Evaluating the effectiveness of climate-based seed transfer and assisted migration: a case study of lodgepole pine (Pinus contorta var. latifolia Dougl.) and interior spruce (Picea engelmanii x glauca (Moench) Voss and their hybrids) in western Canada

Table 3 Summary of the pooled height transfer function analysis for lodgepole pine and interior spruce

Species	Site climate variable	b_o	b₁	df	No. sites	RMSE
Lodgepole pine	MCMT	3.3807	0.0351	1835	42	14.0
Interior spruce	TD	5.1272	− 0.0512	623	5	13.9

Pooled height transfer function relates genetic suitability (i.e., HTp, population height relative to local population height) to Euclidean climate transfer distance and site climate in a half normal function (Eqs. 1 and 2). b₀ and b₁ are parameter estimates. df is residual degrees of freedom. No. sites refer to the number of retained test sites. RMSE is the root mean square error of the transfer function
