This paper inquires into the questions related to endangered habitats and species, as well as that of factors threatening biodiversity, in Romania, by analysing existing opinions of biodiversity institutional stakeholders. The research applies a combination of qualitative social science (participatory) approaches and quantitative tools as a means for understanding biodiversity related issues in Romania. Heterogeneity of opinions of biodiversity institutional stakeholders, concerning endangered biodiversity and its threats, are analysed. Stakeholders' perspectives are identified through characterization of opinion groups and discursive analysis. Key factors influencing the attitudinal diversity are examined. Research outputs reveal the diversity of existing stakeholders’ views.
