Yosemite National Park publishes a daily report, page 2 of the current edition (Monday, September 14, 2009) lists the damages caused by bear activity.
The year to date table:
# of Incidents Damage
Parking Lots 70 $43,582
Campgrounds 173 $ 7,129
Other Areas 166 $ 9,969
Backcountry 27 $ 2,106
Total 436 $62,786
You have to wonder how much of this damage is really caused by park visitors being sloppy with food storage.
It appears these figures are a dramatic improvement because the report states that in 1998, Yosemite bears “caused” over $600,000 in damage.
