Ecosystems that have been altered
by human activities can provide suitable habitat for native birds, according to
scientists in the United States and Australia.
In a study published in the
journal Ecosphere, the researchers concluded that while some native birds
are sensitive to novel ecosystems, others don't seem to mind.
The study results shouldn't be
interpreted that habitat restoration to historic conditions is futile and that
all novel ecosystems are acceptable, said lead author Pat Kennedy, a wildlife
biologist at Oregon State University. But they do show that habitat restoration
can be prioritized.
"Prior to our study, the
usefulness of novel ecosystems for native wildlife was a concept. Now we have
empirical support," said Kennedy, a professor in OSU's College of
Agricultural Sciences. "Our data suggest that controlling non-native
plants may not yield important benefits for some nesting birds, yet we are
spending a lot of time and money attempting to restore these ecosystems. We
need to start thinking more critically about restoration priorities."
