Third Paper published

We published our third paper in the project in the Journal BMC Ecology yesterday (27 June 2017). The article is open access available, please visit the article webpage to read the fulltext: https://link.springer.com/article/10.1186%2Fs12898-017-0134-z

We would also be happy if you read and share our blog: http://blogs.biomedcentral.com/bmcseriesblog/2017/07/07/using-citizen-science-to-monitor-road-kills/

To get an impression, here is our abstract:

Background

Amphibians and reptiles are among the most endangered vertebrate species worldwide. However, little is known how they are affected by road-kills on tertiary roads and whether the surrounding landscape structure can explain road-kill patterns. The aim of our study was to examine the applicability of open-access remote sensing data for a large-scale citizen science approach to describe spatial patterns of road-killed amphibians and reptiles on tertiary roads. Using a citizen science app we monitored road-kills of amphibians and reptiles along 97.5 km of tertiary roads covering agricultural, municipal and interurban roads as well as cycling paths in eastern Austria over two seasons. Surrounding landscape was assessed using open access land cover classes for the region (Coordination of Information on the Environment, CORINE). Hotspot analysis was performed using kernel density estimation (KDE+). Relations between land cover classes and amphibian and reptile road-kills were analysed with conditional probabilities and general linear models (GLM). We also estimated the potential cost-efficiency of a large scale citizen science monitoring project.

Results

We recorded 180 amphibian and 72 reptile road-kills comprising eight species mainly occurring on agricultural roads. KDE+ analyses revealed a significant clustering of road-killed amphibians and reptiles, which is an important information for authorities aiming to mitigate road-kills. Overall, hotspots of amphibian and reptile road-kills were next to the land cover classes arable land, suburban areas and vineyards. Conditional probabilities and GLMs identified road-kills especially next to preferred habitats of green toad, common toad and grass snake, the most often found road-killed species. A citizen science approach appeared to be more cost-efficient than monitoring by professional researchers only when more than 400 km of road are monitored.

Conclusions

Our findings showed that freely available remote sensing data in combination with a citizen science approach would be a cost-efficient method aiming to identify and monitor road-kill hotspots of amphibians and reptiles on a larger scale.

Macro-Ecology Conference Vienna

The 10th Annual Meeting of the Macroecology Working Group for the Ecological Society Germany, Austria & Switzerland was held from 19-21 April 2017. This year, the titel of the conference was "Macroecology in Space and Time". Colleagues from the University of Vienna organised the conference with a broad focus on conservation biology, evolution and global change. We took the opportunity of living at the conference venue and presented a poster on our project and some new results.

New citizen science paper published

Today (10th October 2016) we published a new paper in Remote Sensing with the title "Comparing Road-Kill Datasets from Hunters and Citizen Scientists in a Landscape Context".

It is open access and therefore free for everyone to read: http://www.mdpi.com/2072-4292/8/10/832/htm

We really wish to thank all citizen scientists in Project Roadkill for investing time and reporting data.

Road traffic has severe effects on animals, especially when road-kills are involved. In many countries, official road-kill data are provided by hunters or police; there are also road-kill observations reported by citizen scientists. The aim of the current study was to test whether road-kill reports by hunters stem from similar landscapes than those reported by citizen scientists. We analysed the surrounding landscapes of 712 road-kill reportings of European hares in the province of Lower Austria. Our data showed that road-killed hares reported both by hunters and citizens are predominantly surrounded by arable land. No difference of hedges and solitary trees could be found between the two datasets. However, significant differences in landcover classes and surrounding road networks indicate that hunters’ and citizen scientists’ data are different. Hunters reported hares from landscapes with significantly higher percentages of arable land, and greater lengths of secondary roads. In contrast, citizens reported hares from landscapes with significantly higher percentages of urban or industrial areas and greater lengths of motorways, primary roads, and residential roads. From this we argue that hunters tend to report data mainly from their hunting areas, whereas citizens report data during their daily routine on the way to/from work. We conclude that a citizen science approach is an important source for road-kill data when used in addition to official data with the aim of obtaining an overview of road-kill events on a landscape scale.

Dialogue at eye level

Knowledge of citizens and its potential integration in professional institutions

In recent years citizen science is getting more important in professional science. More and more professional scientists are integrating citizens in their research. However what is citizen science and where does it come from? Which impact does citizen science have on the cooperation of laypersons and professionals? How do citizen science projects work and are there examples in Austria? Can we do something to promote citizen science in Austria and make it easier for laypersons?

Florian Heigl and Daniel Dörler are answering these questions in German in the "Jahrbuch 2015 der Bildung für eine nachhaltige Entwicklung", which was published in June 2015.

Using a Citizen Science Approach in Higher Education: A Case Study Reporting Roadkills in Austria

We published our manuscript "Using a Citizen Science Approach in Higher Education: A Case Study Reporting Roadkills in Austria" von Florian Heigl und Johann Zaller; Fachzeitschrift Human Computation - Volume 1, Issue 2 (Citizen Science Special Issue); December 2014

Abstract:

Using a Citizen Science Approach in Higher Education: A Case Study Reporting Roadkills in Austria

FLORIAN HEIGL, Universität für Bodenkultur, Wien

Citizen cyber-science as a crowdsourcing method is gaining popularity around the world especially in projects dealing with environmental issues. Many European universities are faced with increasing student numbers along with unchanged numbers of advising lecturers and professors. Thus, a challenge for natural science educators is to teach and transfer knowledge despite weak lecturer-to-student ratios. In search for a solution to this problem, we applied a citizen science crowdsourcing approach in an obligatory course of the Bachelor programme of Environment and Bio-Resources Management at the University of Natural Resources and Life Sciences Vienna, Austria. The project, called BOKUroadkill, engaged students in reporting roadkilled animals they observed during their daily routine over a period of three months. Data collection was carried out via a freely available, customized mobile app (EpiCollect) that ran on students’ private devices or via an additional online reporting form for students without smartphones or tablets. After three months, 109 students reported 1,236 animals killed on roads, analysed roadkill patterns, and provided feedback on the project. Based on this feedback, we developed a new online platform extending the project for all citizens to participate (www.citizen- science.at/roadkill). Based on our experience with BOKUroadkill, we conclude that a citizen science approach in higher education is suitable for (1) courses with weak lecturer-to-student ratios, (2) addressing important elements of motivation for learners and (3) familiarizing students with scientific research. Our results indicate that citizen cyber-science projects can well be developed as student projects initially before extending the project to a broader public.
