Density, Spatial Pattern and Relief Features of Sacred Sites in Northern Morocco

Sacred sites are of conservation value because of their spiritual meaning, as cultural heritage and as remnants of
near-natural biotopes in landscapes strongly transformed by man. The vegetation of sacred sites in Morocco was
studied recently. Information about their number, spatial pattern or relief position is fragmentary. However, these
parameters are important to evaluate their role as refuge for organisms and their representativeness of potential
natural vegetation.
Therefore, density and spatial pattern of sacred sites on the Tangier Peninsula in NW Morocco were studied based
on records on topographic maps and by ground check. Their relief position was examined calculating a logistic
regression model based on site-presences and random pseudo-absences.
A ground check showed that around 67% of the existing sacred sites are documented in the topographic maps.
They occur in the whole study area but are agglomerated around settlements. Although sacred sites occur with
preference at elevated sites they can be found in almost all relief positions, thus offering the potential of supporting
different types of climax vegetation (climatic climax and pedoclimax). Because of their abundance (around 29
sacred sites / 100 km²) and their distribution pattern they could serve as elements of a biotope network in
degraded landscapes.
