Spring
March
Dyrehaven’s puddles in the deciduous forests and on the plains are swarming with fairy shrimps at this time of year. These are several-centimetre-long crustaceans, so-called branchiopods, which are related to water fleas and are relatively rare in Denmark. Dyrehavsbakken amusement park opens on the last Thursday in March, and according to tradition a cortège of around 4,000 motorcycles drive from Nørrebro in Copenhagen up Strandvejen to Klampenborg to celebrate the opening.
April
The noctule bats emerge from their winter hibernation. There is a large number of bats in Dyrehaven due to the many old hollow trees. Blooming and leafing time – first the beech comes into leaf, then the oak.
May
This is when the results of the rut show: about 700 fawns are born and hide in the tall grass for the first days of their lives until they can follow the flock of females that graze with their offspring. Flock sizes can vary from only a handful of animals to hundreds of fallow deer in one flock on Eremitagesletten. The male red deer (stags) keep to themselves until the rutting period begins again. The hawthorn blossoms.
Summer
June
Every three years, the Royal Danish Theatre arranges a large open-air performance in Ulvedalene. In 2013 there were performances of "Robin Hood". On the first Saturday in June it is tradition that people bring their picnic basket, dress in white and hold a white picnic near the flowering hawthorn bushes at Hvidtjørnesletten inside the Springforbiporten gate.
July and August
The deer’s new antlers have grown out, and they “fray” them against the bark of the trees to remove the skin that has protected the antlers during growth.
