Citizen Science as an Ecosystem of Engagement: Implications for Learning and Broadening Participation.

The bulk of research on citizen science participants is project centric, based on an assumption that volunteers experience a single project. Contrary to this assumption, survey responses (n = 3894) and digital trace data (n = 3649) from volunteers, who collectively engaged in 1126 unique projects, revealed that multiproject participation was the norm. Only 23% of volunteers were singletons (who participated in only one project). The remaining multiproject participants were split evenly between discipline specialists (39%) and discipline spanners (38% joined projects with different disciplinary topics) and unevenly between mode specialists (52%) and mode spanners (25% participated in online and offline projects). Public engagement was narrow: The multiproject participants were eight times more likely to be White and five times more likely to hold advanced degrees than the general population. We propose a volunteer-centric framework that explores how the dynamic accumulation of experiences in a project ecosystem can support broad learning objectives and inclusive citizen science.

Greenspace and park use associated with less emotional distress among college students in the United States during the COVID-19 pandemic.

The COVID-19 pandemic has negatively affected many people's psychological health. Impacts may be particularly severe among socially vulnerable populations such as college students, a group predisposed to mental health problems. Outdoor recreation and visits to greenspaces such as parks offer promising pathways for addressing the mental health challenges associated with COVID-19. During the early stages of the pandemic (March-May 2020), we surveyed 1280 college students at four large public universities across the United States (U.S.) to assess how, and why, outdoor recreation and park use changed since the emergence of COVID-19. We also measured students' self-reported levels of emotional distress (a proxy for psychological health) and assessed potential demographic and contextual correlates of distress, including county-level per capita park area and greenness, using generalized linear models. We found that 67% of students reported limiting outdoor activities and 54% reported reducing park use during the pandemic. Students who reduced their use of outdoor spaces cited structural reasons (e.g., lockdowns), concerns about viral transmission, and negative emotions that obstructed active lifestyles. Students who maintained pre-pandemic park use levels expressed a desire to be outdoors in nature, often with the explicit goal of improving mental and physical health. Emotional distress among students was widespread. Models showed higher levels of emotional distress were associated with reducing park use during the pandemic and residing in counties with a smaller area of parks per capita. This study of U.S. college students supports the value of park-based recreation as a health promotion strategy for diverse populations of young adults during a time of crisis.

Citizen science as a tool for enhancing recreation research in protected areas: Applications and opportunities.

As the popularity of nature-based recreation and tourism grows, protected area (PA) managers around the world are faced with escalating monitoring and management challenges across spatial and temporal scales. Citizen science, an emerging research approach which involves active public participation and collaboration with scientists in the scientific process, is an innovative tool that could help managers address these challenges. This study applied the Preferred Reporting Items for Systematic Review Recommendations (PRISMA) protocol to review published studies that utilized citizen science methods in recreation research, examining the extent and nature of such applications and identifying future opportunities. We identified 20 peer-reviewed journal articles from the Web of Science, most of which were published since 2015. These studies utilized different citizen science approaches to examine recreation patterns, behaviors, and impacts in terrestrial and marine PAs. We found that citizen science was used most often in marine PAs, with specialized recreationists (e.g., SCUBA divers) as the most frequent contributors. The types of volunteers recruited differed by their sources (i.e., general public, recreation specialists, and organizational affiliates) and roles (i.e., volunteers as agents of data collection and volunteers as research subjects), with innovative technology (e.g., participatory GIS) creating new engagement opportunities. Despite these benefits, the accuracy and reliability of citizen science data remain important considerations for managers. Our review demonstrates how citizen science can inform management and enhance public participation in PA stewardship activities, and it reveals the need for more research to explore applications of citizen science in different recreation contexts.

Nature-based Pathways to Health Promotion: The Value of Parks and Greenspace.

The built environment is a key social determinant of health. Exposure to parks and greenspace can improve physical and mental health and provide other benefits that enhance well-being. Programs and initiatives that capitalize on nature-based opportunities offer health care providers with a cost-effective alternative for upstream health promotion.

"Messy transitions": Students' perspectives on the impacts of the COVID-19 pandemic on higher education.

The COVID-19 pandemic affected every area of students' lives, especially their education. Limited research has explored students' experiences during the pandemic. This study documents how students across seven United States universities viewed the impact of the COVID-19 pandemic on their educational experiences and how these students reacted to these impacts. We present qualitative data from an online survey conducted between March and May 2020 that resulted in 1267 respondents with relevant data. Conventional content analysis with an inductive approach was used to analyze open-ended responses to the question, "We are interested in the ways that the coronavirus (COVID-19) pandemic has changed how you feel and behave. What are the first three ways that come to mind?" Six categories emerged from the data: changes in instruction delivery mode, changes in schedule and everyday life, increased technology use, decreased academic opportunities and resources, negative reaction to the changes in higher education, and positive reactions to changes in higher education. Among our recommendations for practice are personalized approaches to material delivery and evaluation, synchronous classes and opportunities to connect with professors and students, and convenient support services.

Local Government Capacity to Respond to Environmental Change: Insights from Towns in New York State.

Local governments attempting to respond to environmental change face an array of challenges. To better understand policy responses and factors influencing local government capacity to respond to environmental change, we studied three environmental issues affecting rural or peri-urban towns in different regions of New York State: climate change in the Adirondacks (n = 63 towns), loss of open space due to residential/commercial development in the Hudson Valley (n = 50), and natural gas development in the Southern Tier (n = 62). Our analysis focused on towns' progression through three key stages of the environmental policy process (issue awareness and salience, common goals and agenda setting, policy development and implementation) and the factors that affect this progression and overall capacity for environmental governance. We found that-when compared to towns addressing open space development and natural gas development-towns confronted with climate change were at a much earlier stage in the policy process and were generally less likely to display the essential resources, social support, and political legitimacy needed for an effective policy response. Social capital cultivated through collaboration and networking was strongly associated with towns' policy response across all regions and could help municipalities overcome omnipresent resource constraints. By comparing and contrasting municipal responses to each issue, this study highlights the processes and factors influencing local government capacity to address a range of environmental changes across diverse management contexts.

Place attachment mediates links between pro-environmental attitudes and behaviors among visitors to Mt. Bukhan National Park, South Korea.

Introduction: Efforts to understand visitors' participation in pro-environmental behaviors (PEB) are important for protected area management. Previous research in nature-based recreation settings suggests environmental attitudes may affect PEB, and that these relationships might be mediated by different dimensions of place attachment (place identity and place dependence). Methods: We used structural equation modeling to test the mediating effect of hikers' place attachment in the relationship between environmental attitudes and PEBs that occur within (on-site) and outside a protected area (off-site): Mt. Bukhan National Park in South Korea. Results: Results showed that cognitive (environmental knowledge) and affective (environmental sensitivity) components of environmental attitudes were significant predictors for place attachment. Place identity was linked to off-site PEB, while place dependence was a key antecedent for both off-site and on-site PEBs. Discussion: Our findings could help researchers and practitioners better understand how place attachment forms and how it can impact outdoor recreationists' behavior, ultimately helping to promote PEBs and facilitate sustainable management goals.

Nature exposure and mental health during the COVID-19 pandemic: A Navigation Guide systematic review with meta-analysis.

Prior reviews have highlighted that nature exposure was a valuable coping strategy enhancing mental health during the COVID-19 pandemic. However, no existing reviews have determined the quality of evidence and risk of bias of the empirical studies supporting this claim. To address this gap, we employed a Navigation Guide systematic review and meta-analysis approach to investigate associations between nature exposure and mental health during the pandemic. Searches in PubMed, Web of Science, Scopus, CINAHL, and PsycInfo retrieved relevant articles published between January 1, 2020, and March 4, 2024. We used the Navigation Guide methodology to assess the risk of bias and Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) assessments to evaluate the overall quality of evidence. Our search retrieved 113 studies that met the inclusion criteria and reported diverse types of exposure, including nature availability, nature visit frequency, green space accessibility, and green space type, alongside associations with 12 mental health outcomes. Meta-analyses found access to gardens was associated with lower odds of depression [(Pooled odds ratio [OR] = 0.71, 95%CI = 0.61, 0.82), I2 = 0%, n = 3] and anxiety [(Pooled OR = 0.73, 95%CI = 0.63, 0.84), I2 = 0%, n = 3]. Increased time in green spaces was associated with lower level of stress [(Pooled Corr = -0.11, 95%CI = -0.17, -0.05), I2 = 0%, n = 2]. Higher frequency of visits to nature was associated with improved mental well-being [(Pooled standardized beta = 0.10, 95%CI = 0.07, 0.14), I2 = 0%, n = 2] and general mental health [(Pooled standardized beta = 0.11, 95%CI = 0.03-0.38), I2 = 82%, n = 2]. However, the number of pooled studies was small and the overall quality of evidence was "very low" for all outcomes, and high levels of bias were observed (26% of studies had high, 71% probably high). Nonetheless, given the trends in the results, nature-based solutions emphasizing exposure to gardens and green spaces near the home may have promoted psychological resilience during this public health crisis.

The complex relationship between greenspace and well-being in children with and without autism.

Greenspace (defined here as canopy coverage) positively correlates with improved well-being in typically developing individuals, but this relationship has not been established in children with autism spectrum disorder (ASD). To investigate this relationship, the current study merged data from the National Survey of Children's Health (2012) with the National Land Cover Database. Across typically developing children, children with ASD, and non-autistic children with special healthcare needs (CSHCN), greenspace unexpectedly negatively correlated with well-being. Further, compared with typically developing children, children with ASD or CSHCN status had lower well-being. Interestingly, typically developing children with conduct problems displayed an unexpected negative relationship (i.e. as greenspace increased whereas well-being decreased), though those without conduct problems showed no relationship. Children with ASD displayed no relationship between greenspace independent of conduct problems. CSHCN displayed non-significant trends suggesting mild positive relationships between greenspace and well-being. These data indicate the relationship between greenspace and well-being is more complex than expected and may depend on the diagnostic traits of the population studied.

Greenness and equity: Complex connections between intra-neighborhood contexts and residential tree planting implementation.

Associations between neighborhood greenness and socioeconomic status (SES) are established, yet intra-neighborhood context and SES-related barriers to tree planting remain unclear. Large-scale tree planting implementation efforts are increasingly common and can improve human health, strengthen climate adaptation, and ameliorate environmental inequities. Yet, these efforts may be ineffective without in-depth understanding of local SES inequities and barriers to residential planting. We recruited 636 residents within and surrounding the Oakdale Neighborhood of Louisville, Kentucky, USA, and evaluated associations of individual and neighborhood-level sociodemographic indicators with greenness levels at multiple scales. We offered no-cost residential tree planting and maintenance to residents within a subsection of the neighborhood and examined associations of these sociodemographic indicators plus baseline greenness levels with tree planting adoption among 215 eligible participants. We observed positive associations of income with Normalized Difference Vegetation Index (NDVI) and leaf area index (LAI) within all radii around homes, and within yards of residents, that varied in strength. There were stronger associations of income with NDVI in front yards but LAI in back yards. Among Participants of Color, associations between income and NDVI were stronger than with Whites and exhibited no association with LAI. Tree planting uptake was not associated with income, education, race, nor employment status, but was positively associated with lot size, home value, lower population density, and area greenness. Our findings reveal significant complexity of intra-neighborhood associations between SES and greenness that could help shape future research and equitable greening implementation. Results show that previously documented links between SES and greenspace at large scales extend to residents' yards, highlighting opportunities to redress greenness inequities on private property. Our analysis found that uptake of no-cost residential planting and maintenance was nearly equal across SES groups but did not redress greenness inequity. To inform equitable greening, further research is needed to evaluate culture, norms, perceptions, and values affecting tree planting acceptance among low-SES residents.

Beyond "bluespace" and "greenspace": A narrative review of possible health benefits from exposure to other natural landscapes.

Numerous studies have highlighted the physical and mental health benefits of contact with nature, typically in landscapes characterized by plants (i.e., "greenspace") and water (i.e., "bluespace"). However, natural landscapes are not always green or blue, and the effects of other landscapes are worth attention. This narrative review attempts to overcome this limitation of past research. Rather than focusing on colors, we propose that natural landscapes are composed of at least one of three components: (1) plants (e.g., trees, flowering plants, grasses, sedges, mosses, ferns, and algae), (2) water (e.g., rivers, canals, lakes, and oceans), and/or (3) rocks and minerals, including soil. Landscapes not dominated by plants or liquid-state water include those with abundant solid-state water (e.g., polar spaces) and rocks or minerals (e.g., deserts and caves). Possible health benefits of solid-state water or rock/mineral dominated landscapes include both shorter-term (e.g., viewing images) and longer-term (e.g., living in these landscapes) exposure durations. Reported benefits span improved emotional and mental states and medical treatment resources for respiratory conditions and allergies. Mechanisms underlying the health benefits of exposure consist of commonly discussed theories in the "greenspace" and "bluespace" literature (i.e., instoration and restoration) as well as less discussed pathways in that literature (i.e., post-traumatic growth, self-determination, supportive environment theory, and place attachment). This is the first review to draw attention to the potential salutogenic value of natural landscapes beyond "greenspace" and "bluespace." It is also among the first to highlight the limitations and confusion that result from classifying natural landscapes using color. Since the extant literature on natural landscapes - beyond those with abundant plants or liquid-state water - is limited in regard to quantity and quality, additional research is needed to understand their restorative potential and therapeutic possibilities.

Political polarization of conservation issues in the era of COVID-19: An examination of partisan perspectives and priorities in the United States.

As a zoonotic disease with unprecedented global impacts, COVID-19 may influence how people prioritize issues related to wildlife conservation. Using a nationally representative sample of US residents, we investigated: (1) how COVID-19 affected the relative importance of conservation issues among adults with different political ideologies, and (2) how the pandemic affected political polarization of conservation issues during the 2020 general election in the United States. Conservation issues such as endangered species and controlling zoonotic disease ranked low in importance among the 14 policy issues considered, even lower than environmental issues such as climate change and environmental protection; however, the importance of all conservation issues increased as a result of COVID-19. Political polarization surrounding the perceived importance of conservation issues also increased during the COVID-19 pandemic, with Democrats reporting larger increases in importance than Republicans. Polarization was driven by the most conservative Republicans and the most liberal Democrats. But this polarization was less extreme than it was for other issues such as climate change and healthcare. Findings highlight the need for communicating links between zoonotic disease and human interactions with wildlife and the environment. Acting quickly may be critical in areas where conservation issues are primed to succumb to political polarization.

Self-reported participation in outdoor and nature-based recreation before and during the COVID-19 pandemic supports psychological health and well-being.

Restrictions associated with the COVID-19 pandemic significantly altered daily lives and affected human health and well-being. Outdoor and nature-based activities could potentially mitigate some of these negative impacts. To assess the impact of the COVID-19 pandemic on outdoor recreation and subjective well-being, we combined two samples of U.S. adults collected from April 30th - June 15th, 2020 and from August 7th - August 26th, 2020 (total n = 2178) using Qualtrics XM. During the pandemic, participation in outdoor activities declined by 35%, participation in nature-based activities declined by 33%, and subjective well-being declined by 24%. Participation in outdoor activities and nature activities prior to the pandemic and during the pandemic predicted smaller declines in subjective well-being. Results highlight the importance of outdoor recreation for building resilience to changes in subjective well-being before and during global crises like the COVID-19 pandemic.

Nature as an Ecological Asset for Positive Youth Development: Empirical Evidence From Rural Communities.

Despite increasing emphasis on youth contact with nature and associated benefits, research has not examined the direct relationship between adolescents' nature-based experiences and holistic measures of positive youth development (PYD). This gap may stem from the lack of interdisciplinary work on nature and PYD. Our study integrates multiple disciplinary perspectives to explore direct associations between time in nature, connection to nature, and the five Cs of PYD (competence, connection, confidence, character, and caring) as well as the "sixth" C of contribution. From 2015 to 2016, we collected data from 587 diverse South Carolina middle school students (57% female, 40% BIPOC) between the ages of 11 and 14 (M age = 12.9) and living in predominantly low-income communities. OLS regression analyses indicated that across all youth, self-reported connection to nature was a consistent positive correlate of overall PYD and each of the individual Cs. Time in nature was associated with overall PYD and competence. Findings demonstrate significant associations between nature-based experiences and PYD and underscore the importance of ensuring that diverse youth can access and enjoy the developmental benefits of nature and nature-based recreation opportunities.

Outdoor Activity Participation Improves Adolescents' Mental Health and Well-Being during the COVID-19 Pandemic.

COVID-19 is reshaping human interactions with the natural environment, potentially generating profound consequences for health and well-being. To assess the effects of COVID-19 on the outdoor recreation participation and subjective well-being of adolescents, as well as how participation in outdoor activities may mitigate declines in subjective well-being, we used a Qualtrics XM panel to conduct a nationally representative survey of youth ages 10-18 across the United States (n = 624) between 30 April and 15 June 2020. Survey questions focused on frequency of participation in outdoor activities before and during the pandemic, as well as changes in subjective well-being. Paired t-tests revealed decreases in both outdoor recreation participation (64% reported declines) and subjective well-being (52% reported declines). A regression model examining correlates of changes in subjective well-being (R2 = 0.42) revealed strong associations with changes in outdoor play (B = 0.44, p < 0.001) and nature-based (B = 0.21, p = 0.016) activities. Adolescents' from all backgrounds who participated in these activities during the pandemic reported smaller declines in subjective well-being. Results highlight the critical role that time outdoors and time in nature play in bolstering adolescents' resilience to stressors such as the COVID-19 pandemic and underscore the need to facilitate outdoor recreation opportunities for youth during times of crisis.

Neighborhood Built Environment Impacts Park Use of Diverse, Low-Income Mothers With Their Children.

Built environment features, including parks, often exacerbate health disparities. We examined built environment perceptions and park use among a population at high risk for negative physical health outcomes: racially diverse, low-income mothers across the United States. Perceived safety from crime and living near a park were associated with more frequent park use for mothers with their children, and neighborhood walkability was linked to longer park visits. However, only 40% of mothers lived within a 10-minute walk of a park, and overall perceptions of walkability and safety from crime were low. To enhance physical activity and health of low-income mothers with their children, investments are needed to close disparities in park access and improve neighborhood safety.

Psychological impacts from COVID-19 among university students: Risk factors across seven states in the United States.

BACKGROUND: University students are increasingly recognized as a vulnerable population, suffering from higher levels of anxiety, depression, substance abuse, and disordered eating compared to the general population. Therefore, when the nature of their educational experience radically changes-such as sheltering in place during the COVID-19 pandemic-the burden on the mental health of this vulnerable population is amplified. The objectives of this study are to 1) identify the array of psychological impacts COVID-19 has on students, 2) develop profiles to characterize students' anticipated levels of psychological impact during the pandemic, and 3) evaluate potential sociodemographic, lifestyle-related, and awareness of people infected with COVID-19 risk factors that could make students more likely to experience these impacts. METHODS: Cross-sectional data were collected through web-based questionnaires from seven U.S. universities. Representative and convenience sampling was used to invite students to complete the questionnaires in mid-March to early-May 2020, when most coronavirus-related sheltering in place orders were in effect. We received 2,534 completed responses, of which 61% were from women, 79% from non-Hispanic Whites, and 20% from graduate students. RESULTS: Exploratory factor analysis on close-ended responses resulted in two latent constructs, which we used to identify profiles of students with latent profile analysis, including high (45% of sample), moderate (40%), and low (14%) levels of psychological impact. Bivariate associations showed students who were women, were non-Hispanic Asian, in fair/poor health, of below-average relative family income, or who knew someone infected with COVID-19 experienced higher levels of psychological impact. Students who were non-Hispanic White, above-average social class, spent at least two hours outside, or less than eight hours on electronic screens were likely to experience lower levels of psychological impact. Multivariate modeling (mixed-effects logistic regression) showed that being a woman, having fair/poor general health status, being 18 to 24 years old, spending 8 or more hours on screens daily, and knowing someone infected predicted higher levels of psychological impact when risk factors were considered simultaneously. CONCLUSION: Inadequate efforts to recognize and address college students' mental health challenges, especially during a pandemic, could have long-term consequences on their health and education.
