Re: Road Kill



Hello.  Your clients might consider reviewing and modifying their use of 
road salt during winter months. By spreading salts on roads we basically 
create artificial salt licks.  Combined with various other behavioral 
factors, road salt deposits may draw wildlife to road sides and increase 
the risk of animal-vehicle collisions.

For a good general discussion of all the environmental impacts of road 
salts, see Environment Canada's "Canadian Environmental Protection Act, 
1999, Priority Substances List Assessment Report: Road Salts" at:
http://www.ec.gc.ca/substances/ese/eng/psap/final/reports/Road_salt.pdf
In particular for your purposes, see section 3.6.1 "Exposure 
characterization" and 3.6.1.1 "Mammals"--this last section provides 
references to studies on the contribution of road salt to road kill of 
mammalian species (beginning on page 130 of the PDF file).

Beyond any potential impact of road salting practices, for long-term 
reduction of road kill, your clients may simply want to consider statistics 
on which species account for the highest percentage of road kill incidents, 
and perhaps even consider the locations where the highest number of vehicle 
collisions take place.  They might then consult with a wildlife biologist 
and take into account behavioral patterns of those particular species to 
try and come up with targeted prevention strategies.  (I suppose this boils 
down to "Why does this particular chicken cross the road and how can I 
encourage it not to?")
