The City of Calgary has selected four priority sites to be the focus of riparian rehabilitation. Our goal is to build a more resilient and diverse ecosystem, able to resist the impact of floods, people and wildlife. Restoration techniques are designed specifically for each site in order to promote river bank resiliency, and increased protection against on-going erosion and future flooding.
The goal of this project is to rehabilitate the degraded riparian ecosystem on the banks of the Bow River, and to slow the invasion of common Caragana in the meadows of Edworthy Park. Historically, this site has seen heavy use by people visiting the park and rural agricultural creating an ecosystem dominated by non-native species.
This project is also located on the south side of the Bow River within the Edworthy Park. The issue here are two invasive plant species - common Caragana, which dominates much of the river bank, and smooth brome, which is taking over the rest of the site. The objective of restoration is to slow and possibly stop the incursion of the invasive species, creating a more biodiverse and resistant ecosystem.
The Valley Ridge Site is located within the Valley Ridge Golf Course, and will be constrained to ensure work does not affect operation of the golf course. This site rates as "unhealthy" as it has been largely altered by golf course development. The tree community consists mostly of mature balsam poplars and some mature cottonwoods, with little poplar regeneration as they have been mechanically removed. Work here will focus on re-establishing the natural forest ecosystem of this area.
This site is located within the sensitive riparian forest along the Bow River directly down river from the Bearspaw Dam and within the private property of TransAlta Corporation. It rates as "healthy, with problems" due to recreational use of the area, as well as the prevalence of invasive plant species. This location will benefit from cluster planting of native species in order to reclaim disturbed areas and enhance the natural riparian forest.
These projects will begin in late September and run through to the middle of November.
