Prunus lusitanica L. is a tree which presents an outstanding botanical interest.
In the present work, the distribution, the physical medium and the vegetal groups of
this species on the Iberian Peninsula have been studied.
In order to carry out this work, most of the information about this species
generated for the last 30 years has been collected in the first place.
Later, a survey of all the places included by the available bibliography was
carried out, and also a search around neighbouring areas and other ones with similar
characteristics. During this survey, 133 locations of the species in the Iberian
Peninsula have been described, of which 25 were discovered during the field work.
This survey has served to make cartography of plants in the Iberian Peninsula, scale
1:25.000 in Portugal and 1:50.000 in Spain. It has also served the collection of plants
data and physical medium data (lithological and physiographic mainly).
At a later stage, new data about the physical medium have been collected
(edaphic and climatic mainly).
All the data collected during the two previous stages have been analysed in
order to obtain the common features of all locations on the one hand; and, on the
other hand, the particularities of each geographical area of the Iberian Peninsula
inhabited by the above mentioned species.
