The current study was carried out on the riparian vegetation of Lund Khuwar, Kaloshah, District Mardan. During research 77 plant species belonging to 61 genera and 36 families were observed and described ecologically. Asteraceae having 8 genera (13.11%) and 10 species (12.98%), followed by Poaceae which was represented by 8 genera (13.11%) and 8 species (10.8%). Lamiaceae having 4 genera (6.55%) and 4 species (5.19%) and Moraceae had 3 genera (3.91%) and 4 species (5.19%). The leading genera were Acacia and Chenopodium with 3 (4.91%) species each. Genera like Amaranthus, Euphorbia, Juncus, Marsilea, Morus, Populus, Polygonum, Tegetes, Zinnia and Zizipus were consisting of two 2 (3.27%) species each. There were 2 (5.55%) families of Pterediophytes which were consisting of 4 (5.19%) species and 3 (4.91%) of the total genera. There were 4 (11.1%) families of Monocotyledoneae with 12 (15.85%) species and 30 (83.83%) families of Dicotyledoneae. The dicot families comprised of 61 (79.22%) species of the total number of species. Life form, leaf size, phenology and abundance classes were also determined during present study. The plants were identified with the help of available literature (Flora of Pak). The plants were submitted to the Herbarium of Centre of Plant Biodiversity, University of Peshawar, Pakistan.
Riparian vegetation; Ecological evaluation; Life form; Leaf size; Lund khwar
The name "Lund Khwar" literally means "the ever-flowing stream or brook". Archaeological and historical evidence clue towards the Gandharan era. Lund Khwar is a historical village and union council of Takht Bhai Tehsil in Mardan District of Khyber Pakhtunkhwa, Pakistan. The district lies from 34° 05 to 34° 32' north latitudes and 71° 48' to 72° 25' east longitudes.
It is located at 34° 23' N 71° 59' E, with an altitude of 371 m (1220 feet). It is located 18 km from Takht Bahi, 10 km from Sher Garh and about 30 km from Mardan on the National Highway between Swat and Peshawar District. The town is surrounded by two main streams and a smaller brook from 3 directions which flow throughout the year. It is bounded on the north by Buner district and Malakand protected area, on the east by Swabi and Buner districts, on the south by Nowshera district and on the west by District Charsadda. Mardan district may broadly be divided into two parts, north eastern hilly area and south western plain. The entire northern side of the district is bounded by the hills. The highest points in these hills are Pajja or Sakra, 2056 m high and Garo or Pato, 1816 m high. The south western half of the district is mostly composed of fertile plain with low hills strewn across it. The climate of the research area is moderate. The summer season is extremely hot. A steep rise of temperature observed from May to June. Even July, August and September record quite high temperatures. During May and June dust storms are frequent at night. The temperature reaches to its maximum in the month of June i.e. 41.50"C. The coldest months are December and January. The mean minimum temperature recorded for the month of January is 2.09° C. Most of the rainfall occurs in the month of July, August, December and January. Maximum rainfall recorded for the month of August 125.85 mm. towards the end of cold weather there are occasional thunder storms and hail storms. The relative humidity is quite high throughout the year while maximum humidity has been recorded in December i.e. 73.33% . Many studies for listing floristic diversity and its ecological evaluation have been done in different area. Some of the prominent are Haq et al. documented the ecological characteristics of twenty one species of Onion crop from University of Peshawar, Botanical Garden, District Nowshera . Reported 186 species from Santh Saroola, Kotli Sattian, Rawalpindi, Pakistan.  Identified 93 plant species belonging to 67 genera and 30 families including Phanerophyte with the large number of species (37), Therophyte (33), Chaemophytes (12), Hemicryptophyte (6) and Cryptophyte (3). The riparian zone is the place where aquatic systems merge with the other terrestrial environment. Virtually all rainwater runoff must pass through the zone before moving into adjacent aquatic/estuarine systems . Riparian vegetation reduced periphyton growth in pasture streams and influences the composition of the macro invertebrate community. The vegetation canopy shades incident light and reduces water temperatures thus influencing primary productivity . Loss of riparian vegetation can decrease the amount of suitable habitat for riparian and aquatic fauna such as fish and invertebrates, thereby reducing stream productivity and fish carrying capacity . Plant diversity and ecological characteristics are important in term of land degradation and erosion [7,8]. Conducted their research on linkages between spatial variation in riparian vegetation and floristic quality to the environmental heterogeneity of River Soan and its associated streams. People interpret rivers as a carriage where they dump all the garbage and let out sewers into the waterways [9,10]. Identified 21 species belonging to 14 families as riparian plant species from Korang river, Islamabad.
Materials and Methods
Regular study tours were made to the research area during March 2014 to May 2015 in the blooming period of the plants to collect plant specimens and all the related ecological information about the riparian plants species. Plant specimens were collected carefully with their full structure (stem, leaves, flowers etc.) from different parts of Lund Khuwar. During the process of collection photographs were also taken through Digital Camera. After collection specimens were placed in folded newspapers, dried and pressed for about two weeks to get them moisture free. At the same time the plants were numbered and marked with data, location and other characteristics of species. Plants identification was carried out with the help of available literature [11-15]. Ecological characteristics of plant species were known after Raunkiaer  and Hussain . The vouchers specimens were deposited at Centre of Plant Biodiversity University of Peshawar Herbarium (UPBG).
Results and Discussion
During the study there were total 77 species belonging to 61 genera and 36 families constituted of the riparian vegetation of the study area. Asteraceae was the leading family and was represented by 8 genera (13.11%) and 10 species (12.98%) followed by Poaceae which was represented by 8 genera (13.11%) and 8 species (10.8%) followed by Lamiaceae had 4 genera (6.55%) with 4 species (5.19%). Malik et al. also studied these families were well represented in Kotli Hill during monsoon . Durrani et al. also observed that these families were dominant in their research areas . Badshah et al. also documented these families in their study from the rangeland of District Tank, Pakistan . Hussain et al. also expressed that Ateraceae and poaceae was the leading families in their studies from Mastuj valley, Hindukush Range, Pakistan .

There were 4 (11.1%) monocot families having 12 (15.85%) species. Cyperaceae, Juncaceae, Poaceae and Potamogetonaceae were the monocot families found in the riparian zone of the study area.
The remaining 30 (83.83%) families were Dicot. The dicot families comprised of 61 (79.22%) species. Acanthaceae, Aizoaceae, Amaranthaceae, Asclepiadaceae, Asteraceae, Bignoniaceae, Brassicaceae, Cannabaceae, Caryophyllaceae, Chenopodiaceae, Convolvulaceae, Euphorbiaceae, Fabaceae, Lamiaceae, Maliaceae, Mimosaceae, Malvaceae, Moraceae, Myrtaceae, Nyctaginaceae, Oxalidaceae, Papilionaceae, Polygonaceae, Rhammaceae, Rosaceae, Rubiaceae, Salicaceae, Simarubiaceae, Solanaceae and Verbinaceae were the dicot families in the research area as shown in GRAPH 3.
Biological spectra expressed that therophyte were the dominant life form class having 7 (19.44%) families, 28 (45.90%) genera and 40 (1.94%) species followed by Megaphanerophyte with 7 (19.49%) families, 9 (14.75%) genera and 9 (11.68%) species of the total plants. Costa et al. also documented 47 families including 42.9% therophytes, 26.3% phanerophytes, 15.8% chamaephytes, 12.8% hemicrytophytes and 2.3% cryptophytes . The second leading life form class was Geophyte which was consisting of 5 (13.88%) families, 6 (9.83%) genera and 6 (7.79%) species. These were then followed by Hemicryptophyte had 4 (11.11%) families, 6 (9.83%) genera and 6 (7.79%) species. Nanophanerophyte was the fourth class with 4 (11.11%) families, 4 (6.55%) genera and 7 (9.09%) species of the total plants. Chamaephyte was consisting of 3 (8.33%) families, 3 (4.47%) genera and 3 (3.89%) species. Macrophanerophyte possessed 3 (8.33%) families, 2 (3.27%) genera and 3 (3.89%) species, while Mesophanerophyte and Microphanerophyte were consisting of 1 (2.77%) families, 1 (1.63%) genera and 1 (1.29%) species each. Our present findings are agreement with that of [20,21,23-26] who also reported dominance of therophytes in (Table 2(A)). The dominancy of Therophytes indicates the harshness and longevity of winter season .
