The COVID-19 pandemic presents not only a global health crisis but has also disrupted the daily lives of people around the world. From a leisure perspective, urban outdoor enthusiasts are one group particularly impacted by the pandemic and the subsequent institutional response. Stay-at-home orders and physical distancing recommendations serve as potential inhibitors to outdoor recreation activities central to the lifestyles and wellbeing of outdoor enthusiasts. In urban areas, where these orders and recommendations are most restrictive, the potential impacts on recreation behavior are most consequential. This study provides an empirical analysis of the COVID-19 pandemic’s impact on the recreational behaviors of outdoor enthusiasts across urban and rural communities. Results suggest that the frequency of outdoor recreation participation, distance travelled to participate in outdoor recreation and distance travelled beyond roads during outdoor recreation have declined significantly more among outdoor enthusiasts residing in urban areas than urban clusters or rural areas.

Background: Human impacts on the environment are so great that we are at risk of changing the state of the planet from one that is hospitable to one that is hostile to humanity.

Understanding variations in habitat use through time contributes to identification of habitats critical for species survival. Here we used passive acoustic telemetry to examine the residency and site fidelity patterns of the reef manta ray Mobula alfredi at Lady Elliot Island (LEI), a key aggregation site in eastern Australia. Six acoustic receivers were moored around LEI between 2009 and 2012, and 34 acoustic transmitters were deployed on manta rays. All tagged animals returned to this site within their recording period, with some individuals visiting the area for up to 23 consecutive days. Using a set of mixed effect models, we analysed the hourly visitation patterns of manta rays in relation to temporal and environmental variables. Diel phase and sea temperature showed the strongest effects on the presence of manta rays, with weaker effects detected for wind direction, wind speed and moon illumination. Individuals occupied LEI habitat mostly during daylight hours and in calm weather conditions, which may be linked with behavioural thermoregulation, social interactions and cleaning activities. Their absence at night may be related to foraging strategies in deeper offshore waters. The effect of sea temperature reflects the greater seasonal occurrence of manta rays at LEI in winter, when temperatures are coolest, potentially in response to regional food availability. The high degree of manta ray site fidelity at aggregation sites underscores the importance of these areas as key daytime habitats for the species. We suggest that conservation measures should prioritise the protection of coastal aggregation habitats from overexploitation and degradation.

Research has found that human-caused noise can detract from the quality of the visitor experience in national parks and related areas. Moreover, impacts to the visitor experience can be managed by formulating indicators and standards of quality as suggested in park and outdoor recreation management frameworks, such as Visitor Experience and Resource Protection (VERP), as developed by the U.S. National Park Service. The research reported in this article supports the formulation of indicators and standards of quality for human-caused noise at Muir Woods National Monument, California. Phase I identified potential indicators of quality for the soundscape of Muir Woods. A visitor "listening exercise" was conducted, where respondents identified natural and human-caused sounds heard in the park and rated the degree to which each sound was "pleasing" or "annoying." Certain visitor-caused sounds such as groups talking were heard by most respondents and were rated as annoying, suggesting that these sounds may be a good indicator of quality. Loud groups were heard by few people but were rated as highly annoying, whereas wind and water were heard by most visitors and were rated as highly pleasing. Phase II measured standards of quality for visitor-caused noise. Visitors were presented with a series of 30-second audio clips representing increasing amounts of visitor-caused sound in the park. Respondents were asked to rate the acceptability of each audio clip on a survey. Findings suggest a threshold at which visitor-caused sound is judged to be unacceptable, and is therefore considered as noise. A parallel program of sound monitoring in the park found that current levels of visitor-caused sound sometimes violate this threshold. Study findings provide an empirical basis to help formulate noise-related indicators and standards of quality in parks and related areas.
