Study area description
Serralada Litoral Park is mainly covered with woodland, although there are also sections of farmland and more open areas, especially in the middle of the park, which help increase its biodiversity.Pine and holm oak woods are the two most predominant forms of vegetation. Its bright pine forests of umbrella and Aleppo pine, on the Maresme side, contrast with the better conserved forest of holm oak, mixed with white oak, on the greener, wetter slopes of the Vallès side.
Brush and scrubland are mainly found on the Maresme slopes, spreading over old vineyards and areas affected by forest fires. The few water courses in the park, fragile arteries running through the landscape contrasting with the dryness of the Mediterranean forest, are home to European alder, white poplar and hazel, mixed with reeds and plantations of black poplars and plane trees. These are vulnerable habitats, strongholds for the threatened species that find refuge in the park.
Gastropod communities in various natural environments and conchological species of interest for conservation are also described. Several environmental aspects that determine the distribution and abundance of snails are discussed and management m.easures to meet their ecological requirements are suggested.
