Department of Environmental Engineering
Head of Department: Željko Koren, M.Sc. Civ. Eng., CE, PMP
Department of Environmental Engineering is a leader in the field of environmental engineering and a major provider of environmental impact assessments (EIA) and strategic impact assessments (SEA), together with the accompanying mitigation measures and monitoring programs.
The specialties of one of our portfolio segments, environment protection, for example, are large infrastructural developments for which we have participated in a number of different services in the last 19 years:
- Environment Impact Assessments (EIA) for over 1,000 km of freeways and their variants – approximately 80% of newly built freeways in Croatia and BIH;
- Hundreds of km of highways – approximately 30% of newly built freeways;
- Hundreds of km of railways – approximately 80% of newly built or planned railways;
- Almost 1,000 km of high pressure gas pipelines;
- Numerous other mayor infrastructure projects, such as transmission lines and wind farms
- More than 20 Strategic Environmental Assessments (SEA)
- Over 520 environmental protection projects in total
This demonstrates that we have unparalleled experience in developing EIA’s (more than 300) for such developments in Croatia and the region.
Department of Nature Protection and Landscape Architecture
Head of Department: Ana Ostojić, PhD
Over the years Oikon Ltd. has also emerged as major provider of consultancy services and technical assistance projects related to nature protection. We have developed more than:
- 90 specialist studies,
- 70 nature impact studies,
- 60 environmental monitoring projects,
- numerous long term and scientific projects,
- several management plans.
Oikon has gathered a significant amount of experience in collecting new inventory data for fauna and habitats (birds, large and small mammals, amphibians and reptiles, marine benthic species, fungi, terrestrial habitats etc.) using fieldwork research techniques (photo-traps, ultrasound detectors, radar ornithology, GPS collars/chips for marking and tracking of animals, different biological surveys and sampling depending on the target taxonomic group) and remote sensing techniques (satellite/aerial, sensors and loggers), most of it analysed and presented through specialised spatial analysis tools and methods. We are particularly proud to have been the lead partner and coordinator of the Croatia EU Natura 2000 Integration Project (NIP) – the biggest project in Croatia related to fauna inventory, where we provided consulting services for field research and laboratory processing for collecting new inventory data for 11 taxonomic groups: Actinopterygii and Cephalaspidomorphi, Amphibia and Reptilia, Aves, Chiroptera, Decapoda, Lepidoptera, Odonata, Plecoptera, and Trichoptera.
Also, we have unparalleled experience in habitat mapping projects where we were practically a standard setting authority providing all what is needed for this complex activity. Apart from implementation of large scale habitat mapping of the entire territory of the Republic of Croatia 15 years ago (entire territory terrestrial and maritime) and fine scale mapping of practically all of Croatian protected areas (national and nature parks), we have provided training, ICT, RS and GIS support to a number of similar projects in neighbouring countries. Presently, we are doing this on a project in Turkey where we are providing technical assistance for strengthening the National Nature Protection System for Implementation of Natura 2000 Requirements.
Department of Natural Resource Management
Head of Department: Alen Berta, mag. ing. silv., CE
With over 130 completed projects, Oikon is a major provider of comprehensive forestry, agriculture and vegetation, carbon sinks, land use and land cover mapping services in Croatia.
Our services include development of Forest Management Plans (we have developed FMP for 15 % of Croatian private forests), large scale biomass and carbon sink calculations, feasibility studies (biomass, agriculture, forest and SRC), dendrochronology studies, etc.
Oikon has extensive experience and knowledge in land cover mapping. We have developed CORINE land cover (CLC) maps and change analysis including full reporting of the entire Croatian national territory for the reference years: 1980, 1990, 2000, 2006 (for which we received quality mark “very good” from the auditors that was by that time issued only once before in the history of CLC mapping) and 2012. Our methods follow and promote best practice criteria and guidelines and are aimed to ensure accuracy, quality and consistency of maps and accompanying databases.
We are capable for extensive, nation-wide field campaigns for relevant data collection as well for applying all relevant and actual Remote Sensing, GIS and geostatistical techniques and technologies (orthophoto, IR, multispectral satellite imagery, LIDAR), as prerequisites of accurate and cost-effective problem solving with required level of spatial and thematic detail.
Also, we are constantly widening and evolving our knowledge through formal and informal staff education, i.e. conferences, courses, summer schools. This is very important since GIS, remote sensing and other technologies are evolving so fast and we are very keen to keep our leading position in using that technology.
