Russian Olives may help some species
According to study done in Southern Idaho that
was published this spring in Northwest Naturalist,
Russian Olive tree expansion may have benefitted some
species in the region.
The 14 most common species of the 28 recorded
in 2000 and 2005 across Southern Idaho during
Christmas bird counts were found in both years, and
most common species were recorded with similar
frequencies between years, according to the paper’s
author, Dan Taylor, a former Pocatello resident.
Thirteen bird species were observed foraging on
Russian Olive fruits. Increases in recent decades in both
areas occupied by Russian Olive and in counts of Yellow-
rumped Warblers and American Robins on Christmas
Bird Counts suggest that there may be a relationship
between Russian Olive expansion and abundance of
these species, Taylor said.
Upper Snake River Basin Watershed areas in
Southeast Idaho that were surveyed for the study
included Batise Springs, Fort Hall Bottoms, Springfield
Ponds and American Falls Dam, spots frequented by

Russian Olive in Southern Idaho.”
