TERRESTRIAL INVERTEBRATES & PLANT DISEASE-CAUSING MICROORGANISMS
SAG Members- Dr. Ken Raffa - Professor of Forest Entomology, UW Madison; Dr. Gen Stanosz - Professor of Forest Pathology, UW Madison, Melody Walker - Plant Pest Survey and Control Section Chief, DATCP; Anette Phibbs - Plant Pathologist, DATCP; Linda Haugen - Forest Pathologist, USDA Forest Service; Art Wagner - Plant Pathologist, USDA APHIS; Karen Danielsen, Forest Ecologist, GLIFWC; Facilitator- None; DNR Staff- Jane Cummings Carlson, Division of Forestry; Meeting Date - 9-20-07; Other Attendees- Dr. Lee Frelich
Amynthas spp.	Crazy worms	6					PROHIBITED	Dr. Lee Frelich discussed the current status of earthworms in the genus Amythas. Dr. Frelich's input, as along with the literature review support prohibition. The species in this genus are not widespread in WI, have a high potential for producing damage and thriving in WI's climate. These species are primarily used for composting but are also in the bait industry; other species are available for composting and bait that are not as damaging to the forest environment.	PROHIBITED no need to list 7 species
Acanthodrilidae, Lumbricidae, Megascloecidae	Earthworms						Further information needed for classification.	The SAG determined that there was not enough information to place all earthworms (other than the Amythas spp.) into one classification. SAG members would like to have further information about specific species and revisit this question in December '07 or January '08. A research scientist working on earthworms has agreed to provide further review of earthworms for the SAG.	no action- need to engage compost and bait industry
Sirococcus clavigignenti-juglandacearum	Butternut canker pathogen			7			CAUTION	The widespread distribution of this pathogen in Wisconsin's forest environment, the pathogen's ability to spread rapidly and the lack of management options led the SAG to classify this pathogen as caution. No regulatory actions would impact this pathogen in a meaningful way. Continued monitoring is valuable as silvicultural management is an option for maintaining butternut in Wisconsin's forests.	CAUTION
Agrilus planipennis	Emerald Ash Borer	7					PROHIBITED	Since this organism is not known to be in Wisconsin, has a high potential for establishment and injury and has a low potential for being controlled, the SAG determined it qualifies for being prohibited.	PROHIBITED
Harmonia axyridis	Multicolored Asian Ladybeetle			4	2		CAUTION	This organism is widespread throughout Wisconsin. It has the potential to cause human health issues as some individuals are allergic to fluids secreted by this beetle. Continued monitoring of the Multicolored Asian Ladybeetle is important as new management options may become available.	CAUTION
Anaplophora glabripennis	Asian Longhorned Beetle	6					PROHIBITED	The Asian Longhorned Beetle is not known to be present in Wisconsin. This organism's high potential for causing mortality to several native species of trees in Wisconsin and its high potential for introduction, led the SAG to classify it as prohibited.	PROHIBITED
Adelges tsugae	Hemlock woolly adelgid	6					PROHIBITED	The hemlock woolly adegid is not known to be present in Wisconsin. Hemlock is not a common tree species in the state but does inhabit very sensitive ecosystems and plays a significant role in those environments. Loss of hemlock from these environments in the eastern United States has had a significant impact on the ecosystem. Control options are limited to pesticide sprays and biological controls (which have not been very successful).	PROHIBITED
Lymantria dispar	European Gypsy Moth		6				RESTRICTED	The European Gypsy Moth is widespread in eastern Wisconsin yet restricting movement from infested areas into non-infested areas is still an important option for managing the spread of this organism. Maintaining restrictions on movement will supplement the statewide gypsy moth slow the spread and suppression program.	RESTRICTED
Lymantria dispar	Asian Gypsy Moth	6					PROHIBITED	The Asian gypsy moth has not been found in Wisconsin. Unlike the European gypsy moth, the Asian gypsy moth female can fly. Thus, the potential for faster spread is high. This organism feeds on several native species of forest trees. There are a number of options for managing this insect but the combination of dry summers and defoliation will cause significant tree mortality in Wisconsin's forests.	PROHIBITED
Cronartium ribicola	White Pine Blister Rust			6			CAUTION	White pine blister rust is widespread throughout Wisconsin. Recent surveys show this disease is limited to areas where the microclimate and presence of the alternate host allow the pathogen to infect white pine. There are several silvicultural management options that are very effective in minimizing the impact of white pine blister rust. Regulating this disease would not change its potential for spread or impact. Continuing to monitor its presence, incidence and severity are important.	CAUTION
Cryptococcus fagisuga	Scale associated with Beech Bark Disease	5	1				PROHIBITED	This scale alters the bark of beech in such a way as to make it susceptible to infection by a native and an exotic canker-causing Nectria fungus. The combinatin of the scale and fungus cause beech bark disease, which eventually kills the tree. The beech resource is limited in Wisconsin to the northeastern part of the state yet is abundant in localized areas. Resistance to beech bark disease is uncommon; loss of up to 95% of Wisconsin's beech resource is expected.	PROHIBITED
Phytophthora ramorum	Sudden Oak Death pathogen	6					PROHIBITED	This pathogen is not known to be present in Wisconsin. Phytophthora ramorum has caused significant levels of mortality to several tree species in CA and OR. Northern red oak is considered an "associated species", which means it can be naturally infected but the scientific process of inoculating the host, observing disease symptoms and reisolating the pathogen (Koch's postulates)have not been completed. The USDA national risk map shows Wisconsin is at a low risk for impact from this pathogen, primarily due to climate restrictions. The pathogen is very adaptable, thus, the SAG chose to prohibit this fungus due to the unpredictability of the pathogen and the potential damage to Northern red oak.	PROHIBITED
Arion fasciatus	Orange-banded arion (slug)					6	CAUTION	Dr. Joan Jass wrote a review paper on the satus of taxonomy, and the potential impact of snails and slugs to Wisconsin's forest ecosystem. Dr. Jass also summarized the current status of surveys showing known distribution of various species. Identification of snals and slugs can be extremely difficult. Some speices may easily be misidentified and there is not agreement among taxonomists regarding the latin names of certain species. There is very little data on the distribution of snails and slugs in Wisconsin and the surrounding area. There is virtually no data on the impact snails and slugs hae or could have on the forest ecosystem. All of these factors led the SAG to list snails and slugs as "caution" species. The organisms listed below are all known to be nonindigenous gastropods present in WI.	CAUTION
Arion hortensis	Garden arion (slug)					6	CAUTION		CAUTION
Arion rufus	Chocolate arion (slug)					6	CAUTION		CAUTION
Arion subfuscus	Dusky arion (slug)					6	CAUTION		CAUTION
