One-year ornithological research and report for wind power plant Jelenje

Project name: One-year ornithological research and development of an ornithofauna report for the needs of the environmental impact assessment for wind power plant Jelenje, Group 1

Client: HEP – Proizvodnja Ltd.
Period: 01/2018 – 02/2019
Location: Croatia


The one-year research was conducted with the aim of determining the significance of adverse impacts and adverse cumulative impacts of the planned wind farm on the local ornithofauna and on the entire population of endangered bird species in the Republic of Croatia.

For the purposes of the research, the following methods were used: vantage point (observation of overflights from fixed points), line transect, monitoring of nesting predators, tape lure of nocturnally active species and non-standardized search of the area.

Based on the data obtained from the implementation of the line transect and night tape luring, the population density of songbirds and nocturnally active birds in the narrower and wider project area was calculated.

Using data on the manner, intensity and duration of migrations of birds of prey and migratory species, the risk of collision of individual species was calculated using the collision risk model (Scottish Natural Heritage – SNH, 2014).
