    Thinning forests or planting fields? Producer preferences for establishing silvopasture
    Wilkens, Philadelphia; Munsell, John F.; Fike, John H.; Pent, Gabriel J.; Frey, Gregory E.; Addlestone, Benjamin J.; Downing, Adam K. (2021-09-04)
    Silvopasture is the intentional integration of trees, forages, and livestock. Benefits of this agroforestry practice include shade for livestock, nutritious forage, and reduced wind speed in pastures, as well as ecosystem services and tree products. The literature indicate that some livestock producers are interested in silvopasture, but little is known about their establishment preferences and if they vary by demographics or operation type. This study hypothesized that producers are equally interested in planting trees in pastures (planting) and reducing forest canopy and planting forages (thinning) to establish silvopasture, and that the effects of the potential benefits of silvopasture on their preferences are similar. To test these hypotheses, 307 livestock producers in Virginia, United States of America were surveyed about whether they prefer planting or thinning. Producers also were asked about the extent to which potential benefits of silvopasture affect their preferences. Nearly 25% of the 139 respondents (response rate = 45%) were 'very interested' in thinning, compared to 8% for planting. Animal performance and welfare was their primary goal, but forest management and whole-farm productivity also were important. Guidelines are needed for maintaining stand health and productivity when thinning and for improving tree protection and growth in pastures when planting to establish silvopasture.

    X3D Field Trips for Remote Learning
    Polys, Nicholas F.; Meaney, Kathleen; Munsell, John F.; Addlestone, Benjamin J. (ACM, 2021-11-08)
    Combinations of immersive media and graphic portrayals can enable the human subjective sense of Presence. This paper collects our experiences and evaluations from six projects that use Extensible 3D (X3D) interactive graphics to deliver spatial experiences across the WWW. X3D enables the combination of spherical panoramas with 3D models and maps to visually transport users to a specific real location at a specific time. Remote users have access to these worlds through a Web-browser or other immersive device; local users in a CAVE can collaborate with natural physical gestures; . We reflect on the graphical and interactive requirements of these projects and provide guidance for future applications. In the face of physical lock-downs and distancing due to the CoVID pandemic, such platforms illustrate the opportunities and challenges in the design and delivery of spatial visualizations, especially for remote learning.
