Fig 6. Estimated growth performance.

Estimated growth performance (as given by dominant tree height H24 or basal area BA24) for populations to be planted at three altitudinal zones (Low: 0–500m; Mid: 500–1000m; and High >1000m) of the case study region under current climate (A, D) and two time slices of a transient climate change scenario (B, E) 2050 and (C, F) 2070.The populations with optimum height and basal area respectively were either drawn from the URF model (= ‘opt’ populations) or drawn from the climate envelope approach which is based on similarity of climate between the study region and the natural distribution of Douglas-fir in Northwest America (= ‘en’ populations).
