I mentioned it in my opening remarks, but I can summarize.
If the forest is rejuvenated, abundant and physically accessible food resources will suddenly become available to all herbivores, since they will be at a height that's easy to access. These resources are easily digestible because they are low in tannins and lignins. Individuals are therefore able to be in better physical condition and to invest more in reproduction and survival.
White-tailed deer can produce up to three offspring a year, moose can produce up to two offspring a year, and, due to biological constraints, caribou can produce zero to one offspring a year. Population growth therefore won't be the same. Population growth will also lead to an increase in predator abundance, because they also have more food available. Those predators, which are more abundant as a result of logging, will also be more efficient because of the forest roads. My work and that of several other researchers in Canada show that they use low-grade forest roads to more effectively patrol the territory. It's easier for them and us both to walk on a forest road than in the forest. They're going to harvest more caribou, because they are a more vulnerable prey than moose. For that reason, they will cause the adult population to decline, but there will also be fewer young caribou, since the black bear, which is very abundant on young harvest blocks, will be able to feed on caribou more easily. The Government of Quebec has documented this. In areas where caribou are forced to relocate from their home range, caribou become less loyal to their home range, thus increasing the risk of predation for young caribou.
It's as if we were asking someone to quickly find the refrigerator in someone else's house or apartment. That's quite normal. We know the environment, the resources and the risks. This entire cascade of events is amplified in a territory that is subject to highly sustained development or a high regime of natural disturbances.
