NC State\u2019s Center for Geospatial Analytics and the USDA Animal and Plant Health Inspection Service (APHIS) are collaborating on several projects that use dynamic modeling to help decision-makers curb the spread of economically and ecologically destructive pests and pathogens.<\/span><\/p>\n

Predicting the Future <\/b><\/h2>\n

Center Director Ross Meentemeyer; postdoctoral scholars Chris Jones, Vaclav Petras, and Anna Petrasova; and Forestry and Environmental Resources Ph.D. student Devon Gaydos are developing a novel<\/span> computer model called PoPS (Pest or Pathogen Spread) to run management simulations in an easy-to-use online environment<\/span>. PoPS is the result of the early work of Meentemeyer, who created the first mapped model in 2011. <\/span><\/p>\n

Since then, new pests and pathogens have created a need for new models. Rather than piecemealing one model after another, Gaydos said she and her colleagues are creating a framework so different scenarios can be inputted easily, allowing stakeholders wider access to simulations. <\/span><\/p>\n

Simulations help land managers know what to expect and how to prioritize management of pests and pathogens through seeking out funds, budgeting wisely and choosing other similar options. Simulations also help determine whether new infestations can spread in specific geographical conditions, giving managers the upper hand in proactive responses. <\/span><\/p>\n

Pre-PoPS disease models were difficult to use. Without coding or GIF experience, land managers didn\u2019t have the time to figure the models out, so they simply set them aside. <\/span>The research team is changing that by making the models as user friendly as possible. They\u2019re developing a website to accompany the PoPS model, which will make it accessible and convenient.<\/span><\/p>\n

Also, for a non-computerized resource, they\u2019ve created an interactive \u201cTangible Landscape\u201d made from fiberboard. The landscape is set up like a table, allowing stakeholders to come together, tangibly simulate different scenarios and \u2014 with the click of a button \u2014 see the results of their management choices. <\/span>This groundbreaking technology gives decision-makers the information they need to make sound decisions about land and forest management. <\/span><\/p>\n

Saving Oregon\u2019s Oak Trees <\/b><\/h2>\n

In Oregon, the \u201cTangible Landscape\u201d tool is making a real difference for land managers who are concerned about the spread of Sudden Oak Death. <\/span>The pathogen was introduced in the southwest corner of Oregon in 2001, and rigorous land management practices had kept its spread limited. But in recent years, a newer more aggressive form started attacking. <\/span><\/p>\n

Because Oregon primarily ships timber from a northern port, an aggressive pathogen destroying their trees is a significant threat. <\/span>Using a geospatial participatory modeling approach, <\/span>Gaydos and her colleagues<\/span><\/a> have taken the \u201cTangible Landscape\u201d to Oregon, met with stakeholders, and received feedback on how to best use the technology to address their specific needs. <\/span><\/p>\n

The researchers are currently tweaking the model for a return to Oregon to meet with a broader group of stakeholders who\u2019ll use it to determine how to manage the current pathogen. <\/span><\/p>\n

Gaydos says one of the greatest challenges of this work has been the complexity of the models, \u201cIf we want people to use them, they have to be user friendly.\u201d <\/span><\/p>\n

The team hopes to expand work with stakeholders. With more usable models and more participatory approaches, the chances of buy-in increase, and Gaydos hopes to continue helping stakeholders plan better. She and other members of the research team are also working to make forecasts more real-time, similar to weather forecasts. <\/span><\/p>\n

\u201cWe check the weather in the morning, so we know whether to take a jacket or an umbrella with us,\u201d Gaydos says. \u201cWouldn\u2019t it be nice if land managers could check the pests and pathogen forecast as they make routine management decisions? That\u2019s our goal.\u201d <\/span><\/p>\n

The research team will continue working to that end, involving more and more people in collaborative efforts to address pests and pathogen issues.<\/span><\/p>\n
