Exploring the influence of activity participation on the economic value of nature-based recreation in the Sierra Nevada.

A more comprehensive understanding of how recreational values and forest visitation rates vary across different activities enables forest managers to tailor conservation and management strategies to align with preferences among visitors, ensuring more effective allocation of budgetary resources. However, current research often focuses on only a few recreational activities, resulting in limited insights for forest managers. This study aims to expand the nature-based activities considered so that management can better serve the broader public. We conduct a travel cost analysis using a large survey-based dataset to estimate the value of nature-based recreation in national forests in the Sierra Nevada region and assess how these values differ across main activities. We categorize recreational activities into five broad groups (Passive, Active, Camping, Winter, and Other) to offer a comprehensive view of recreational preferences. A truncated negative binomial regression accounting for endogenous stratification is used to analyze the relationship between the number of trips to the forests, travel cost, activity categories, and socio-demographic variables. Our results suggest a mean consumer surplus (CS) of $65 per visit per person to national forests in the Sierra Nevada. Aggregated over annual per person visits, the total CS is approximately $313.3 million per year. Our findings reveal variations in CS across activity groups, with winter activities (e.g., skiing, snowboarding) and active activities (e.g., hiking, fishing) attracting the highest number of visits, and the highest total CS. Our results provide valuable insights for national forest managers, facilitating the strategic allocation of limited resources to recreational activities that maximize societal welfare.
