Authors and brothers Dick and Syd Cannings wrote the first edition of the book 20 years ago. While the third and latest edition talks about everything from B.C.'s diverse flora and fauna to rocks and rivers, there is a particular emphasis on how climate change is impacting the province's ecology.
"When the ecologists look back … in the 70s, British Columbia was mapped by Ministry of Forest ecologists into various ecological zones," Syd told B.C. Almanac's Gloria Macarenko.
"Now, when they go back and look at that same system, 23 per cent of the province has moved into a different climate zone."
Dick, who lives in the Okanagan, says he's witnessed longer, hotter summers and more catastrophic fires in recent years.
"Every time there's a fire that burns my favourite forest, the ponderosa pine forest, a lot of that turns permanently into grasslands and that's how these climate zones will change the actual forest zones and vegetation zones of the province," he said.
