Compensation measures

In order to reduce loss of biodiversity, especially with regard to birdlife, a very important area of REN's activity involves compensatory measures following the environmental impact assessment of new infrastructures.

1. Number of trees felled (construction of new RNT and RNTGN infrastructures)

After having compiled the information available on the different construction projects, below is a calculation of the number of trees felled, per construction for REN Eléctrica, REN Gasodutos and REN Armazenagem. This calculation takes into account not only the number of trees felled but also the area covered. In the latter case the figure is based on an average density estimate (trees/ha) for each region.

In 2016, a total of 107,353 trees were planted in an area of approximately 395 hectares. The following species are of note:

•Oak: 54,131 planted

•Cork oak: 3,618 planted

•Chestnut/Walnut: 15,049 planted

•Olive trees 5,143 planted

•Strawberry trees: 1,032 planted

•Stone pines: 28,380 planted

 

In 2016, approximately 286 000 trees were felled in REN construction work, representing a forest area of around 193 hectares.

In 2016, the major projects were:

•Vieira do Minho-Pedralva line 2: 27%

•Pedralva-Ponte de Lima line: 19%

•Terras Altas Fafe-Riba D'Ave line, opening to Fafe: 14%

Douro Internacional and Távora Valley

The implementation of compensatory measures is aimed at the ecological restoration of populations of rock-dwelling birds (black stork, Egyptian vulture, Bonelli's eagle, golden eagle, eagle owl, peregrine falcon and red-billed chough) in the Douro Internacional Natural Park and River Távora Valley, as follows:
- habitat management for wild rabbit and red-legged partridge;
- construction and population of traditional dovecotes;
- installation of ponds;
- promotion of extensive grazing.
In addition, a monitoring plan will be implemented for these species.

Macedo de Cavaleiros – Valpaços Line

The compensatory measures that have been implemented in the River Tuela Valley since the first three months of 2012 are aimed at the black stork and include:
- reducing anthropogenic disturbances;
- protecting nesting cliffs against fire;
- restoring weirs.
Specific monitoring of the black stork is also being carried out.

Armamar-Recarei Line

The compensatory measures that are being implemented, from 2013, in the Trás-os-Montes e Alto Douro are directed to Eagle of Bonelli and consist of the implementation of management measures of habitat for prey species rabbit and Red-legged Partridge. It is also held specific monitoring of Bonelli's Eagle.
