for 81% of the total value. The extraction of row materials (mainly timber) has 3,303
BGN/year, which is only 11% of their total value. The excessive timber production
menaces some of the regulation services, which could have negative effect in the
future. The forest ecosystems in the temperate subhumid landscape type have higher
regulation value because of their role in the flood-risk reduction (Nikolova et al.,
2008
). This value is calculated to be 4.7 million BGN/year, which is almost half
