HaCloRi - Research to identify and prevent pollution of the Jelševniščice and Otovec catchments, with particular reference to the habitat of the black tern

Content
The project focussed on defining measures that would effectively ensure a suitable habitat for the survival and reproduction of the white and black subspecies of the Proteus (Proteus anguinus anguinus or Proteus anguinus Anguillid) in the hinterland of two karst springs in Bela Krajina, Jelševniščica and Otovski breg. In order to define scientifically justified, relevant and targeted measures, it was essential to assess the extent and sources of groundwater pollution, with a focus on nitrate levels. As both the measures and the pollution are also spatially dependent, it was essential to determine the extent and hydrogeological characteristics of the karst hinterland of both springs.
Three partner organisations integrated interdisciplinary ecological, hydrogeological, agronomic and environmental research within the project activities.
Project phases:
- definition of habitat requirements, determination of the extent and hydrogeological characterisation of the catchment area,
- identification of anthropogenic pollution by linking pollution to source groups,
- definition of measures to ensure favourable conditions for the underground habitat of the white and black subspecies of the Proteus.
