Replanting one type of tree is not enough to stop clearcutting harm, study findsPlanting trees to replace clear-cut forests is not good enough to protect the ecosystem, according to a new study focused on forests in the Maritimes.
Matt Betts, a professor of forest ecology at Oregon State University, is studying the decline of bird species caused by deforestation in the Maritimes and the replacement of diverse Acadian forests with one type of tree.
The study, which was published Thursday in Nature, Ecology and Evolution, shows some species have seen a population decline of up to 70 per cent since 1985. More common species have seen a decline of 50 per cent.
"At the very least, we need to change some of our core forestry practices, focus more on maintaining those those nice, colorful Acadian forest tree species we have," he told Shift New Brunswick.
The species most affected is a little migrant songbird with a bright orange face called the Blackburnian warbler, which has seen a 70 per cent decline.
