Abstrakt
Tänapäeva kiiresti arenevas ühiskonnas kasutatakse järjest enam maailma maavarasid ja teisi ressursse. Jätkusuutlikkuse tagamiseks on tarvis leida tasakaal looduse kasutamise ja säilitamise vahel ning seepärast on mitmed riigid üle maailma hakanud oma kahjustunud või täielikult hävinenud ökosüsteeme taastama.
Töö eesmärgiks on uurida erinevaid niitude taastamise eesmärke ja nende saavutamise hindamist. Töös on kasutatud erinevaid artikleid, mis räägivad niitude taastamisest ajakirjadest Restoration Ecology, Biological Conservation ja Ecological Management and Restoration. Lõputöö on referatiivne.
Töö tulemusena leidsin, et enamjaolt on niitude taastamisel kasutatud kaheksat eesmärki. Nendeks on bioloogilise mitmekesisuse ja vegetatsiooni struktuuri taasloomine, ühe või mitme kindla liigi leviku soodustamine või takistamine, taimede ja loomade vaheliste suhete taastamine, võrdlusalaga sarnaste keskkonnatingumuste loomine, putukaliikide leviku taastamine, koosluse ruumilise struktuuri taasloomine, jätkusuutliku füüsilise keskkonna loomine. Mitmetel projektidel oli mitu eesmärki. Kõikide projektide puhul olid eesmärgid, taastamistegevused ja tulemuste uurimise viisid hästi paigas ning räägiti ka projektide tulemustest. Need tulemused viitavad sellele, et eduka niitude taastamise puhul (või ökoloogiliste taastamiste puhul üldiselt) on oluline terve taastamine väga korralikult planeerida ja lõpus on oluline ka tulemusi hinnata.
Lõputööd saab kasutada rohumaade taastamise projektide koostamisel ja ka üldisemalt ökoloogilise taastamise eesmärkide seadmisel.

In today’s rapidly changing society more and more of worlds natural resources are being used. There is a need to find a balance between the use and conservation of nature and hence a number of countries around the world have started to restore their damaged or completely destroyed ecosystems. This thesis aims to explore a variety of grassland restoration goals and the assessment of achieving these goals. The study uses a variety of articles from magazines Restoration Ecology, Biological Conservation and Ecological Management and Restoration, which talk about grassland restoration. The thesis is solely theoretical. As a result of this thesis I found that for the most part eight goals are used for grassland restoration. These include recreation of biological diversity and vegetation structure, enhancement or prevention of distribution of one or more species, restoring plant and animal interactions, creating similar environmental conditions with the reference site, restoring the spread of insect species, restoring the spatial structure of the community, creation of sustainable physical environment.Several projects had many goals. For all the projects targets and research methods were well established and restoration outcomes were also discussed. These results suggest that for successful grassland restoration (or ecological restoration in general) it is very important to properly plan the project and assess the results in the end. This thesis can be used for the preparation and goalsetting of ecological restoration projects.
