2. Two parallel and integrated inventories
Field inventory: Plots och transects
Aerial photo interpretation: Polygones, points and transects

1 km x 1 km

3. Circular plots with different radius
20 m radius – 1257 m2 Cover of main habitat type Cover of trees Land use Impact Alpine habitat type
10 m radius – 314 m2 Shrubs Field layer Bottom layer Ground description Detailed tree measures Some lichens
3,5 m radius – 38,5 m2 Detailed data from trees Droppings from animals
0,28 m radius – 0,25 m2 Field layer Bottom layer Presence of herbs Presence of mosses Presence of lichens

10m

4. Line-crossing inventory
A = area of the inventory area
m = number of cross-points
L = total length of inventory lines

5. A posteriori classification
Mixed / agricultural landscape
Mountainous / wetland landscape

6. Application of NILS data
Documentation, assessment and refinement of the environmental quality objectives
Background data for national policy and strategic planning
International reporting (incl. Natura 2000)
Platform for other environmental monitoring
Platform for (applied) research: data, technology, methodology
Dataforum
Empirical approach
On demand – requires developed sector cooperation
