Report on LIBS’ Participation in Historic Research Conference

By Margaret Conover and Sue Avery
Long Island Botanical Society Members

We recently had the
opportunity to attend the
New England Botanical
Club’s 120th Anniversary
Research Conference as official
representatives of the Long
Island Botanical Society, and we
wanted to share our experience
with LIBS members.

The conference, held from
June 5-7, 2015 on the
Smith College Campus in
Northampton, Massachusetts,
was attended by about 155
botanists representing many of
the 31 invited botanical organizations. The weekend included
a networking reception, 21 talks and 16 posters on original
botanical research, a selection of field trips, and a roundtable
discussion on ensuring the future of botanical organizations.
A more complete description of the conference can be found
on the New England Botanical Club website: http://www.
rhodora.org/ conference20 15 / .

We arrived early Friday afternoon in order to visit the
herbarium and greenhouses of the University of Massachusetts
in nearby Amherst. Margaret was happy to verify that after
35 years, many of the plants she collected in Australia and
Malaysia have survived in cultivation there, although none of
her botany professors persist.

At the Friday evening reception, held in the Smith College
Greenhouses, we met up with Joanne Schlegel of the Niagara
Frontier Botanical Society. Some LIBS members will
remember Joanne from LIBS’ anniversary field trip to Florida
in 2011, and will be happy to learn that she will also join
our anniversary field trip next year. Following the reception
and houseplant give-away, we enjoyed a dining adventure with
some new Canadian friends from the North American Native
Plant Society (www.nanps.org) .

On Saturday there was a
packed program of talks on a
wide range of topics covering
regional floras, vascular plant
and fungal ecology, plant
adaptations to stress and
climate change, herbarium
collections and paleobotany.
Abstracts and videos of oral
presentations are available on
the conference website http://
tinyurl.com/ o47vb4g . Jesse
Bellemare (Smith College)
spoke on the naturalization
of Magnolia tripetala in the
context of climate change,
including fieldwork conducted on Long Island. Emily Marsh
(a student at Lyndon State College, VT) spoke on the impact
of invasive honeysuckle removal on black-legged tick density
in an exurban residential setting. LIBS member Richard Stalter
presented results of his and Eric Lamont’s survey of the vascular
plant diversity of the Monomoy Islands, Massachusetts.
Barbara Thiers (NYBG) spoke about the digitization of
the New York Botanical Garden Herbarium. David Werier
(LIBS member) raised our awareness and knowledge about a
highly invasive grass Brachypodium sylvaticum. James Mickley
(UConn — formerly Stony Brook) presented a poster on flower
development in Phlox species. C. John Burk (Smith College)
reported on a study comparing marsh floras from the River Elbe
with those of the Connecticut River along the freshwater-to
-saltwater gradient. Perhaps the most extraordinary presentation
was on the first North American record of a particular species
of Laboulbeniales, an ectoparasitic fungus on the American
cockroach, by Danny Haelewaters (Harvard).

LIBS was among several botanical societies that exhibited
at the poster session. We also distributed back issues of the
newsletter, which was well received. Our poster (Fig. 1)
highlights LIBS’ history and accomplishments, and although

LIBS Volunteers Needed: Save The Orchids. Since 1996, LIBS has been
partnering with Quogue Wildlife Refuge and other groups to manage
populations of white- fringed orchid ( Platanthera blephariglottis) , rose
pogonia {Pogonia ophioglossoides ), and associated marsh species including
carnivorous plants. This year, LIBS will host two trips to the refuge. The
first trip will occur when the white-fringed orchid blooms (end of July or
early Aug 2015). The second trip will occur sometime after the first frost,
perhaps in December, and will involve work clearing woody vegetation from
the marsh. If you are interested in volunteering to help save the orchids
please contact Eric Lamont (elamont@optonline.net) .

Sold Out. In 2010, LIBS and the Torrey Botanical Society published “ Tidal
Marshes of Long Island, New York ” edited by LIBS member John Potente.
The last copy (of 550 originally printed) was officially sold in May 2015.
Both societies are pleased with all aspects of this collaboration.

LIBS Speakers’ Registry

A registry of LIBS members willing to present a talk or lead a field
trip for garden clubs, libraries, and other groups is posted on our

Members who wish to participate should contact
Donald House at libsweb@vahoo.com .

Eric Lamont reports on the condition of the last known colony of Platanthera
ciliaris (yellow fringed orchid) in New York State. The population, along
Barnes Hole Road in East Hampton Township, is down to about a half
dozen individuals with one flowering in 2014.

Invasive Species Awareness Week is July 12-18 - Steve Young, Coordinator
of Long Island Invasive Species Management Area (LIISMA) urges us to
consider volunteer opportunities posted at http://www.liisma.org

Chuck O’Neill reports that in the past two years, the invasive species
management structure envisioned by the New York State Invasive Species
Task Force in 2005 has been fully realized. More information may be found
at http://www.nyis.info/

John Turner reports on progress toward permanent protection of Plum
Island. Congressman Zeldin has followed in Tim Bishop’s footsteps and has
introduced federal legislation to stop the sale of Plum Island to a private
bidder. There is more information about this at the Preserve Plum Island
Coalition’s website http://preserveplumisland.org/

we created it especially for this conference, we will certainly
exhibit it at various Long Island events. The content of the
poster is printed here, in abridged form, on pages 21 and
22 and can be reprinted and distributed as a membership
recruitment flyer.

Plant societies from throughout the Northeast were represented
at the Sunday morning roundtable, which was held at Smith
Colleges MacLeish Field Station. Fourteen participants
represented these ten organizations: Botanical Society of
America, Connecticut Botanical Society, Finger Lakes Native
Plant Society, Long Island Botanical Society, New England
Botanical Club, New England Wildflower Society, New York
Flora Association, Southern Appalachian Botanical Society,
Torrey Botanical Society, and the Vermont Botanical and
Bird Club. The main focus of discussion was on networking
and collaboration to ensure the survival of plant societies and
how they can play a role in nurturing young plant scientists.
We learned that we share many of the same challenges and
opportunities and agreed that we would try to meet together
again, perhaps at the 2016 Northeast Natural History
Conference.

striking example of a shelf
mushroom ( Ganoderma

Haelewaters who is the
mycologist who reported on
the cockroach ectoparasite.

The botanical foray that followed (Fig. 2) took us on a trail
through the 240-acre property attached to the field station.
We saw a striking example of black birch succession following
eastern hemlock dieback, and Michelle Jackson (a student at
Smith) showed us her field study work, which was the subject
of her talk on the decline of the hemlock- associated liverwort,
Bazzania trilobata.

On 17 June 2015, a meeting of
the North Fork Preserve (NFP)
Suffolk County Park Advisory
Committee was convened.
The meeting was held at the
Riverhead office of Suffolk
County Fegislator A1 Krupski.
Kevin Jennings, biologist for NYS
Department of Environmental
Conservation (DEC), and Eric
Lamont, president of LIBS,
were the invited speakers and
they presented a map showing
the recently (2013 and 2014)
mapped freshwater wetlands in
the park.

North Fork Preserve County
Park is located in the hamlet
of Northville in the Township
of Riverhead. Over the past
two years, DEC has funded the
mapping of extensive wetlands
at NFP, and additional wetlands
in the nearby vicinity (on the

Figure 1. “Paddleboat Pond” at North Fork Preserve County Park.
Suffolk County plans to develop this pond for active recreational use
including paddle boats. The extensive blanket of lush green plants
covering much of the pond bottom is a native bur-reed ( Sparganium
sp.). A 2014 LIBS field trip to the pond revealed it was bone dry on
October 18 th and vegetated with a rich diversity of sedges, rushes, and
flowering herbs including wool-grass ( Scirpuscyperinus ), dense stands
of spike-rush ( Eleocharis spp.), several species of Carex, Canada rush
(Juncus canadensis), soft rush ( Juncus effusus), bur-reed, and water-
primrose ( Ludwigia palustris), among other species. Approximate size
of the pond is 4.5 acres. [Photo by E. Lamont, June 20, 2015.]

Map) also will be mapped if
identified. Kevin explained that
the vast majority of wetlands
at NFP had not been mapped
when the DEC last inventoried
the area in 1993, but the
regulatory process is now “in
progress” for these wetlands.

Eric spoke of Long Swamp
which flows through more than
20 acres of the southernmost
portion of NFP, and explained
it has been locally known
by that name for more than
a century. Eric referred to
accounts of Long Swamp from
Roy Latham’s unpublished
journal. The headwaters of
Long Swamp lie just to the
east of NFP on the north side
of Sound Avenue. Water flows
from east to west and increases
in volume as more and more
water enters the swamp from
streams flowing down from the

Harbor Hill Moraine. Currently, Long Swamp is not officially
regulated by the DEC and Kevin reminded the committee
that the process takes time. Eric also presented the results
of the 2013 study of NFP’s rare ecological communities by
ecologist Greg Edinger of NY Natural Heritage Program (see
LIBS Newsletter (2014), vol. 24, p. 10).

Nick Gibbons, Environmental Analyst for Suffolk County
Department of Parks, Recreation and Conservation, stated
that because the NFP wetlands are not currently regulated by
the DEC the County is proceeding with plans to develop Long
Swamp into parking areas, picnic areas, and activity fields, and
other wetlands will be developed into playgrounds, basketball
and tennis courts, and an interactive spray park. One large
pond in the southeastern portion of the park (Fig. 1) will be
developed for paddle boats and another to the southwest will
have a fishing platform constructed on its shoreline.

12 months and other years they are dry for 12 months. Some
years the ponds are full in the spring and dry in summer;
other years they are dry in spring and full in summer. Many
ecologists now use the term “intermittent pond” rather than
“vernal pond” when classifying this ecosystem. Historically,
Long Swamp has periodically overflowed and flooded
surrounding land and roadways (Fig. 2).

Representatives from several other environmental groups
attended the meeting, including Eastern Long Island
Audubon Society, Group for the East End, and North Fork
Environmental Council. John Turner, co-chair of the LIBS
Conservation Committee, suggested to the NFP Advisory
Committee that the County first conduct a comprehensive
biological/ecological inventory, along the lines of what is now
occurring at Plum Island, prior to any decisions regarding the
various elements of an active park. Mary Laura Lamont, chair
of the LIBS Education Committee, asked if the County could
legally fill in Long Swamp and other freshwater wetlands. Nick

Gibbons replied “yes”
because the wetlands
are not currently
regulated by the DEC.
Byron Young, president
of Eastern Long Island
Audubon Society, asked
how long it would take
the County to start
implementing these
development plans and
the reply was four to
five years.

Suffolk County
officials appear unaware
that these ponds
(“Paddleboat Pond” in
particular) periodically
dry up and the mucky
substrate becomes
blanketed with a
dense cover of native
vegetation (Fig. 1).
Some years the ponds
are filled with water for

Figure 2. Northville’s Long Swamp went on a rampage in January, 1979, flooding the
road near Vernon Wells’ house. After a similar flood in March, 1912, the Riverhead News
reported, “It has been many years since the swamp has had such an outing.” [Image

ELAINE JACOBSON

While re-reading
the Summer 2011
Newsletter which
featured the LIBS
25th Anniversary
Trip to Florida
(March 30-April 8,
2011), I was struck
by how much Elaine
Jacobson added to the enjoyment of our trip. Elaine, my friend
and neighbor in Sanibel Island, Florida was the “Energizer
Bunny” who saw to it that every detail was attended to and
everybody was happy. A peak moment of the trip was when
Elaine discovered the long-sought rare mint, Ashe’s calamint,
(Calamintha ashei) all by herself behind the Holiday Inn at
Sebring. She was so thrilled that she burst into tears! We later
learned that it was her birthday as well! Not long ago she told
me that the LIBS trip was the highlight of her life.

Elaine and I met on a “Weeds N Seeds” walk a good many
years ago. She dove headfirst into botany - what people
couldn’t tell her, she researched on the web and learned from
her microscope. She led nature walks, kept lists, did inventories
and ran the eight Audubon lectures every year on Sanibel.
These were enthusiastically attended by as many as 300 people
every Thursday night in January and February and the speakers
were preceded by delightful slide shows put together by her
husband Jake.

Last February 17th she was suddenly diagnosed with cancer of
the lung, brain and liver. Despite her illness throughout this
winter, she put together the Audubon program for next year.
In late April, she and Jake were able to drive up to their home
in New Hampshire. After a valiant struggle against enormous
odds, Elaine died in a hospital in Peterborough, N.H. last
Friday July 10th.

Long Island is one of the most densely populated regions
in the United States. As of the United States 2010 Census,
the total population of all four counties of Long Island was
7,568,304. Western Long Island includes two boroughs of
New York City. The two eastern counties of Long Island
are home to over 2.8 million residents; population density
averages over 2,000 residents per square mile. If it were a
U.S. state, Long Island would rank 13th in population and
first in population density.

Today, nearly two-thirds of Long Island’s land surface is
covered with buildings, pavement or other man-made
structures. It is virtually guaranteed that Long Island will not
meet its goal to preserve 10% of the Island’s land mass as
open space and farmland by 2016.

Meetings

LIBS holds monthly evening meetings eight times a year,
alternating between locations in the two eastern Long Island
counties. Invited speakers have presented programs on a
variety of natural history topics such as “Novel Ecosystems” by
Marilyn Jordan, “An Ecologist Visits New Caledonia” by
Andy Greller, “Bat Pollination Studies in Costa Rica” by
Maria Brown, “Long Island Lichens: From Distant Past To
Uncertain Future” by James Lendemer, “Tropical American
Botany Overview” by Eric Morgan, “The Urban Oasis:

Long Island is formed largely of two spines of
glacial moraine, with a large, sandy outwash plain
beyond. These moraines consist of gravel and loose
rock left behind during the two most recent pulses
of Wisconsin glaciation. Long Island ecosystems
include beaches, salt marshes, oak forests and
pine barrens as well as remnants of two globally
rare ecosystems: a prairie grassland known as the
Hempstead Plains and an area of dwarf pitch pines
within the pine barrens known locally as the Dwarf
Pine Plains.

Publications

Tidal Marshes of Long Island, New York

In cooperation with the Torrey Botanical Society, LIBS
published Memoirs of the Torrey Botanical Society Volume
26: Tidal Marshes of Long Island, New York. This publication
presents the most current research on the tidal marshes of
Long Island, New York, by the region’s leading scientists and
environmental law experts

Atlas of the Vascular Plants of Long Island, New York

The society’s soon-to-be-published Atlas of the Vascular Plants
of Long Island, New York, presently under review, consists of
distribution maps for vascular plant species occurring on Long
Island, including native and naturalized non-native species.

Sample illustration of the Atlas.

Conservation

The Long Island Botanical Society is not an environmental
activist organization, but many times over the years it has
partnered with other groups and taken a position advocating
for the conservation and preservation of specific properties of
botanical interest. For example,

• Raised awareness of the rare maritime American beech
sandhills, threatened with development (1999).

• Supported the permanent protection of the Edgewood-Oak
Brush Plains State Preserve and currently working to increase it
by 50 acres (2008 and ongoing).

• Supported grant request and provided volunteers for
eradication of hardy kiwi from Coffin Woods Preserve (2013).

• Helped DEC to document a rare ecological community at
North Fork Preserve, Riverhead (2013).

• Pursuing a conservation easement to preserve a 13-acre Islip
industrial site where Pyxidanthera barbulata and several other
rare species are found (ongoing).

• Working with Suffolk County to preserve sensitive parcels
around Hauppauge Springs (onging).

Newsletter

The Long Island Botanical Society Newsletter has been
published for the last 25 years and features articles written by
society members and others, a list of recent plant sightings, lists
of upcoming programs and field trips, and announcements of
society activities. Back issues of the newsletter are archived at

The New York Botanical Garden Announces
Native Plants Summit:

CURRENT STATUS, CONSERVATION, AND
OUTLOOK FOR PLANTS OF THE NORTHEAST
Friday, September 18, 2015; 9 a.m.-3 p.m. Ross Hall

The northeastern U.S. hosts a rich diversity of native
plants, many of which play essential roles for humans
and the environment. Alarmingly, a significant number
of these species are experiencing a precipitous decline.
Many natives are imperiled as a result (New York State
considers one-quarter of its native plant species to be
of conservation concern). Despite these figures, no
comprehensive or integrated program exists to study
trends in the status of native plants across the region.
Through a series of compelling presentations, followed by
a panel discussion, this summit will address our dearth
of knowledge by bringing together experts and interested
members of the public to present and discuss the state of
the areas plant species, plot the best course forward, and
highlight ways in which everyone can make a difference
for native plants in the Northeast. NOTE: LIBS member
David Werier is one of seven invited speakers.

September 8, 2015* Tuesday, 7:30 PM

Daniel Atha: “Smartweeds of New York: Taxonomy
and Identification.” With twenty species in the
northeastern United States, the genus Persicaria ranks
among the top twenty-five largest genera of flowering
plants, just behind sunflowers and hawthorns. Many
are native wetland species and are an important
food source for waterfowl. Others such as the East
Asian mile-a-minute vine can inflict great ecological
and economic harm. Daniel is a research associate
at The New York Botanical Garden and has done
extensive field work throughout the United States
and abroad. He co-authored the Persicaria treatment
for the Intermountain Flora and is currently writing
the Polygonaceae treatment for the revision of the
Gleason and Cronquist Manual.

Location: Bill Paterson Nature Center,
Muttontown Preserve, East Norwich

October 13, 2015* Tuesday, 7:30 PM

Emily Rollinson: “Biodiversity and Biological In-
vasions in Stream-side Plant Communities.” Stream-
side (or riparian) plant communities are often quite
diverse, but atthe same time, may be highly susceptible
to invasive species. This talk will describe ongoing
research in small tributaries of the Hudson River in
upstate NY, investigating the factors that underlie
both diversity and species invasions in riparian plant
communities. Emily is a Ph.D. candidate in the
Department of Ecology and Evolution at Stony Brook
University. Her research focuses on plant community
ecology, ecological disturbances, and biological
invasions.

Location: Earth and Space Science Building,
