2008 APS Forest Pathology Committee Meeting
LaSalle Hilton Hotel Minneapolis, MN
8:30 10:00 pm, July 26, 2008


Jennifer Juzwik was the Forest Pathology Committee chair who presided over the meeting. (These minutes reflect the agenda set by the chair).


  1. Committee Membership Items [Jenny Juzwik]

The Chair noted that there is no numerical limit to members who can serve on the APS committees; however, all committee members must be current members of APS. Each committee member is elected for a 3-year term, and APS regulations permit the extension of expiring membership for another 3 years.

    1. A welcome was extended to the new members of the Forest Pathology Committee: Bill Otrosina, Margaret Mmbaga, and Chris Wallis.
    2. Mee-Sook Kim was thanked for her role as the previous chair.
    3. Members who’s 3-year term expire this year included Gary Chastagner, Mo-Mei Chen, Everett Hansen, Bill MacDonald, David Rizzo, and James Zanzot. Mo-Mei Chen and Bill MacDonald agreed to have their membership extended, but Everett Hansen decided to cycle off of the committee. Other members with expiring terms will be contacted to see if they wish to have their terms extended.
  1. Minutes of 2007 meeting [Jenny Juzwik]

The Minutes of the 2007 Forest Pathology Committee meeting were approved without objection.

  1. Special Sessions 2008 Meeting
    1. Forest Pathology Field Trip [Joe O’Brien, Organizer]

The Forest Pathology field trip was considered a resounding success. During the two-day field trip, urban and rural forest tree disease problems were presented and discussed during visits to the TRE (Teaching, Research and Extension Nursery at the University of Minnesota) and stops between Minneapolis and Cloquet, MN. The first day ended at the Cloquet Forestry Center with an outdoor barbeque and a presentation by Wayne Sinclair on the history of forest pathology in the USA. Logging history and tree diseases (white pine blister rust, Diplodia shoot blight, butternut canker, and ash yellows/decline) were observed on the return trip via the St. Croix River Valley, followed by a boat excursion on the St. Croix River.

The Chair and other members expressed their gratitude to Joe O’Brien for organizing the field trip. Appreciation was also extended to others who contributed to the trip, including Manfred Mielke, Jennifer Juzwik, Mike Ostry, Linda Haugen, Jill Pokorny, Bob Blanchette, and all the speakers.
b.   The Forest Pathology Committee also sponsored two symposia at this year’s annual APS meeting.
1) “Potential impacts of climate change on diseases in natural ecosystems: Using history to predict the future” [Bryce Richardson, Organizer, and Ned Klopfenstein, Jennifer Juzwik, Co-organizers], and
2) “If we had known then what we know now: Reflections on catastrophic tree diseases [George Hudler, Organizer, and Jennifer Juzwik, Co-organizer].

  1.  A display of the Forest Pathologists’ Family Tree was displayed. This display was compiled and created by Kim Camilli and Chandalin Bennett, who were thanked by the committee. Ellen Goheen and others were acknowledged for their initiation of an earlier version of this project for the Western International Forest Disease Work Conference (WIFDWC).


  1. High Priority Forest Pathogen List (for genome sequencing) – [Ned Klopfenstein]

Ned Klopfenstein reported that forest pathogens predominate on the APS list of organisms recommended for immediate priority for genomic sequencing. The Forest Pathology committee is committed to supporting any proposals for genomic sequencing of forest pathogens. In 2008, proposals were submitted for genomic sequencing of Cronartium quericum f. sp. fusiforme (Tom Kubisiak), Armillaria sp. (Dirk Hoffmeister), and Ophiostoma novo-ulmi (Louis Bernier). Richard Hamelin plans take the lead for a C. ribicola proposal. Forest pathogens for which genomic sequencing is completed or ongoing include Phytophthora ramorum, Heterobasidion annosum, Melampsora medusae, Cryphonectria parasitica and others.

6.   Shortage of Forest Pathologists – Update on Actions taken  [Jenny Juzwik]
Considerable discussion was focused on the continuing decline in the numbers of forest pathologists. In general the committee member urge that we do whatever we can to increase visibility, encourage increased funding, and support increased investment in public services that maintain our natural resources. Some believe the decrease is tied to a decrease in forestry professionals, a broadening of professional positions (e.g., forest ecology), or a changes forest industry and diminished long-term perspectives. It was noted that much of the historical build-up in forest pathology was tied to major calamities (e.g., chestnut blight, Dutch elm disease, white pine blister rust, etc.). Currently, there seems to be an ample supply of willing students, but funding support and future job prospects are lacking. Members were encouraged to revisit an article by F.H. Tainter 2003. Perspectives and challenges from the 20th century. Phytopathology 93: 1056-1061. Various members are working to compile documentation for decline in forest pathologists in the federal, university, state, and private sectors. (An APS feature story is being written by Dr. David Gadoury, Cornell University). The committee will consider drafting a letter to APS leadership asking them to urge support from the USDA and Dept. of Interior to recognize and support the need for increasing forest pathologists and professionals in related disciplines.

7.   APS Foundation Student Travel Award – Update [Mee-Sook Kim]
Maria Newcombe was congratulated as this year’s recipient of the Forest Pathology student travel award. Mee-Sook Kim reported $6,182 as the current balance in the Forest Pathology student travel award. Currently, the student travel award is offered every other year. Our initial goal is to increase these funds to $8,000 so that the student travel award can be offered every year. Members were encouraged to help raise funds for the travel award. In addition, members were reminded that they can initiate other “named” travel awards, perhaps named after their favorite professor or other notable person. These named awards can be initiated with a down payment of $2,500.

8.   Forest Pathology Committee Website – Update [Linda Haugen]
Linda Haugen provided an update on the Forest Pathology Committee website, which is currently being hosted by Jim Worrall at the Forest & Shade Tree Pathology site (http://www.forestpathology.org/). A link in the upper right will take you to the APS Forest Pathology Committee (http://www.forestpathology.org/hosted/aps/). The purpose of this website is twofold: 1) to facilitate committee activities, and 2) to be a record and source of information on committee activities. This site has current and historical information from our committee, including committee membership, committee news, future sessions, past sessions, student travel fund, etc.

9.   Other Activities

    1. APSnet Feature Story

Mike Ostry and Jennifer Juzwik were recognized for their APSnet Feature article entitled “Selected forest and shade tree diseases of significance in the 20th century,” which was the feature story in May 2008 (http://www.apsnet.org/online/feature/tree/).  Forest Pathologists were encouraged to read this article, if they have not already done so.

4.   Forest Pathology News and Updates

    1. Special recognitions of forest pathologists  [All]

This year, Mike Wingfield will be honored as an APS fellow.

    1. Thousand cankers disease of black walnut [Ned Tisserat]

Ned Tisserat provided current information on a recently discovered disease on black walnut, called thousand cankers disease. The disease is associated with attack by walnut twig beetle (Pityophthorus juglandis) and fungal associates of the beetle (Geosmithia sp.). Fusarium solani is also associated with canker formation. This disease is of concern because it has been observed in several western states, which are outside of the native range of black walnut. The threat to native walnut is currently unknown. Forest pathologists are urged to be aware of this disease and report any new findings to Ned Tisserat (ned.tisserat@colostate.edu).

    1. Climate change and forest diseases [USDA Forest Service R&D pathologist]
    2. Upcoming meetings related to forest pathology [All]

Adaptations of Forests and Forest Management to Changing Climate with Emphasis on Forest Health, 2008, August 25-28, Umeå, Sweden, IUFRO/FAO/SLU.
Members were encouraged to refer to Jim Worrall’s Forest & Shade Tree Diseases website (http://www.forestpathology.org/) for information on upcoming forest pathology meetings.

  1. Memoriam

The committee noted the passing of Alex Shigo and Ed Wicker, and offered their respect for their exemplary service.

  1. Other

Ellen Goheen reported that the former students of J.R. Parmeter and Fields W. Cobb at UC-Berkeley recently had a reunion in Idaho.

Gaston Laflamme noted a new website on fungal wilt diseases (http://www.wilt-ism.net/page1.aspx)

Mo-Mei Chen is proposing a USA-China exchange in forest pathology. One goal is to introduce North American forest pathologists to China, and vice versa. Another goal is to encourage younger forest pathologists to engage in international cooperation. This project could lead to a workshop for forest pathologists in northeastern China, and other cooperative projects. The Forest Pathology Committee is seeking ideas on how we can contribute to this exchange.

Mo-Mei Chen also has completed a draft of her book on rusts of pine, which will be published by CABI.

The 2009 APS annual meeting will be in Portland, Oregon, followed by Nashville, Tennessee in 2010, and Hawaii in 2011.
