This site provides a list of species based on herbarium (5550 exsiccata) and field images (hundreds of images: landscapes and flora) harvested in Algerian Far East for thirty years.

How and why have I collected these data?

My professional route, parallel to my religious commitment, answers this question. Some pointers:

Available materials

50 to 60% of exsiccata and photos – that is to say the greater density - cover, primarily, what botanists call Numidia (Quezel & Santa 1962-1963), is the geographic division along the Tunisian border to the height Souk Ahras in the East, limited to the West at the base of Skikda and south to the mountains of Medjerda and Guelma.

The others are distributed from Numidia towards south between the regions of Guelma, El Harrouch, Constantine (in particular Jebel Ouahch), Tebessa Bir el Ater and Negrine, Khenchela, Batna (fortunately endowed with a national park: the Belezma) Ghoufi, Biskra, Ghardaïa and El Golea (now El Menaâ). The statement’s density is lower, but few botanists have covered or cover some of these areas.

It seems necessary to pinpoint the extension area of some species and, particularly in the High Plains, some families including Crucifereae; Indeed, this ecosystem is deemed to be a dispersal area (worldwide, more than 4% of the taxa of this family are present). In addition, the High Plains have many chotts or sebkhas, from which a major part of the flora originates.

Biogeographical interest

So many motives to leave traces in our floristic investigations in this area, to make them available, first off course for nationals, but also researchers from the scientific community, who frequently seek our assistance for a particular species and with whom we work and publish.
