Yosemite National Park is a popular tourist destination with high visitation levels that have increased throughout the summer season over the past several decades. Like with other protected areas, high visitation levels pose challenges for coordinating resources, infrastructural capacity, and visitor experiences. Use limits, including rationing vehicle entry at gates by reservation, are one possible strategy to manage visitation levels. After an initial full closure, the park chose to operationalize a multiphased permit system for day-use and overnight entry over the course of the pandemic in accordance with local and national guidelines for operational safety. While park closures and other entry restrictions have been common in recent years due to wildland fires and other natural hazards, the pandemic-related entry limits represent a nearly yearlong experiment. The prolonged entry ration along with restrictions to group activities has limited visitation and potentially reduced transmission of the novel coronavirus. We review the per capita COVID-19 case count in surrounding counties given the flow of tourism from outside the region, assess the changes in access to the park with the novel reservation system, compare monthly visitation during the 2020 use limits with prior decadal averages, detail how high visitation levels and crowding persist, and review the Park’s plans for an ongoing day-use permit system. We conclude with the ongoing challenges managers face in light of continued high visitation. Readers will be able to debate the efficacy of use limits and what may be a sustainable level of visitation for the park.
Local ethnobiological knowledge offers critical insights into ecological processes, species diversity, and abundance, as well as changes in environmental conditions. Although ethnomycological knowledge remains understudied compared to local knowledge about plants and animals, wild fungi are important components of healthy, functioning ecosystems. Wild fungi are also integral to many social and economic systems. Yunnan Province, China, is home to both a wide diversity of wild edible mushrooms and extensive human-fungi relationships. Understanding local ecological and mycological knowledge is critical for conserving ecological systems and promoting sustainable livelihoods. This study investigates indigenous Yi ethnomycological knowledge in four communities in Nanhua County using both interviews and harvesting observations. The comparative merits and limitations of each method are assessed. Around 90 unique, named folk species were reported or observed in the study communities, with 54 species reported multiple times. Local mushroom names encode information about local ecology, species morphology, and abstract metaphorical ideas. In addition, harvesters variably referred to mushrooms in Yi, Mandarin, or with general descriptive categories, suggesting a link between species use, value, and naming conventions. This study found that directly observing mushroom harvests captured more detailed knowledge compared to recall-based interviews, including both a greater number of species and a more nuanced, multi-leveled taxonomic system. However, interviews revealed the cultural salience, economic values, and culinary preferences for many local mushroom species. These results highlight the importance of mixed-methods approaches to ethnoecological knowledge, as both recall and observational data may lead to different conclusions about local species abundance and diversity.
Matsutake mushrooms are an important part of rural livelihoods and forest ecosystems across large parts of China, as well as elsewhere in East Asia, Northern Europe and North America. Mushroom harvesters have developed sophisticated understandings of matsutake ecology and production, and are applying this knowledge in various innovative management strategies. At the same time, Chinese government agencies and scientists are promoting matsutake-based livelihoods to support development and conservation goals. We collaborated with matsutake harvesters in one Yunnan community to carry out a systematic experiment on a popular shiro-level management technique: covering matsutake shiros with either plastic or leaf litter. Our experimental results suggest that although leaf litter coverings are superior to plastic coverings, shiros that are left uncovered may produce the highest yields. Complementing our experimental work is a multi-sited household survey of existing matsutake management practices across Yunnan, which shows that a high proportion of harvesters are already engaged in a broad range of potentially beneficial management strategies. Though both findings highlight limitations of previous initiatives led by government and research actors in China, this existing body of work is an important foundation and opportunity for developing applied mycology in the region. In and beyond China, working with communities to develop site-specific management strategies through rigorous and participatory scientific inquiry can provide salient benefits for both scientists and resource users.
