Hey im makeing a research about plant that i can fing in 900 m or more above sea level so i know what to look for when i go to my home town ,, its an amazing place i'll be posting pics for it later and its about 1000m - 1100 m above sea , so anyone have any suggestions ?

Is your research geared towards a particular category of plants? If you narrow down your request or provide more precise description of what it is you are covering in your research, it might be easier (for myself and others) to reply to your question.

All the best with your research.

and its in the mountains , in the Mediterranean Basin if that helps

well im lookin for wild acacias , Delosperma cooperi , Lespedeza bicolor var. japonica , and Mimosas

900 meters above sealevel is really high. Perhaps Trichocereus Peruvianus & Trichocereus Pachanoi,
growing high in the Andes mountains, might qualify.

Other high growing plants are Acacia Phlebophylla(endangered species), growing 350 meters above sea-level,
& possibly Acacia Alpina too.

Allthough these plants are not native to the Mediterranean region, it could be that in the more arid & dry areas some of these plants may have become naturalised.

Are you talking about the Pyrenees mountain range? Does that get higher than 900m above sealevel? o_O

no im talkin about the mountains in lattakia Syria , we have mountains here up to 1200 m above sealevel , my village is about 1100 m or 1150 m , and im goin up thr next week and ill go in a trip in the forest to look for plants , its a trippy place though , its very cold but very spiritual

here are some pics

Thete must be a huge number of plants that can live and thrive at those altitudes. Life is so tenacious

thanks pandora , i know im just making a list of plants and pics of what to look for so i dont get a bit lost up thr

Ok, a reputable field guide (or several) could potentially be useful to your location specific plant identification. A point of interest (maybe not directly relevant to your request but can provide context) is how a single plant can exist and adapt to significant variations in height above sea-level. In some countries elevated plateaus, often higher than 1000m asl., subject plants to contrasting environmental conditions. From my own experience, I've come across an Acacia species (Acacia karroo in this particular instance) at two drastically different localities; A xeric Mediterranean environment (Winter Rainfall Zone) ~10m asl. and another specimen located in a grassland savannah (Summer Rainfall Zone) ~1400m asl.
