Threats to Biodiversity

Despite its ecological wealth, Portugal faces challenges including habitat loss, pollution, invasive species, and climate change, all of which threaten its biodiversity.

Interactions Between Wind Farms and Biodiversity

Potential Ecological Impacts of Wind Energy Development

While wind energy is a clean and sustainable source, its development can pose risks to local ecosystems. Key impacts include:

1. Avian Mortality:

• Collisions with turbine blades are a primary concern, especially for raptors, migratory birds, and large soaring species.
• Species such as the Black Vulture and European Imperial Eagle are particularly vulnerable due to their flight patterns.

2. Bat Mortality:

• Several studies indicate that bats are susceptible to turbine-related injuries, with some species facing population declines.

3. Habitat Disruption:

• Construction and operation can fragment habitats, disturb breeding or foraging grounds, and alter landscape connectivity.

4. Noise and Visual Disturbance:

• Turbine operation generates noise and movement that can disturb sensitive species.

5. Indirect Effects:

• Changes in predator-prey dynamics and plant pollination processes due to habitat alterations.

Empirical Evidence from Portugal

Research conducted in Portuguese wind farm regions has documented:

• Variable collision rates influenced by species behavior, turbine placement, and migratory routes.
