WebJun 13, 2016 · Gross annual increment (GAI) can be regarded as composed of change in growing stock, fellings, and natural losses. The demand of forest products, forest services, and many other forest functions influencing forest productivity has increased substantially. WebApr 12, 2024 · The mean interseries correlation indicating local forcing of growth, however, differed among the stands ranging from low to intermediately high in EST_1 and EST_3, respectively. The above-average synchronicity of the datasets suggested that the inter-annual variation of the increment among trees was of a similar phase yet differed in extent.
WebAnnual mean concentrations and annual total loads from 2000 to 2024 were generated by WRTDS models. Trends in concentrations and loads were calculated from streamflow-normalized annual mean concentrations, and annual total loads generated by the WRTDS models along with bootstrapped confidence intervals are displayed in figure 6 . http://nsforestnotes.ca/forestry/mean-annual-increment/
