... temperature and humidity (for at least the age of the saplings)? These factors can vary greatly, both seasonally and annually; hence it is possible that a twelve-year-old sapling spent the first half of its life in dry conditions and the second half in waterlogged conditions. It is likewise conceivable that certain saplings only experienced occasionally waterlogged conditions for short periods of certain years. This notion, combined with the age variance, could significantly 'contaminate' the data for each group. The comparison of data between wet and dry saplings of comparable age (across the age range) would lessen the potential for inaccuracy. Likewise, ascertaining the level of environmental stability experienced by the saplings throughout their lives would also lessen the potential for inaccuracy Conclusion: The 't-tests' conducted upon the results (Appendix 'B') proved very conclusive: only one of the twelve features tested scored a significance less than 'P <0.0001', and that was the 'annual ...
