Check list of flora and vegetation of Hafer Albatin region, northeastern Saudi Arabia

摘要

The piece of work has been designed tostudy the present–day vegetation and document the flora of wild plant of HafrAl–Batin region northeastern Saudi Arabia. During this survey ,specimens werecollected randomly from different sites during two successive year (2014 –2016)a total of 83species of plants were identified, belonging to 21 families(16monocotyledonous from 5 families and 67dicotledonous from 16 families wererecorded. The most highly represented families were Asteraceae was the richest (23species) 28% followed by mimosaceae (7 species) 8.5% and Poaceae (6 species each) 7.3% over of abundance have beenEstimated plenty fullness of a species of target group according to apredefined scale The most important plant species were either major dominantspecies, like Schimperaarabica,Rumex vesicarius, Launea nudiculis, Malva parviflora ,citrulluscolyocynthis ,Stipa capensis . Plantago boissieri or rare endangered andvulnerable such as Artemisia sp, Haloxylon salicornicum , Calendulatripterocarpa and rare species such as Acasia tortilis . Check list of florademonstrated high annual plant diversity (56.5%) and perennial (43%) thediversity of species corresponds higher means of percentage cover during rainyseason in winter at the study area. Future effective conservation andmanagement plans has been needed to the present day vegetation cover andfloristic composition in the study area as it contains important species forsustainable development, preservation of biodiversity through the wild plantsand endangered for a better environmental future.
