logical changes lead<strong>in</strong>g to erosion or flood<strong>in</strong>g of<br />

colonies, and hous<strong>in</strong>g development [13, 21] . For example,<br />

eutrophication drove decl<strong>in</strong>es <strong>in</strong> Dalmatian<br />

pelicans <strong>in</strong> Albania until 2007 [13] . The next most<br />

important threat is disturbance by human activities<br />

and illegal persecution [13, 21] .<br />

Collision with and electrocution by power<br />

l<strong>in</strong>es is also an ongo<strong>in</strong>g threat, particularly dur<strong>in</strong>g<br />

migration and the non-breed<strong>in</strong>g season [13, 21] .There<br />

is an <strong>in</strong>creas<strong>in</strong>g number of w<strong>in</strong>dfarms be<strong>in</strong>g<br />

developed along the ma<strong>in</strong> flyways used by<br />

Dalmatian pelicans and near key wetlands, and<br />

collision with w<strong>in</strong>d turb<strong>in</strong>es could potentially have<br />

a high impact on the species [13, 21] .<br />

Drivers of recovery<br />

Dalmatian pelican recovery <strong>in</strong> Europe is largely the<br />

result of targeted conservation efforts, especially<br />

limit<strong>in</strong>g disturbance by people [13, 22] . However,<br />

overall capacity to carry out management and<br />

enforce protection of colonies is considered to be<br />

low and improvements are necessary [13] . In Greece,<br />

where the European Species Action Plan (SAP) for<br />

Dalmatian pelican has been implemented most<br />

successfully, the breed<strong>in</strong>g population of the species<br />
