ENVIRONMENTAL IMPACT AND CLIMATE ACTION (E)Compensation measures in connection with the construction of a line or substation

At the stage of network infrastructure execution and operation, a negative impact on the habitats of fauna and flora can be observed, which may result in a decrease in biodiversity. In order to reduce this negative impact, the implementation of a project is preceded by a planning and analysis phase, which allows limiting its impact on protected and other species. Where required by applicable provision of law, environmental decisions confirming that the works and operation of the projects will be carried out in a way that minimises the impact on the environment are obtained. Where it is not possible to avoid environmental impacts, efforts are made to reduce them. In a situation where this does not have a measurable effect, environmental compensation measures are implemented after obtaining decisions allowing derogations from prohibitions, the so-called derogation decisions. On the basis of derogation decisions, protected species are trapped, relocated or destroyed during project implementation, and their habitats are subject to restoration. Compensation measures are aimed at restoring the environmental balance of the area and compensating for the damage done to the environment.

Construction of Jasiniec–Grudziądz Węgrowo line – as part of environmental compensation for the disturbance of 91E0 willow riparian forests and 9170 oak-hornbeam forests natural habitats, by virtue of the environmental decision obtained, nesting boxes and roosts were provided in Toruń and Żołędowo Forest Districts in 2019 for:

  • the common redstart, the European pied flycatcher, the Eurasian nuthatch, the Eurasian tree sparrow, the great tit, the willow tit, the coal tit – a total of 29 A- and A1-type boxes,
  • the starling – 6 B-type boxes,
  • the black redstart – 10 semi-open-type boxes,
  • the short-toed treecreeper and the Eurasian treecreeper – 4 boxes,
  • the common goldeneye – 1 box near the Vistula River on the height of pole No. 32, 1 box at the Papowskie Lake near pole No. 113,
  • bats – Issel-type boxes (intended for, among others, the common long-eared bat, the grey long-eared bat, the lesser noctule, the mouse-eared bat, the common noctule, the Nathusius' pipistrelle) – 20 roosts,
  • bats – Stratmann-type boxes (intended for, among others, the common pipistrelle, the soprano pipistrelle, the brown long-eared bat, the common noctule and the Nathusius' pipistrelle) – 20 roosts. In 2021, our naturalist carried out the cleaning and maintenance of nesting boxes and bat roosts as part of the annual box inspection. During the work, traces of nesting in the form of nest material or abandoned egg shells were found in most nesting boxes. No individuals were found in the bat roosts, as they are not breeding or permanent sites for bats – they are only periodic hideouts.

In September 2021, 2 nesting platforms for the white-tailed eagle (Haliaeetus albicilla) were provided in the area of Żołędowo Forest District as part of environmental compensation measures. The locations proposed by the Forest Inspectorate were approved by the Regional Director for Environmental Protection in Bydgoszcz. The work was carried out under the supervision of an ornithologist. The platforms were located in the stand of an approximately 114-year-old Scots pine and in a clump of old-growth forest, which includes an oak aged approximately 129 years.

Construction of Bydgoszcz Zachód – Piła Krzewina line – protection of the early marsh-orchid (Dactylorhiza incarnata) species present within habitat 6510 – lowland and mountain fresh meadows used extensively.

During the construction of Bydgoszcz Zachód–Piła Krzewina electrical power line, the early marsh-orchid (Dactylorhiza incarnata) species present in the vicinity of pole 185 was replanted on the basis of the environmental decision obtained. The replanting was carried out in 2019, under the supervision of a naturalist, in the area of the same habitat 6510 ─ lowland and mountain fresh meadows used extensively. In 2021, a botanist assessed the condition of the replanted orchid specimen and the abundance status of specimens of this species as part of environmental monitoring. During the monitoring, two specimens of the early marsh-orchid belonging to the family Orchidaceae were found, which developed generative shoots in 2021.

Conservation of the common osprey

PSE, together with the State Forests, implemented measures to protect the osprey (Pandion haliaetus). In total, 9 special platforms were installed where birds can build their nests. Two platforms were inhabited by 2 osprey couples out of 22 recorded in Poland.

This project contributes to increasing the breeding area of the osprey (Pandion haliaetus), which should have a direct impact on increasing the population of this species.

Ospreys (Pandion haliaetus) are one of the rarest birds of prey in Poland and are under strict protection. According to the statistics kept by the Eagle Protection Committee, our country is currently inhabited by only 22 couples of these animals, and some of them inhabit areas near power infrastructure.

The installation of osprey platforms on power poles is a good and proven practice in addition to the installation of platforms on trees. It is used, among others, in Germany, where about one third of the osprey population nests on high voltage poles. Protecting nests in this way increases the chance of birds settling in.

The construction of nesting platforms for ospreys is a continuation of measures commenced by PSE in 2014. Installation of another 3 nesting platforms was carried out in 2021 on supporting structures (poles) of EHV lines: Krajnik-Glinki, Morzyczyn-Police and Krajnik-Vierraden. Since the start of the project, 9 platforms have been successfully installed on power poles.
