[MAIPC] the economic cost of stormwater damage caused by invasive species

In order to justify invasive plant control funding to reduce the cost of
stormwater management, we especially need the contribution by stormwater
management experts. Who can provide us an estimate of the storm water
management costs along streams? In our region, Japanese Stiltgrass typically
covers 20% of the habitat. With this cost information we can estimate the
economic contribution of Japanese Stiltgrass to be ~ 20% of the expenditures
for storm water management along the steam since it doubles the amount of
storm water runoff. Follow up studies will be needed, of course, including
info about other invasive plants species that increase storm water runoff.
But at least this will be a start. Even costs for just one stream would be
helpful. Thanks so much.

Hi, Marc.
Eliza Cava, the Audubon Naturalist Society's Director of Conservation, was
wondering if there is a "position paper" or fact sheet on this topic.
Thanks,
Ken

Hi Ken,
Thanks for forwarding, this is very interesting. I think it meshes well with
stormwater partners network's promotion of green infrastructure, which
always should focus on (if not be limited to) native plants. I will say that
when I first saw your email I read it backwards-I thought you were saying we
should promote non-native invasive plants! In the back-and-forth email
traffic, have you seen any more formal write-ups or fact sheets we could
save in a sort of Stormwater Partners "library"?
Thanks,
Eliza

In case you haven't seen this. Maybe more funding for non-native invasive
plants should be promoted as an additional way to control stormwater.

I participated in a conference call on invasive species with one item on
the agenda to update the economic impact of invasive species. There are many
kinds of economic impact besides the cost of removing invasives. For
example, the economic cost of stormwater damage caused by invasive species.
Many studies have shown that Japanese Stiltgrass doubles the amount of
nitrogen and storm water released into the Chesapeake Bay. The primary
reason is that the tiny root system replaces the complex root system with a
variety of niches that are necessary to hold water and release it slowly.
This argument could be used in general for other non-native invasive species
replacing a complex of many native species with different root systems of
different depths etc. In our region the surface of Japanese Stiltgrass has
expanded typically to now cover over 20% of the habitat.
Does anyone have a cost update for the economic cost of stormwater damage
caused by invasive species. Thanks.

This would be a very helpful piece of information to have! I think of all
the efforts dealing with Fallopia and Impatiens infestations in riparian
areas, the impacts in watershed integrity are similar to that of increased
stormwater runoff - a simplified and degraded aquatic environment less
capable of performing historic ecological services or watershed functions.
I can't think of any investigations here in the Pacific Northwest that
looked at how these two stressors interact? Which is a gap that would be
worth filling given the strong investment in salmon habitat and wetland
restoration. In Metro Vancouver integrated stormwater plans are legally
mandated across the region for all watersheds, there is also a lot of effort
by municipalities to deal with invasive plants in those same watersheds. But
the two aren't necessarily dealt with in an interrelated way. Which they
should be given the projections for increased intensity for rainfall events
due to climate change coupled with ongoing development pressures..

On the other hand, Phragmites removes more nitrogen and metals than Spartina

Hi Marc,
Thanks for raising the question of impacts of invasive plants on storm
water. I'd be very interested to know of any data and publications that
might shed light on this issue.
I was also very interested to learn of the references regarding increased
nutrification as caused by invasive plants and earthworms. Do you have
copies of those papers that you can share?

Subject: Question about Invasives and Hydrology
Hi Marc,
I am writing you with a question about whether there are studies
that show how removing invasive plants in the understory correlates to
positive effects on water quality or macroinvertabrate habitat in streams.
You seem like the guy who could point me in that direction. We are hoping to
write a grant here at the middle patuxent environmental area to remove about
3 acres of invasive autumn olive, multiflora rose, barberry, amur
honeysuckle, bittersweet and do native replantings. But it's a grant that
should relate to positive effects on water quality somehow. Please let me
know if you have any ideas on how I could describe this for the grant due
October 31st.
Many Thanks,

Subject: your e-mail on Green is Good
Hi Marc,
There is still time to show people the vast unfolding disaster of Japanese
Stiltgrass around the Loch Raven Reservoir this season before it all goes
yellow - actually right now it is peaking or just beyond the peak growth.
You are absolutely right, there is no substitute for seeing a huge area in
person! Getting them on a site is crucial.
If a relationship through research could ever be demonstrated between
invasives taking over the reservoir and a degradation of the water supply
for over a million people, that would be great. That's the only thing that
is going to work as far as I can tell. If I've already asked you about
this, please forgive me - and could you send it again?
Thanks,
Laurie
