Invasive Pest and Firewood Outreach in Utah

Guest blog by Lori Spears, Invasive Species Survey Coordinator for Utah State University Extension

Invasive species are a growing threat to our nation’s agricultural and natural resources. In Utah, nearly a dozen insect and disease pathogen pests have arrived over the last decade, including spotted wing drosophila (SWD) and brown marmorated stink bug (BMSB). These two insects  were first detected in Utah in 2010 and 2012, respectively. Although they have not yet reached economically injurious levels in Utah, they occur in fruit and vegetable production sites and have the potential for significant negative impacts. Another invasive insect, the emerald ash borer (EAB), is expected to reach Utah in the near future. EAB is known to occur in 27 eastern and mid-western states, and is rapidly expanding its range. It has not yet been found in Utah, but an infestation has been found in neighboring Boulder, Colorado. Unfortunately, research shows that EAB is generally established in an area for several years before it is detected, and so there is a chance that EAB is already present in Utah.

2017 Poster Designs for Utah Based Forest Pest Outreach

In response to new and emerging invasive insect threats, Utah’s plan for invasive pest and firewood outreach include preparing the citizens of Utah with the knowledge and skills necessary to identify potential invasive insects and/or help stop their introduction and spread. Involving everyday citizens in early detection of invasive species has been highly successful across the United States. For example, it was a trained Master Gardener who first detected the Japanese beetle (Popillia japonica) in Orem, Utah, which led to the Utah Department of Agriculture and Food implementing an intense eradication program to prevent its establishment. Utah’s interagency partnership group includes the Utah Plant Pest Laboratory at Utah State University (USU), USU Extension, the Utah Department of Agriculture and Food, and USDA-APHIS-PPQ.

This year’s activities include:

  • Conducting several First Detector Training workshops along the Wasatch Front (the greater Salt Lake City region) in Utah
  • Participating in farmer markets and other community events throughout the state
  • Creating and placing billboards that highlight the threats associated with invasive pests
  • Designing and placing permanent outdoor interpretive signs that focus on the pathways of invasive pest spread
  • Conducting a Junior Master Gardener training program, whereby youth will tie ribbons and informational tags on ash trees to emphasize the number of trees that could be killed by EAB.

Hope for Hawaiʻi’s Threatened Keystone Tree, ʻŌhiʻa

Guest blog by Corie Yanger, Rapid ʻŌhiʻa Death (ROD) Educational Specialist, University of Hawaiʻi Extension

If you were to ask biologists and cultural practitioners in Hawaiʻi what the most important tree is in the state, “ʻōhiʻa” would likely be the answer. Not only does ʻōhiʻa (pronounced oh-hee-yah, or oh-hee-uh) cover roughly 1 million acres across the Hawaiian Islands, it is one of the first flowering plants to establish on fresh lava flows, and a keystone species of native wet forests. Consequently, one of the largest threats to the health of Hawaiʻi’s native forest ecosystems would be a pest or disease that kills ʻōhiʻa. In the last several years, that threat has surfaced – Rapid ʻŌhiʻa Death (ROD).

ROD is a fungal disease that has killed hundreds of thousands of ʻōhiʻa trees and affected more than 50,000 acres of forest in Hawaiʻi. All confirmed cases of ROD-infected trees are located on the largest island, called Hawaiʻi Island or Big Island. Prior to infecting trees on Hawaiʻi, this disease was not known to the scientific community.

The fungus enters a tree through a wound (such as a scraped area in the bark, or a cut limb), establishes within the sapwood (where the water-conducting cells are located), and eventually stops water flow within the tree. Months or even a year may pass before the tree shows outward symptoms. ROD causes green leaves of entire trees to turn yellow, then brown, in just a few days to several weeks. This rapid progression is how the disease got its name, Rapid ʻŌhiʻa Death.

Researchers recently discovered that the disease symptoms people see are actually caused by two different introduced species of fungus in the genus Ceratocystis. The species cause slightly different symptoms, but the differences are too subtle to tell apart in the field. The species are genetically unique from any other fungal species ever found associated with ʻōhiʻa, and will soon receive their own new species names.

In Hawaiʻi, ʻōhiʻa gather the rain that recharges our island aquifers. In that same way, ʻōhiʻa have also gathered scientists, managers, educators, cultural practitioners, and many more groups together to combat Rapid ʻŌhiʻa Death. A large partnership of non-governmental and governmental organizations formed a ROD Working Group in 2015 to coordinate research, management, and outreach. This working group has facilitated important advances in our understanding and tracking of ROD, through aerial surveys and field detection, mapping suspect ROD-affected trees and areas, and identifying the potential vectors that most likely spread the disease.

The ROD working group has also assisted the Hawaiʻi Department of Agriculture by providing science-based support for a quarantine rule restricting movement of ʻōhiʻa material and soil off of Hawaiʻi Island- including the movement of ʻōhiʻa firewood and posts. A statewide ROD prevention program reaches thousands of Hawaiʻi’s residents and visitors every day through printed media, radio, internet, community talks, school presentations, landowner visits, and informational tables.

Researchers do have hope despite the severity of the ROD situation. ʻŌhiʻa is a highly variable genus with eight named varieties of Metrosideros polymorpha and four other species of Metrosideros found on older Hawaiian Islands. With such high genetic diversity ROD researchers are testing the different varieties and species to see if disease resistance exists naturally. Another area of hope lies in observations of heavily impacted forests. Where ROD-related ʻōhiʻa tree loss has been the worst, meaning 75% or greater, researchers still see living, apparently healthy trees. Future studies will test cuttings from those healthy individuals to see if the trees are resistant to ROD.

Protecting Massachusetts Campgrounds and Natural Resources

This blog was originally posted on the Massachusetts Introduced Pests Outreach Blog on March 7th 2017.

Though it’s cold outside now, the spring camping season is rapidly approaching! While many campers like to bring their own firewood to campsites, the invasive wood-boring insects Asian longhorned beetle (ALB) and emerald ash borer make frequent use of firewood to transport themselves to new infestation sites. Worcester has already lost 36,000 trees to date due to the ALB, so the economic and environmental risk these invasive pests pose to the rest of New England’s hardwood forests is immense.

In order to help spread awareness of these pests and the risk they pose, we offer a variety of free outreach materials, including ID cards, pamphlets, and laminated posters suitable for display outdoors. We (staff at Massachusetts Department of Agricultural Resources) also offer “Don’t Move Firewood” material that encourages campers to buy their own firewood at campsites. You can order your free materials using this Google Docs form.

Campers should be aware of the risks involved in moving firewood, even to nearby towns. It is a good idea to be aware of where at each campground you can purchase firewood.

If you want to update your campground’s website with information pertaining to invasive forest, here is some suggested wording:
Bringing firewood from home when you go camping could put your favorite campsite in danger. Tree-killing insects and diseases can hitchhike in firewood and use it to spread to new areas. Instead of bringing firewood with you when you go camping, buy firewood from a location close to where you camp.

For more information, see:

It is the responsibility of all Massachusetts citizens and visitors to make sure we are preserving our natural resources, and being aware of these invasive insects and how to combat their spread is part of that.

Having Fun with Outreach at the Vermont Flower Show

Guest blog by Meredith Whitney, Forest Pest Outreach Coordinator with University of Vermont Extension

Thousands of Vermonters come out of the woodwork every other year to witness the colors, smells, and excitement of the Vermont Flower Show. Upon arrival to the Champlain Valley Exposition in Essex Junction, Vermont visitors first walk through the main garden display. As the Forest Pest Outreach Coordinator with the Vermont Urban and Community Forestry Program, I have the opportunity to attend events such as the Flower Show, where I can reach large numbers of highly engaged members of the public.

This year, we paid for a 10 x 10 booth in the exhibition hall and displayed large images of the emerald ash borer (EAB) and Asian longhorned beetle (ALB). The Flower Show was a terrific opportunity to use one of the two interactive “face-in-hole” banners that we recently designed. The banners are a fun way to spread the message about not moving firewood and work perfectly for social media posts. Having interactive components to our displays has doubled the number of people who stop by. The banners appeal to young children, their parents, and to many millennials- and each person that takes a photo creates a permanent and shareable reminder about these forest pests, right inside their smartphone!

The Flower Show was bustling this year. All three days were busy and our booth was always full of people asking questions about invasive insects. We recorded 719 people that came and looked at the display. I was surprised at how much people already knew. Nearly everyone who stopped by had heard of at least one of the two pests. The most common response I heard was, “I’ve seen those!” Since neither EAB or ALB have been detected in Vermont yet, I would walk people over to the insect samples, showing them how small the EAB really is, or how similar ALB is to the native six-spotted tiger beetle.

In many cases people felt hopeless at first, and they ask if there is anything they can do about the emerald ash borer. Much like me, they are stunned that it hasn’t shown up in Vermont yet. Last year, Vermont passed a law banning the importation of untreated firewood into the state. We tell them that the simplest and easiest way to slow the spread of invasive species is to buy firewood where you burn it. It is my hope that exhibits like ours at the Flower Show will inspire people to do their part and make a difference.

Webinar: The People Have Spoken on Jan 25 2017

Join us for a FOCI webinar, The People Have Spoken: Using Forest and Firewood National Polling Data to Promote Forest Health, on January 25 at 11am MDT (1pm Eastern). This webinar will discuss results from a national survey of citizen attitudes toward invasive species, firewood movement, and forest health. This webinar is jointly sponsored by the SREF Forest Health and Invasive Species Program and the Firewood Outreach Coordinating Initiative.

Invasive species are a major forest health threat in North America, costing federal, state, and local governments billions of dollars annually for monitoring, management, and mitigation of impacts.  Landowners are often negatively affected when forest ecosystems are changed and they lose valuable trees to invasive pests.  Human-mediated movement of invasive species is a common method in which pests travel long distances.  Using data from a national survey of U.S. citizens, this webinar will discuss people’s attitudes and knowledge towards invasive species and the relationship with firewood.  We will consider these data, and the common perceptions of individuals who routinely frequent the outdoors, in the broader context of forest health.

This webinar is now completed!
