Eestis leiduvate, ainulaadsete, suure bioloogilise mitmekesisusega poollooduslike koosluste pindala
on viimase poolsajandi jooksul drastiliselt vähenenud. Selle põhjused on kollektiviseerimine,
maaparandus, loomakasvatuse intensiivistumine, väiketalude kadumine, maade kultuuristamine ja
suurte põllumajandusmasinate kasutuselevõtmine. Selleks, et antud koosluste pindala enam ei
väheneks ega lõplikult ei kaoks on Keskkonnaamet läbi viinud mitmeid erinevaid projekte. Antud töö
eesmärk on määrata kindlaks suure taastamisväärtuse ja potentsiaaliga puisniidud mis asuvad Saare
maakonnas. Selleks on kasutatud Pärandkoosluste Kaitse Ühingu, Natura 2000 elupaikade ja
Keskkonnaregistri Poollooduslike koosluste andmebaasi. Selliste puisniitude väljaselgitamiseks on
nende andmebaaside alusel koostatud uus, MapInfo kaardikiht. Selle kaardikihi põhjal on tehtud
esmased taastatavate alade valikud. Nendel projektialadel paiknevate kinnistute omanikele on
saadetud Pärandkoosluste Kaitse Ühingu poolt kirjad koostööpakkumise ja projektis osalemise
võimaluste tutvustamisega. Saare maakonnas on moodustatud 25 projektiala ja saadetud
koostööpakkumine 501 maaomanikule. Kokku on antud töö raames välja valitud 1311 ha
potentsiaalselt taastatavaid väärtuslike puisniite. Lisaks on valitud puisniitude taastamiseks ja
edaspidiseks hooldamiseks kõige sobilikum tehnika. Peale maaomanikelt nõusolekute saamist
nende kinnistutel puisniidu taastamiseks koostatakse Keskkonnaameti poolt rahastustaotlus
Euroopa Liidu Nature fondi. Antud projekti lõpptulemusena on kogu Eestis taastatud ja hooldatud
ca 1000 ha väärtuslike ja ainulaadseid puisniite. Käesolev puisniitude taastamise projekt on
analoogne juba töösolevale LIFE to alvars ehk Elu loopealsetele projektile.
The area of unique, highly biodiverse semi-natural habitats in Estonia has drastically reduced over the last half a century. This is due to collectivization, soil improvements, livestock production intensification, disappearance of small farms, cultivation of the land as well as the use of big agricultural machinery. The Environmental Agency has carried out various projects to stop the areas of these habitats to decrease even more or to disappear completely. The aim of my thesis is to identify the wooded meadows with big restoration value and potential located in Saare county. Different databases by Estonian Seminatural Communities Conservation Association, Natura 2000 habitation and semi-natural community database by Environmental Registry has been used for this. In order to identify the wooded meadows, the data from those databases have been compiled into a new MapInfo map layer. Based on this map layer, the initial selection of the wooded meadows to be restored has been made. A letter offering coworking opportunity and information about participating in the project, has been sent to the land owners, whose land is in the project area, by the Estonian Seminatural Communities Conservation. In Saaremaa, 25 project sites has been formed and a letter of coworking has been sent to 501 land owners. In total 1311 ha of potentially valuable wooded meadows to be restored has been identified in this work. Additionally, a recommendation for the technology best suited for restoration and future maintenance has been made. After receiving the letter of consents from the landowners in whose land the wooded meadows are to be restored, Estonian Environmental Agency submits an application for funding to the European Union’s Nature Fond. As a result of this project, around 1000 ha of valuable and unique wooded meadows will be restored and maintained in the whole of Estonia. This project of restoring the wooded meadows is similar to the already established LIFE to Alvars project.
