Planned actions	Ecological benefit
Reduce the number of wind turbines from 46 to 34 across the project area	Total reduction of the project’s impact on the natural environment
	Enlargement of the biologically active surface

	Enlargement of the area of habitats available to birds
	Enlargement of the area of habitats safe for white-
	tailed eagles and facilitate collision-free access to
	feeding ground
	Enlargement of areas free of risk of
	collision with wind turbines,
	Elimination of a row of wind turbines along the Tywa
	River Valley, reduction of the barrier effect
