"Senecio gallicus", an annual plant of the "Senecio" genus and a member of the Asteraceae family is also one of those species who colonizes in isolated habitats where the environmental conditions could qualify as being difficult -- widespread across southern France and the Iberian Peninsula in deserts and xeric shrublands, on steppes and salty dry coastal plains. "S. gallicus" is playing a predominant role in shaping patterns of genetic structure by presenting models of historical associations among population rather than patterns of ongoing gene flow.cite journal

:Typical of the tenacious genus "Senecio", the small shrub Azuzón de Alborán colonizes areas that could be described as disturbed and unstabilized as it does live where there is an accumulation of volcanic ashes and shell laden sand, historically perturbed by natural events and human activities. Also typical, this species produces three generations of plants each year and is non-competitive; the middle generation of "S. alboranicus" shares its part of the island with "Lavatera mauritanica" and "Anacyclus alboranensis". Atypical of the genus, this species is a halophile, growing in soils with a known high concentration of salt.cite book

:Azuzón de Alborán can be found growing at altitudes between convert|0|m|ft and convert|15|m|ft. The restricted size of the island and the rarity of the habitat make Azuzón de Alborán particularly vulnerable to changes. Climatic conditions (quantity and distribution of rain, soil salinity, etc.) and human activities (the lighthouse was once manned); there have been large fluctuations in the numbers of individuals each year. These fluctuations affect not only the number of individual plants but also their size and the number of flowers. The decline of this species could be caused by alterations generated by human presence (military occupancy, artificial environments, etc.) in addition to events like natural changes or biotic threats (competition, parasitism, diseases, etc.), alterations which probably not coincidentally describe many of the conditions that occurred from the mapping those years.
