20th century Betula pubescens ssp. czerepanovii tree- and forest lines in Norway

Latest version published by University of Oslo on Jan 27, 2021 University of Oslo

Georeferenced tree- and forest line data has a wide range of applications and are increasingly used for e.g. monitoring of climate change impacts and range shift modelling. As a part of a research project, registrations of previously re-mapped tree- and forest lines have been georeferenced. The data described in this paper contains 100 registrations of Betula pubescens ssp. czerepanovii throughout Norway. All of the re-mapped tree- and forest line localities are georeferenced, elevation and exposition is given, elevational and spatial uncertainty is provided, and the re-mapping methods are explained. The published data has been gathered from 1928 until 1996, but has until now been missing spatial coordinates. The entries contain 40 tree lines and 60 forest lines. The entire material is stored and available for download through the GBIF server.
