This research examines how the operating expenditures of America's state park systems will be affected by a continued growth in attendance consistent with observed trends as well as potential climate futures. We construct a longitudinal panel dataset (1984–2017) describing the operations and characteristics of all 50 state park systems. These data are analyzed with a time-varying stochastic frontier model. Estimates from the model are used to forecast operating expenditures to midcentury under four different scenarios. The first scenario assumes annual attendance within each state park system will continue to grow (or decline) at the same average annual rate that it has over the period of observation. The subsequent scenarios assume statewide annual mean temperatures will increase following the RCP2.6, RCP4.5, and RCP8.5 greenhouse gas emissions trajectories. Operating expenditures under a scenario where annual growth in attendance stays consistent with observed trends are forecasted to increase 756% by midcentury; this is an order of magnitude larger than projected expenditures under any of the climate scenarios. The future climate change scenarios yielded increases in operating expenditures between 25% (RCP2.6) and 61% (RCP8.5) by 2050. Attendance is the single largest factor affecting the operations of America's state park systems, dwarfing the influence of climate change, which is significant and nontrivial. The future of America's state park systems will depend upon increased support from state legislatures, as well as management actions that generate funds for the maintenance of existing infrastructure and facilities, and the provisioning of services.

Abstract
Ideological value sets have the potential to shape individuals' preferences as well as their psychological and behavioral responses to new information. Being socially constructed, ideologies are likely to be formed and modified through the exchanges individuals have in their established information and communication networks. This study examined whether or not individuals' political ideologies and their access to climate-related information are related to several key factors influencing their perceived capacity to adapt to climate-driven changes to local forest conditions. The key factors investigated include: perceived risk; the willingness to learn about potential impacts; the willingness to plan for variable climate futures; and a general perception of self-efficacy. Data come from a mail survey completed by 420 full-time residents living in three amenity-rich forest-related communities in western North Carolina (United States). The results suggest individuals' political ideologies are related to some, but not all, of the information sources asked about. The results also suggest political ideologies are related to perceived risk, with conservatives perceiving climate-driven changes to local forest conditions as more severe relative to liberals. These findings have several implications regarding the effective dissemination of information related to how increasingly variable climate conditions may affect local forest conditions.

AbstractThis research analyzes individuals' perceived resilience to changing climatic conditions. Specifically, we suggest individual resilience is composed of an awareness of localized risks created because of climate change, a willingness to learn about, and plan for, the potential impacts of altered environmental conditions, and general appraisals of personal adaptive capacities. We hypothesize that resilience is influenced by the characteristics of individuals' social networks and also by their social‐psychological dependence on local environments. Using data collected in three resource‐associated communities within the southeastern United States, our analysis suggests bonding ties may limit individuals' willingness to seek new information about the potential impacts of climate change. Conversely, the data suggest the use of a diverse array of bridging ties is positively associated with information‐seeking behavior. The data also support our hypothesis that individuals' social psychological dependencies on the local environment influences their perceived resilience to changing climatic conditions. By gaining a clearer understanding of how individuals' social networks and social‐psychological dependencies affect their perceived ability to adapt to changing environmental conditions, decision makers can focus on policy solutions that increase adaptive capacities and build social resilience.

Individuals, communities, and societies ascribe a diverse array of values to landscapes. These values are shaped by the aesthetic, cultural, and recreational benefits and services provided by those landscapes. However, across the globe, processes such as urbanization, agricultural intensification, and abandonment are threatening landscape integrity, altering the personally meaningful connections people have toward specific places. Existing methods used to study landscape values, such as social surveys, are poorly suited to capture dynamic landscape-scale processes across large geographic extents. Social media data, by comparison, can be used to indirectly measure and identify valuable features of landscapes at a regional, continental, and perhaps even worldwide scale. We evaluate the usefulness of different social media platforms—Panoramio, Flickr, and Instagram—and quantify landscape values at a continental scale. We find Panoramio, Flickr, and Instagram data can be used to quantify landscape values, with features of Instagram being especially suitable due to its relatively large population of users and its functional ability of allowing users to attach personally meaningful comments and hashtags to their uploaded images. Although Panoramio, Flickr, and Instagram have different user profiles, our analysis revealed similar patterns of landscape values across Europe across the three platforms. We also found variables describing accessibility, population density, income, mountainous terrain, or proximity to water explained a significant portion of observed variation across data from the different platforms. Social media data can be used to extend our understanding of how and where individuals ascribe value to landscapes across diverse social, political, and ecological boundaries.

Context Given the decline in amphibian populations worldwide, it is essential to build a better understanding of human behaviours that jeopardise their survival. Much of the literature regarding the social–psychological determinants of behaviours related to wildlife has focussed solely on general wildlife beliefs rather than specific attitudes towards a particular species. Aims The goal of this study was to assess how individuals' behavioural intentions towards a rare and little-known species, the hellbender salamander (Cryptobranchus alleganiensis), are influenced by their attitudes towards the animal and their more general beliefs about wildlife. Methods Questionnaires were distributed to landowners in Missouri (n = 1 065) and Indiana (n = 1 378) in counties where the hellbender is known to exist. A multinomial logit regression model was used to assess the relationship between basic wildlife beliefs, species-specific attitudes and behavioural intentions towards the hellbender. Key results The response rate was 36.6% in Missouri and 41.0% in Indiana. The more value individuals placed on non-hunting wildlife experiences, the less likely they were to say they would engage in a behaviour harmful to the animal (β = –0.47, P = 0.030). The more negative the attitudes towards the hellbender held by individuals, the less likely they were to say they would remove the hook (β = –0.55, P < 0.001), put the animal back (β = –0.77, P < 0.001), or call a resource professional (β = –0.33, P = 0.023). A comparison of the Akaike information criterion (AIC) scores and model log-likelihood values without (AIC = 2 858.36; LLV = –1 395.18) and with (AIC = 2 232.60; LLV = –1 077.30) the species-specific attitude measure showed that its inclusion improved the model. Conclusions Positive attitudes towards the hellbender and mutualistic wildlife beliefs were related to non-detrimental behavioural intentions. However, attitudes towards the animal were found to be a stronger and more consistent predictor of behavioural intentions than basic wildlife beliefs. Implications Efforts to conserve rare or little-known species should focus outreach strategies on developing positive attitudes towards these species, so as to achieve desired changes in behaviour.
