In October 2015 the construction of the embankment between Lake Kűvölgy #3 and #4 has begun.

The works started by cutting of the trees hindering the activities of the action, stripping the topsoil of the enbankement, demolishing the old spillway and outlet tower.


The contractor placed the ready-made concrete items of the new spillway to the base structure, refilled and heightened the embankment as per set in the technical plans.


In connection with the advancement of the tender, a press conference – which was interlaced with a public information meeting – has been held on 27th October 2015.

First of all, István Lábodi has described the LIFE project.
Secondly, Mihály Szász drawn the public’s attention to the foregoing results.
Lastly, László Nagy and András Koltay have represented the monitoring duties, as well as the experiences of the measuring.

After the conference, there was an opportunity to view the foregoing implemented works.

Notable occurrences of Quaking Grass Sedge (Carex brizoides) have been found during the botanical survey of the project area. Several stands grow under low canopy closure and/or near glades and forest roads. Witnessing the favourable habitat structure and the presence of the larval food plant led us to systematically survey these plots for Woodland Brown. 5 specimens of the butterfly have been found in two locations near the edges of the project area in 16.06. 9 specimens were observed during the repeated survey in 22.06.

The butterfly has been mentioned in the Natura 2000 documentation of the area. However, local occurrence has not been confirmed yet by published reference or collected and archived specimen, so we consider this data as novel information.


Woodland Brown (Lopinga achine, Scopoli 1763.)

Single-brooded species, the adult flight period is from mid-May to early July. The butterflies do not visit flowers, but feed on damp soil surfaces, dung and carrions. The eggs are laid on the blades of grasses growing in dappled sunlight. The larvae hatch in mid-July, feed on grasses and sedges, primarily on C. brizoides for a few weeks, then hibernate. They resume feeding early in spring, and become fully grown by mid-May.

The Woodland Brown is fond of warm, open places in damp, deciduous or mixed woods with well-developed shrub and herbaceous layers. It is a sporadic Eurasian species with rare and local occurrences. Stable, but small and isolated Hungarian populations are known in Aggtelek and Őrség.

Due to the population decline witnessed throughout the European populations, this species is considered as vulnerable. Woodland Brown is listed on the Habitats Directive Annex 4 and Bern Convention Annex 2, and is protected in Hungary.



The II. phase of the public procurement, obliterated in connection with the selection of the contractor of the workmanship has been terminated on 2nd October 2015.

The task was won by the Sziget-Melor Mélyépítő és Szolgáltató Kft.

The contract was signed on 14th October 2015.

The exploited sludge will be used up to the reparation of the woody roads.

The works have started after the drying of the sludge.
