A sensible climate solution for the boreal forest
Astrup, Rasmus Andreas; Bernier, Pierre Y.; Genet, Helene; Lutz, David A.; Bright, Ryan M. (Journal article; Peer reviewed, 2018-01-02)Climate change could increase fire risk across most of the managed boreal forest. Decreasing this risk by increasing the proportion of broad-leaved tree species is an overlooked mitigation–adaption strategy with multiple benefits. -
