“…Although effective, using herbicides can also have negative consequences for native plants. In the study previously mentioned, Lanzer et al (2017) found a five-fold increase in mortality of native white pine plants near buckthorn treated with herbicide. Although management is necessary, it is important to note that any disturbance to the natural environment, whether that be cutting, burning, or spraying, can damage surrounding natives and expose the area to future invasions (Usher 1987).…”

“…Buckthorn forms dense thickets in both open areas and forest understories due to its rapid growth and early leaf-out (Webster et al 2006, Lanzer et al 2017. Buckthorn thickets are associated with reduced native plant seedling density and species richness (Frappier et al 2003a).…”

“…Even seedlings that were established in a buckthorn thicket, such as red oak (Quercus rubra) and sugar maple (Acer saccharum), experienced reduced height and diameter measurements compared to those grown in the absence of buckthorn (Hamelin et al 2016). Lee et al (2016) and Lanzer et al (2017) observed taller and more productive eastern white pine (Pinus strobus) seedlings and saplings where buckthorn had been removed.…”

“…Prescribed burning increased buckthorn re-sprouting two years after treatment (Nagel et al 2008). Another study found that cut stems sprouted more vigorously than those that were cut and sprayed with herbicide (Lanzer et al 2017), indicating that cutting alone is not sufficient to eradicate buckthorn from an area. Nagel et al (2008) conducted an experiment to test the effectiveness of different removal methods of buckthorn.…”

not have been able to get off the ground. First, I would like to thank my thesis advisor, Dr. Thomas Lee, for his invaluable insight, guidance, and motivation throughout both this project and my graduate career. It was through Dr. Lee's passion for the environment that I cultivated mine further, and I couldn't be more grateful. I would also like to thank my committee members, Dr. Mark Ducey and Michael Simmons, for the level of effort they provided for this project. Their assistance allowed for me to develop this project into one that I am proud to have completed. There is not enough praise that I could give to my research assistants, Hannah McCarthy and Riley Bibaud, to account for my level of appreciation for them. Their devotion to this research and their drive in the field was unmatched, and I couldn't have asked for a stronger team. It was because of their positive energy that the field season was a success. I would also like to thank Jenna O'del for her assistance in the field and Nick Warren for his generosity in lending drying ovens. I am also grateful to Steve Eisenhaure for his assistance throughout the summer by providing accessibility to my sites. I would like to thank Suzanne Hebert, Thomas Buob, and Hailee Whitesel for their handling of my many soil samples.

“…Large‐extent land cover maps generally do not include species‐level classes, though such information would be useful in many contexts. For example, in southern New England, USA, eastern white pine ( Pinus strobus ) is both an important timber species and a preferred habitat type for the invasive shrub glossy buckthorn ( Frangula alnus ; Burnham and Lee 2010, Lee and Thompson 2012, Lanzer et al 2017). Any regional ecological models involving timber operations or invasive species management would be improved by incorporating more detailed information on the distribution of white pine forests (Szewczyk et al 2019).…”

Ecological models are constrained by the availability of high‐quality data at biologically appropriate resolutions and extents. Modeling a species' affinity or aversion with a particular land cover class requires data detailing that class across the full study area. Data sets with detailed legends (i.e., high thematic resolution) and/or high accuracy often sacrifice geographic extent, while large‐area data sets often compromise on the number of classes and local accuracy. Consequently, ecologists must often restrict their study extent to match that of the more precise data set, or ignore potentially key land cover associations to study a larger area. We introduce a hierarchical Bayesian model to capitalize on the thematic resolution and accuracy of a regional land cover data set, and on the geographic breadth of a large area land cover data set. For the full extent (i.e., beyond the regional data set), the model predicts systematic discrepancies of the large‐area data set with the regional data set, and divides an aggregated class into two more specific classes detailed by the regional data set. We illustrate the application of our model for mapping eastern white pine (Pinus strobus) forests, an important timber species that also provides habitat for an invasive shrub in the northeastern United States. We use the National Land Cover Database (NLCD), which covers the full study area but includes only generalized forest classes, and the NH GRANIT land cover data set, which maps White Pine Forest and has high accuracy, but only exists within New Hampshire. We evaluate the model at coarse (20 km2) and fine (2 km2) resolutions, with and without spatial random effects. The hierarchical model produced improved maps of compositional land cover for the full extent, reducing inaccuracy relative to NLCD while partitioning a White Pine Forest class out of the Evergreen Forest class. Accuracy was higher with spatial random effects and at the coarse resolution. All models improved upon simply partitioning Evergreen Forest in NLCD based on the predicted distribution of white pine. This flexible statistical method helps ecologists leverage localized mapping efforts to expand models of species distributions, population dynamics, and management strategies beyond the political boundaries that frequently delineate land cover data sets.
