• Abstract:

  Forest insects have significant direct impacts on forest ecosystems; they are also generating new risks, uncertainties, and opportunities for forest landowners. Our research objective is to understand: (1) whether and how insect infestations are shifting land-use regimes in New England by altering human decision-making, (2) how these changes to human decisions may affect regional forest ecosystems and the provisioning of select ecosystem services, and (3) how subsequent changes to forest ecosystems, in turn, affect landowners.

  The dataset is a result of gathering information from a random sample of family forest owners (FFOs) in the Connecticut River Watershed; FFOs own approximately half of the private forestland in the region. We collected information on characteristics and perceptions of these FFOs as well as their intentions for their land if faced with the presence or threat of invasive forest insects. To better understand FFO intentions, contingent behavior questions populate the conjoint analysis format of the questionnaire. These are the foundational data that form our further efforts to simulate the impacts of insect dynamics and landowner behavior on regional forest ecosystems, including forest carbon stores, forest structure and composition, and timber yields. One of our overarching hypotheses is that forest land-use change in response to insects will have greater near-term ecological consequences than climate change or insects by themselves.

• Methods:

  Survey Instrument

  We developed a survey instrument to understand how family forest owners perceive forest insect pests and how those perceptions influence their land use and land management decisions in response imminent or ongoing insect infestations. The survey instrument contains questions related to: property ownership, forest management objectives, forest management activities, hypothetical forest insect invasion scenarios, perceptions about forest insect pests and management responses, forest insect pest awareness, knowledge and experience, and demographic questions.

  To assess likely FFO response to forest insect pests, we constructed a series of contingent behavior questions based on four key forest insect pest attributes at varying levels: (i) arrival time, how virulent or damaging the forest insect pest is, including (ii) tree mortality percentage and (iii) time until 100% tree mortality, and (iv) value of timber loss. Table 1, Conjoint analysis scenarios of forest insect pest attributes by survey version, is attached as file hf326-03-table1.pdf. We selected these attributes to reflect characteristics of the main forest insect pests in the northeast. Also attached is one version of the survey, hf326-02-survey.pdf.

  Study Area

  Our study area consists of the forests of the Connecticut River Valley watershed in the northeastern United States, a region which has been the focus of intensive ecological and social studies that provide a solid foundation and leveraged resources, including models, proven methods, and data.

  Sample Selection

  Samples were drawn from available electronic tax records “Grand Lists” (NH and VT) and state geospatial resources (MA and CT). A stratified random sample of landowners were sampled within 6 regions comprising the study area (Massachusetts, Connecticut, Northern and Southern New Hampshire, Northern and Southern Vermont) owning fewer than or equal to 49 acres and more than or equal to 50 acres.

  Survey Administration

  We followed a modified, four-wave Dillman, Smyth and Christian (2014) total design method. The four-wave mailing was sent over a 5-week period. The survey was mailed to 2,000 randomly selected family forest owners in the Connecticut River Valley watershed owning 10 or more acres.

  The initial, pre-notice postcard was mailed on June 16, 2017. The initial survey package (cover letter, survey instrument, BRE) was mailed on June 23, 2017. The thank you / reminder postcards were sent on June 30, 2017. A final survey package was mailed on July 14, 2017. The survey cooperation rate was 37% (n = 696). Based on analysis of follow-up telephone calls, we detected no evidence of nonresponse biases. We imputed item nonresponse values using a random forests approach (sensu Stekhoven and Buhlmann, 2012).
