Not all voles are the same
Surely you have heard something about voles. The most famous is probably Common vole, which is frequently accused as a culprit for its taste for agricultural crops. But not all voles are the same. Hidden in the wetlands of the Danubian Lowland, the Pannonian root vole lives. Unlike some of its relatives, pannonian root vole doesn’t like crops, but it is an important part of the wetlands habitat.
The project LIFE Microtus II follows a previous successful project implemented from 2010 to 2016. It is focused on the protection of this priority species of European interest through restoring its habitat and building bio-corridors. Pannonian root vole is a protected species that lives in the vicinity of rivers, wetlands and wet meadows. In addition, its habitat is disappearing due to intensification of agricultural production, forestry and watercourse regulation. By protecting a rare species, we protect not only the animal itself, but also many other species that live in the same habitat. The Pannonian Root Vole is thus an umbrella species that protects other wetland species as well.

We inaugurated the revitalised end of the Čiližský stream
On Friday 26.7.2024 we completed the revitalization of the lower part of the Čiližský stream with the final dig. It was done following a number of measures we have taken to gradually improve the flow of this important 35 km long stream in the Danube region.

Mossy Earth released another video about our wetland restoration in Istragov
Mossy Earth has released the 7th video about our joint revitalization of the Istragov wetland. Duarte returned after 2 years to check what impact this revitalization had on the fauna and flora.

Microtus II visit in Šumava
In May, together with the stakeholders of the Microtus II project, we went to get inspired to the Šumava National Park. The study tour was attended by representatives of the Ministry of the Environment (MŽP), Slovak Water Management Enterprise(SVP), Water Management Construction Enterprise (VV), Water Management Research Institute (VÚVH) and the Dunajská Streda district office.…

The members of the project steering committee met again after a year
On Wednesday, November 29, a meeting of the project steering committee members took place. Thirteen participants attended the meeting, including seven members of the steering committee. Together, we visited the successful implementation of project activities in Čiližské močiare.

SCI Čiližské močiare just got a new “pond.”
Competition for water is high in the Danubian Lowland, especially during spring and summer. During those seasons, the water from the melioration canals is used to irrigate the surrounding fields.

Workshops for stakeholders in collaboration with the Nadácia Telekom at the Pontis Foundation
In the second workshop on cleaning the Čiližský stream and plans for the restoration of adjacent wetlands, we completed the removal of waste in the vicinity of the former landfill at Veľký Meder. After opening the natural mouth of the Čiližský stream and restoring the flow to the stream, we prevent the movement of waste downstream

We saved the wetland
Thanks to 1076 supporters, we managed to collect the targeted amount. We are very happy that in approximately 10 months we managed to collect up to 100,000 euros and even a little more for the purpose of nature protection - saving the wetland in highly productive agricultural land.

Great video about our wetland restoration in Istragov is released
Mossy Earth made a great video about our common project- wetland restoration in Istragov. About the wetland and its life and biodiversity and how it is evolving within the first year after first flooding. If you wanna check their professional video-production, check this great and well explaining video

Visiting Pannonian root voles with our stakeholders
In September 2022, the first Microtus II study tour, previously postponed due to the pandemic was finally organized. Together with our stakeholders, we explored the wetlands of Balaton-felvidéki National Park in Hungary. Around Lake Balaton

Microtus II team networked in the Netherlands
The project team (BROZ and PRIF UK) headed to explore the Netherlands in September 2022. The reason is that a relative of the pannonian root vole lives here. Another endemic subspecies – Microtus oeconomus arenicola has found a refuge there after the ice age.

Tidying up the Čiliž brook
On Saturday 19th of November, together with volunteers we have started working on tidying up the Čiliž brook. The brook flows nearby a landfill in Veľký Meder. The landfill had been closed for quite some time, however, the access was closed only recently.

Microtus minibus in Slovakia
In august, we borrowed a Microtus minibus from our Hungarian partner Pisztráng Kör. The minibus is an outdoor mobile laboratory for all ages. The van is equipped with all necessary tool to be used by all curious explorer for research of different biotopes and its residents.

LIFE Mission
Recently an annual inspection of the Microtus II project activities, known as Monitoring Mission has taken place. The mission is conducted by an external monitor is European Commission.

Istragov wetlands restoration
We have prepared the first plan for the restoration of the Istragov wetlands, with the aim of year-round presence of water in Istragov.

Workshop in the Danube floodplains
In the Danube floodplians, we organized a workshop for experts from various fields of nature protection, agriculture and energy.

Even Pannonian root vole has the boundaries
On the borders of ÚEV Čiližské močiare, the home to a large population of the Pannonian root vole, we planted a tree line of hawthorns, oaks and alders and completed it with an agate stakes.

Connection of wetlands by Čiližský potok brook restoration
As part of the LIFE Microtus II project, we will modify the end of the Čiližský potok brook so it will flow freely and create new wetlands on an area of approximately 40 hectares.

Root vole monitoring continues
This year’s autumn monitoring has yielded gratifying results. We found that the number of voles in the locality near the village of Čiližská Radvaň increased compared to previous years.

Education in the wetlands
Wetlands are used directly for educating the public. Microtus minibus runs in Hungary. In Austria you can sail among the reeds.

Restoration of bio-corridors and wetlands on Istragov
As we announced in February this year, we started with the creation of biocorridors, the so-called ‘Highways’ for root voles, which will allow them to move more easily between locations.

Mowing of meadows in NP Neusiedler See-Seewinkel
In neighboring Austria, on the shores of lake Neusiedler, the work on restoration of Pannonian root vole habitat is also in progress.

By Minibus to Microtus
Our Hungarian project partner, Pisztráng Kör, obtained a minibus, so called Microtus Minibus, for the purposes of this project.

Searching for Root Vole Biocorridors
Since the beginning of the year, we launched a regular field monitoring of potential biocorridors – „highways“ for the root vole together with the project partners, the Faculty of Natural Sciences of the Comenius University in Bratislava and the State Nature Conservancy of the Slovak Republic.

Wetlands and Their Significance
A wetland could be characterized as a habitat, existence of which is conditioned by water. This territory can be soaked with water on a permanent or seasonal basis.

Root Vole Monitoring
The Teriologists* from the Faculty of Science, Comenius University in Bratislava have been engaged in root vole studies for more than ten years. The root vole has been researched in the field as well as the samples in the laboratory using molecular methods.

Management of root-vole localities
In march 2020 we removed young poplars from root-vole habitats in order to maintain favourable habitat status of this endemic species.

Main objective:
The project LIFE Microtus II is primarily focused on the restoration of habitats for the root vole (Microtus oeconomus mehelyi) through of one-time conservation measures to restore or modify wetland habitats such as swamps, marshes, bogs, wet meadows, naturally flowing and still water places, and reintroduction of sound sustainable management. Project measures will create habitats for root voles with an area of 580 hectares.
Specific objectives:
- Restoration of selected wetland habitats
- Restoration of selected wet meadows habitats and buffer riparian zones between wetlands and arable land
- Creation of bio-corridors and stepping stones for target species
- Acquisition of relevant scientific data on target species, especially on genetic structure of the population and quite new threat of competition with invasive species
- Creation of conditions (infrastructure and capacity) to reach favourable state of wetland habitats and ensure long-term sustainable use of their services in cooperation with various local stakeholders
- Increase the awareness of stakeholders and public on target species, conservation measures and importance of wetlands ecosystems
Central European tundra vole (Microtus oeconomus mehelyi) or a root vole is a glacial relict of a subspecies Tundra vole (Microtus oeconomus). Tundra vole is a species with holarctic distribution, it is found in the area from northern Finland, eastern Germany, through Poland, Belarus, northern and central European part of Russia to the eastern Alaska. Isolated relict populations were found in Netherlands, southern Scandinavia, Finnish coastal areas and in the western part of the Pannonian Basin.
The European population consists of several subspecies: Microtus oeconomus ratticeps in the north of Russia; Microtus oeconomus medius in Scandinavia; Microtus oeconomus stimmingi from Germany through Poland to Russia; Microtus oeconomus finmorchicus in Norway and Vesterålen, Microtus oeconomus arenicola in Netherlands and Microtus oeconomus mehelyi in the western part of the Pannonian Basin.
The occurrence of the subspecies Microtus oeconomus mehelyi is restricted to locations around Neusiedler and Seewinkel lakes in Austria that are directly connected to Hungarian ones near Fertő lake. Another population lives in the nearby system of fragmented wetlands Hanság east of the lake. Isolated population is found around Balaton lake; small populations live on Danube island Szigetköz. From there, the area of species distribution stretches to Slovakia, where the occurrence of root vole was recorded in the Danube Lowland, near Szigetköz as well as in a number of other wetland sites in the lowland. Isolated population was found in Parížske močiare marshes in the Hronská pahorkatina highlands, which represents the farthest eastern location of the root vole occurrence so far known.
The main part of the Root vole fodder consists of sedge (Carex), reed (Phragmites), bulrush (Typha) and grass (eg. Molinia). The mating season lasts from May to September, the number of litters is 1-3 per year and the number of youngsters is from 5 to 11. The spatial activity of the root vole is not great, it is restricted by the habitat characteristics and its size.
Females have their first litter in the spring still in their wintering habitats. Through late spring voles search wetter summer habitats and in late summer they find dryer habitat for wintering. These seasonal migrations might be influenced by local habitat conditions. The connection of populations by bio-corridors is one of important factors to avoid the populations isolation.
