Available in PDF, EPUB and Kindle. Book excerpt: seasons (April 1-October 31) are presented for both sites. Maximum T at GS10 and HU10 was approximately 0.8 and 0.7, respectively, and minimum levels in the understorey declined to less than 0.05 at both sites on the south side of the gaps. Growth on the sites was affected by both soil moisture and vapour pressure deficit. An additive model was used to incorporate the moisture variables with T estimates to model the effect of light on growth, although replication was considered insufficient for statistical comparisons between the two sites. Growth tended to increase to a maximum at T values of approximately 0.3 and 0.8 for western hemlock (Tsuga heterophylla [Raf.] Sarg.) and western redcedar (Thuja plicata Donn.), respectively, and did not reach a maximum at approximately 0.8 above-canopy light for Douglas-fir (Psuedotsuga menziesii [Mirbel] Franco) and western white pine (Pinus monticola Dougl.). Light modelling with TASS III revealed both differences and similarities between the mod
