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 />

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 />

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.
