Harvard Forest Summer Research Program in Ecology URSSA Survey since 2006
Program Context Since its inception in 1985, when a single undergraduate worked on a study of old-growth forests, the Harvard Forest Summer Research Program in Ecology (HF-SRPE) has developed into a thriving and well-coordinated program that is central to the educational and research mission of the biological field station. With core support since 1993 from a succession of NSF REU Site awards and NSF REU supplements, and with additional funding from Harvard University, HF-SRPE has grown to support 20-30 undergraduate students annually. Students are mentored by principle investigators and senior scientists in conducting research in ecology, soil science, paleoecology, wildlife biology, conservation biology, and atmospheric sciences. The research conducted by our HF-SRPE students contributes substantially to long-term scientific investigations supported by NSF’s Long-Term Ecological Research (LTER) and National Ecological Observatory Network (NEON), NASA Earth System Science Pathfinder (ESSP) – Earth Ventures (EV) programs, The Smithsonian Institution’s ForestGEO network of plots, and Department of Energy’s (DOE) National Institute for Global Environmental Change (NIGEC). The overarching objectives of the program are to: enhance the ability of students to undertake high-quality interdisciplinary research; build teams of researchers in which students bring different strengths to the table, collaborate on cutting-edge projects, and find their own intellectual “voice”; encourage students to link fundamental and applied issues in their research; and cultivate the next generation of ecological scientists and educators that reflects the diversity of backgrounds and experiences of students in the United States. Problem Statement Starting in 2005 the National Science Foundation (NSF), as one of the largest funders of undergraduate research programs, began emphasizing the use of project evaluations to both qualitatively and quantitatively measure the success of REU programs (R
Ecological Momentary Assessment of Family Forest Owners in New England 2016
Family forest owners (FFOs) across the U.S., and particularly in New England, are critically important to the health and future of the nation’s forests. It is important to understand the behavior of FFOs because they in the United States collectively own more forested land than the federal government or any other type of owner, and their actions and decisions will impact the public goods these forests provide. Typical studies of FFO behavior use self-reported survey data; participants are asked to recall past behavior or predict future behavior. These surveys are prone to bias, as it can be difficult to remember when things occur or to accurately predict what one will do in the future. Ecological momentary assessments, used commonly in medicine, are a fresh approach to measuring behavior by querying the subject in real-time. The PING project was designed to reduce this bias and provide a more accurate snapshot of how landowners engage with their land on a short-term basis. Participants in two experimental groups were invited to take part in a month-long survey, where the same questions were sent to them in the method of their choosing (text, via social media, or e-mail) once per week, asking about woodland engagement that week. Participants also took a pre- and post-survey to capture both demographics and feedback on the method. Over 61% of participants completed all 4 surveys and there was no statistically significant difference between the day a participant received their survey. Demographics were consistent with national statistics on woodland owners. A plurality of woodland owners in the study harvested timber for personal use and collected non-timber forest products. Finally, 86% of participants found the method of contact and number of questions reasonable, while 77% found the weekly contact reasonable. A plurality of respondents reported that their answers were typical of a given week, but that the survey question made them think more about their woods than t

Historical and Ecological GIS Data from Manuel F. Correllus State Forest on Martha’s Vineyard 1830-1994
Sand-plain ecosystems are a priority for conservation because they are uncommon, support numerous rare or uncommon plant and animal species, serve as groundwater recharge areas, and are threatened by land development. The 5,200-acre Manuel F. Correllus State Forest, in the central part of Martha’s Vineyard, is part of one of the larger sand-plain ecosystems in New England. This GIS data package was created as part of a study on the history and ecology of Martha’s Vineyard and the state forest as part of an effort to understand sandplain landscapes and make management recommendations for their maintenance.
Candida Pseudoglaebosa Ecology in Sarracenia Purpurea Pitcher Plants at Harvard Forest since 2021
Fungi and bacteria are common members of the microbiomes of carnivorous plants. In the pitcher plant Sarracenia purpurea these microorganisms enter carnivorous pitchers shortly after pitchers develop, and may be relevant for pitcher functioning. We are sampling pitchers repeatedly over several years to better understand the culturable diversity in this habitat, with a focus on the common pitcher yeast Candida pseudoglaebosa and fungi that have the potential to interact with it. C. pseudoglaebosa dominates pitcher plants by arriving early in pitchers, and we are interested in how this yeast’s populations change over time and in response to other pitcher microorganisms. Between 2021 and 2023, we collected pitcher water from Tom Swamp in Harvard Forest and cultured 118 yeast and bacteria colonies from this water. We have found C. pseudoglaebosa and some other yeasts (Papiliotrema, Rhodotorula, and Sporidiobolus); microbial identification is ongoing. We are planning to investigate changes in C. pseudoglaebosa genetic diversity and changes in C. pseudoglaebosa interactions with other pitcher microorganisms over time.
Fern Understory as an Ecological Filter at Harvard Forest 1993-1995
We investigated the role of the fern understory as an ecological filter that influences the organization of the tree seedling bank in New England deciduous forests. The data files below summarize a series of field experiments conducted from 1993 to 1995 evaluating the response of seed germination and seedling growth and survival to experimental understory manipulation. These field studies involved three experimental manipulations of the fern understory: 1) removal of ferns 2) ferns tied back (to remove above-ground shading) 3) ferns left intact (control). These manipulations were established in 180 - 1m2 plots spanning six field sites and 2 different fern species (3 understory manipulations x 2 understory fern species x 6 sites x 5 replicates/site = 180 experimental plots).
Ecology and restoration of montane meadows at Bunchgrass Ridge near the Andrews Experimental Forest, 1999-2013
In a region dominated by coniferous forests, montane meadows contribute greatly to landscape diversity, wildlife habitat, and other important ecological functions and societal values. Throughout the Pacific Northwest, suppression of fire and changes in climate and grazing pressure have led to rapid succession of meadow to forest. Faced by gradual loss of these habitats, land managers are experimenting with tree removal and prescribed fire as tools for restoration. Research at Bunchgrass Ridge explores the history of conifer encroachment, the consequences for meadow vegetation, and the potential to restore native meadows through tree removal and prescribed burning. Spatially explicit reconstructions of the invasion history provide the context for a large-scale restoration experiment testing the efficacy of tree removal, with or without prescribed fire. Measurements from the experimental plots include pre- and post-treatment data on plant species composition for subplots of known invasion history. Data from adjacent, uninvaded meadows serve as targets for assessing restoration success. Our ultimate goal is to determine whether tree removal is sufficient to reverse the effects of encroachment, whether fire is also necessary, and whether the duration or density of invasion pose barriers to meadow reassembly.

Data and R code for “Individual-level variation in reproductive effort in chestnut oak (Quercus montana Willd.) and black oak (Q. velutina Lam.)”, Forest Ecology and Management, 2022
Masting is a population-level reproductive strategy, where individuals synchronize large but intermittent seed production. Despite the high degree of synchrony at the population level, there can be considerable variation in reproduction among individuals (intraspecific variation). Here, we use 18 years of acorn production data from individual chestnut oak and black oak from control and thinned stands, to understand what factors influence individual differences in reproductive effort and variability. We included a variety of tree-level measurements, environmental characteristics, and measurements from tree cores to determine if certain characteristics were associated variations in reproduction. We considered both mean annual acorn production per m2 crown and interannual variation in acorn production (CV) as response variables. We also classified individuals as super producers (i.e., those that consistently produce more acorns than others), good, fair and poor producers (i.e., those that consistently produce less or have a higher number of failure years). In chestnut oak, 14% of the individuals were classified as super producers and contributed 34% of the total acorns, while poor producers made up 35% of the trees and contributed only 16% to total acorn production. In black oak, super producers (14% of the individuals) contributed 31% of total acorns and poor producers (24% of the individuals) contributed only 9% of the acorns. Diameter at breast height (DBH) was the most consistent variable for explaining intraspecific variation in reproductive effort and variability (i.e., larger individuals had higher mean acorn production for both chestnut oak and black oak, and lower CV for black oak). Other variables that influenced reproduction and variation included elevation and clay content for chestnut oak, and slope for black oak. We found no significant effect from the thinning treatment on acorn production. Our results illustrate how tree-level and environmental characte
Ecological Forestry in Western Oregon: A Critical Analysis from Andrews Forest LTER Research, 2014-2015
This work highlights the normative dimensions of “ecological forestry,” a strategy of forest management that uses silviculture to mimic the effects of non-anthropogenic processes of disturbance and succession in order to meet multiple objectives on a single piece of land. An analysis of the arguments made about ecological forestry, both broadly theoretical and pertaining specifically to western Oregon, shows that empirical uncertainties and normative gaps need to be addressed before we can make a clear, well-reasoned decision about whether ecological forestry is a viable and appropriate strategy for forest management and conservation.
Non-trophic interactions amplify kelp harvest-induced biomass oscillations and biomass changes in a kelp forest ecological network model
<p><span>Kelp forests are important marine ecosystems providing habitat for numerous species. Despite over 50 years of mechanical harvesting in the Northeast Atlantic, the indirect impacts of kelp harvesting and associated habitat loss on faunal species within kelp forests remain poorly understood. We investigated the consequences of kelp harvesting by developing an allometric trophic network model for a subtidal Northeast Atlantic kelp forest (dominated by <em>Laminaria</em> <em>hyperborea</em>). Additionally, we designed a novel mechanistic model to explore the non-trophic interactions between kelp and age class 0 Atlantic cod (<em>Gadus</em> <em>morhua</em>) and kelp and European lobster (<em>Homarus</em> <em>gammarus</em>), specifically focusing on the increased survival benefits provided by the kelp habitat. Simulations were conducted over a 50-year period, incorporating harvesting cycles of 2, 5, and 9 years, as well as low and high harvesting intensities. Our findings reveal the complex dynamics resulting from kelp harvesting. The recovery of kelp biomass was observed with 5- and 9-year harvesting cycles, whereas a decline was observed with a 2-year cycle. Furthermore, the non-trophic interaction facilitated a higher pre-harvest biomass for both the European lobster and the Atlantic cod compared to scenarios without this interaction. These results highlight the multitrophic effects of kelp harvesting and emphasize that the recovery of kelp-associated species may not necessarily align with kelp recovery, depending on harvesting intensity and recovery periods. Importantly, our study contributes to a better understanding of the ecological consequences of kelp harvesting and underscores the need for sustainable management practices to mitigate habitat loss in kelp ecosystems.</span></p>
