Conservation of carbon resources and values on public lands: A case study from the National Wildlife Refuge System

Public lands in the United States are those land areas managed by federal, state, and county governments for public purposes such as preservation and recreation. Protecting carbon resources and increasing carbon sequestration capacity are compatible with public land management objectives for healthy and resilient habitats, i.e., managing habitats for the benefit of wildlife and ecosystem services can simultaneously capture and store carbon. To evaluate the effect of public land management on carbon storage and review carbon management as part of the land management objectives, we used existing data of carbon stock and net ecosystem carbon balance in a study of the National Wildlife Refuge System (NWRS), a public land management program of the U.S. Fish and Wildlife Service (Service). Total carbon storage of the 364 refuges studied was 16.6 PgC, with a mean value 42,981 gCm-2. We used mixed modeling with Bonferroni adjustment techniques to analyze the effect of time since refuge designation on carbon storage. In general, older refuges store more carbon per unit area than younger refuges. In addition to the age factor, carbon resources are variable by regions and habitat types protected in the refuges. Mean carbon stock and the rate of sequestration are higher within refuges than outside refuges, but the statistical comparison of 364 refuges analyzed in this study was not significant. We also used the social cost of carbon to analyze the annual benefits of sequestrating carbon in these publicly managed lands in the United States, which is over $976 million per year in avoided CO2 emissions via specific conservation management actions. We examine case studies of management, particularly with respect to Service cooperation activities with The Conservation Fund (TCF) Go Zero® Program, Trust for Public Land (TPL) and individuals. Additional opportunities exist in improving techniques to maximize carbon resources in refuges, while continuing to meet the core purpose and need of the NWRS.

A Review of Trends and Knowledge Gaps in Latinx Outdoor Recreation on Federal and State Public Lands

The Latinx population in the United States, estimated to compose 28% of the country’s population by 2050, has a long history of public land use. Yet while research on Latinx outdoor recreation in urban green spaces has increased over the past 20 years, research on Latinx outdoor recreation on federal and state public lands has waned. This study synthesizes the literature on public land use and outdoor recreation on federal and state public lands by the Latinx population in the United States to assess the state of knowledge and to strategically identify research needs in Latinx public land use and outdoor recreation. Our analysis reveals that while institutional barriers such as policies, practices, and procedures that favor some ethnic groups over others continue to exist, barriers to access, such as distance to sites, available free time, and knowledge about how to use public lands may be shifting, offering clues that may help guide informed approaches to outdoor recreation management.

Summer crowds: An analysis of USFS campground reservations during the COVID-19 pandemic

During the COVID-19 pandemic, US public land managers faced the challenge of catering to large increases in camping demand, while maintaining social distancing guidelines. In this paper, we use multivariate linear regression to analyze weekly changes in reservations to US Forest Service (USFS) campgrounds between 2019 and 2020. The regression models estimate the impact of local COVID infection rates, public health restrictions, and spatial spillovers from proximity to National Parks (NPs), metropolitan areas and wildfire on camping demand. Our sample includes 1,688 individual USFS campgrounds from across the contiguous US. The results illustrate the dramatic increases in camping on USFS land that occurred in the summer of 2020 and demonstrate that increases in local infection rates led to significant increases in camping nights reserved in the summer. The results also illustrate that the increase in camping nights reserved at USFS campgrounds was particularly dramatic for campgrounds located near large metropolitan areas and near NPs that saw increases in overall recreational visits. These results point to the important role that public lands played during the pandemic and can help guide public land resource allocations for campground maintenance and operation.

Using Sustainability-Oriented Developer Obligations and Public Land Development to Create Public Value

Swedish municipalities use negotiable developer obligations and public land development in sustainability-profiled districts to achieve various public sustainability objectives. They initiate and govern these districts, which act as models for sustainable urban development and testbeds for new sustainability-related policies, using municipally owned land. Public land development in Sweden enables municipalities to include sustainability-oriented negotiable developer obligations in development agreements. The aim of the study is to investigate how Swedish municipalities use sustainability-oriented negotiable developer obligations together with public land development, and to identify what public value outcomes they currently seek to create by using these public value capture instruments. Sustainability-oriented negotiable developer obligations are investigated in relation to municipalities’ desired public value outcomes in five sustainability-profiled district developments in different Swedish municipalities. Findings illustrate that Swedish municipalities use negotiable developer obligations to create ecological, social and cultural, political, and economic public value outcomes. This calls for more research investigating different forms of value and value creation in relation to public value capture instruments.
