The project was supported by the EU LIFE+ program and Environmental Investment Centre. The implementers of the project were Environmental Board, Estonian University of Life Sciences, University of Tartu and Estonian Seminatural Communities Conservation Association.

Traditionally, those were village pastures but without grazing, alvars overgrow with junipers and pine trees, and the biodiversity typical to open pastures disappears. As a result of these changes, by 2010, only a small portion of Estonian alvar pastures had preserved the look and diversity of this habitat type. To achieve a significant positive change in the status of the habitat, many large alvar grassland areas had to be restored. In 2012 the most valuable alvar grasslands in 2500 hectares of protected areas were cho- sen based on an analysis by scientists, and the search for the necessary resources for the restoration works and the involvement of private land owners was initiated. In 2013, the Environmental Board in cooperation with the University of Tartu, the Estonian University of Life Sciences and the Estonian Seminatural Community Conservation Association sub- mitted an application for the “LIFE to alvars” project to the European Commission’s LIFE + fund. In autumn of 2014, we began restoring alvar grasslands using machinery for the first time in Estonia. Before the alvar project, seminatural communities in Estonia were predominantly being Annely Holm restored manually using chainsaws and brush cutters. Already during the Project Coordinator, Environmental Board planning stage of the project, it was clear that manual restoration was too slow and expensive to be able to turn 2500 hectares of overgrown alvar grasslands into pastures within the project budget and in the frames of given time frames. To create suitable conditions for grazing reintroduction, restoration works on alvar grasslands involved the thinning of juniper thickets, cut- ting down pine trees and establishing cattle fences. During the works, common forestry machinery and equipment were used such as a harvester, a guillotine and a chain swipe mower fitted to an excavator, a forwarder, etc. Using machines enabled the alvar grasslands to be restored signifi- cantly faster and cheaper compared to manual work. Thanks to the use of machinery, it was possible to restore 2500 hectares of Estonian alvar grass- lands in only five years. Monitoring results have confirmed that mecha- nised restoration does not affect the biota of alvar grasslands negatively and that the typical species will return after the end of the restoration works even faster than expected. By today, this methodology is also widely used in the restoration of other meadow areas as it allows to restore the favourable condition of habitats faster and cheaper, and to achieve the respective nature protection goals.

Approximately 600 private land owners and 60 farmers were involved in the project. Only through a cooperation between the local farmers and land owners is it possible to ensure long-term maintenance of the project’s results in terms of ongoing grazing the restored areas. Having been part of the creation of the idea for the project, and the preparation and implementation of the project, I recommend the planners and implementors of future nature protection projects to plan these ini- tiatives on a large scale and boldly, because the diversity of our nature is our country’s greatest asset and a basis for the preservation of life. I would also like to thank everyone who has contributed to the alvar grassland Photo: Bert Holm restoration project one way or another!

Therefore, the project was carried out in Western Estonia, mainly on the islands of Saaremaa, Hiiumaa and Muhu in respect to the historical presence of the most valuable and massive alvar grasslands. In total there were 25 project areas at 16 different NATURA 2000 sites involved. In each project area practical habitat restoration and grazing reintroduction was carried out. However, the area involved in restoration and grazing reintroduction varied between project areas ranging from 11...330 hectares per site. The general aim of this project was to restore the most valuable, but overgrown alvar grassland areas on 2500 hectares together with ensuring the following continuous traditional management of these areas and ris- ing the awareness of different interest groups influenced by the project implementation. This project involves alvar grasslands situated on both private and public land and the emphasize was on a thorough involvement of private land-owners. Therefore, large effort has been put on direct in- volvement, fostering the multilevel cooperation, training, dissemination and increase of public awareness. Many of the project areas are visited by tourists. By connecting educational and recreational side of the alvar grasslands, it was also possible to increase the knowledge of the general Photo: Ants Animägi public about the importance of maintaining this habitat type in Estonia.

Less than 100 years ago the total area of grazed alvar grasslands was around 43 000 hectares. During the last century alvar grass- lands have decreased significantly in their total area in Estonia due to cessation of traditional of management and subsequent overgrowing. In 2013 only around 2000 hectares i.e. less than 30% of since preserved and less than 5% of the historical area of Estonian alvar grasslands were under annual management. With the cessation of livestock grazing and beginning of overgrowing, the abundance of habitat specialist species starts to decrease, whereas gen- eralist species from surrounding landscapes start to invade the habitat. In overgrowing grasslands, species richness starts to decrease gradually, with abrupt decreases following when the shrub cover exceeds 75%. Due to changing light conditions, shade tolerant species gain the dominance, while light-demanding grassland species go locally extinct. However, before it is possible to reintroduce grazing to the overgrown sites, it is necessary to restore the habitats i.e. cut down trees and reduce the shrub layer to the coverage of up to 30% which is a resources consuming task for what the sufficient funds have not been available so far and large-scale restoration methodology was not tested in Estonia.

However, before it is possible to reintroduce grazing to overgrown sites, it is necessary to restore the habitats i.e. cut down trees and reduce the shrub layer to the coverage of up to 30%. So far the main problem in meadow habitat restoration overgrown with bushes or trees was that those areas have been tried to restore gradually, reducing the overgrowth coverage step by step without immediate grazing reintroduction and applying slow manual restoration techniques. This usually resulted in the situation where the newly restored area covers with regrowth of trees, bushes and reed as the restoration process was too slow. In terms of novelty we started to use the chain swipe mower fitted to an excavator and the common
