The mapping is intended as a basis for analysis in connection with spatial planning, green planning, climate adaptation and monitoring that can be used by municipalities, county administrative boards, companies and authorities.
Interim target for ecosystem services in the built environment
The National Board of Housing, Building and Planning is tasked with following up the interim target for ecosystem services in the built environment within the environmental objectives system. The interim target means that by 2025, a majority of municipalities must make use of and integrate urban greenery and ecosystem services in urban environments in planning, construction and management in cities and urban areas.
The Swedish National Board of Housing, Building and Planning is also tasked with coordinating the national climate adaptation work for the built environment. The assignment addresses issues relating to planning documents to facilitate work on climate adaptation in the built environment.
Urban trees relevant in climate adaptation work
Trees contribute many different ecosystem services, among other things, they are of great importance for regulating local climate and stormwater management. Planning data that quantifies the presence of urban trees is considered relevant in the climate adaptation work carried out by municipalities, county administrative boards and other actors. This forms the basis for the development of this product, which shows elevated vegetation in 1 x 1 meter resolution and can be used to analyze tree cover in urban areas with more than 5000 inhabitants. The tree cover is derived by calculating the vegetation index from orthophotos and combining it with elevation information from surface models. Supplementation has in some cases been made with information from National Ground Cover Data in combination with data from the latest national laser scanning.
Tree cover statistics for urban areas and districts
Within the assignment, Metria has also produced compiled tree cover statistics for urban areas and urban districts. Tree cover grids and compiled tree cover per urban district can be found on the Swedish National Board of Housing, Building and Planning's map service. The grid data can also be ordered via the National Board of Housing, Building and Planning's FTP service.
