ESRM 410 Forest Soils and Site Productivity2011 Nutrient Limitation ‘What if Scenario’
Cedar River Watershed – plots just located upstream of ‘you are here’ pointer
This slide and some following contain the design, stand characteristics and initial growth results. Please concentrate on explaining factors that might have led to the differential growth of Douglas-fir vs. red alder on each site and also the differential growth of each species on different initial site (i.e. RA-RA vs. DF-RA – Group 1 orally presents Friday and RA-DF vs. DF-DF – Group 2 orally presents Friday). Figure 1. Layout of study.
Table 2. Stand C distribution in the 50-yr-old Douglas fir and red alder stands. Tree and understory C concentrations were assumed to be 500 mg C kg-1. Where possible from sampling procedure, variability between plots was assessed and means compared via two-tailed two-sample t-test (Freund, 1988).
