Re Jennifer Seavey's BTPI discussion:

Yeow, she wasn't kidding. Here are the BBS trends for WA and OR:

State Period Trend n sig.
OR 1982-1991 -14.7 19 p<.01
OR 1966-1991 -3.2 21 p<.01
WA 1982-1991 +.7 21 none
WA 1966-1991 -3.5 23 p<.1

The trend is expressed as % annual change using a formula similar to that
for calculating compounding interest. n is the number of BBS routes from
which the trend was calculated. The authors warn against using data for
species where n<14. p is the significance of the trend, from testing the
hypothesis that the trend is actually 0. The source is an untitled,
unpublished report from Bruce Peterjohn for USFWS/NBS biologists.
