Ongoing dendrochronological studies of Kluane Lake stumps and driftwood (Van Dorp, 2004) will allow a more detailed evaluation of the timing of these events and of Bostock's hypothesis.
While our results cannot be used to predict tree growth or streamflow because the chronology lengths were not adequate for model verification, we have shown that black walnut is a suitable species for dendrochronological studies and it may be specifically useful for climate or streamflow reconstructions where long chronologies are available.

Since all birch remnants were strongly decayed, tree rings were not discernible, which excluded dendrochronological dating.
The place is also dated by dendrochronological analyses, taken from altogether 154 samples.
Dendroclimatological studies at coastal sites have been relatively rare in the past because of the widespread belief that trees from such sites are not sensitive to climate variability, not easily datable using dendrochronological techniques, and short-lived.

In contrast to the dendrochronological investigation, which emphasizes the process of change, the third investigation is intended to identify changes in the pattern of land cover--specifically tree cover--that have occurred at the forest-tundra ecotone.
