Habitat Banking

»Posted by on Jan 18, 2013 in Posts | Comments Off

Habitat Banking Habitat Banking is the creation or enhancement of natural environment habitats prior to causing losses of habitat through development (e.g., urban area expansion). The new or enhanced habitat is the “bank” that is drawn against for losses incurred through other developments. The legal notion of habitat banking is being explored by Fisheries and Oceans Canada, now, and it may become a regulatory tool that industry (and government) can use to compensate for losses to natural habitat in an expedient way. In the absence of formal regulatory tools, habitat banking is already implemented in various and less-formal ways in Canada. Kilgour & Associates Ltd. has been fortunate to be involved in various projects that have involved some form of...

Spanish River Lake Sturgeon

Spanish River Lake Sturgeon Kilgour & Associates has completed two years of studies of Lake Sturgeon and Walleye on the Spanish River. Our work has identified and quantified spawning areas for both species in the vicinity of hydro generation facilities on the Spanish River, and sturgeon spawning areas on certain parts of the Spanish River. With Coldwater Consulting and C. Portt and Associates, we examined the effects of hydro operations on spawning habitats of Lake Sturgeon at the base of two generation facilities. A summary of our work was presented at the Great Lakes Lake Sturgeon Coordination Meeting that was held in Sault Ste. Marie, Michigan, in early December 2012. The image below illustrates the results of our work,...

MTO Certification Kilgour & Associates is pleased to announce that it has been approved by the Ontario Ministry of Transportation to provide Consultant Services in Natural Sciences and Environmental Inspection During Construction for provincial highway projects. Two of our staff (Kilgour, Francis) are trained as Fisheries Specialists under MTO’s program. We have provided our services on road projects in the Ottawa Region, including the provision of fisheries mitigations for the reconstruction of the Jockvale Road Bridge over the Jock River, and a species at risk inventory for a culvert installation on Anderson Road. We have the largest team of ecologists in the Ottawa region, and can respond quickly to local inventory requirements quickly, ensuring...

Water Quality Index

Canadian Water Quality Index (WQI) Our work on the Canadian Water Quality Index We recently completed an analysis of the Canadian Water Quality Index (WQI), examining its sensitivity to episodic, high-flow events. We used total suspended solids and turbidity as indicators of high-flow events, and found that removing episodic events improved the degree of correlation the index had with indices of benthic invertebrate community composition. Our work is In Press with the Water Quality Research Journal of Canada. The citation is: Kilgour, B.W. A.F. Francis, and V. Mercier. 2012 Reducing the Sensitivity of the Water Quality Index to Episodic Events. Water Quality Research Journal of Canada,...

KAL Resources: office and gear Kilgour & Associates recently moved into 4,000 s.f. of office space at 2285 St. Laurent Boulevard in Ottawa (Unit 16, Building C). The move now provides us with over 1,000 s.f. of warehouse space, which was badly needed to provide local storage for our boats, backpack shockers, water pumps, and other field equipment including water quality meters. The space also includes offices that are set up for processing fish and benthic macroinvertebrate samples. We have a selection of dissecting and compound microscopes for identifying benthic macroinvertebrates. We have various microbalances for weighing small tissue samples, and sediment shakers for grain size analysis.

Ecological Benefit of the Road Salt Code of Practice

»Posted by on Oct 10, 2012 in Posts | Comments Off

Our work on the Road Salt Code of Practice The Road Salt Code of Practice was implemented by Environment Canada in 2004 in response to road salts being declared a toxic substance. We have been working with Environment Canada since 2008 developing an approach to assessing the potential ecological benefits of the road salt code of practice. Our proposed methodology and associated results are about to be published in the Water Quality Research Journal of Canada in an upcoming issue. Our method used species sensitivity distributions to estimate the percentage of species that are likely to be influenced, negatively or positively, by a change in chloride concentration. Road authorities in Toronto predict a 20% reduction in the use of road salt with best practices....
