Resumo
Citizen science data (CSD) have the potential to be a powerful scientific approach to assess, monitor
and predict biodiversity. Here, we ask whether CSD could be used to predict biodiversity of recently
constructed man-made habitats. Biodiversity data on adult dragonfly abundance from all kinds of
aquatic habitats collected by citizen scientists (volunteers) were retrieved from the Swedish Species
Observation System and were compared with dragonfly abundance in man-made stormwater
ponds. The abundance data of dragonflies in the stormwater ponds were collected with a scientific,
standardized design. Our results showed that the citizen science datasets differed significantly from
datasets collected scientifically in stormwater ponds. Hence, we could not predict biodiversity in
stormwater ponds from the data collected by citizen scientists. Using CSD from past versus recent years
or from small versus large areas surrounding the stormwater ponds did not change the outcome of
our tests. However, we found that biodiversity patterns obtained with CSD were similar to those from
stormwater ponds when we restricted our analyses to rare species. We also found a higher beta diversity
for the CSD compared to the stormwater dataset. Our results suggest that if CSD are to be used for
estimating or predicting biodiversity, we need to develop methods that take into account or correct for
the under-reporting of common species in CSD.
