Protected forests are an essential safeguard for settlements and infrastructure against floods, mudslides and avalanches.
A well-rooted forest stabilizes soils, increases water retention and reduces erosion - at a fraction of the cost of engineered barriers.
Our autonomous heavy-duty drones deliver precise seed distribution on even the most challenging slopes.
A careful mix of tree, shrub and herb species ensures rapid, effective erosion protection.
Various tree, herb and shrub species were planted on two hectares to secure a steep slope following windthrow.
Soil type: Rendzina, Bavarian Limestone Alps
Old-growth canopy: Fi100 (spruce)
Species planted: service tree, sand birch, mountain ash, elderberry and wood willow
After the first year, 12,500–13,100 seedlings of trees and shrubs were counted per hectare. In addition, there was countless fireweed.
Initially, no birch trees could be found. These often lie dormant for 1-2 years and germinate as soon as ecological conditions are favourable.
Deer elder: 4.900 - 5.100
Serviceberry: 4.000 - 4.200
Rowan: 3.600 - 3.800
