Protecting Turtle Eggs & Nests

Conserving Slovakia's European Pond Turtle

Each two months, our members are given the chance to vote for a rewilding project they want to see us carry out at one of our projects. Together with our partners, we select three options for high-impact conservation projects that support the rewilding vision for the area. For the Spring 2020 rewilding project, we head to the location of our new project, Slovakia, where we work with our amazing partners, Broz, to restore the Danube floodplain forests. Our members were given the choice between meadow restoration, habitat restoration for the Pannonian root vole and protecting European pond turtle eggs & nests. Our members chose to support the wonderful work to protect Slovakia's endangered population of European pond turtles.

On The Brink

Fossil records show the European pond turtle (Emys orbicularis) has been present in Slovakia for at least 120,000 years. However, in recent years it has disappeared from much of its range. Today, there are only two known sites with a viable breeding population in Slovakia. These pond turtles live in open habitats and rely on wetlands, ponds and water channels for hunting and moving. Eggs are laid in shallow under ground nests in sandy soils with little vegetation. Depending on the weather, the hatchlings can remain at the nest site throughout winter and start emerging in spring following year. Unfortunately, the European pond turtle is losing suitable breeding habitat across much of its range as land is converted to agriculture and nests destroyed and turtles killed by agricultural disturbance.

Promoting Breeding

The nesting behaviour of these pond turtles leaves them susceptible to predators as well. Our partners have access to one of the last remaining breeding populations in Slovakia, where predation is the main threat. Predator protection measures are there a vital conservation intervention to protect this important population. The project funds the training of detection dog to detect turtle eggs underground. Since nests are practically invisible to the human eye, the detection dog will accompany the field team to the breeding site to survey for active nests. Fences are erected over active nests to protect the eggs and hatchlings from predators, thereby helping to improve the reproductive success of one of Slovakia’s last remaining breeding populations of European pond turtle.

GPS Tracking

To support the conservation of the turtles more widely, the team are tagging turtles with GPS trackers to enable them to monitoring their movement patterns in the long term. This will provide crucial data to enable the team to identify important areas of habitat for protection and restoration, including any unknown breeding sites.
