Welcome to the Tree gateway

The Tree Gateway is a web-based database for collecting reports on veteran trees and other trees worthy of protection. Especially old trees, giant trees, hollow trees and pollards are of interest.

The information is based on citizen science as well as work done by institutions and authorities, and open to anyone who wishes to contribute their observations. The Tree Gateway is developed and run by the Swedish Species Information Centre (ArtDatabanken), on commission by the Swedish Environmental Protection Agency (Naturvårdsverket).

During 2009 import of larger data sets, gathered through large scale surveys conducted by the County boards, will be executed. The trees can be monitored and new observations on recorded trees can be made by volunteers or professionals. Of course, also new trees can be added. The data is presented in tables as well as on maps and satellite images. Data can be exported for other purposes.

The aim by collecting and presenting information about valuable trees is conservation of biological diversity, but also care of other public interests. We hope the information will be used in land management and society planning.
