Pregio naturalistico del settore costiero antistante l’ex Ospedale al mare (isola di Lido – Venezia)

Riassunto

Con il presente lavoro vengono esposti i risultati delle analisi sulle comunità vegetali/habitat, flora, fauna e macromiceti presenti in un piccolo ma particolarmente significativo settore di costa del Lido di Venezia. Attraverso tale indagine multidisciplinare si è potuto evidenziare come le diverse analisi concorrano a rafforzare i risultati le une delle altre. Si è cercato anche di dimostrare quali possono essere i vantaggi e i limiti di alcuni approcci di gestione delle coste.

Abstract

Naturalistic value of the coastal area in front of the ex Sea Hospital (island of Lido – Venice)

In this paper we present the results of the analysis of plant communities/habitats, flora, fauna and macromycetes present in a small but very significant sector of the Lido di Venezia coast. The almost total reduction human pressures during about forty years, drives the area to the recovery of habitats of the High Adriatic coast. Among the most significant habitats there are: 1210 – Annual vegetation of drift lines, 2110 – Embryonic shifting dunes, 2130 * – Fixed coastal dunes with herbaceous vegetation (gray dunes), 7210 * – Calcareous fens with Cladium mariscus and species of the Caricion davallianae, 6420 – Mediterranean tall humid herb grasslands of the Molinio-Holoschoenion. All the multidisciplinary assessments show the strengths of the recover paths. The floristic survey led to the discovery of rare species of Veneto, among other Centaurium littorale and Cutandia maritima. The observations on birds recorded the presence of species such as Charadrius alexandrinus and Sternula albifrons in the near the sea sector, and the nesting of Caprimulgus europaeus and Lanius collurio. Even the mycological surveys confirm the ecosystem recover, increasing the consistency between existing and potential conditions.
The paper also shows the advantages and the limits of some coastal management approaches.
