The winter 2020/11 was an harder winter, coming as it were after a long succession of mild ones.
it was, at least for the park, the most extreme by any standard but it was protracted and colder in average.
It put a strain on the bird population and we organised some feeding for them.
Here even small area of wilderness have helped a lot. They becomes a natural refuge and allow a much larger survival rate for a variety of organisms. It also help in recovering when spring arrives.
