INTRODUCTION
e total coastline of Libya is about 1975 km long, numer-
ous salt marshes bordered by sabkhas occur along the coast,
these sabkhas cover some a very large area on the coast line
and most of them are completely dry during the summer
season. e sabkha has been identied as a natural bio-
tope for special poor vegetation cover composed mainly of
halophytes and desert plant taxa around the sabkha due to
coarse sand texture and prevailing semiarid conditions [1].
Salt pans (sabkhas) and salt-marshes occur along the coast-
al strip, formed by the ponding and subsequent evapora-
tion of water behind the coastal dunes. ese arise where
run-o collects, but the capillary rise of groundwater from
a shallow water table has also contributed to the develop-
ment of these features. One of the largest sabkhas is located
in the western part of Libya and is called “the Abu Kam-
mash salt marsh (Abu Kammash subkha)” and it is found
along the coastal Libyan-Tunisian highway about 150 km
west of Tripoli in the Abu Kammash area near the Tunisian
border, carry salt-marsh vegetation. In addition, there are
saline marshes on the Plain of Gefara inland. To the east of
Tripoli there are some water bodies so formed may persist
from year to year. e most important of these are in the
Wadi Kaam between Al Khums and Zlitan, and in the Wadi
Turhat some 50 km east of Tripoli, these water bodies are
brackish and fringed by reeds, rushes and sedges. To the
east of Mistratah is the great sabkhat of Tawurgha which
extends along shore behind the sand beach for 100 km
between Misratah and Bu’ayrat al Hasun. Other salt pans,
some of considerable extent, occur inland on the Plain of
Sirt. the Sabkhat al Qunayyin, and the great marsh behind
the coastal dunes at Ajdabiya, this is 70 km long and 12 km
wide in places, and carries typical salt-marsh vegetation.
North of this, continuing up the eastern side of the Gulf of
Sirt towards Banghazi, there is a series of salt pans subject
to temporary inundation behind the barrier beach. Immedi-
ately north of Qaminis, a system of pans reaches 40 km in-
land from the sea carry halophytic vegetation. Others north
of Banghazi have fresh water pools, but these particular sites
are very much disturbed and threatened by the encroach-
ment of urban development. To the south of the country
also there are several oases and wetlands such as oases of
the Ghat region, oases of Sebha district, the lakes of Wau En
Namus, the oases of Kufrah and others. All these wetlands
with special halophytic and desert vegetation [1].
In Libya there are no adequate oristic studies on such sa-
line habitats, except the study of Kikili & Erteb [2] on the
ora of Farwa island, so one of the important coastal salt
marches is Mallaha wetland in the North east of Tripoli,
the diversity of Mallaha which is mainly characterized as a
salt-marsh habitat suitable for halophytic and salt tolerant
plants, it is still oristically unexplored and this work is the
rst oristic and inventory study in this wetland, so it may
provide new contribution to the biodiversity status of such
habitats.
Study Area
Mallaha is a wetland located in northeastern Tripoli (32°
53’ 58” N, 13° 17’ 15” E) (Fig 1). e site is about 2.5 km
in length with a maximum width of about 1.5 km. It has a
surface area of about 3.75 ha. It is a salt marsh, fed by a canal
from the sea year round and by rainfall during winter. e
northern part of Mallaha is dominated by dry sandy areas,
grasses, dry and wet streams, canals, and brackish and salty
pools. It also contains trees and shrubs, dumping yards for
garbage and waste materials, the ruins of old residential and
military buildings, and gravel and dust roads. ere are salt
marshes in the south western portion that considered suit-
able for halophytic plants and provide food and shelter for a
variety of aquatic birds [3, 4] (Fig 1).

METHODS
e study was conducted during growing season 2016, in the
period between February and July for one trip a week, col-
lected plants were brought to herbarium and subjected ordi-
nary herbarium procedures such as drying, pressing, mount-
ing, labeling and identication. Identication of plant species
were done using data from literatures provided such as [5-8]
the collected and identied plant species were deposited at
national herbarium, Botany department, Faculty of Sciences,
Tripoli University.
RESULTS
At the end of the survey a total of 90 plant species belonging
to 24 families (3 families belonging to monocotyledons and
21 families belonging to dicotyledones) and 76 genera were
collected and identied, of which 24 species and 19 genera
are belong to monocotyledons, and 66 species and 57 genera
are belonging to dicotyledons (Tables 1 and 2).
Floristic analysis were carried out which showed the pre-
dominance of the family Poaceae with 18 species, followed
by the family Asteraceae with 16 species, the result was also
showed the predominance of the genus Juncus with 4 species,
followed by genus Bromus and Lotus with 3 species each, then
the genera Senecio, Hypochoeris, Acacia, Erodium, Mesembry-
anthemum and Malva with 2 species each.

politan in distribution, and the dominance of erophytes and
Mediterranean chorotypes were expected as well because the
study area is located within the coastal Mediterranean region in
which the Mediterranean erophytes are dominating.
As expected, most of the study area are covered and dominat-
ed by true halophytic vegetation, such species are Suaeda vera,
Arthrocnemum macrostachyum, Tamarix aphyla, Kochia indica,
Phragmitis australis, Beta vulgaris, Heliotropium curassavicum,
Mesembryanthemum crystallinum, Mesembryanthemum nodi-
orum, Juncus spp, Lotus cytisoides, Limonium sibthorpianum,
Salsola kali, Trigonella maritima, Tetragonia tetragonoides, and
many others which considered as Euhalophytic species.

This study aims to investigate the coastal plant biodiversity status of Tripoli Province. The result of the survey led to a collection and identification of 130 plant species belonging to 36 families and 105 genera, of which 29 species represented monocotyledons and 101 dicotyledons. Floristic analysis revealed the dominance of the family Asteraceae (24 species) followed by the family Poaceae (22 species). The results have also showed the predominance of the genera Juncus and Lotus with 4 species each. Life form and chorological spectra analyses showed the prevalence of therophytes, represented by 77 species, and the Mediterranean chorotypes with 46 species. Categorization of collected plant species according to their ecological types, revealed a variety of ecological types, with the prevalence of psammophytes, represented by 50 species.

The aim of the present study is to assess the floristic composition and plant diversity of Farwa Island one of the most important Libyan wetlands. The results showed that 130 plant species belonging to 53 families of which 40 dicots, 10 monocots and 3 Gymnosperms were recorded. The most highly represented families are the Asteraceae with 16 species, followed by Amaranthaceae and Fabaceae with 10 species. Floristic analysis was conducted to determine life forms and chorotypes, the highest life forms recorded were Therophytes with 47 species, followed by Hemicryptophytes and Chamaephytes with 25 species for each, then Geophytes with 17 species which the Mediterranean Therophytes are dominating. Chorotype analysis revealed the dominance of Mediterranean plants with 57 species, then Mediterranean / Iranu-Turanean plants with 18 species.

The aim of the present study is to elucidate the floristic composition and to document the current plant diversity of protected area (Researches Station) of Agriculture Faculty, University of Tripoli. The current study revealed that (110) plant species belonging to (95) genera and (35) families (31 dicots and 4 monocots) were recorded from the study area. The most highly represented families are the Asteraceae (22 species), the Poaceae (16 species), and the Fabaceae (12 species). The dominance of Asteraceae and Poaceae families are an indication of the increased diversity of herbs in the area, as well as of the cosmopolitan nature of the families and they are dominated the Mediterranean climate conditions. To determine the floristic composition of plant species in the study area the following characters were studied: life forms, chorotypes and create a list of vascular plants species. According to Raunkiaer's method, the highest life form recorded were Therophytes (52.73 %), Hemicryptophytes (14.54%), and Chamaephytes (13.63%), while the least represented life forms were the Phanerophytes with five species (6.36%) and Nanophanerophytes with three species (2.72 %). The only halophytic plant we registered was Scirpus holoschoenus. The combination of the high percentage of Mediterranean species and the high percentage of therophytes reflects the Mediterranean character of the flora of the studied area. The dominance REPORT

1 The Libyan coast is characterized by many different habitats that are used as stopover sites for many migratory and resident birds. The diversity of Mallaha, which is mainly characterized as a salt-marsh habitat, provides refuge and food for many resident and migrant birds. Mallaha is situated northeast of Tripoli city, and is about 2.5 km in length, with a maximum width of about 1.5 km. The site encompasses dry sandy areas; dry and green grasses; semi-wetland; dry and wet streams and canals; brackish and saltwater pools; a variety of different trees and shrubs, dump yards of various types; ruins of old residential and military buildings; gravel and dusty roads. The area is also rich in salt-marsh habitat. A maximum of 39 bird species was observed (aquatic and marine birds, waders and terrestrial); five species, from a total of seven, are included in appendices I, II and III of the CITES agreement as endangered species in some countries, and two species are listed in the SPA protocol / UNEP / MAP. Moreover, the area is inhabited during winter by some important species, such as the Greater Flamingo (Phonecopterus rubber), the Cormorant (Phalacrocorax carbo) and Swans. Breeding of Little Tern (Sterna albifrons), and Black-winged Stilt (Himantopus himantopus), was recorded during the field visits.

The first evidence of breeding of Marbled Duck (Marmaronetta angustirostris) in Libya, North Africa, is reported. In June 2012, at Mallaha wetland, in Tripoli, Libya, two dead ducklings were found that were later genetically identified as Marbled Duck. This breeding evidence suggests that this and other duck species may breed elsewhere in Libya. Better knowledge on Libyan, and more generally on north African, waterbirds is needed to document the population size and the status of these species. Such information will be important to secure the future of threatened species, such as the Marbled Duck.
