2024/3/5
Low productivity caused by paludification in some parts of the closed black spruce (Picea mariana (Mill.) B.S.P) dominated boreal forest threatens the provision of ecosystem services, including wood f...
Addressing spatial variability in provenance experiments exemplified in two trials with black spruce
Picea mariana (Mill.) provenance research REML spatial variation
2015/3/6
Two exemplary black spruce (Picea mariana [Mill.] B.S.P.) provenance trials were analyzed using traditional and spatial techniques. The objective was to find out possible differences between these app...
Identifying the determinants of windthrow damage in wildlife tree patches in the Boreal White and Black Spruce biogeoclimatic zone of northeastern British Columbia
Boreal White and Black Spruce (BWBS) northeastern British Columbia wildlife tree patch windthrow
2010/8/31
Leaving wildlife tree patches (WTPs) has become a common strategy employed to maintain biodiversity among managed forest ecosystems in British Columbia. High levels of wind damage have been observed i...
