Due to the active forest harvesting in Estonia, there is a heated discussion about its effects on climate and natural habitats. Because of that we wanted to study the biomass and vegetation of forests in different growth stages. The aim of the study is to note the vegetation and biomass of the forest and find how the formerly cut recovering forest is recovering by comparing its vegetation to an older pine forest. For that we did fieldwork in five different study sites on the shore of the Baltic sea in Matsi, Pärnu County, where we measured tree height, trunk circumference, and studied the vegetation. According to the research, the biomass and the amount of stored carbon does not vary a lot in one forest; the biomass in a forest can be up to 26 times more than in a herbaceous field, and that formerly cut recovering forests have mostly deciduous species even if the cut forest used to be mostly evergreen. To extend the study, the methods should be improved by making them more clear and concrete. In addition, the fieldwork can be carried out in other forests in Estonia and if a few more measurements were added, conclusions could also be made on the topic of forest recovery and that can help to make even better decisions about cutting or preserving forests.

Congratulations, an interesting study on the biomass deposition on recovered forests. Did you find more information about herbaceous fields recovering to forests? Interesting study, keep up the good work! Would be interesting if you can continue this important study for soil conservation.
