Alpine pioneer plants in soil bioengineering for slope stabilization and restoration : results of a preliminary analysis of seed germination and future perspectives
Stabilization of slopes subject to landslide by measures with low impact, such as those of bioengineering, is a topic of interest. The use of scarcely studied alpine pioneer plants could contribute to innovation in soil bioengineering and restoration ecology but to use them, knowledge of the ex situ...

Stabilization of slopes subject to landslide by measures with low impact, such as those of bioengineering, is a topic of interest.
