Description

The national wetland inventory (VMI) has for 25 years made inventories of Swedish wetlands that are situated below the mountain range. Wetlands have been defined in VMI as: "Land where water, for a large part of the year, is close to, in or above the ground, as well as vegetation-covered water areas. At least 50% of the vegetation should be hydrophilic, i.e. moisture loving, in order for it to be called a wetland area. An exception is sometimes dry-laid bottom areas of lakes, seas and streams. They count as wetlands even though they lack vegetation. " In total, VMI has invented 35,000 sites with a total area of 4.3 million hectares, which corresponds to 10% of Sweden's total land area. The purpose of the inventories has been to create a knowledge bank over the country's wetlands, which can be used for environmental monitoring and natural resource planning. By examining how and in what range wetlands are affected by human activities and by identifying valuable wetlands, their values can be preserved for the future. Inventory data was also planned to provide a basis for the authorities' handling of e.g. land drainage and logging. For practical reasons inventories has only been performed at larger wetlands below the mountain ranges. In northern Sweden inventories took place at all wetlands larger than 50 ha and in all wetlands in southern Sweden wetlands larger than 10 ha. All inventoried wetlands have been analyzed with aerial photos and remote sensing and has been classified according to the status of the nature values. A total of 12% of wetlands have also been visited in order to provide further knowledge. Based on the remote sensing, all wetlands were classified into one of the 47 different wetland types. Based on the spatial extent of wetland types, we have divided Sweden into five different marsh/bog-regions: Fell bog, Palsa bog, String bog, Raised bog and Pine bog/Beach wetland bog. The results of the VMI are regularly used by county administrative boards and municipalities and have been an important tool for national protection of wetlands. The regional inventories have been made by the various county administrative boards and the Swedish Environmental Protection Agency has acted as coordinator for the project. The digital data contains the delimitation of the VMI areas, a central coordinate and an ID (LOID). Via ID, you can extract data from access databases with information about species inventoried.

Data Records

The data in this occurrence resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 531,075 records.

This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.
