Subject: [ia-bird] Bird habitat destruction in the name Invasive species removal for Prairie and Oak Savannahs.
Hi everyone,

I have held off on writing this because I know it will not be accepted by
some but have in the past spoke with The Army Corp, Iowa DNR and the
Naturalist for Big Creek. All relating to the destruction of bird habitat
such as seen most recently at Lost Lake Trail - Ledges State Park at Cherry
Glenn a couple years ago. Big Creek State Park every year even to the point
of girdling, chemical spraying, then removing mature trees along with
invasives on as small as one acre plots to turn into prairie.
When I was young the Iowa DNR promoted the positive impact that "edges" had
on wildlife. Today it is all about prairie and oak savannah, nothing else.
I could go to Cherry Glenn and sit in one spot and see twenty species of
birds including Warblers, Tanagers and Cuckoos. After the area was
cleared of all undergrowth there has been none of these because the edges
are gone. The same way with the walking path at Lost Lake Trail -Ledges
which was a go to spot for me and others to see warblers in the Spring.
This year they were few and far between after a group that thought they
were doing the right thing cleared all the forest floor.
I think IOU should get involved with input on what works for birds but when
I was on the board told "Oh no, we can't get involved with that".
Many of you have been taught in college that it's all about prairie and Oak
Savannah but there has to be a reasonable acceptance that we are observing
negative changes in our parks with these methods.
I recently visited numerous parks such as Lacey-Keosaqua and you don't see
the Brush Hog destruction along roadways in the parks that lay there for
years as at Big Creek and Army Corp property. I hope they don't follow suit
at DNR directive.
When asked about large tree planting projects I'm told "We don't have funds
for that". Yet there is plenty of money for equipment to destroy habitat.
When asked if they were going to replant with native species to replace as
they call "low value" berry bearing bushes, "We don't have funds for that".
There's plenty of money for burning prairie which I don't have a problem
with but there has to be a return to tree planting and "Edges". I don't
understand how trees around the edges would negatively impact the prairie.
The North end of Bays Branch in Guthrie county once had a very large
woods/prairie area that once a Prairie Warbler was reported there. Now it's
nothing but stumps and very few birds.
IOU could have some input on this if the board would be willing to be
proactive and ask these organizations to consider the edges we need for
birds.

Sincerely,
Clayton Will
