The first volunteer programme to be held in 2023 at Krka National Park is the Krka’s Habitat Protector, as part of the project LIFE CONTRA Ailanthus, in which Krka National Park is a partner. The project is financed through the LIFE programme.

The aim of the volunteer programme “Indigenous species habitat protector” is the removal of Tree of Heaven, an invasive species that threatens the native species in Krka National Park. The programme also raises awareness among the local population with the aim of changing behaviour patterns and attitudes towards nature.

In order to protect habitats and indigenous plant species, and to prevent the spread of the invasive Tree of Heaven, the Public Institute of Krka National Park participates as a partner in the project to establish control over its trees. Krka National Park has selected eight localities for the elimination of Tree of Heaven. As part of the project, four groups of external experts were selected to perform the task of developing alternative protocols to remove the invasive species Tree of Heaven (Ailanthus altissima). As part of field activities, experts will collect and analyse data and assess the effects of the projects on different habitats, pollinators and soil biodiversity, and this year, volunteers will be joining in.

The volunteer programme will take place from 1 to 10 September 2023, for five to seven hours per day. The volunteer activities will be performed at the selected areas of Krka National Park and in the town of Skradin, where large Trees of Heaven were previously removed. Accommodation and food are provided in the Volunteer Centre at the Krka Eco Campus in Puljane.

If you like to spend time outdoors and want to get to know more about the natural values and cultural and historical sights of interest in Krka National Park, learn more about nature protection systems, and preserve the biodiversity of the Park, apply to volunteer at Krka National Park, and become a Krka Habitat Protector.
