Vancouver's Still Creek sees salmon for fourth year running
'We can get these kinds of fish back into our city,' says city biologist
Chum salmon have returned to spawn in an urban creek in East Vancouver for the fourth year in a row, leaving biologists feeling "pretty excited" about the potential to return city landscapes to their natural states.
"It really indicates that if we can improve these systems more, if we can work on the watershed, if we can open up stream channels that are buried now, we can get these kinds of fish back into our city," said Vancouver Park Board biologist Nick Page.

Still Creek runs through some of Vancouver and Burnaby's most industrialized areas. Chum salmon hadn't swam their way through there for 80 years until they returned in 2012.
Despite the office buildings, recycling depot, and strip malls that flank its side, the corridor is one of several areas the City of Vancouver has identified as a "hot spot for biodiversity."
As part of its Still Creek Enhancement project, Vancouver has taken steps that include removing concrete, adding native plants, and in some places narrowing streets to widen the stream.
"All that incremental work, plus [the work done on] the fish passages downstream, have allowed the fish to come back," said Page.
He estimates there are currently about 12 to 15 chum salmon in the creek so far this year.
