Every record counts. Whether you are an experienced naturalist or simply walking along the river with your phone, you can help us track the spread of invasive alien species in protected areas along the Danube. All you need is the iNaturalist app and a curiosity for the natural world.

What is iNaturalist?

iNaturalist is a free citizen science platform used by millions of people around the world. Using the app, you photograph an organism in the field, the platform helps identify the species, and your observation becomes part of a scientific database. Simple, fast, from anywhere.

Why do we monitor invasive species?

Invasive alien species are among the leading causes of biodiversity loss in Europe. They spread rapidly, displace native plants and animals, and fundamentally alter entire habitats. The sooner a new occurrence is recorded, the sooner we can respond. This is exactly why public monitoring is so valuable: you are our eyes in the field.
Within the LIFE Resistance project, we monitor 16 selected invasive species across Natura 2000 sites along the Slovak-Hungarian border section of the Danube. Every recorded observation helps us better understand where and how quickly these species are spreading, and enables us to plan their removal.

Resistance: Danube Alien Species

Once you are a member of the project, your observations of the target invasive species from the Danube area will be automatically linked to our monitoring data.

Step 4: Photograph and upload your observation

In the field, simply:

1. Open the app and tap Add observation

2. Photograph the plant (ideally from multiple angles)
3. Record the location and date (the app does this automatically if your GPS is enabled)

4. Confirm or add to the species suggestion the app provides
5. Submit the observation

If you are unsure of the species, do not worry. Upload it anyway. The iNaturalist community of experts and its AI identification system will help.

Tips for good quality records

• Always photograph the whole plant as well as close-up details of leaves, flowers or fruit.
• For trees and shrubs, a shot of the bark and any new shoots is also useful.
• Do not forget to enable GPS location; it is the most important piece of information for us.
• If you are unsure of the species, add a note or tag the observation with the project name.
• The best time to photograph plants is during flowering or fruiting, when identification features are most visible.

Which species are we looking for?

We focus on 16 invasive alien plant species occurring in the Danubian floodplain area. You can find the full list with photographs and identification guides, as well as map of the monitoring area directly in our project on iNaturalist. If you manage to record any of them in the Slovak-Hungarian border area along the Danube, it is an exceptionally valuable find for us.

In April 2026, part of our team travelled to the Netherlands for a three-day study trip, visiting partners, experts and projects that left us with a set of fresh ideas and inspiration to carry into our future work.

Breda

Our first stop was Breda University of Applied Sciences, where we introduced students to BROZ, shared some of our projects, and devoted most of the session to the topic of aquatic restoration as it is one of the key activities we are planning to implement within the LIFE Resistance project. It is always a pleasure to share our work with the next generation of people who will shape the future of nature conservation.

Nijmegen

In Nijmegen, we started the morning with a visit to RAVON, an organisation with long-standing expertise in eDNA monitoring. This relatively new but remarkably powerful method is one we also use to track fauna on restored sites within our project, whether following the reintroduction of grazing or the revitalisation of wetlands. The discussion with RAVON’s eDNA specialist offered valuable insight into different approaches.

The evening was spent with the team behind the LIFE Resilias project, which focuses on the elimination of invasive plant species. One species we have in common is Fallopia sp., and the exchange was particularly stimulating. Rather than relying on chemical methods, the Resilias team plants native species that gradually outcompete the invasive growth. On some sites, this approach has already proven successful, which is excellent news for the field as a whole.

Border Meuse

The final day was dedicated to a full-day field excursion with experts from ARK Rewilding Nederland along the Belgian-Dutch border. We had the opportunity to witness large-scale river restoration on the Meuse, where nature-based flood management measures are interwoven with the return of semi-wild grazing. The animals live in near-wild conditions, and their grazing naturally shapes the landscape around them.

We are grateful to all our hosts for their time, openness and willingness to share their experience.

Just across our border lies the unique region of Hortobágy, inscribed on the UNESCO World Heritage List. In April, we travelled there together with farmers and mayors from southern western and eastern Slovakia, to see firsthand what a successful integration of agriculture and nature conservation looks like in this iconic steppe landscape.

What did we learn and what inspired us?

• A world of traditional organic farming: At the Virágoskút ecofarm, we saw how almost the entire production process can be brought together under one roof, from livestock rearing and vegetable growing to processing and selling products, all in harmony with nature and with deep respect for tradition. Places like this tend to attract not only customers, but curious visitors too.
• The value of extensive grazing: At a local farmer’s property, we discussed how extensive grazing with native breeds contributes to restoring a healthy landscape while also supporting the development of the wider region.
• The heritage of traditional livestock keeping: A visit to a stud farm and demonstrations of native livestock breeds showed us just how important it is to preserve genetic and cultural heritage as a resource of incalculable value.
• Wildlife up close: A highlight was the visit to Vadaspark, where we had the chance to see representatives of the region’s original wild fauna. A particularly memorable moment was a guided wolf feeding session, a vivid reminder of the place that wilderness still holds in today’s landscape. 
• Culture and the celebration of tradition: The shepherd museum brought local traditions to life in a contemporary way, something this region takes great pride in, while the newly updated visitor centre offered a fresh and engaging look at the birds and flora of the local puszta.

We left with a strong conviction that this integration of farming traditions and nature conservation is exactly the path we want to follow in restoring our own lowlands. Thank you to everyone who joined us for the inspiring company and stimulating discussions!

We also thank our friends from the organisation Zöld kör for guiding us. This event was carried out within the framework of the project LIFE21-NAT-SK-LIFE 4 STEPPE BIRDS “Protection and Return of Steppe Bird Species to the Lowlands of Slovakia”. The project is co-financed by the European Union.

This spring, one of the most encouraging signs of success has appeared on sites we have been restoring within the LIFE Sub-pannonic project – pasque flowers have started to bloom.

These iconic species of dry grasslands are among the first to respond to improved habitat conditions. Their return clearly shows that the restoration measures we implement – especially the removal of encroaching shrubs and trees, reintroduction of grazing, and regular mowing – are helping these habitats recover. The abandonment of traditional land use was one of the main reasons for their decline in the past.

The LIFE Sub-pannonic project focuses on the restoration of valuable dry grassland habitats across dozens of sites in Slovakia and Moravia. These habitats are exceptionally rich in species, but also highly sensitive to changes in management – without regular care, they quickly become overgrown and lose their biodiversity.

The blooming pasque flowers are therefore more than just a beautiful sight. They are a symbol of ecological recovery and a reminder that even long-neglected landscapes can return to life when given the right care.

We would like to thank all partners, land managers, and volunteers involved in the restoration efforts. Thanks to this cooperation, species that have been disappearing from our landscape are slowly returning.

In the open landscape of Slovakia’s lowlands, where the LIFE Steppe Birds project operates, rows of ancient pollarded willows are truly irreplaceable. To us they are a beautiful part of the scenery, but for the European roller and the red-footed falcon, they are strategic sites for life itself. To ensure these trees continue to serve their purpose in 2026 and beyond, we need to give them their characteristic “crown”.

Why is pollarding essential to the project’s goals?

Our project focuses on protecting species associated with open steppe landscapes. Although willows often grow along canals and ponds with muddy banks, their importance for steppe birds is immense:

• Nesting cavities: Regular pollarding following BROZ’s expert guidelines stimulates the tree to develop natural cavities. These are far more attractive and safer for the European roller than artificial nest boxes.
• Landscape stability: Without pollarding, old willows would eventually split under the weight of their branches, and entire nesting lines would be lost. Regular “willow cutting” extends the life of these trees by decades.
• Food supply: Freshly pollarded willows and the piles of cut branches left nearby provide habitat for hundreds of insect species, which are the primary food source for the chicks of our target bird species.

How we work (in line with the guidelines)

Within the activities of the LIFE21-NAT-SK-LIFE 4 STEPPE BIRDS project, we follow proper techniques that respect both the biology of the tree and the needs of the birds:

1. Winter timing: All pollarding is carried out exclusively during the vegetation dormancy period (January to February), so that the habitat is ready before the spring arrival of falcons and rollers.
2. Cutting to the crown: Branches are removed with a chainsaw close to the trunk, encouraging the characteristic shape that gives birds an excellent vantage point over their hunting grounds.
3. Supporting shrub cover: Around water bodies, we retain denser shrub vegetation, which provides shelter for small wildlife and increases the overall biodiversity of the site.

Last week we celebrated World Wetlands Day! On February 2, we celebrate the crucial role wetlands play for both our planet and its people. These incredible ecosystems are among the most productive on Earth, offering essential services like water regulation, flood protection, carbon storage, and support for biodiversity. They also provide livelihoods for millions.

Our partners from the Plant Science and Biodiversity Center study wetlands from many different perspectives—from the bottom of the waterbody, through dense riparian vegetation, to the hidden diversity of wetland sounds. Using in situ data collection, eDNA analysis, vegetation research, bioacoustics, and remote sensing techniques, we aim to deepen our understanding of wetlands. The results of this research provide a valuable foundation for wetland restoration, which they are actively involved in through the LIFE Resistance project.

Let’s raise awareness and protect these vital habitats!

A key part of our LIFE Endemic PANALP project, focused on restoring thermophilous and xerothermic grassland habitats, is cooperation with local farmers. Thanks mainly to this collaboration, we have so far managed to reintroduce or expand grazing on more than 240 hectares across 28 sites, stretching from Devín to Súľov. Our goal, of course, is for these restored areas to provide long-term benefits to the farmers, which will undoubtedly also bring significant gains for nature.

Agricultural subsidies are today an important tool in this regard. Therefore, on Monday, November 3, we organized a seminar for our cooperating farmers with our colleague who had worked for several years at the Agricultural Paying Agency. In an informal and friendly atmosphere, he explained to beginning farmers the basics of the Common Agricultural Policy rules, while the more experienced participants had the opportunity to discuss their experiences and challenges.

The venue – the Pub in Višňové – was chosen deliberately. We would like to start restoring goat grazing on the overgrown steppes directly below Čachtice Castle together with the locals here in the near future!

Coincidentally, we continued our education activities aimed at the same target group the very next day. At the Uhliská Farm near Nemšová, in cooperation with the Institute of Knowledge-based Agriculture and Innovation, we co-organized a seminar focused on grassland restoration, environmentally friendly deworming of livestock, and smart technologies in animal husbandry.

Our colleague Jakub Cíbik presented to the participants that restoring flowering meadows is an opportunity not only for biodiversity but also for building cooperation between conservationists and farmers. His lecture also included inspiring examples of such partnerships that have emerged thanks to the LIFE Endemic PANALP project.

Ivana Kodajová from the Vlčí Vrch goat farm, with whom we have been closely collaborating since the earlier LIFE Butterflies project, introduced her well-developed system of gentle goat deworming. Conventional methods, which rely on the widespread use of ivermectin-based substances, lead to parasite resistance and simultaneously kill coprophagous insects. These organisms, which decompose animal dung, are an important part of biodiversity and help farmers improve soil condition, fertility, and even reduce the occurrence of undesirable parasites.

For these reasons, at BROZ we have decided to promote awareness of practices that are more considerate of both livestock and the grassland ecosystems — ecosystems that, in our country, survive today largely thanks to them.

After more than a year of effort and work, the technical documentation for the revitalization project in Klížska Nemá is complete. In cooperation with designers from SVP and experts from the Water Research Institute (VÚVH), we have managed to design a series of measures that will help create “wild” islands on the main channel of the Danube in Klížska Nemá.
This will be the first revitalization of its kind in Slovakia, where we will lower and disconnect the groynes – guide embankments that direct water into the navigation channel (“výhony”) from the riverbank. This will create a parallel river branch within the main channel and provide a refuge for Danube fish species.

Our plans are ambitious and gradual — in the future, we would like to modify the entire groyne system in Klížska Nemá, consisting of a total of eight groynes, implemented in three construction phases.

We have now entered the permitting process and held numerous meetings with the relevant stakeholders, including the Slovak-Hungarian Commission for Boundary Waters and the Ministry of Transport — all with positive outcomes. So let’s get started!

These activities are being carried out as part of the #LIFEWILDisland project.
