ELA Roundtable
Saturday, December 1, 2007
9:00am – Noon
Bio-control in the Garden:
New Research and Techniques for Invasives Co-sponsors: Arnold Arboretum and the Ecological Landscape Association
Fee: $35 member, $40 nonmember
Co-presenters: Lisa Tewksbury, Manager, Biological Control Laboratories,
University of Rhode Island; Bruce Wenning, Land Stewardship Manager
for Land’s Sake, Inc.
Invasive species are here to stay and their numbers will only rise with
increasing globalization. But this doesn’t mean defeat for landscapers and
gardeners. What it does require is considering the dynamics of ecosystems
and developing methods for keeping aliens in check.
In this program on problem insects and weeds of New England, Lisa
Tewksbury, an entomologist and manager of the University of Rhode Is-land’s Biological Control Laboratories, will present a variety of bio-control
techniques, including her lab’s current work with lily leaf beetle, birch leaf
miner, Cyprus spurge, purple loosestrife, common reed, swallow-wort, as
well as hemlock woolly adelgid. She’ll update us on success stories and
challenges and when we can expect to see the results of some of the
newly introduced “ghters.”
Bruce Wenning will present various methods used and the successes
and failures he experienced in removing invasive plants at an urban
wildlife sanctuary.

How many times in the past few years
have you received a catalog from a
company that you had previously done
business with but no longer require their
services? Catalog Choice is a free service
that lets you decline paper catalogs youno longer wish to receive. It enables
you to reduce the amount of unsolicited
mail in your mailbox, while helping to
preserve the environment. Just enter your
name and e-mail address and then the
company “Catalog Choice” sends you an
activation link to click on in an e-mail
and when you receive it you supply your
mailing address and click on what cata-
logs you no longer wish to receive. It’s

EPA Pushes Procurement of Materials
from Recovered Waste
Release date: 09/10/2007
Contact Information: Roxanne Smith,
(202) 564-4355 / smith.roxanne@epa.gov.
(Washington, D.C. – Monday, Septem-
ber 10, 2007) The U.S. EnvironmentalProtection Agency is revising the list of
items designated in the Comprehensive
Procurement Guidelines’ landscaping
products category to promote the use of
materials recovered from solid waste. EPA
is expanding the description of “compost”
from yard trimmings and food waste to
include compost from biosolids and ma-
nure, but does not limit the designation
to specic types of organic materials. In
addition, EPA has added fertilizer made
from recovered materials as a designated
landscaping item.
The Resource Conservation and Recovery
Act requires procurement ofcials to buy
products containing recovered materi-
als when the agencies spend more than
$10,000 a year on that item. Procuring
agencies are federal, state, and local
agencies, and their contractors that use
appropriated federal funds.
For example, if a county agency spends
more than $10,000 a year on an EPA-
designated item and part of that money
is from appropriated federal funds, then
the agency must purchase that item made

Massachusetts Arborists AssociationCelebrates the 50th Anniversary of
the Massachusetts CertifedArborist (MCA) Program
The Massachusetts Arborists Association
(MAA) announces the 50th anniversary
of the Massachusetts Certied Arborist
(MCA) program. The oldest state-wide
voluntary certication program in the na-
tion, the MCA has become the symbol
of professionalism in arboriculture in the
Commonwealth of Massachusetts.
The MAA will celebrate a half century of the MCA program at its November 27 th
Annual Meeting and at New England
Grows in February 2008. The rst MCA
examination was administered on Febru-
ary 13, 1958 at the Waltham Field Station
of the University of Massachusetts. By
1960, a list of 25 MCA-certied arborists
was published. Since then, the ranks of
Massachusetts tree care professionals car-
rying the MCA designation have swelled
to more than 800.

youth with training and exposure to the
green industry along with the acquisition
of their GED. The focus will be on land-

can use to enter the work force or higher
education. YouthBuild Boston also has a
construction curriculum where they learn
the building trades, which has strong ties
to the LEEDS program and local architects

GREEN BUILDING MOVES OUTDOORS
New Rating System to Encourage
Sustainable Landscape Design
San Francisco, CA, October 6, 2007 — The
American Society of Landscape Architects
(ASLA), The University of Texas at Austin’s
Lady Bird Johnson Wildower Center,
and the United States Botanic Garden an-
nounced the development of a new ratingsystem for sustainable landscape design,
called the Sustainable Sites Initiative. The
announcement took place at the 2007
ASLA EXPO in San Francisco, California.
Just as the U.S. Green Building Council’s
LEED® rating system measures a building’s
environmental impact, the Sites Initiative
will measure the sustainability of designed
landscapes of all types, including public,
commercial, and residential projects. The
U.S. Green Building Council is lendingits support to this project and plans to
adopt the Sustainable Sites metrics into its
LEED® system once they are nished.
“This will provide the missing link for
green building standards,” said Nancy
Somerville, Executive Vice President and
CEO of ASLA. “Developers, designers,
owners, and public ofcials will now have
the tools at hand to signicantly increase
sustainability in the built environment,
from interiors to landscapes.”
“We are acutely aware that the best guide-
lines and standards in the world will not
be adopted if they are not cost-effective for
builders and landowners,” said Frederick
R. Steiner, FASLA, Dean of The University
of Texas at Austin School of Architecture
and a member of the Wildower Center
Advisory Council. “Sustainable landscapes
have enormous environmental benets,
and any additional costs should be easily
recovered over the life of the project in
energy, water, and other savings.”
“The U.S. Botanic Garden is extremely
excited to be a part of the Sustainable
Sites Initiative”, said Holly Shimizu,
Executive Director of the Garden. “We
recognize that through partnerships and
collaborations we can make a much
greater impact on promoting and guiding
sustainable design, implementation, and
management of gardens, landscapes, and
all outdoor spaces. This initiative will help
balance the built and natural environ-
ments for the long-term health of commu-
nities nationwide.”
Additional program partners include the
U.S. Green Building Council, the Environ-
mental Protection Agency’s GreenScapesProgram, the National Recreation and
Parks Association, the American Society of
Civil Engineers’ Environment and Water
Resources Institute, the National Associa-
tion of County and City Health Ofcials,
the Nature Conservancy’s Global Invasive
Species Initiative, and The Center for Sus-
tainable Development at the University of
Texas at Austin. For more information, visit

About the Lady Bird Johnson Wildower
Center: The Lady Bird Johnson Wildower
Center at The University of Texas at Austin
is dedicated to increasing the sustainable
use and conservation of native plants and
landscapes. Founded in 1982 by Lady
Bird Johnson, the former rst lady, the
Wildower Center maintains an extensive
native plant botanic garden and offers
professional and adult education. The
Wildower Center also conducts research
on landscape restoration and plant con-
servation at its 279-acre site, promoting
the role of native plants in addressing
ecological problems. Recent research ini-
tiatives focus on native turf grasses, green
roof technology in a sub-tropical climate,
prairie restoration methods including
prescribed re, the control of invasive
species, and ways in which native plants
can aid in combating climate change in
urban landscapes. Learn more at www.

U.S. National Overview
October 2007
For the contiguous United States, the av-
erage temperature for October was 56.9°F(13.8°C), which was 2.1°F (1.2°C) above
the 20th century mean and tied with three
years as the ninth warmest October on
record, based on preliminary data.
Temperatures were generally warmer than
average across the Lower 48 states, with
the exception of cooler than average con-
ditions in the states of the West Coast.

IPCC Fourth Assessment Report
On November 16, 2007 the much antici-
pated “Climate Change 2007”, the 4th
(and nal) Assessment Report from the In-
tergovernmental Panel on Climate Change
(IPCC) was due to be released. On No-
vember 17th, the Synthesis Report, which
summarizes all four individual reports and
presents the ndings in a user-friendly

Jersey, Pennsylvania, and Rhode Island set
record high average temperatures during
October, and the Northeast as a whole
was the 2nd warmest on record. Readings
on October 8th reached levels more com-
mon in the summer months, breaking dai-
ly and monthly high temperature records
in the New York City metro area.
The unusually warm conditions reduced
energy demand for heating in the heavily
populated Northeast, and, for the nation
as a whole, temperature related energy
demand was 15% below average based
on NOAA’s Residential Energy Demand
Temperature Index.
No new low precipitation records were
set; this was the twenty-sixth wettest Oc-
tober in the 1895—2007 record. An aver-
age of 2.56 inches (65.0 mm) fell across
the contiguous U.S. this month, which is0.5 inches (11 mm) above average.
Although above normal rainfall in Oc-
tober led to a reduction of the drought
in parts of western Tennessee, much of
Kentucky, and parts of Virginia and North
Carolina, much of the Southeast remained
in an exceptional drought. Many cities in
the region have instituted mandatory wa-
ter restrictions, with some locations hav-
ing only a three-month supply remaining.
In North Carolina, Gov. Easley has said,“If we do not get signicant rain, some ar-
eas face the once unthinkable possibility
of water rationing and potentially running
out of water entirely.”
More than six inches (150 mm) of rain fell
in many drought affected areas of western
Tennessee in October, much of it in the
last week of the month, but year-to-date
precipitation decits ranging from 10 to
20 inches (250-500 mm) remained wide-
spread. Several communities were al-ready under mandatory water restrictions.
Heavy rain brought some drought relief to
parts of Virginia and North Carolina, but
near the end of October, drought covered
67% of the Southeast.
Drought also continued to affect more
than half of the western U.S. In late Oc-
tober, ongoing drought and strong Santa
Ana winds brought devastating res to
parts of Southern California. According to
preliminary estimates, over 900,000 acres
(3600 km²) had burned during the month
across the southern portion of the state,
burning more than 2000 homes and af-
fecting hundreds of thousands of people.
Based on preliminary estimates from the
National Interagency Fire Center (NIFC),
over 9.2 million acres (37000 km²) had
burned across the U.S. as of the end of
October. Drought, which has affected the
West since the late 1990s, has contrib-
uted to extremely active wildre seasons
in recent years.
The past four years have been the most
active on record in terms of acreage
burned in the U.S. As of the end of Oc-
tober, the 2007 re season was the sec-
ond worst on record, exceeded only by
the 2006 season when 9.8 million acres
(39700 km²) burned.
A dry cold front swept through Southern
California on the 16th, kicking up strong
winds in the Mojave Desert of Califor-
nia. Winds gusting to 60 mph (96 km/hr)
reduced visibility to zero from blowing
dust. Four deaths were attributed to the
sandstorms with dozens of vehicles in-
volved in at least four separate wrecks.
October 2007 was a very busy month
for severe weather across the Midwest.Tornadoes occurred during every week
except the last, with the peak of the activ-
ity occurring during October 17-18, when
67 twisters occurred in the Midwest.
