Mavrovo National Park

The National Park

Dam construction plans put national park at risk



The Mavrovo National Park in Macedonia is one of Europe’s oldest national parks. It is famous for its extensive beech forests, alpine meadows, pristine rivers and streams. A huge variety of species, such as rare trout species, wolves, bears, and otters, live in the park. One species is outstanding though: the Balkan Lynx (Lynx lynx balcanicus). The Mavrovo National Park is the centre of the remaining population of this critically endangered subspecies of the Eurasian Lynx.

The park hosts more than 1,000 different plant species. It is part of the southernmost section of the European Green Belt - an outstanding ecological network that has developed undisturbed along the former iron curtain.

The Threats

The Threats

The Mavrovo National Park has first been compromised in the 50s, when a medium scale hydro-power project (HPP Vrben) was build inside the park’s boundaries. Adding to HPP Vrben, two more large scale hydro-power projects (HPPs) – “HPP Boskov Most” and “HPP Lukovo Pole” – as well as 20 smaller ones are now planned inside Mavrovo NP. If these 22 projects – or only some of it - will be implemented as foreseen, severe negative impacts on the biodiversity of Mavrovo National Park will be the consequence, undermining the very idea of a national park. Moreover, these projects risk the revocation of the national park status.

Of the 22 projects, two have already been completed and are in operation. Another one is under construction, while the remaining 19 projects (Boskov Most, Lukovo Pole and 17 small ones) are to be built in the next few years. Every single one of these projects destroys one creek inside the national park; the overall impact of all projects and their necessary infrastructure will have even more profound consequences. Hardly any creek inside the national park would flow freely any longer. This is particularly the case since, according to Macedonian law, no environmental impact assessment is required prior to the issuing of water licenses for HPPs up to a capacity of 5 MW.

A total of 22 HPPs are to be built inside Mavrovo NP. Two are arleady completed, one is under construction, while 19 are in the planning phase.

Hydropower Plant "Boskov Most"

The dam project Boskov Most is located in the upper Mala Reka valley in the southernmost part of the national park. The main source of funding for this dam project is the EBRD – the European Bank for Reconstruction and Development. The HPP is designed to produce peak energy. For that purpose the discharge of Mala River as well as its two major tributaries and several smaller streams in the area will be diverted into a reservoir via pipes and canals. On demand, the water will be released once a day. This will mean daily flushes, which have enormous negative impacts on biodiversity and species populations in the river sections below the power-house – and all this in a national park. Furthermore, riverine ecology of the entire valley will severely suffer from the diversion of the majority of its natural water supplies.

Facts and Figures

  • Dam hight: 33 m
  • Output: 68 MW
  • Max daily flush: 22 m³/s in 5h per day (average discharge of Mala Reka: 5.75 m³/s)
  • Construction/widening of new roads: 16.4 km
  • New supply channels: 19.70 km
  • Directly affected area inside Mavrovo NP: 935 ha
  • Investment: 84 Mio EUR, 65 Mio. EUR provided by a EBRD loan

The final evaluation of HPP Boskov Most’s compliance with the funding criteria of the EBRD is not yet finished

In contrast to the official conclusion of the “Biodiversity Survey” commissioned by the leadership of the Macedonian Energy Group ELEM, the HPP Boskov Most would result in severe destruction of biodiversity and in population decline of endangered species. Internationally renowned experts analysed the biodiversity survey and came to the following conclusions:

Bajohr“The proposed drainage of the streams, detailed in this report, will have an immediate negative impact on the fish habitats and fish populations in these watersheds. In our opinion this biological diversity survey remains superficial, incomplete and misleading with regards to the otter, clearly not taking the risks to this threatened species seriously.”

Dr. Nicole Duplaix, Chair of the IUCN‐SSC Otter Special Group


“The proposed actions in the National Park will have strong negative effects on the native trout populations which will largely vanish from the reservoir area as well as from the downstream sections of the dam...”

“Overall, there seems to be the view that …, the negative effects can be easily mitigated.  This is not a view that I can… share, and …I strongly feel that it is in stark conflict with the primarily management goals of an IUCN Category II National Park.”

Dr. Steven Weiss IUCN Salmonid Specialist Group (SSG) & Red List Authority (RLA) forSalmonid Fishes in Eurasia


“Mavrovo hosts [...] the last source of population with reproduction of the Balkan lynx [...]. Putting any additional stress on this source population may lead to the extinction of one of the most threatened mammal populations in Europe.”

Dr. Urs Breitenmoser, Co-Chair, IUCN-SSC Cat Specialist Group

This project is planned to be constructed close to the Macedonian border with Kosovo. The main source of funding is the World Bank. The Lukovo Pole project shows many similarities with Boskov Most. The water will be diverted from several tributaries to the Radika River, which will be channelled to the reservoir through a pipe system.

Initially, the Dlaboka Reka valley, characterized by unique ancient beech forests would have been among the affected areas. Just recently it was identified as a potential World Heritage site by an international expert delegation and excluded from construction plans by the financiers – a first success. Yet, the reservoir is to be constructed in one of the richest and most beautiful parts of the national park in terms of plant biodiversity, representing a niche for the specialists amongst Europe´s plant species. According to PlantLife, the Lukovo Pole project would affect 17 threatened plant species, like the endemic fritillary Fritillaria macedonica and Narthecium scardicum. Furthermore, the site hosts 13 threatened habitats, such as alpine and boreal heaths (listed in Annex 1 of the EU Habitats Directive)  and Balkano-Pontic fir forests characterized by high endemism.

Facts and Figures

  • Dam hight: 71 m
  • Output: 6 MW,  estimated at 159 GWh per year with respect to additional benefits from existing HPPs
  • Max daily flush: 6 m³/s
  • Construction/ widening of roads: > 20 km road widening and bituminisation
  • New supply channels: 19.95 km
  • Directly affected area inside Mavrovo NP: 3,546 ha
  • Investment: 83 Mio EUR, 70 Mio EUR provided by a World Bank loan; the World Bank has not yet confirmed supplying the funds to start the construction of the project.

  • A total of over 4,400 ha of natural habitats would be directly affected by the two dam projects "Boskov Most" and "Lukovo Pole" alone.
  • All dam projects are violating national park guidelines
  • In other words, the EBRD, the World Bank as well as other investors involved in the implementation of the 16 smaller HPPs are planning to fund the possible revocation of  Mavrovo’s status as a national park!


We demand

  • No new hydropower plants inside the national park!
  • The EBRD, the World Bank as well as other investors of the smaller HPPs must retract their funding of these projects!
  • The government of Macedonia must stop and abandon the projects!
