Per Milberg

Adjunct Professor

Biodiversity and species has always interested me and, consequently, how we should preserve and recreate natural environments.

Presentation

Two convictions have driven my research about nature conservation: 1) that we need to preserve as much as possible of Earth's biota; 2) that data collected for research of monitoring must be more efficiently used.

I want to contribute to the goals of nature conservation by providing knowledge about species and their occurrences that today is missing. The long-term goal is to convert own and other’s data into decision support for practical conservation work.

Butterflies thrive in grasslands surrounded by forest

For pollinating butterflies, it is more important to be close to forests than to agricultural fields. Results from a new study of 32,000 butterflies provide important knowledge about how to form the landscape to ensure the survival of butterflies.

Conservation Ecology Group

The management of species-rich grassland and deciduous forests have changed drastically over the last 80 years. Many species have become rare and endangered as the resources and habitat decreased. We study what is needed to preserve diversity.

Butterfly researcher receives Sweden’s largest teacher award

At the age of six, he began to collect butterflies. In primary school, he knew he wanted to be a butterfly researcher. Karl-Olof Bergman brings students and problems into nature. He is now rewarded with Sweden’s largest teacher award.
