Figuring the Loss of Trees
UC Davis Ag Econ Department has put together a set of crop loss calculators in Excel. They are generic, but also specific to lemon and avocado. If you have had damage from the recent fire, take a look at them. At this point it may be too early to actually know the extent of the damage, but keep these in mind for the future.
