44% of Bulgaria's territory is protected and the country has 92 protected habitats.

Omissions

• The exact figure of 44% of protected territory does not appear in the sources found; the EEA states 'about 40% of Bulgaria's land area is protected' and explicitly notes this is 'likely to be an overestimation, as it includes state game...' areas.
• The Natura 2000 network alone accounts for approximately 34.5% of Bulgaria's territory (ResearchGate / Bulgarian Academy of Sciences), so the 44% refers to total protected designations including national protected areas.
• The number of protected habitat types is reported variously as 90 (Bulgarian Academy of Sciences) and 96 (Bekchiev, 'The protected areas in Bulgaria'); the claimed 92 lies within this range but is not directly published.
• Sources consulted are mainly secondary/academic; the EEA country page is the closest to a primary official source.
