Guide to the Plant Communities of the Central
Finger Lakes Region by Charles L. Mohler, Peter
L. Marks and Sana
Gardescu. The Central Finger
Lakes region of New York
contains a wide diversity of natural forest and openwetlandplant
communities and communitiesdeveloping on abandonedfarm land. This book, based on over thirty
years of research, describes 24 community types in relation to
environmental and historical factors that control the composition of
vegetation. The book is intended for a general audience, and is lavishly
illustrated with high quality color photographs. An appendix provides detailed
directions to public locations where various community types can be
observed.
It can be purchased at https://www.nysaes.cornell.edu/store/catalog/
and at many bookstores in the region.
Please
take time to view these two informative slide presentations by Chuck Mohler on weed management in
organic systems:
·
ECOLOGY OF WEED MANAGEMENT IN ORGANIC SYSTEMS
·
MECHANICAL WEED CONTROL FOR ORGANIC CROPPING
SYSTEMS
 The
Organic Weed Management Database Website was added. The purpose of this website is to
provide organic gardeners with information about the biology of garden
weeds, including identification, management strategies and ecological
facts that will help you understand your weeds. The basic philosophy is that
understanding the biology of weeds is critical to organic weed management. Although weeds can be useful as
food and as protection for the soil, most gardeners prefer to eliminate
them or strictly limit their abundance. Weeds are neither always bad nor
always good, but usually they tend to be bothersome for the garden.

Cropping Systems Project website below for more

 Weed Watch Project is Underway! Join Today! Do you
have access to an urban vegetable garden? Then, the Weed Watch project is
for you. We encourage gardeners, youth groups, biology classes and other
interested individuals all over North America
to participate. The Cornell University Garden Mosaics program is
developing a database of urban weeds and weed control practices and your
participation is needed. Please tell me
more...
Be sure to take a look at the PDF file
that shows pictorially the weed watch sampling procedure.
 NEW WEED IDENTIFICATION CD PROGRAM NOW AVAILABLE. ORDER HERE VIA

Identification, Biology and Management was originally developed for use
by students in the Weed Biology and Control undergraduate course at
McGill University to assist them to gain
knowledge of, and to recognize important agricultural, environmental and
urban weeds. Learn more...

 Creeping
Charlie/Ground Ivy - Rust Project.
Ground
ivy or creeping Charlie (Glechoma hederacea L., shown below) is a
creeping perennial in the Labiaceae or Mint Family that forms dense
prostrate patches in turfgrass, damp shady meadows, and disturbed sites
(Uva et al., 1997). This plant can also colonize areas exposed to full
sunlight. Reproduction is primarily by creeping stems (i.e., stolons)
that root at the node and less commonly via seed and rhizomes. Ground ivy
is native to Eurasia but has been introduced and become widespread in North America. The control of ground ivy using
chemical and mechanical methods has largely been unsuccessful in
turfgrass where it is considered a major weed (Mitich, 1994; Turgeon,
1994; Lamboy et al., 2000). Effective and environmentally sound
approaches are needed for the control of ground ivy in turfgrass.
 Charles Mohler is a co-author
of the book: Ecological
Management of Agricultural Weeds which is available from Cambridge
University Press.
