PROFILE

Who doesn’t love hedgehogs? Well, at least I absolutely adore European hedgehogs! Therefore, I have decided that my goal in life is to improve the conservation of this fascinating and popular species through my research and the collaboration with, and communication of my research, to the public and the dedicated people working with hedgehog rehabilitation.

Unfortunately, scientific research from several European countries indicate that the population of European hedgehogs is in decline all over Europe. It is therefore essential to investigate the causes for the decline and enhance the understanding of the challenges hedgehogs face in the wild in order to improve the conservation initiatives directed at this species.

I am very grateful to be affiliated with WildCRU, and I am certain my work will benefit from the long tradition and expertise in hedgehog research and conservation which WildCRU has gained over the years.

I have worked with scientific research on hedgehogs since 2011, where I volunteered at a wildlife rehabilitation centre in Denmark and decided the focus of my Master’s thesis in Wildlife Ecology and Conservation should be on hedgehog ecology. I have worked wholeheartedly on my research on hedgehogs ever since, and have even earned the nickname “Dr Hedgehog”.

My PhD project, “The Danish Hedgehog Project” (2016-2019), which I carried out at University of Southern Denmark and Naturama, was based on citizen science. I used the media to encourage volunteering citizens to collect dead hedgehogs for my research. There was an enormous support for the project, and with the participation of over 400 volunteers I received 697 dead hedgehogs from all over Denmark! The 697 hedgehogs have now been necropsied and the samples from these hedgehogs have allowed me to investigate their general health, with research into their genetics and inbreeding, parasitology, age distribution, MRSA prevalence, pesticide accumulation and dental health. The current and planned future research based on these samples (as well as samples collected from hedgehogs in England, Scotland and the Uists) include studies of infectious diseases, endoparasites, the general composition of their microbiomes (the collection of microorganisms including bacteria, archaea, and fungi living in and on the bodies of the hedgehogs) and their food choice. I have also recently investigated the effects and dangers of robotic lawn mowers on hedgehogs.

Hopefully my research will provide an important and detailed insight into the general health and survival challenges of the hedgehogs, enabling us to improve the conservation of this fascinating species so that future generations will also be able to enjoy the unique nature experience of encountering a hedgehog in their garden.

Previous research has established that some models of robotic lawn mowers are potentially harmful to hedgehogs. As the market for robotic lawn mowers is expanding rapidly and the populations of European hedgehogs (Erinaceus europaeus) are in decline, it is important to investigate this risk further to understand the potential threat which some robotic lawn mowers may pose to hedgehogs. We tested 19 models of robotic lawn mowers in collision with hedgehog cadavers to measure their effect on hedgehogs. Our results showed that some models of robotic lawn mowers may injure hedgehogs, whereas others are not harmful to them. Apart from one single incidence, all robotic lawn mowers had to physically touch the hedgehog carcasses to detect them. Larger hedgehog cadavers were less likely to be “injured”, with height being the most influential measure of size. The firmness of the tested hedgehog cadavers (frozen or thawed) did not influence the outcome of the collision tests. Neither the position of the hedgehog cadavers nor the selected technical features of the lawn mowers affected the probability of injury. Based on the results, we designed a standardised safety test to measure the effect of a specific model of robotic lawn mower on hedgehogs.
