We are an environmental consultant specialized in ecological issues. We are your partner of choice when you need to secure the ecological sustainability of your project. We do advanced GIS-modeling, field studies covering a wide range of methods and taxa, and EIA (Environmental Impact Assessment). We work in terrestrial, marine and freshwater ecosystems.

  • Sampling and chemical analyses of water (runoff water, surface water, ground water, process water, drinking water etc)
  • Sampling and chemical analyses of soil and natural and industrial sediments
  • Electrofishing and net fishing for population estimates and assessment of environmental status
