The lecturer points several problems with the salvage logging to dispute the author's claim. Actually, in the longer turn, salvage logging brings about more negative effects.

First, the lecturer states that cleaning up the dead trees does not create the right condition for the recovery of the forest because the decomposition of dead trees can enrich the soil with the nutrients essential for fresh growth. However, the author of the reading passage maintains that salvage logging can remove dead trees so as to help forest areas' recovery from the catastrophe.

Secondly, the lecturer refutes the point in the passage that decaying wood provides favorable habitat for the so-called harmful insects spruce bark beetle. She argues that it has lived in the forest for more than a hundred years without causing any critical damage. Furthermore, due to the fact that rotting wood can increase the insect population, it can certainly be exploited by those birds and other insects which do good to help flourish the forest.

Finally, although the author of the passage praises the economic benefits of salvage logging, the lecturer states that the economic value is finite and lasts short. Owing to the severe condition, helicopters and other expensive methods have to be employed to reuse those damaged trees. What's more, extra costs are required to train an outsider with specific knowledge, and thus the jobs created for local residents are temporary. Therefore, the economic advantages are greatly undermined.
