Be On The Lookout!
Although the new
Terrestrial Invasive Species Field Guide
lists 60 invasive plant species, the following six pose the
greatest threat to the forests of north central Wisconsin and UP. The six species with corresponding field guide page
numbers are: Garlic Mustard p. 54; Common and Glossy
Buckthorn pp. 12 & 17; Eurasian Bush Honeysuckles p.
16; Japanese Barberry p. 20; Japanese Knotweed p. 66. PIF members are urged to be on the lookout for these
species and to implement eradication or control programs on
Wisconsin Headwaters Invasives Partnership
WHIP is a multi-partner co-op consisting of Federal, State, Tribal
and County government agencies plus local non-profit organizations
and schools specializing in environmental education. These groups
work together under a memorandum of understanding which encourages
and formalizes the cooperative relationship necessary for effective
management, coordination and implementation of invasive species
Forestry Best Practices for Invasive Species:
The Wisconsin Council on Forestry has issued a Forestry Best
Management Practices Manual for Invasive Species. The manual offers
voluntary practices that can be integrated with forest management
activities. The manual includes standards of practice that will aid
landowners, land managers, and loggers in limiting the introduction
and spread of invasive plants, invertebrates, and diseases.
mission is to reduce the impact of invasive plant species in the
Midwest. MIPN includes a diverse group of participants and partners
with Purdue University, the Nature Conservancy, the U.S. Forest
Service and the Wisconsin DNR playing major roles in the leadership
of this network.
National Invasive Species Information Center:
plants are introduced species that can thrive in areas beyond their
natural range of dispersal. These plants are characteristically
adaptable, aggressive, and have a high reproductive capacity. Their
vigor combined with a lack of natural enemies often leads to
IPAW - Invasive Plant Association of
The Invasive Plant Association of
Wisconsin (IPAW) is an organization comprised of agencies,
organizations, and individuals concerned with the spread of invasive
plants and their impacts on natural ecosystems. The IPAW mission is
to promote better stewardship of the natural resources of Wisconsin
by advancing the understanding of invasive plants and encouraging
the control of their spread.
Wisconsin DNR Invasive Species Web Site:
Invasive plants, animals and pests are taking a toll on Wisconsin’s
lakes, rivers and landscapes. The DNR is working with citizens and
partners to slow the spread of invasive species. Through educational
outreach, strategic planning and active management we are protecting
our environment and economy from invasives.
Wisconsin DNR Invasive Species Publications:
pamphlets, magazines, multimedia, web resources for educators and
classroom resources & curriculum.
consortium has formed to develop an on-line, GIS-based, all-taxa
invasive species mapping tool to be called iMapInvasives
which will focus on serving the needs of invasive species managers.
Having access to strategic invasive species location information can
support and enhance this important invasive species management work.
Forest Health Protection:
forests are generally in good health, yet numerous native and exotic
insects and diseases and extreme weather events threaten their
health annually. The Forest Health Protection
provides insect and disease management assistance on 16 million
acres of state, private, industrial and county forest lands. We also
assist with forest health monitoring and forest insect and disease
education. Periodic forest health newsletters are published and can
be accessed from this web site.
Planning to cut pine trees
on your property? Then you need to know how to protect your woodlands
against the “circles of death” of Heterobasidion root rot, the
most damaging disease in temperate conifer forests of the world which
has become an epidemic in Wisconsin. Thinning of pine plantations or
cutting of conifer trees can expose your woodland to this deadly
disease. Failure to aggressively respond to the discovery of this lethal
pathogen has threatened sustainable management of Wisconsin's pines and
other conifers in commercial forests, and also endangers trees in
recreational woodlands and in wooded residential and vacation
Red Pine Pocket Mortality:
pine pocket mortality, caused by a complex of insects and the fungi
Leptographium terrebrantis and L. procerum was first
identified in Wisconsin in 1975. National distribution of this
syndrome is unknown. Thinned, plantation-grown red pines between the
ages of 30-45 are most likely to show symptoms of this syndrome.
Mustard is a rapidly spreading woodland weed that is displacing
native woodland wildflowers, vegetation and sprouting trees. It
dominates the forest floor and can displace most native herbaceous
species within ten years. This plant is a major threat to the
survival of Wisconsin's woodland herbaceous flora and the wildlife
that depend on it.
In DA Woods --Spread
the Word not the Seeds:
If you drive any vehicle on an unpaved road surface, chances are
you are helping disperse the seeds of plants. This may not seem
like a problem unless those seeds are from non-native invasives.
Residence time determines invasiveness and performance of garlic
mustard (Alliaria petiolata) in North America:
biological invasions have the potential for large negative impacts
on local communities and ecological interactions, increasing
evidence suggests that species once considered major problems can
decline over time. Declines often appear driven by natural enemies,
diseases or evolutionary adaptations that selectively reduce
populations of naturalised species and their impacts. Using
permanent long-term monitoring locations, we document declines of
Alliaria petiolata (garlic mustard) in eastern North America with
distinct local and regional dynamics as a function of patch
Forestry Best Practices for Aquatic invasive Species:
Wisconsin developed the forestry BMPs in response to federal
legislation. Section 208 of the 1977 Clean Water Act and Section 319
of the 1987 Water Quality Act requires each state to develop
procedures and programs to reduce nonpoint source pollution,
including silviculturally related sources, to maximum extent
Aquatic Invasive Species
Non-native, exotic, alien, non-indigenous - no matter what you
choose to call them, non-native species are plants and animals
present in an ecosystem beyond their native range. Some of these
species become "invasive", and may threaten native
species and interfere with commercial, agricultural, or recreational
activities. In their native environments, there are typically
predators, parasites, pathogens, and competitors that keep these
invasive species in check and create a balance.
