Power Hours-Invasive Species Communication Through Collaborative Webinars

The collaborative webinar project Emerald Ash Borer University (EAB-U) was established in 2009 to address pressing communications needs regarding the invasive emerald ash borer in the midst of national financial crisis. The 40 EAB-U webinars to date have been viewed over 10,000 times. Results of a post-webinar survey evaluating audience composition, impact, and participant satisfaction are presented, and suggest EAB-U webinars reach key audiences who share and apply learned information. Extension professionals faced with complex issues such as invasive species should consider a collaborative webinar approach to efficiently communicate harmonized messages in a cost effective manner.

Invasive species are widely recognized as critical threats to global biodiversity, agriculture, and natural resources (Aukema et al., 2011; Pimentel, Zuniga, & Morrison, 2005). As our understanding of invasion pathways and the role of human transport in spreading invasive species has increased, so too has the importance of public education and outreach. Invasive species education and management are thus increasingly important aspects of the duties of agriculture and natural resources Extension professionals at local, state, and federal levels (Sundermeier, 2005).

In a time when many state and federal agencies are experiencing budget cuts and some states are terminating their Extension programs altogether, cross-agency collaborations can help reduce costs and increase efficiency and impact. Indeed, cooperation between agencies with convergent outreach missions has been highlighted previously as a method of enhancing impact (Rodewald, 2002) and stretching shrinking budgets by merging resources (Ober, Giuliano, & Dillard, 2012). Often government agencies lack critical personnel, infrastructure, and/or local contacts to carry out successful, coordinated outreach programs, but Cooperative Extension services specialize in doing just that. Collaboration, interdisciplinary research teams, and projects with regional or greater impact are imperatives in today's competition for dwindling funding resources (Carter, 2004; Katz & Martin, 1997; Melin, 2000).

Detection of the tree-killing emerald ash borer (EAB) in Detroit in 2002 necessitated interagency cooperation to develop and communicate a coordinated message to clientele. Despite state and federal efforts to contain or slow spread of this pest, by 2008 it had spread to 10 states and two Canadian provinces. Researchers were developing improved approaches to protect ash trees in landscapes and to help slow the progression of ash mortality (Herms et al., 2009; McCullough & Mercader, 2012; Sadof, Purcell, Bishop, Quesada, & Zhang, 2011). Unfortunately, the capacity to get this information to landowners, managers, and decision makers was curtailed after the stock market crashed in late 2008, which resulted in slashed federal and state support for educational programs and travel budgets for continuing education. A more efficient and economical educational approach was needed.

The EAB University (EAB-U) Webinar Project

In response to this need, the EAB-U webinar project was developed in 2009 through a collaborative effort between Michigan State University, Purdue University, and The Ohio State University, funded by USDA Forest Service. The goal is to deliver accurate, timely information about EAB and other regionally important forest pests to stakeholders at no cost to the participant. This open-access, Web‐based educational initiative is housed at Experts in forest pest research and management are invited by EAB-U organizers to present 50-minute webinars, which are followed by a 10-minute question and answer period. Presenters' affiliations are diverse, with local, state, federal, and private agencies from across the nation represented (Table 1). Webinars are publicized through regional email listservs maintained by EAB-U organizers and in select trade magazines. Webinars have been used as educational tools for other Extension issues and have been shown to be a cost-effective and well-accepted method for reaching diverse audiences (Allred & Smallidge, 2010; Cecil & Feltes, 2002; Rich et al., 2011).

The Webinar Platform

EAB-U webinars are hosted with Adobe® ConnectTM software licensed to Michigan State University. Integrated chat boxes allow instant messaging among viewers and presenters, and all webinars are recorded and archived for access on demand. The format requires only an Internet connection, computer speakers, and a spare hour. There is no cost to participants, and no registration, software downloads, or specialized equipment is needed.

Assessing Impact—Survey and Results

Since EAB-U's inception in 2009, 40 different EAB-U webinars have been hosted, recorded, and attended by more than 2,600 live participants. Recorded webinars were downloaded over 7,800 times, yielding an overall ratio of three asynchronous views for every live participant. For individual webinars, this ratio was sometimes as high as 20:1.

To evaluate impacts and potential outcomes of EAB-U programming, a voluntary survey was administered over the course of 15 webinars in 2012-2013 using Qualtrics survey software, Copyright© 2013, licensed to Purdue University. Participants were provided with a link to an online survey following each webinar. Survey completion was incentivized with the offer of "EAB University Goodie Bags" for the first 10 respondents. There were 260 survey participants (37% of total live viewership during this time period).

Geographical Reach

Question 1: In what state do you live and work?

Survey respondents hailed from 30 U.S. states and Canada (Figure 1.) Not surprisingly, the highest concentrations of respondents came from states experiencing the greatest EAB impacts, but it was also encouraging to see viewership in states with no detections of the insect (e.g., Maine, Montana, New Hampshire, Texas).

Most respondents (84.6%) ranked themselves as "very satisfied" with the quality and relevancy of webinar content (Table 2). In addition, webinars also appeared to increase participants' knowledge of subject matter and result in enhanced level of preparation to manage the pest. Finally, most participants (95.3%) indicated that they would share information gleaned from webinars with others, further magnifying impacts.

Demographic Reach

Question 6: What is your primary perspective when viewing this webinar?

Nearly 30% of the respondents were directly involved in making management decisions in the field (woodland owners, foresters, and arborists), indicating a desirable direct transfer of the latest research to those who will implement it (Figure 2). Another 22% identified as professional or para-professional educators (Educator or Master Gardener), who will presumably share the information with a broader audience, increasing the likelihood that pertinent information would continue to "trickle down" to others through these primary trainees.

Question 7: Please list one specific action that you plan to take in the next year as a result of viewing today's presentation.

The vast majority of survey participants (87%) indicated a plan to act as a result of viewing the webinar. These actions could be placed into two broad categories: (1) Education—plans to share learned information and educate others and (2) Action—plans to perform a management action. Proportions of participants planning Education (43%) and Action (40%) were similar, with 4% of participants indicating they planned both Education and Action.

Conclusions and Recommendations

EAB-U represents a model of collaboration among institutions and demonstrates the feasibility of using webinar technology as a cost-effective means for timely distribution of research results and new innovations. This strategy is particularly relevant for invasive species and other topics where new information is continually generated. EAB-U uses expertise from a nationwide pool of presenters with various professional affiliations and draws viewership from unique contact networks at three state universities. These attributes facilitate continued development of the project and provide a means to communicate a coordinated message to a geographically and demographically broad audience. Live participant surveys indicated high levels of satisfaction with the platform and suggested meaningful changes in behavior. Moreover, the 3:1 ratio of downloads to live views indicate the target audience is willing to take advantage of asynchronous training opportunities. Collaborations such as these will be increasingly important to offset diminishing resources available for Extension programs.
