In the last 20 years it has been shown to the point of being a science proof that top predators are actually the keystone animals of any ecosystem, and that removing the keystone animals will insure that ecosystem will be destroyed.

"Currently, the silvicultural systems used in Algonquin Park include the selection system, uniform shelterwood system, and patch clear-cut-ting. The selection and uniform shelterwood systems are the principal silvicultural systems. The selection system is used primarily on tolerant hardwoods such as Sugar Maple or American Beech and the uniform shelterwood system is usually used on upland tolerant conifers such as White Pine. In these systems individual trees are selected for harvesting, thus maintaining a continuous forest cover which encourages optimum regeneration. The third silvicultural system, clear cutting, is applied in patches to create openings for the establishment of (shade) intolerant species, such as White Birch and Trembling Aspen, which require an abundance of space and sunlight to regenerate."
I won't say the logging is perfect, but it's done to a pretty high and well thought out standard.
"logging is prohibited in July and August within 1.6 kilometres of a canoe route, including lakes, or within 30 metres of a public access road or recreation site. No logging can occur within 60 metres of campsites, portages, hiking and ski trails, and only modified partial cutting within 120 metres of all these recreational features.Ontario’s new Endangered Species Act presents an entirely new set of guidelines as to when logging can occur. For example, species at risk restrictions limit logging in many areas between October and April. There are a host of species-specific harvest and road construction restrictions, including timing and harvest modifications for wildlife such as hawk nests, wolves, moose and trout. There is also concern with certain species of turtles and the need to preserve their habitat, as they are long lived and don’t reproduce quickly."
