Among other factors, increased urbanization and parental concern for child safety have decreased time spent by young people in nature in recent decades (Clements, 2004; Pyle, 2003). This loss of connection with nature has been associated with increased anxiety, depression, and obesity, along with reduced learning outcomes, sometimes referred to as nature deficit disorder (Louv, 2005). Efforts to reintroduce youth to play, exploration, and education in natural spaces have shown many benefits ranging from improved emotional development and verbal and math skills in preschoolers (de Chavez et al., 2024), to improved mental health and educational engagement and retention in university students (Boyle et al., 2007; Johnson et al., 2020), and benefits to all age groups in between (Mann et al., 2022). This increased recognition of the benefits of nature-based learning to students’ physical and emotional health and educational outcomes has led to rapidly expanding efforts to get students outside (Mann et al., 2022), including Forest Schools (Cudworth & Lumber, 2021), Outdoor Classroom Day (outdoorclassroomday.com), Wild Learning (discoverwildlearning.com), Green Schoolyards America (greenschoolyards.com), and Adventure Education (Hattie et al., 1997).

University arboretums represent managed, natural spaces that support education, conservation, and research by preserving ecosystems such as wetlands, prairies, and forests. A functioning arboretum offers active learning and hands-on research opportunities for students and the community, serving as a living classroom where people can study plants, wildlife, ecology, and land management. Universities often share research generated at public events to educate students and the public, thus giving back to the communities they serve (Meyer et al., 2010). Arboretums provide a unique combination of research, education, and opportunities for outdoor activities that cannot be duplicated in municipal parks or private properties in most communities.

The R.A. Stranahan Arboretum (Figure 1) is located 5 km northwest of the University of Toledo (Toledo, OH, USA) main campus in an affluent suburban residential area, and includes a 19-ha, fenced-in space encompassing a native forest with glacial sand dunes, multiple wetlands, a stream flowing through a forested ravine, open grassy areas, some native prairie, and an extensive collection of trees from temperate regions of the world. The land was donated to the university in 1964 for the purpose of providing an active center for interdisciplinary research, learning, and extensive community engagement including public festivals, private events, and science programs for local schools. The Arboretum has played an important role in supporting student success by offering outdoor classroom and laboratory space for undergraduate and graduate courses, particularly in ecology, environmental science, and geology, in which students monitor groundwater, wildlife, and study the diverse ecosystems including wetlands, ponds, prairies, and forests. Many students value arboretums once they understand how natural areas support learning experiences and field-based research, as students prefer to visit campus areas with abundant green spaces (Aghabozorgi et al., 2025). Previous studies have also shown that exposure to green spaces and outdoor learning environments benefit student well-being, significantly improving student mental health by lowering stress and anxiety, all of which contribute to enhanced academic performance (Wang et al., 2023).

U.S. institutions of higher learning have experienced a decade of declining undergraduate enrollment, exacerbated by the COVID-19 pandemic, which has constrained budgets, and forced difficult financial decisions (WCET, 2023). Universities in such circumstances are under extraordinary pressure to stabilize enrollment with ever-shrinking tuition revenues, including increased incentivization to provide unique, student-centric facilities and resources. Undergraduate enrollment at the University of Toledo declined considerably more (-27%) than the national average (-15%) from 2010 to 2021, followed by additional decline of 13% through 2025 during a national enrollment rebound of ~5% (NSC Research Center, 2025). Universities aware of the values and demands of current and potential students are positioned to

However, the current enrollment crisis has occurred within an academic culture that already viewed expenditures on environmental and conservation related programs, including biological field stations, as non-essential (Jaramillo et al., 2025), calling into question how a university perceives the benefits of owned natural spaces used for environmental research, education, and student well-being.

Some research stations are stable and expanding with institutional support (e.g., University of Cincinnati Field Center), or despite budgetary constraints are newly created through donor support (e.g., Kent State University’s New Outdoor Biological Research Station [Kent State, 2025]), and some are self-sufficient with sales and donations (e.g., Chadwick Arboretum, Ohio State University). However, the benefits of facilities at off-campus locations are generally underappreciated (Kimbrough, 2024) and are underfunded (Jaramillo et al., 2025), especially remote field stations (Eppley et al., 2024; NRC, 2014), and some are being sold-off (e.g., Hofmann forest, North Carolina State University). Regardless of its apparent value, a series of resource realignments and administrative priority changes have disadvantaged the Stranahan Arboretum for decades, and despite the current climate of fast-increasing value in university-owned natural spaces, the Arboretum remains without a dedicated budget, maintenance personnel, or other administrative support. The lack of resources, followed by closure during the COVID-19 pandemic, and deed restrictions that prohibit sale of the property, left the University of Toledo’s outdoor natural classroom and laboratory with an uncertain future. A difficult aspect of budgetary belt-tightening is predicting the potential value lost when a program or facility is cut or shut down. If the short-term savings resulting from the cut are relatively small compared to greater long-term losses, then not only does the university incur a loss of a valuable resource, but also the exacerbation of enrollment and budgetary issues. Alternatively, a modest investment in an entity, although difficult in the short-term, can allow a realization of its potential as a component of long-term institutional stability and growth.

Administrative decision makers need all the information they can get about the values of their current and prospective students. Understanding nuanced student values is especially needed at the University of Toledo (Toledo, OH, USA), where students typically rate courses and professors highly (Niche, 2026), yet also rank the institution behind all others in Ohio when asked if they would recommend their university to students (Wall Street Journal, 2025). Historically, University of Toledo administrators understood the value of the Stranahan Arboretum, with one associate vice president in 1994, writing,

More than three decades of declining support and activity later, that institutional knowledge has faded, and it is currently unclear how decisions affecting the Arboretum would impact student education, well-being, and connection to the university. An apparent lack of student awareness could be interpreted by decision-makers as low student priority, justifying divestment with minimal concern for student impact. However, the Arboretum is absent from university maps, strategic plans, sustainability initiatives, and is minimally featured on the university website, raising the question of whether students are truly disengaged or simply unaware of its existence. A 2022 informal survey of 46 students in the university’s general ecology course (EEES 3050) found only 11 (24%) students were aware of the Stranahan Arboretum. While that show-of-hands survey suggested a lack of awareness among a subset of undergraduate students, the value of the Arboretum to the students was unmeasured, and important data critical for administrative decision-makers remain unavailable.

In an effort to formally and comprehensively assess student awareness of the Arboretum, and more importantly, their desire to visit, volunteer for, and maintain the vital functions at the Arboretum, we surveyed the University of Toledo undergraduate student body, as a component of our senior environmental capstone course (EEES 4970). We also assessed how students valued the Arboretum by asking about their willingness to pay, a standard measure in conservation science that uses a hypothetical market approach to determine the economic value of a habitat, species, or ecosystem service. In this case we assessed whether students would support a nominal student fee to fund operations at the Arboretum.

The aim of this study was to assess the awareness, interest, and willingness among undergraduate students at a single university to support a university-owned natural space that is intended for environmental research, education, and public engagement, but is generally neglected and under consideration for divestment by the university.

Four of us (KD, PD, LP, and SF) developed a survey comprising 1 prompt and 10 questions for undergraduate students enrolled at the University of Toledo during Fall semester, 2025 in consultation with our mentor, WVS. No other faculty administrators or students were informed or consulted during survey development. Prior to deployment, the survey was approved by both the university Survey Committee and Institutional Review Board (302384-UT). The survey was created and disseminated in Microsoft Forms to all 10,810 currently enrolled undergraduate students via their university email addresses on 3 November 2025. The survey was anonymous, with only one prompt (“select your academic college”) providing any identifying information. Due to time constraints, students had one week to complete the survey, and no follow-up emails were sent.

The survey was titled “Stranahan Arboretum interest survey,” and began with the following paragraph:

The survey prompt and questions were as follows:

The prompt to identify each student’s academic college was intended to allow us to assess whether the responses were representative of the entire student body or biased toward specific groups. The questions were designed to address specific points to inform decision-makers at the university about how and why students want or do not want to use or support the arboretum. Question 1 and question 2 were intended to assess student awareness of the arboretum as a university property. Question 3 was a stand-alone assessment of student interest in taking classes and attending events at the arboretum. Questions 4, 5, 6, 8, and 9 were intended to assess reasons other than classes and organized events for which students would visit, how often they would visit, and what factors might limit their visitation of the arboretum. Question 7 and question 10 were assessments of whether students would support the arboretum financially and through volunteerism, respectively.

We present all survey results as numerical values and percentages. To test whether responses were proportional to enrollment in each academic college we used linear regression. For questions gauging interest in classes/events, 7 (willingness to pay), and 10 (interest in volunteering), we used χ² tests of independence to assess whether student answers differed among academic colleges. Tests were run in R (version 4.5.1 [R Core Team, 2025]) and we considered differences statistically significant at α = 0.05.

The survey was completed by 470 students for a response rate of 4.3%. However, not all respondents answered all questions, so sample sizes ranged from 458 to 470 for each question. Response rates were limited, as expected, by our narrow response window (one week) and our inability to send follow-up messages. Similar surveys of academic institutions with relatively low response rates provide reliable, important insights (e.g., Silverwood et al., 2026), so we are confident that our results are representative of student opinion at the university. Of the seven academic colleges represented in our survey, responses from university college were disproportionally low compared to enrollment. We are unsure if the low response rate reflects minimal interest among the part-time students and those with undeclared majors who tend to populate the college, or if the students affiliated themselves with a different college in our survey. The sample size of students responding to the survey was representative of all other academic colleges across campus (Figure 2), with college-level response rates proportional to college enrollments (R² = 0.64, p = 0.03).

Of University of Toledo students, 61% were aware of the Arboretum and 39% reported having visited the Arboretum. A large percentage of students (82%) reported interest in taking classes and attending events at the Arboretum. This result varied significantly among colleges (χ² = 20.1, df = 7, p = 0.004), ranging from the college of business (66% yes) to the college of pharmacy and pharmaceutical sciences and the college of natural sciences and mathematics (both 93% yes).

A similarly high percentage (83%) of students answered yes or maybe regarding willingness to volunteer their time in support of the Arboretum (Figure 3), and that interest was similar across academic colleges (χ² = 10.5, df = 7, p = 0.16). In addition, 78% of students would support a new student fee to fund Arboretum operations (Figure 4), and that support was similar across academic colleges (χ² = 11.6, df = 7, p = 0.12).

Results from question 3 indicated that 82% of students desire classes and organized events at the arboretum. Additionally, 67% of students would visit the Arboretum at least once per month, with 7% wanting to visit daily, and at all daily time windows offered on the survey. Students were asked to elaborate on the survey if they responded “other” regarding visitation frequency. Responses included statements ranging from “I don’t know what it is” to “often during warmer months.” Separately from the 82% of students desiring classes and organized events, at least 50% of students identified each of the following as motivational reasons to visit the Arboretum: relaxation and scenic walks, festivals, exercise, and artistic activities. The majority (72%) of students also identified the inclusion of walking trails and restrooms as high- priority amenities. The primary issue students identified as preventing them from visiting the Arboretum was lack of awareness of events (85%), with smaller percentages of students (< 25%) noting distance and transportation as limiting factors. Two students referenced the university prohibiting access preventing them from visiting the Arboretum.

University arboretums provide significant environmental, educational, and mental health benefits to campus and local communities including roles as living research laboratories and spaces beneficial for mental health (Hipp et al., 2016; McFarland et al., 2008; Rakow & Ibes, 2022). The University of Toledo’s Stranahan Arboretum is an untapped resource in a time of great institutional need. Following years of neglect, faculty, staff, students, Arboretum neighbors, and other community members have volunteered to revitalize the Arboretum, resulting in revived research activity, newly developed courses that utilize the Arboretum, and renewed public and alumni interest in supporting and accessing the Arboretum. Despite this progress, in fall 2025, divestment plans were announced and student events, student internships and volunteer opportunities, and public access at the Arboretum were prohibited.

Our study showed that undergraduate students at the University of Toledo overwhelmingly value and desire to support, visit, and use the university’s long-neglected Stranahan Arboretum. Our results indicate a substantial disconnect between students, who support a university-owned natural space intended for environmental research, teaching, community engagement, and experiences in nature, and an administration that fails to value a critical resource. Preservation of natural campus areas often conflicts with campus development plans, as administrators prioritize potential profit centers over maintaining green spaces, often evidenced in campus revitalization efforts (e.g., MSU Facilities Services, 2008). As a result, natural areas may suffer from a lack of resources compared to highly managed, prized spaces (like central malls and lawns), resulting in reduced visibility or decreased attractiveness to students (Jones, 2010). The disconnect between student values and those of administrations is especially puzzling given that learning in natural settings can motivate students who struggle in traditional, indoor classrooms (Dettweiler et al., 2015), and mental-health restoration is a primary driver for 76% of visits to university-owned botanical gardens (Jaramillo et al., 2025). Furthermore, student involvement in outdoor-related programs is linked to increased retention and timely graduation (Michael et al., 2017).

Student surveys frequently find that significant percentages of students are unaware of available services or activities (Flaherty, 2023). However, our survey showed that more than 60% of current students are aware of the Arboretum and 39% report having visited the property. This visitation result is consistent with Arboretum records for attendance in courses, events, and volunteer opportunities (~4,000 total; HMS unpublished data) from 2022-2025 under volunteer leadership. The awareness result (61%) represents a strong turnaround from three years earlier, when only 24% of students in the university’s general ecology course (i.e., students most likely to be aware) knew that the university owned an arboretum. Learning in nature is a positive experience for students, as course evaluations (curriculum and course materials) (Benfield et al., 2015) and overall interest in school (Becker et al., 2017) are demonstrably greater when students are educated in an outdoor setting. Therefore, after three years of classes, research activity, volunteer opportunities, and small student gatherings and events, we expected at least modest support among students for the Arboretum. However, survey results revealed that student support was overwhelming, as 82% of students reported interest in attending classes and events, 83% would consider volunteering to help the Arboretum, and 78% would support a new student fee to fund Arboretum operations. Even the least positive response from any academic college to any of the survey questions (college of business) had 66% of students respond positively regarding interest in Arboretum classes and events. That 78% of undergraduate students would support a new student fee is a notably high willingness to pay value among conservation-related surveys. This is especially noteworthy at the University of Toledo, where students come from a broad range of economic backgrounds and more than one-third are first-generation college students (utoledo.edu).

While the vast majority of the student population is aware of the Arboretum, 85% of students cited being unaware of Arboretum events as the primary factor preventing them from visiting the facility. It follows that limited visitation likely results in a lack of awareness amongst students of the university’s current prohibition on events, volunteering, and public access to the property. As a result of these limitations, awareness and use of the Arboretum is entirely dependent on word-of-mouth and volunteer efforts by faculty, staff, students, and community members. The university’s current restriction of Arboretum activities to only those involving formal courses and research supports the students’ greatest desire of attending classes at the Arboretum, but denies the students’ other wishes, which include scenic walks, festivals, exercise, and artistic activities. Two-thirds of the students responding to our survey would prefer to visit the Arboretum regularly, at least once per month, while 7% of respondents were interested in visiting daily. This desired visitation volume is comparable to the volumes noted for seemingly more popular facilities, like campus recreation centers, which attract up to 75% of students (Forrester, 2014). An important factor of our study is understanding that students who wish to visit the Arboretum are required to actively (vs. passively) visit the facility, as it is located away from the main campus. Results from previous studies measuring student utilization of green space showed that 33% were highly active green spaces users (Holt et al., 2019). Therefore, the 67% of University of Toledo students who desire to use the Stranahan Arboretum regularly represents a remarkable proportion of would-be active users.

Perpetual prioritization of programs and facilities based on current activity rates can lead to detrimental institutional inertia, and failure to realize the revenue producing potential of long-neglected entities. Our results emphasize that the limited activity at the Stranahan Arboretum is not driven by a lack of interest or desire from students. This administrative view of the Arboretum as a low-value facility that lacks faculty and student interest, is thus self-fulfilling and unfortunately, self-destructive, as it precludes the administration from realizing the revenue-producing potential of the facility. It is clear that despite this circular dilemma, the level of awareness and positive opinions among student concerning the Stranahan Arboretum present an opportunity for the University of Toledo to make an informed, cost-effective priority realignment in a time of need for low-cost strategies that benefit student recruitment and retention. Support for the Arboretum represents a commitment to environmental research, education, outreach, and experiences desired by students. In alignment with the results of the current study, previous studies have shown that college students value and use green spaces on their campuses (Speake et al., 2013), and the benefits of natural areas extend beyond recreational uses. Specifically, short visits to campus green spaces effectively relieve student stress (Ibes et al., 2018), while student outlook can improve significantly following 10-20 minutes in a natural setting (Ibes & Forestell, 2022). Given the increasing enrollment trends in environmental science programs across the U.S. (Vincent, 2009), the overwhelming concern for environmental issues among students of all majors (Edmundson, 2024), and the corroboration of those values among students in our survey, the University of Toledo is positioned for a return on modest investment if Stranahan Arboretum personnel and operations are supported.
