Learn to ecologically manage the good bugs of the insect
world. Sharon Collman, IPM Outreach Coordinator for
EPA Region 10, has been teaching pest management and
plant problem diagnosis for more than 25 years. This class
is for everyone who has identified and eliminated a “pest”
in a client’s garden only to find out later that they had
eliminated a natural control for other pests. Via slides and
up-close specimens, learn about the “bugs you can love”
that are working for the garden. Sharon promises to make
this class an enjoyable bug-enlightening experience.

The Art and Science of
Transplanting

ISA CERTIFIED ARBORIST CREDITS PENDING

This five-hour class at the Washington Park Arboretum
will mix lectures and field demonstrations. Dr. Linda
Chalker- Scott will discuss the science behind transplant-
ing. Arboretum staff and local experts will demonstrate
how to ball and burlap in our poor glacial till soils as well
as transplant bare-root and container-grown trees. After
lunch, Olympic Trees owner Todd Holmes will transplant
a 30-foot maple tree with his 90-inch tree spade. Learn
how this expert evaluates a site, access for the machine,
soils, species and shape of tree, and other factors that must
be weighed when moving trees with a tree spade.

Pesticides; their Impact and
Your Role

This class is intended for any current and future pesticide
applicators. It will present startling results from research
studies at the UW that measured children s exposure to
pesticides in an effort to understand where the exposures
came from and how they can be minimized. The effects of
pesticides on salmon and other wildlife will also be covered,
and will be followed up by practices that individual
applicators can employ to reduce the impact of the
pesticides.

Dr. Alex Lu, Senior Research Associate with the U.W.
Department of Environmental Health, will speak on
pesticide exposure found in Washington’s children.

Dr. John Stark, Professor/ Research Scientist, Ecotoxicology
Program, WSU Puyallup, will speak on the effects of
pesticides on salmon and wildlife.

Gina McCauley, IPM Consultant/Owner of G.I.N.A.-
Green Industry Needs Assessment and former President of
WSNLA, will speak on how applicators can reduce
detrimental impact.

Basic Soils and Soil Testing

Tuesday December 3, 9 a.m. to noon
NHS Hall, Center for Urban Horticulture
Fee $35; pre-registration required.

WSDA PESTICIDE RECERTIFICATION CREDITS PENDING

The garden, lawn, or landscape is no better than its underly-
ing soil. Dr. Craig Cogger, Extension and Research Soil
Scientist with WSU Puyallup, will cover the topics of soil
texture, structure, organic matter, nutrients, and pH, as well
as why soil tests are important, and how to interpret their
results.

AUTUMN 2002

Mark your calendars! A symposium titled “Tools and
Techniques to Manage the Urban Forest” will be held on
March 1 3 and 14, 2003 at CUH. Its mission is to review
how urban forestry, environmental horticulture, and social
sciences create strategies to manage natural resources in
the urban environment. For more information, check the
web site at www.urbanhort.org or phone 206-543-3889.

Kathy Wolf, a research social scientist at CUH, is

researching the public response to transportation corridors
and the urban forest. In July 2002 Dr. Wolf was awarded a
$ 1 24,000 grant by the USDA Forest Service for an
additional research project on the topic. The National
Urban and Community Forestry Advisory Council conducts
an annual grant program to benefit urban and community
forests. Wolf’s research will explore the safety implications
of trees in urban transportation corridors, and develop risk
management guidelines for roadside design and planning.

A team of scientists in Australia is studying the
capacity of interior plants to bioremediate the many volatile
organic compounds (VOCs) found in indoor air. VOCs are
the result of plastics outgassing and office equipment
operations, among other things. They are potential
carcinogens and neurotoxins. In small doses they can affect
our work productivity and concentration. The scientists
have found that indoor potted plants absorb and metabolize
VOCs through a combination of leaf cell and soil
microorganism activity. A fascinating finding, being further
studied, is that the plant-pot system "gets better with
practice” at metabolizing the toxins.

OSU Extension has developed a Web site to aid in the
control of bamboo mite.The site outlines biology, damage,
culture and both biological and chemical controls. Growers
need to be most concerned with bamboo mites from the
families Tetranychidae, Eriophyidae andTarsonemidae.
“These tiny mites may seem pretty small to deserve their
own Web site, but bamboo mite is one of the leading
problems in bamboo production worldwide,” said Robin
Rosetta, ext. agent at OSU’s N. Willamette Research &
Extension Center in Aurora, http://osu.orst.edu/dept/
