This paper is focusing on the mountain pines (Pinus mugo), the juniper (Juniperus communis) and the
rhododendron (Rhododendron kotschyi) common habitats, the establishing the methods of maintaining or
protecting of non-degraded populations, and the restoration methods of degraded populations, within the alpine
habitats conservative management belonging to the Retezat National Park.. Between the natural and artificial
regeneration methods applicable to restore the degraded mountain pines populations, the regeneration by
plantation seems to be the only reasonable method, having in view that the natural regeneration is difficult and
require long period of time. This study begins with presentation of the preservation plans of the unique natural
landscape, named Retezat National Park, located in Meridional Carpathians (Romanian Southern Carpathians)
and continues with the description of the natural distribution of the mountain pines (Pinus mugo) populations
and their associated herbaceous and woody species in the Retezat National Park. The renaturation with mountain
pines seedlings, within the case study regarding an ecological restoration in Retezat National Park, methods,
remarks and predictable results are presented. Also, the study offers details concerning the ecological principles
of the destroyed habitat’s artificial regeneration, such as: the planted area, seedlings, seedling production and
their transportation to the planting area and effective plantation
