Urbanisation is altering local flora and fauna, but urban greenspaces can provide refugia for a variety of taxa. However, we often lack basic biodiversity information (e.g., species richness) for these urban greenspaces. Citizen science projects are continuously improving our understanding of ecology at broad temporal and spatial scales. But, many conservation-relevant decisions are idiosyncratic and made at small management scales (e.g., local government). Given a general bias of citizen science data towards areas with large human populations, citizen scientists are best placed to contribute to improving our understanding of the biodiversity within cities and urban greenspaces. We introduce the Greenspace Bird Calculator: a web-app aimed at enhancing our collective knowledge of bird diversity in urban greenspaces. Users of the web-app could be land managers seeking to understand the bird diversity in the greenspaces they manage. It is built in a reproducible workflow, allowing anyone to delineate a greenspace and submit it to the web-app administrator, receiving an output comprising the greenspace’s total bird diversity. The Greenspace Bird Calculator web-app provides an automated tool to utilise existing eBird citizen science data to calculate species richness for urban greenspaces globally. Critically, the GBC web-app statistically assesses available data that otherwise would be unlikely to be considered by decision-makers. This web-app is an example of the evolution of citizen science, whereby the data collected has been analysed to allow accessible interpretation and inclusion into urban greenspace management and planning.

An emerging hypothesis in fire ecology is that pyrodiversity increases species diversity. We test whether pyrodiversity—defined as the standard deviation of fire severity—increases avian biodiversity at two spatial scales, and whether and how this relationship may change in the decade following fire. We use a dynamic Bayesian community model applied to a multi-year dataset of bird surveys at 1106 points sampled across 97 fires in montane California. Our results provide strong support for a positive relationship between pyrodiversity and bird diversity. This relationship interacts with time since fire, with pyrodiversity having a greater effect on biodiversity at 10 years post-fire than at 1 year post-fire. Immediately after fires, patches of differing burn severities hold similar bird communities, but over the ensuing decade, bird assemblages within patches of contrasting severities differentiate. When evaluated at the scale of individual fires, fires with a greater heterogeneity of burn severities hold substantially more species. High spatial heterogeneity in severity, sometimes called ‘mixed-severity fire', is a natural part of wildfire regimes in western North America, but may be jeopardized by climate change and a legacy of fire suppression. Forest management that encourages mixed-severity fire may be critical for sustaining biodiversity across fire-prone landscapes.

AbstractInformation on species’ distributions and abundances, and how these change over time are central to the study of the ecology and conservation of animal populations. This information is challenging to obtain at relevant scales across range-wide extents for two main reasons. First, local and regional processes that affect populations vary throughout the year and across species’ ranges, requiring fine-scale, year-round information across broad — sometimes hemispheric — spatial extents. Second, while citizen science projects can collect data at these scales, using these data requires appropriate analysis to address known sources of bias. Here we present an analytical framework to address these challenges and generate year-round, range-wide distributional information using citizen science data. To illustrate this approach, we apply the framework to Wood Thrush (Hylocichla mustelina), a long-distance Neotropical migrant and species of conservation concern, using data from the citizen science project eBird. We estimate occurrence and relative abundance with enough spatiotemporal resolution to support inference across a range of spatial scales throughout the annual cycle. Additionally, we generate intra-annual estimates of the range, intra-annual estimates of the associations between species and the local environment, and inter-annual trends in relative abundance. This is the first example of an analysis to capture intra- and inter-annual distributional dynamics across the entire range of a broadly distributed, highly mobile species.

Understanding species-specific relationships with their environment is essential for ecology, biogeography, and conservation biology. Moreover, understanding how these relationships change with spatial scale is critical to mitigating potential threats to biodiversity. But methods which measure inter-specific variation in responses to environmental parameters, generalizable across multiple spatial scales, are lacking. We used broad-scale citizen science data, over a continental scale, integrated with remotely-sensed products, to produce a measure of response to urbanization for a given species at a continental-scale. We then compared these responses to modelled responses to urbanization at a local-scale, based on systematic sampling within a series of small cities. For 49 species which had sufficient data for modelling, we found a significant relationship (R2 = 0.51) between continental-scale urbanness and local-scale urbanness. Our results suggest that continental-scale responses are representative of small-scale responses to urbanization. We also found that relatively few citizen science observations (~250) are necessary for reliable estimates of continental-scale urban scores to predict local-scale response to urbanization. Our method of producing species-specific urban scores is robust and can be generalized to other taxa and other environmental variables with relative ease.

By 2030, ten percent of earth’s landmass will be occupied by cities. Urban environments can be home to many plants and animals, but surveying and estimating biodiversity in these spaces is complicated by a heterogeneous built environment where access and landscaping are highly variable due to human activity. Citizen science approaches may be the best way to assess urban biodiversity, but little is known about their relative effectiveness and efficiency. Here, we compare three techniques for acquiring data on butterfly (Lepidoptera: Rhopalocera) species richness: trained volunteer Pollard walks, Malaise trapping with expert identification, and crowd-sourced iNaturalist observations. A total of 30 butterfly species were observed; 27 (90%) were recorded by Pollard walk observers, 18 (60%) were found in Malaise traps, and 22 (73%) were reported by iNaturalist observers. Pollard walks reported the highest butterfly species richness, followed by iNaturalist and then Malaise traps during the four-month time period. Pollard walks also had significantly higher species diversity than Malaise traps.

The India Biodiversity Portal (IBP) was initiated a decade ago, aiming to aggregate data on all species within India. The portal has been running a citizen science module for the past 8 years, aggregating observation data from the general public. The portal runs many flagship citizen science campaigns, such as the Neighborhood Trees Campaign, National Moth Week, Spotting Alien Invasive species, Mapping Indian Snails and Slugs and Frogwatch. We have learnt valuable lessons in harnessing participation in citizen science, implementing functionality and in integrating technological advancements into the platform codebase. Following up on these, we are implementing new features that will streamline development, entice users and further spur participation. We discuss some of the proposed changes and our justification, including the impacts we expect in generating better citizen science data. A key lesson arising out of our campaigns in remote regions of India, where internet penetration is relatively new, is that most users are connected to the web exclusively through a mobile device. Most do not have access to a personal computer or an email account. Yet they are internet savvy and use mobile applications to accomplish complex tasks such as banking activities, often logging in and being authenticated exclusively through a mobile number. We are implementing short-messaging-service (SMS) or one-time password-based login mechanisms, for login even without an email account for authentication. Although many initiatives have been investing in platform-specific mobile apps to cater to a growing mobile user community, maintaining and updating multiple mobile apps alongside enhancements to the web version is a resource-intensive task that most platforms cannot afford. Inconsistency in functions and usability across different versions of the same platform may lead to gaps in data collection. To address this challenge and streamline development, we have begun updating the portal codebase to enable Progressive Web Apps, which will replace conventional mobile applications while also serving as Single Page Applications that provide a unified experience across device platforms and alleviating the need for updating mobile apps separately. For existing contributors on the portal, comparisons of their contributions against other users are a motivating factor to contribute further. Leaderboards and reputation systems are proven methods to promote activity and provide recognition to participants. Such leaderboards also incentivise newer participants to emulate leaders and climb the boards. We are building a reputation system that not only recognizes quantity but also the quality of the user’s contribution. In addition, we are working on integrating intelligent push notification technology that will constantly engage users by keeping them abreast of activity related to content reflecting their interest on the portal. These features are expected to engage contributors and keep them motivated towards further data contributions. Finally, the most rewarding outcome from contributing citizen science data is in visualizing its impact. The most obvious are improvements in species distribution maps that are generated for each species page on the portal. Users are greatly motivated by contributing data that may enhance known distributions and may constitute range extensions for a species. Distribution maps on the portal are being revamped so that information is presented to the user in real-time through visualisations that are are both attractive and easy to interpret. These will provide users with gratification and help spur participation further. IBP is also instituting the ability to automate the classification of its data to identify publication-grade data. Through a combination of user’s reputation and other data quality criteria, the data on IBP will be automatically graded, allowing such data to be pushed to Global Biodiversity Information Facility on a periodic basis as a Darwin Core Archive, contributing to global biodiversity data.
