Fig. 1From: Two decades of variable retention in British Columbia: a review of its implementation and effectiveness for biodiversity conservationPercent of total harvested area using variable retention (line) and area harvested (bars) using different variable retention types over 20 years by MacMillan Bloedel/Weyerhaeuser/Cascadia (1999–2006) and Western Forest Products (2007–2018) in BC Coastal forest operations. Total area through 2004 includes private lands (now Island Timberlands). Group = aggregated retention with groups predominantly 0.25 ha or larger; Dispersed = single trees or small clusters of trees spread across a cutblock; Mixed = both group and dispersed retention in the same cutblock; Other = patch cut, shelterwood or selection systems (with long-term reserves). Retention type was not tracked after 2008 because nearly all VR was aggregated retentionBack to article page
