Dataset fields

virkemiddel

Measure

The project's primary land-conversion measure.

status

Status

The project stage recorded in MARS.

tilskudsordning

Funding scheme

The recorded grant or funding scheme.

areal_ha

Project area

The recorded project area in hectares.

ansoegningsrunde_aar

Application round

The year of the recorded application round.

kvaelstofeffekt_t

Nitrogen effect

Nitrogen effect in tonnes under MARS accounting rules. Zero may reflect baseline accounting or no effort requirement; it is not a measurement of the project’s environmental effect.

udtagningseffekt_ha

Land retirement effect

The recorded land retirement effect in hectares.

skovrejsningseffekt_ha

Afforestation effect

The recorded afforestation effect in hectares.

forundersoegelsestilsagn_dato

Pre-investigation commitment

Date of the recorded pre-investigation commitment.

etableringstilsagn_dato

Establishment commitment

Date of the recorded establishment commitment.

anlaegelse_dato

Construction date

Date when the project was recorded as constructed.

updated

Updated at source

Most recent update recorded in the source data.

Limitations and responsibility

A project may be at pre-investigation, establishment-commitment or constructed stage. The layer is not a total of completed restoration, and records may have changed since the snapshot date. Nitrogen effects follow MARS accounting rules and are not measurements at the site. Projects included in the VP3.2 baseline or in subcatchments without an effort requirement are shown with zero nitrogen effect. This does not necessarily mean the project has no environmental effect.
