Despite their distinct value, dunal ecosystems share a long history of exploitation and inappropriate management.
The problems associated with coastal use include:
- Loss of habitats
- Loss of the natural landscape pattern
- Spread of alien species
- Growing threats to native species
- Loss of resiliency by plant communities
Tourism is currently considered one of the major causes of this deterioration. Although it constitutes an important economic stimulus, both in terms of revenue and employment, it poses a threat to dunal ecosystems.
An intense anthropic pressure, associated with a general lack of ecological awareness can therefore compromise the naturalistic value and ecological functionality, but also the distinctive elements of the landscape that constitute one of the attraction factors for tourist flows.
