The land-use history in the region has led to a significant reduction of the Hyrcanian forest. Considering the previous loss of habitat and the threats facing the World Heritage, it is evident that the current state and future trend of most biodiversity values is of high concern. The negative trend can only be stopped by implementing all the commitments by the State Party and the recommendation from the World Heritage Committee to protect the site. A failure to safeguard the site's biodiversity values will have a negative impact on crucial ecosystem services for the whole region.
