuts. Barn swallows nest at variety of sites associated with vegetation and artificial structures, including meadows and culverts. Data are collected by trained observers during the breeding season to identify breeding sites to inform management action.
This dataset includes all culverts with a span of 2 metresor greater.
A Culvert is a pipe (less than 3m in diameter) or half-round flume used to transport or drain water under or away from the road and/or right of way. Culverts that are greater than or equal to 3m in diameter are stored in the MoT Bridge Structure Road Dataset. It is a Point feature
This dataset includes all culverts with a span less than 2 metres.

Number of municipally owned bridges, culverts and tunnels in all provinces and territories, by urban and rural and population size.
