Common Murre Population Monitoring in the Chiswell Islands, AK, 1989-2001
We censused the Chiswell Islands murre colonies three years after the last population counts were made using the same methods used during the 1998 restoration monitoring project. Counts were pooled with the 1998 estimate and earlier 1989-2002 U.S. Fish and WIldlife Service and 1991 Dames & Moore...

Results were similar to 1998: the average score was almost the same as our earlier estimate, which strengthened the previously discovered negative trend.
