Tuscania Nature Reserve
Plant and animal life
The park hosts within its boundaries no less than two Sites of Community
Importance (SCI): SCI IT6010020 Marta River (upper portion) and SCI IT60100036
Tuscania Cork Grove, selected and mapped by the EU as a result of the presence
of threatened habitats and species and for this reason considered areas of particular
environmental interest. The course of the Marta, however, represents the heart
of the Park. Along this river, above all in its northern portion, there are wide
swathes of hygrophilous and riparian vegetation: poplars, elders, willows and
stretches of reeds. Here the waters still teem with fish, including dace (Leuciscus
souffia), brook lamprey (Lampetra planeri), shad (Alosa fallax), South European
roach (Rutilus rubilio), barbel (Barbus plebejus) and brook goby (Padogobius nigricans)
all species of Community interest, extremely important from a naturalistic point
of view since they are threatened with extinction.In the vicinity of the small
springs, clumps of elders shade ferns which are also quite rare
such as the maiden-hair fern (Adiantum capillus-veneris), while near
the water nest the penduline titmouse (Remiz pendolinus), the rare pied kingfisher
(Alcedo atthis) and quite often you will hear the unmistakable song of Cetti's
warbler (Cettia cetti). Moving to the downstream area of the valley of the
Marta, where the tufa ravines widen into wider sedimentary valleys, the best developed
forest growth on the slopes is that of cerris oak groves (Quercus cerris) and
mesophilic woods with hornbeam and cornel, while in the open, sunnier areas we
find prevalence of thermophilic vegetation, often of the Mediterranean brush type,
with ilex (Quercus ilex), lentisk, heather, numerous scattered cork trees, accompanied
in the cooler areas by plants typical of deciduous oak woods such as pubescent
oak (Quercus pubescens), maple and ash. With such diverse vegetation, interspersed
with open areas used for grazing and crop growing, animal life is also be rich
and varied. Apart from the species already mentioned, we must highlight the abundant
presence of the wild boar
(Sus scrofa), which reigns supreme in this environment, the porcupine
(Hystrix cristata) and bird species such as the tawny owl (Strix aluco), the golden
oriole (Rigogolus canorus), the rare roller (Coracias garrulus), the hobby (Falco
subbuteo), the kestrel (Falco tinnunculus), the sparrow-hawk (Accipiter nisus)
and the numerous sylviids which inhabit the Mediterranean brush. It is interesting
to note the nesting habits of species associated with cereal crop and traditional
grazing habitats, such as Montagu's harrier (Circus pygarcus), the quail (Coturnix
coturnix) and no less than three species of larks: the wood-lark (Melanocorypha
calandra), the crested lark (Galerida cristata) and the skylark (Alauda arvensis).
