Opportunistic citizen science (CS) programs allow volunteers to report species observations from anywhere, at any time, and can assemble large volumes of historic and current data at faster rates than more coordinated programs with standardized data collection. This can quickly provide large amounts of species distributional data, but whether this focus on participation comes at a cost in data quality is not clear. Although automated and expert vetting can increase data reliability, there is no…

Citizen Science Data Collection for Integrated Wildlife Population Analyses

Citizen science, or community science, has emerged as a cost-efficient method to collect data for wildlife monitoring. To inform research and conservation, citizen science sampling designs should

Species density models from opportunistic citizen science data

With the advent of technology for data gathering and storage, opportunistic citizen science data are proliferating. Species distribution models (SDMs) aim to use species occurrence or abundance for

Opinions of citizen scientists on open access to UK butterfly and moth occurrence data

Citizen science plays an increasingly important role in biodiversity research and conservation, enabling large volumes of data to be gathered across extensive spatial scales in a cost-effective

Optimizing future biodiversity sampling by citizen scientists

A novel framework which assigns every citizen science sampling event a marginal value, derived from the importance of an observation to the understanding of overall population trends is developed, and it is found that past observations are useful in forecasting where high-value observations will occur in the future.

Who and Where Are the Observers behind Biodiversity Citizen Science Data? Effect of Landscape Naturalness on the Spatial Distribution of French Birdwatching Records

The study of spatial bias in opportunistic data produced by citizen science programs is mainly approached either from a geographical angle (site proximity, accessibility, habitat quality) or from the

Caterpillar Patterns in Space and Time: Insights From and Contrasts Between Two Citizen Science Datasets

Caterpillars are an important component of forest ecosystems as both herbivores on woody and herbaceous vegetation and as a food resource for higher trophic levels. Trends in the abundance, biomass,

Improving big citizen science data: Moving beyond haphazard sampling

This paper argues that the haphazard structure of the data has been seen as an unfortunate but unchangeable aspect of citizen science data, and provides a very simple, tractable framework that could be adapted by broadscale citizen science projects to allow citizen scientists to optimize the marginal value of their efforts.

50 Years of Cumulative Open-Source Data Confirm Stable and Robust Biodiversity Distribution Patterns for Macrofungi

Fungi are a hyper-diverse kingdom that contributes significantly to the regulation of the global carbon and nutrient cycle. However, our understanding of the distribution of fungal diversity is often

Using citizen science data to inform the relative sensitivity of waterbirds to natural versus human‐dominated landscapes in China

The potential for citizen science data to assist in conservation planning in the context of landscape changes is demonstrated and the relative sensitivity of waterbird species to natural versus human‐dominated landscapes is reported.



Citizen science contributes to our knowledge of invasive plant species distributions

The extent to which citizen science data can increase sampling coverage, fill gaps in species distributions, and improve habitat suitability models compared to professionally generated data sets used in isolation is demonstrated.

Using citizen science butterfly counts to predict species population trends

It is found that mass-participation citizen science can simultaneously contribute to public engagement and biodiversity monitoring, as well as serving to reconnect an increasingly urban human population with nature.

Safari Science: assessing the reliability of citizen science data for wildlife surveys

Summary Protected areas are the cornerstone of global conservation, yet financial support for basic monitoring infrastructure is lacking in 60% of them. Citizen science holds potential to address

Improving and integrating data on invasive species collected by citizen scientists

A unified yet flexible national citizen science program aimed at tracking invasive species location, abundance, and control efforts could be designed using centralized data sharing and management tools, and a prototype for such a system is presented.

Expert variability provides perspective on the strengths and weaknesses of citizen-driven intertidal monitoring program.

The accuracy of data collected by secondary school students as citizens in a program that quantitatively sampled benthic rocky intertidal communities at 13 sites on Maui, Molokai, Oahu, and Hawai'i island during the years 2004-2007 was evaluated.

Improving Biodiversity Knowledge with Data Set Synergy: A Case Study of Nonnative Plants in Colorado1

Overall, inclusion of more data types greatly increased knowledge of the nonnative species in Colorado, and harnessing the synergy of disparate data sets seems to be a cost-effective first step to increase knowledge of species richness in an area.

Citizen Science as an Ecological Research Tool: Challenges and Benefits

Citizen science, the involvement of volunteers in research, has increased the scale of ecological field studies with continent-wide, centralized monitoring efforts and, more rarely, tapping of
