Canopy loss was lower for all areas of pre-fire timber harvest (Δ 3.9%CC) than for fire-only, but among harvested areas, the greatest change was observed in the oldest treatments and the most intensive treatments [i.e., stand clearcut (Δ 5.0%CC) and combination of shelterwood establishment cuts and shelterwood removal cuts (Δ 7.7%CC)].
Post-fire timber-production forests (Maritime pines and Eucalyptus) contributed a higher quantity of thinner, longer and straighter DWP to streams than Cork oak stands.
Reconstructions have indicated the difficulty of deliberately firing timbers in this way, particularly in the prevailing climatic conditions in Scotland, and it is more likely that this was done as part of a process of fort destruction, either after conquest or when abandoned by the inhabitants.
Studies of animal responses to fire and timber harvesting in forest ecosystems typically focus on a single level of community diversity.
After the fire exposed timber layer is completely charred and the char-layer has fallen off, the thin vertical timber members are exposed to fire on 3 sides, leading to very irregular residual cross-sections with charring depths much greater than for heavy timber structures.
Romantics heard it in the roar of avalanches, the creak of glaciers, the crackle of fire in timber and the long susurration of waves on the shore.
Surprisingly, community evenness and functional diversity did not show marked responses to fire or timber harvesting.
Four species exhibited significant population responses to either fire or timber harvesting, while the rest were unaffected by either disturbance.
These are forms of forest management associated with either restoration activities (e.g., thinning, prescribed fire) or timber harvest (e.g., clear cutting, selection harvest).
Forest landscape models are effective tools for exploring the effects of long-term and large-scale landscape processes such as seed dispersal, fire, and timber harvest.
In conclusion, aiming to derive useful design suggestions, a possible extension to log-haus systems of the "Reduced Cross-Section Method" (RCSM) currently in use for the verification of fire exposed timber members is proposed.
