If you don't see the applet below, it's time to upgrade your browser!
While the below simulation is not entirely accurate, it will give you some idea how the re-entry and cutting rates affect a forest. We are currently working on a more accurate simulation.
Example: The "win/win" solution voted into place for Santa Cruz county on June 6th 1998 allows 50% cutting of trees > 18 inches diameter at breast height, and 40% of trees < 18 inches diameter, with a 10 year re-entry period.
The below applet doesn't take into account the size class restrictions which were part of the "win/win" package.
First, try pressing "calculate results" to see what happens when there is no harvesting. Then, enter these figures into the "amount harvested" box to see what percent is left after 100 years.
