Reread the thread. I asked about the last 10 years; their response gave data over the last 30, but in the last 10 it's hovered between 100 and 125 (with lots of volatility). 2004 is, of course, more than 10 years ago.

By way of context: in the 30 year timespan covered by their document, almond acreage in California has more than tripled.
