Our mission

Climate change has highlighted the vulnerability of our ecosystems and societies dependence of ecosystem function and services. Ecosystem functionality is in fact limiting how we can use and develop society. Our ecosystems are presently under strong pressure from land use, urban development and climate change. We take on the challenge of finding the ecologically sustainable solutions in any human action. 


What we do

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.

Our main customers are infrastructure and urban planners, wind power developers, and national and regional authorities working with biodiversity management and the monitoring of human impact on natural resources.


Monitoring and analysis

We carry out environmental monitoring in a variety of natural environments, and of many different organism groups; from bats and butterflies to benthic fauna and macroalgae. We are well acquainted with the national environmental monitoring methodology and standards for environmental data collection. 

Our current long-term commissions for environmental data collection include:

  • 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
  • Sampling and taxonomic analyses of plankton, benthic fauna and macrophytes for assessment of environmental status

Calluna has developed the method ”Biological Infrastructure” for biodiversity assessment and management in large scale exploitation projects such as motorways and railways. The method emphasizes the importance of connetivity between ecosystems, and includes the identification of valuable pathways for organisms, identification of landscapes with high concentrations of valuable pathways, and finding solutions to minimize fragmentation.
