Unlike populations of the Marsh Fritillary in moist habitats, there is still limited knowledge about habitat preferences in dry habitats. Our research project therefore includes extensive studies at both the habitat and landscape levels. We investigate not only the colonization dynamics of the butterfly but also the impact of ongoing habitat fragmentation on the species’ current distribution using Functional Connectivity and Extinction Debt.

To calculate Functional Connectivity, we analyze the different spatial resistances of the landscape matrix. For assessing Extinction Debt, we use historical satellite images to determine the size of the calcareous grasslands. To ensure future conservation measures for the Marsh Fritillary and its habitat are more targeted, we conduct ecological monitoring of the restoration activities.

In addition, the project includes public outreach efforts aimed at increasing appreciation of biodiversity among tourists in the region. The success of these outreach efforts is evaluated through a socio-economic assessment.
