Studies show that the plantations that replace diverse forests are extremely fire-prone.
When there are wildfires in plantations, the percentage of trees killed is much higher than in older mixed species forests.

The slash that is left creates a greater wildfire danger.

As more forests are leveled by clearcutting in California, the
use of herbicides increases every year. In California 258,000 pounds
of chemical herbicides were used for forestry by 2006. Herbicides are
sprayed on clear cut areas to keep the native plant species from
regenerating and competing with the replanted single-species
plantations. This destroys diversity and the food sources for many
species of wildlife.
