Knowledge of species, interest in nature, and nature experiences are the factors that best promote interest in and understanding of environmental issues, biodiversity and sustainable life. The aim of this study is to investigate how well student teachers identify common local species, their interest in and ideas about species identification, and their perceptions of the importance of species identification and biodiversity for sustainable development. Totally 456 student teachers for primary schools were tested using an identification test and a questionnaire consisting of fixed and open questions. A combination of quantitative and qualitative

methods was used to get a more holistic view of students’ level of knowledge and their preferred learning methods. The student teachers’ ability to identify very common species was low, and only 3 % were able to identify most of the tested

species. Experiential learning outdoors was suggested by the majority of students as the most efficient learning method, followed by experiential learning indoors, project work and experimental learning. They looked upon the identification of plants and animals as ‘important’ or ‘very important’ for citizens today and for sustainable development. Likewise, they looked upon biodiversity as ‘important’ or ‘very important’ for sustainable development. Our conclusion is that teaching and learning methods for identification and knowledge of species and for education of biodiversity and sustainable development should always include experiential and

project-based methods in authentic environments.
