Jefferson Park and Mt. Jefferson |
Sometimes you
have to wonder about scientific studies and the resources spent to research
things that seem to be obvious. You also have to wonder how some
conclusions are ascertained. Here is one of those instances.
According to
a study by Oregon State University, funded by the Pacific Northwest Research
Station and published in Landscape
Ecology, high mountain meadows in the Pacific Northwest are declining rapidly due to climate change.
An article written by Phys.org says the study cites factors such as reduced
snowpack and longer growing seasons as reasons for trees to encroach on meadows.

In a recent
analysis of Jefferson Park, a 333 acre subalpine meadow complex in at the base
of Mt. Jefferson, tree occupation rose from 8 percent in 1950 to 35 percent in
2007. The article, however, cites no comparative study that would actually
signal that trees are populating the meadow any faster than at any other time
in history. There is also no mention of any conclusive evidence in the article
that climate change has anything to do with more rapidly growing tree
populations in the meadow.

"We
worry a lot about the loss of old-growth forests, but have overlooked declines
in our meadows, which are also areas of conservation
concern," said Harold Zald, a research associate in the College of
Forestry at Oregon State University and lead author of this study.

Yes, old
growth forests eventually die and regenerate, just as meadows eventually become stands of
trees. This is eighth grade earth science. Lakes fill with sentiment and
eventually become meadows, which eventually fill in with trees and become a
forest.

You can have
all the conservation concerns in the world, but you don’t stop old growth
forests from dying and meadows from becoming forests.
