From: Tree stumps — an important but undervalued dead wood pool
Data from the NFI5 stump inventory for 6961 inventoried stumps on heights measured on the upslope and the downslope facing sides separately for conifers, broad-leaves, and undetermined species stratified by five forest regions and three elevation classes (≤ 600 m, 601–1200m, > 1200 m). The forest region (or production region) is used in the Swiss NFI to identify five regions with relatively homogeneous growth and wood production conditions: 1, Jura; 2, Plateau; 3, Pre-Alps; 4, Alps; and 5, Southern Alps
