Vulnerable flora species in Natural Park Bucegi After soil reaction analysis revealed, that most of the species are weakly acid-neutrophils (R4—50%) and acid-neutrophils (R3—17%), which reflects the existence of favorable conditions for plant grow. In strong leachate territory with acid substrate are growing acidophilus species (R2-11%). Fig. 5 Ecological factors analysis, humidity, temperature and soil reaction The percentage structure of vulnerable vegetation floors of Bucegi Natural Park is distributed as follows: 39% alpine floor, 22% alpine and subalpine floor, 17% subalpine and 22% subalpine and mountain floor. Biodiversity conservation measures of Bucegi Natural Park According to the National Agency of Environment Protection (ANPM), Bucegi Natural Park includes the following habitat types: freshwater habitats, shrubbery and meadows habitats, rocks habitats and forest habitats. From each habitat type, must been taken a number of measures for nature conservation, provided by Natura 2000 network. Natural and anthropic factors threaten the existence of many plant species. From natural factors, the most common are: unfavorable habitat, natural disasters, sudden climate change, the competition with other species more robust, parasitic fungi as biological degeneration, slow seed germination, etc.. Anthropic factors are the most important, such as human settlements, industries, pollution, tourism, drainage, flooding, deforestation, fires, road construction, landfills, etc.. 1. Protection measures for forest habitats. Some of the measures taken for forest protection and conservation of nature are: avoiding transport of timber by dragging, activity break in rainy periods, wood storage must occupy very small areas, preferably at the edges of the road, forestry rules promote natural regeneration in forest habitats, in priority forest habitats, building roads is restricted or prohibited, grazing area is limited, etc. 2. Freshwater habitats require a series of protective measures: avoid building forest roads on riverbed, avoid any kind of vehicle movement on the river shore and riverbed, temporary deposits of harvested wood cannot be established on riverbed. Also is prohibited to abandon branches or other materials and drainage are prohibited or restricted; herbaceous vegetation on mountains rivers should be conserved by stopping grazing around springs and the tourism control activities. 105
