Abstract |
The encroachment of scrub in the dunes has strongly effected the breeding bird populations. The number of typically scrub-dependent breeding birds like White- throat and Nightingale has increased dramatically during the last decades. These species were already relatively common in the fifties. In the same period though, more demanding species like Montagu's Harrier, Wryneck, Nightjar and Red-backed Shrike have {almost} become extinct in the dunes. This indicates that, although the area of scrub increased, the habitat quality has declined. Also other species of pioneer vegetation like Skylark and Wheatear have shown a sharp decline in the number of breeding pairs. In order to detect the true causes of decline and to take the right restoration measures, thorough monitoring of the food chain and habitat requirements of species like Montagu's Harrier and Red-backed Shrike are required. Next to monitoring numbers, also information should be collected on breeding success and survival in order to understand the full impact of habitat changes and nature management. |
