Use of Depth-to-Water maps for site adapted planting (English)
Abstract [en]

Digital depth-to-water maps can be produced from a digital elevation model (DEM). Then GIS- based algorithms are used to calculate water flows and the depth-to-water index classes dry, fresh, moist and wet. The purpose of this study was to investigate the possibility to use depth- to-water maps for site adapted planting.

The results showed that use of depth-to-water maps for site adapted planting, roughly halved the proportion of improperly planted surfaces from an average of 9 % to 4 %. The variation in the values of proper surface decreased and the result became more even.. In addition, more pine than spruce was incorrectly planted. Without soil moisture maps, the proportion of improper pine and spruce was 66 % and 34 % respectively, and with soil moisture maps, the proportion of improper pine and spruce was 55 % and 45 % respectively. This shows that for regenerations planted without the depth-to-water maps, mostly pine was incorrectly planted, but for the regenerations planted with the depth-to-water maps, the proportions were similar for spruce and pine.

The conclusion from the results indicated that depth-to-water-maps can improve site adapted planting. By using the maps it is possible to get a good overview of the conditions and terrain variations of the planting sites.
