A pair of roe deer (Capreolus capreolus) first settled in Vanhankaupunginlahti in 2011. Since then, the area’s deer population has been growing year on year, with the numbers of calves born per year already reaching double digits.
Helsinki’s roe deer have become quite fearless, and they have also spread to the reed beds bordering the duckboards to Lammassaari island. They can occasionally be seen during the day as well. Other roe deer areas in Helsinki include Vallisaari island, Central Park and Östersundom.
