Nature mops up
In harbors, waterfronts and shorelines around the world, sediments that
have been contaminated by even small amounts of oil, chemicals, or other
polluting substances could pose a health risk to both nature's fragile
estuarine ecosystems, as well as to the rest of us. Sometimes this
contamination is not even evident without testing. Traditionally, the
solution has been to dredge (and place contaminated sediment in upland
disposal areas where it must be further managed to prevent exposure to
yet other ecological species), and presumably bring the quayside back to
its pristine character. For many years, the Navy has looked at the best
way to manage this contamination without disrupting an ecosystem that is
fragile, but still functional.
Now, scientists funded by the Office of Naval Research have found there
is evidence of a natural process called intrinsic bioremediation,
whereby the resident bio-organisms in contaminated estuarine sediments
can degrade or become a net sink for hydrocarbons and other organic
pollutants, and thus may function as a filter within the ecosystem. In
other words, the natural bacteria in the sediment - adapted by years of
exposure to the problem - are doing a clean-up on their own. The natural
bacteria metabolize (i.e. eat) the offending hydrocarbon pollutant (gas,
oil, etc). Removal of the sediments that have microbiologically adapted
to do this clean-up may actually increase the problem. If the dredging
is done in estuaries with other industrial discharges occurring it
doesn't take long for the system to again reach a contaminated state.
"What could happen," says Mike Montgomery of the Naval Research
Laboratory, "is that we'd spend millions of taxpayer dollars to dredge
the sediments, and end up doing more harm than good. We could create an
even worse buildup of oil by removing the very elements that are solving
the problem for us."
###
Research on this phenomenon funded by ONR and others continues in the
Charleston Harbor Estuary (site of the former Charleston Navy Yard),
around the Philadelphia Naval Complex Reserve Basin, San Diego Bay, and
at other locations around the country. The strategy now is to learn how
to identify sediments that may be undergoing intrinsic bioremediation,
so that site clean-up programs can be planned accordingly.

How to keep invasive plants out of forest fragments
Fragmented habitat is vulnerable partly because it has more edges, which
are susceptible to invasion by non-native species. While the obvious
solution of minimizing the amount of edge is not always feasible, there
may be another effective approach: intact edges can help keep seeds out
of the forest interior, according to new research in the February issue
of Conservation Biology.
"Our work addresses the impact of forest fragmentation at the
'neighborhood' scale -- what happens when developers put up a new strip
mall or housing complex. The development of our landscapes continually
fragments forests and [that] should be considered when thinking about
the distribution and degree of aggregation of homes," says Mary
Cadenasso of the Institute for Ecosystem Studies in Milbrook, New York,
who did this work with Steward Pickett of the same institution.
Cadenasso and Pickett measured how many seeds blew from an old field
into an adjacent deciduous forest patch, a common type of edge in New
England. The researchers studied seeds that are dispersed by the wind
because many invasive plants have wind-borne seeds. To see how the
forest edge's structure affected seed invasion, the researchers compared
two types of edges: intact and thinned. They created 130 feet of thinned
edge by removing all trees, shrubs and branches that were less than half
the height of the forest canopy; this thinning extended 65 feet into the
forest patch. The resulting thinned edge resembled that created by
logging or a large blowdown.
The researchers found that four times as many wind-borne seeds crossed
the thinned edge than the intact edge. They also found that seeds
crossing the thinned edge penetrated 2.5 times deeper into the forest
(145 feet into the "thinned edge" forest vs. 55 feet across the "intact
edge" forest).
To help protect forest fragments from invasive weeds, Cadenasso and
Pickett recommend "sealing" the edge by planting it densely with native
shrubs, vines and understory trees, as well as removing non-native
plants from the edge.

Dear Lisa:
More popular press articles about his butterfly work include the April 2000
issue of Atlantic Monthly with a feature title of "Nabokov's Butterflies,
pages 51-75. Also, the March 29, 1999 issue of the New Yorker has a
two-page spread. Page 339 in Kurt Johnson and Steve Coates book "Nabokov's
Blues" refers to them as "a certain significant group of Latin American
Blue butterflies". Apparently he named five new genera of blues. The common
name for Lycacides idas sublivens, a subspecies he named in 1949, was
"Nabokov's Blue", but Johnson and Coates say "it has been known more
recently as the Dark Blue" (pg. 330). This doesn't answer your question
directly, but may provide some related hunting grounds.
Best regards,

Subject: volunteers sought for research in S. NV
I am seeking volunteers to assist me with my dissertation field research
in southern Nevada from mid-March to mid-May 2001. The purpose of the
research is to investigate the determinants of phainopepla abundance and
breeding success (phainopeplas are a small frugivorous bird of
management concern in the area). Field work will involve measuring
phainopepla densities, finding and monitoring nests, and evaluating
resource abundance in mesquite and acacia woodlands in a wide variety of
sites in southern Nevada.
Volunteers should have either extensive birding experience or a B.S. in
Biology or Environmental Sciences. No vehicle is required, but
possession of a valid driver=92s license is preferred. I am especially
seeking volunteers who can commit to a regular schedule of assistance
(e.g. 5 days a week, or every weekend), but may also be able to
incorporate volunteers who wish to assist me occasionally.
If you are interested, please send me, Cali Crampton, a letter detailing
your experience and interest in the project and a 1-2 page resume by
email or regular mail.

Subject: canoe & kayak trails/preserving land
A couple of questions regarding conservation & preservation
efforts:
(1) There is a huge tract of land - 60,000 acres that is
completely undeveloped in the middle of a sea of urban
development (N. Houston) and I'm trying to garner support for
getting it preserved. It would be ideal for a National Park as
its 10-minutes from the Houston Intercontinental Airport. If any
of you have insight into the Land and Water Conservation Fund and
suggestions for this process, I'd be very appreciative! This
region lies between the San Jac River and Spring Creek, contains
some of the highest quality wetlands remaining in this region
(all SE. TX) with thick palmetto thickets and bottomland hardwood
forest. 70% of US bottomland hardwood forests are gone.
(2) Does anyone have experience setting up a canoe & kayak trail
in their region?
I am in need of info on the logistics -- costs of signage, how
you promoted it, costs of informational material/maps, etc.
I'm also interested in any research or anecdotes showing whether
these water trails increase local awareness of the aquatic
habitats, and/or increase preservation efforts along the route.
I'm asking because my new nonprofit group, San Jacinto
Conservation Coalition (www.sanjacinto.cc) has just raised funds
from a River Bottom Festival and Canoe Marathon and we plan to
create a C&K trail along the San Jacinto River.
Thanks!

GLOBAL CHANGE OPEN SCIENCE CONFERENCE:
SESSION ON MOUNTAIN REGIONS
*************************************
(Amsterdam, 10-13 July 2001)
I would like to draw your attention to the Open Science Conference
(OSC) "Challenges of a Changing Earth", which will take place from
10-13 July 2001 in Amsterdam. This conference is a joint effort of the
three Global Environmental Programmes IGBP (International
Geosphere-Biosphere Programme), IHDP (International Human Dimensions
Programme) and WCRP (World Climate Research Programme).
I am happy to inform you that we will organize a session on "Global
Change and Mountain Regions" at the OSC, which will be chaired by
Dennis Lettenmaier, P.S. Ramakrishnan and myself. The Mountains session
will be held on 12 July from 13:30 - 16:00. I am attaching an rtf file
with a short description of this
session.
An important element of the OSC will be poster clusters, i.e. sets of
posters dedicated to particular aspects of Global Change. We would very
much like to have a poster cluster to accompany the Mountains session,
and we now are soliciting Abstracts for posters that would contribute
to the cluster on Global Change and Mountain Regions. Selected posters
may be presented as oral contributions during the session itself.
For further details of the conference and the sessions, please check
the conference homepage at http://www.sciconf.igbp.kva.se.
In case you are interested in submitting a poster abstract, please do
so
via the web page given above; please be sure to send a copy of your
abstract to Sabine Luetkemeier (mailto:luetkemeier@pik-potsdam.de), who
serves as the contact point for this session and the associated poster
cluster.
Also, I would be grateful if you could forward this announcement to
people who may be interested in this topic.
Many thanks for your attention.
Best wishes,
Harald Bugmann

Subject: Question: tagging trees
My question is on potential collateral harm from
nailing in survey tags on trees. I did a walnut
survey a couple of years ago in which the employer (a
university) insisted on nailing in the ID tags on each
tree. Now I've got another survey to do and am
wondering whether it is better/safer to simply tie the
tags on (though not as permanent) or to attach them
with nails. Is anyone aware of adverse affects of
doing the latter?
Thanks.

Subject: on tagging trees - an opinion summary
Folks:
I want to thank all the great responses to my question
on nailing trees. The consensus by far is that
rounded aluminum nails 1) do little or no harm to
adult trees; 2) should be nailed in at an angle (upper
part on tree, lower at hammer end) to prevent water
from running into the nail hole and causing infection,
which was a concern I had; 3) are a pain in the rear
to nail into hardwoods such as walnut and oak; and 4)
are friendlier to chainsaws than are steel nails in
the event trees are cut down.
A couple folks pointed out that wire tags may be
preferred for short term projects (less than 1 year)
but that if used around trunks or branches and left
will cause girdling (and I have seen that plenty at
botanic gardens and nature preserves).
Another person suggested leaving some of the nail
sticking out of the tree in the event one wishes to
remove the tags after a longer period of time.
Lastly, and somewhat new to me, is the use of screws
rather than nails. In that person's experience,
loosening the screws allow the tree to grow while
maintaining the tag over the long term.
There were, in addition, quite a few negative comments
regarding the efficacy of tie-tags.
Thanks all....and I guess I've got some nailing to do!
Stephen

From: Wayne Tyson <landrest@UTM.NET>
Subject: Re: Culture, a word rooted in "cut"?
Forum and Vicente:
Vicente is quite right about the etymology of culture coming from the Latin
"cultus," but the Latin root means "to cut." That's part of forestry, but
not the be-all and end-all of it. Just leave a few snags for the
woodpeckers, Vicente and cut in peace--I still go to the lumber yard and
use paper. It's a matter of degree, a matter of individual judgment and
decision, and a matter of direction. I hope that in forestry, cutting does
not undermine forest productivity, such as occurs when clearcuts cause
root-death and decay which removes the reinforcement and soil permeability
influences (not to mention rainfall interception, stemflow "metering" and
infiltration capacity) conferred by standing timber. Woodsman, spare
enough trees to ensure that the ecosystem's capacity for producing a
sustainable "cut" is not undercut by overcut.
Best,
WT
PS: The suffix "scape" in landscape does come from the Old Dutch,
"skep." No doubt "skep" comes from "cultus" too, but I haven't confirmed
that--yet. Vicente, I do agree that "caring" is at least a long-held
cultural interpretation (whether it is valid etymologically or not is not
important to me) of culture, but I submit that it is more rooted in
"caring" for the purpose of "getting" a payoff from the "care." Some might
say that this is semantic hair-splitting, but I think all honest scholars
will recognize that this issue is central to the issue of living in an
ecological system and exploiting it to the detriment of the system's
productivity. No matter how you "cut" it, "caring" by humans has resulted
in ecosystem degradation, no matter how euphemistically one manipulates the
language used to communicate or mislead. Now--caring in the sense of
arresting the trend of cultures to degrade ecosystems is another
matter. On that I will not split semantic hairs--and I hope that's what
you mean. If not, I hope you will extend and clarify your remarks. A
caring culture--provided that is not an oxymoron, I belive you have
summarized my point.
