The spotlights in question have a colour temperature of 6500 K which is considered detrimental to local wildlife – birds, nocturnal insects, bats, and even plants. They were installed on palm trees in the park and turned upwards, making them a light pollutant of the night sky, reports the Croatian Astronomical Union.
The Croatian Astronomical Union has been collaborating with Jelsa Municipality and the local tourist board for over a year in order to help Jelsa achieve high standards of protection against light pollution. Jelsa is now a step closer to becoming the first International Dark Sky Community in Croatia and south-east Europe at large.

In December 2021, the International Dark-Sky Association (IDA) accepted the motion of Jelsa Municipality to be declared an International Dark Sky Community. A few days ago, IDA delivered a favourable opinion and it’s now only a matter of time before Jelsa is granted the coveted title.
As defined by IDA, an International Dark Sky Community is ‘a town, city, municipality or other legally organised community that has shown exceptional dedication to the preservation of the night sky through the implementation and enforcement of a quality outdoor lighting ordinance, dark sky education and citizen support of dark skies. Dark Sky Communities excel in their efforts to promote responsible lighting and dark sky stewardship, and set good examples for surrounding communities.’
