The Park is located in a hill area with typical Mediterranean scrub vegetation, associated with deciduous hardwoods, in some areas thickly mingles with the scrub vegetation. The undergrowth features typical arbutus bushes, also called strawberry trees, viburnum, locally called “legnolano” [woolwood] because it ravels like wool, wild olive, holly and smilax, also called catbrier because of its thorns that catch on clothing like claws. Among the hardwoods the most numerous are without a doubt ilex, turkey oaks, cork-oaks and flowering ash, some of which are very old and stand out because of the large diameter of their trunks. In the surrounding fields grow specimen downy oaks, large oaks planted to give shade to farm workers.
The fauna present in the lake territory is typically Mediterranean. Among the birds, both nocturnal and diurnal raptors are worthy of note. Some large species (harrier eagles and buzzards), are arriving in large numbers, probably in the aftermath of the recent war in the Balkans. The still uncontaminated nature of the area is even a stop along the migratory path of storks; ravens, crows, jackdaws, jays, blackbirds, thrushes and various types of smaller birds (from the sparrow family, various varieties of finches, larks, tits, etc.) can be seen in the Accesa area. The woods are home to wild boars and deer, as well as squirrels, porcupines, , hedgehogs, weasels, beech-marten and hares. Occasionally it is possible to see a four-lined rat snake, a typical area reptile that reaches 2 m in length, but is extremely timid and, above all, harmless. Finally, the area is a habitat for the Mediterranean turtle or “Testudo Hermanni”, that finds in this area optimal reproductive conditions.
