S<strong>in</strong>ce Lake Monastir is managed for fieh production, there are several<br />

water control structures <strong>and</strong> fksh traps. Guardians keep out other sources<br />

of distarbance, so the site is a safe haven for many birds.<br />

3.3.1.5. Monastir Salt Ponds (sal<strong>in</strong>es)<br />

West of Monastir is the lagoon that replaced Lake Monastir as a salt<br />

collixtion site. The site is over 1000 ha, much of which has been<br />

sectiored off <strong>in</strong>t~ evaporation ponds. The sal<strong>in</strong>es are further <strong>in</strong>l<strong>and</strong> than<br />

Lake Mocastir <strong>and</strong> the banks prevent free circulation of the water.<br />

A. Vegetatioc<br />

Halocnemum strobilaceum, Arthrocnemum <strong>in</strong>dicum, Salicornia sp. <strong>and</strong><br />

Halopeplis amplexicaulis dom<strong>in</strong>ate the vegetatkon on the shores of the<br />

salices. Poor water circulation <strong>and</strong> high sal<strong>in</strong>ity prevent vegetation<br />

growth ic maay of the sections. In the large, less- salty sections green<br />

filarneetom algae mats form.<br />

B. Fauca<br />

Mammals. Brown hares <strong>in</strong>habit the halophile vegetation around the salt<br />

pocds acd it is possible that red fox <strong>and</strong> Egyptian mongoose occasionally<br />

occar there. The range of Shaw's jird <strong>and</strong> Gerbiillus campestris (gerbil)<br />

extecds to this area <strong>and</strong> the habitat between the saltponds <strong>and</strong> the<br />

Mocastir airport is favorable for those species.<br />

-<br />

Birds. Many species of waterfowl <strong>and</strong> waders feed <strong>in</strong> the salt ponds<br />

sad there are several nest<strong>in</strong>g species such as shelduck <strong>and</strong> little tern.<br />

Most of the species found along the coast of the Gulf of Hammamet <strong>and</strong> the<br />

Calf of Gabes probably also stop at the Monastir salt ponds <strong>and</strong> Lake<br />

Mocastir. Species present <strong>in</strong> August, 1987 <strong>in</strong>cluded:<br />

Little grebs<br />

Grey heron<br />

Little egret<br />

Flam<strong>in</strong>go ( 1 400 )<br />

Spoonbi 11<br />

Herr<strong>in</strong>g gull<br />

Little tern<br />

Collared prat<strong>in</strong>cole<br />

Spectacled warbler<br />

Lesser short-toed lark<br />

Water level manipulation <strong>and</strong> equipment operation for salt production<br />

affect the vegetatioc <strong>and</strong> nest<strong>in</strong>g birds. The adjacent airport causes some<br />

distxbacce to the birds. Water quality is fairly good si~ce it must be<br />

kept clear for acceptable salt prodaction. Fish are seiced ic the larger<br />

pocds, bat l-r~cticg is usaally not allowed.
