Here's how Vancouver's rain gardens are giving salmon a boost
Strategically placed rain gardens in the City of Vancouver can prevent flooding and reduce infrastructure costs. But the salmon are benefitting from these even more
Specially designed rain gardens can reduce toxic chemicals that are entering streams by more than 90 percent, a new research has found.
Researchers from the University of British Columbia say that if the chemicals have to pass through rain gardens first, they are absorbed in the garden's trees, plants, and soil, with only about five percent of it actually making its way into river streams.

As it stands now, 6PPD Quinone, a chemical in car tires, has been found to kill high amounts of coho salmon in very small quantities.
The researchers are working with the city to find the best places to build these rain gardens in hopes of protecting salmon populations.
