Spring has come a long way in the southern parts of the country, while further north it is still winter and snow. Now the Swedish Botanical Association and the Swedish University of Agriculture (SLU) are asking the public for help in reporting the signs of spring to Vårkollen during the Walpurgis weekend.
Vårkollen, which is a citizen research project in which volunteers and professional researchers collaborate, was conducted for the first time in 2015. The results are compared with observations made 150 years ago by a network of observers.
“That way, we have the opportunity to see what effect today’s climate has on the plants,” says Ola Langvall from SLU and coordinator of the Swedish Phenology Network in a press release.
Since Vårkollen started nine years ago, it has been seen that many of the plants that are observed emerge earlier in many places compared to 100–150 years ago.
The result will be published on May 2.
