Two main species of marine plants are found in the marine ecosystem of es Carnatge.
The main one is Neptune grass (Posidonia oceanica), which is typical of all of the
bay of Palma and is predominant on the seabed in the most eastern part of es
Carnatge. Neptune grass forms large meadows, which are highly productive ecosystems
with a large number of microhabitats where a wide diversity of species live. Little
Neptune grass (Cymodocea nodosa) can also be found, covering a smaller area than
the Neptune grass and occupying shallow areas with a sandy substrate.
In
the rocky areas found between these meadows, the algae “cistoseira balear”
(Cystoseira balearica), peacock’s tail (Padina pavonica) and “acetabulària
mediterrània” (Acetabularia acetabulum) can usually be found in large quantities,
and if there is sand between the rocks, Halimeda tuna, Dasycladus vermicularis and
“peluqueta” (Codium vermilara) can also be seen.
In the supra-littoral zone,
species typical of marine rocks can be found: Crithmo limonietea, preceded by the
lichen Verrucaria amphibia in the zone closest to the sea. It is also worth noting
the presence of a species, Hildenbrandia prototypus.
Diverse marine fauna
can be found thanks to the range of habitats here. Molluscs are also worth noting,
with species such as the common pandora (Patella sp.), the spiny-dye murex
(Haustellum brandaris), turban shells (Astraea rugosa), ceriths (Cerithium
vulgatum) and the small periwinkle (Littorina neritoides). The marbled rock crab
(Pachygrapsus marmoratus), sea urchins, like the purple sea urchin (Paracentrotus
lividus) and sea anemones (Actiniaria sp.) can also be found here. Some examples of
the noble pen shell (Pinna nobilis), a protected species, have been found.
A
pair of Mediterranean monk seals (Monachus monachus) lived in the cove of es Gató
in the first decade of the twentieth century. Until the start of the twentieth
century, there were stable colonies of this species in much of the Balearic Islands
but it is now on the list of the 10 species at the greatest risk of
extinction.5

LOW-RISK BATHING AREA
Plants’ survival in the coastal land environment of Es Carnatge is connected to
them being adapted to the requirements of the area, such as being resistant to
drought, salinity, wind and the sandy substrate.
The predominant coastal
species in Es Carnatge are: samphire (Crithmum maritimum), sea lavender (Limonium
companyonis), the gold coin daisy (Asteriscus maritimus) and tree purslane (Atriplex
halimus). From Punta del Reflector to Cala Pudent, alkali seepweed (Suaeda vera) and
glaucous glasswort (Arthrocnemum macrostachyum) are abundant. Other coastal species
worth mentioning are grey bird’s-foot-trefoil (Lotus cytisoides), the horned poppy
(Glaucium flavum), common shrubby everlasting (Helichrysum stoechas), sea heath
(Frankenia laevis), Algerian tea (Paronychia argentea), Asparagus horridus, European
searocket (Cakile maritima) and salt cedar (Tamarix sp.), which is the only shrub in
this coastal zone.
In the Camp de Tir area, close to the promenade, shrubby
species grow such as false yellowhead (Dittrichia viscosa), sterile oat (Avena
sterilis), annual saltmarsh aster (Aster squamamatus), field bindweed (Convolvulus
arvensis), chicory (Cichorium intybus), summer asphodel (Asphodelus aestivus) and
silvery plantain (Plantago albicans).
Further inland, before reaching the
promenade, there are shrubby species adapted to the fossil dune soils like grey
bird’s-foot-trefoil (Lotus cytisoides) shaggy sparrow-wort (Thymelaea hirsuta), felty
germander (Teucrium capitatum), “fumana” (Fumana laevis) and yellow rockrose
(Helianthemum marifolium (L.) Mill. subsp. origanifolium), a plant classed as being
at risk of extinction, which in all of Mallorca is only found in this area.
On
the inland side of the promenade, a project to create artificial dunes and
plantations has been implemented. This area has woodland with “savina” (Juniperus
phoenicae subsp. turbinata) and other species such as Aleppo pine (Pinus halepensis),
Spanish moon trefoil (Medicago citrina), albaida broom (Anthyllis cytisoides), joint
pine (Ephedra fragilis), the mastic tree (Pistacia lentiscus), rosemary (Rosmarinus
officinalis) and the white-leaved rock rose (Cistus albidus).5
There is very little mammal fauna in Es Carnatge as it is in a built-up area
and has a large amount of human activity.
Among the vertebrates,
the most interesting group is the birds. Various species of sea bird can be seen in
the area of es Carnatge owing to its coastal nature. The shag (Phalacrocorax
aristotelis) can often be seen on the rocks or swimming to find fish. It is also
common to see the Caspian gull (Larus cachinnans), Audoin’s gull (Larus audouinii),
which is endemic to the Mediterranean. The Balearic shearwater (Puffinus
mauretanicus), which is endemic to the Balearic Islands and at risk of extinction,
can also be seen, albeit less commonly. In winter the black-headed gull (Larus
ridibundus) and the cormorant (Phalacrocorax carbo) are also common.
In
addition, the Sandwich tern (Sterna sandvicensis), the Kentish plover (Charadrius
alexandrinus), which is a protected species, and the ringed plover (Charadrius
hiaticula) can also be seen more frequently. Other birds that can be seen on the
coast are the common sandpiper (Actitis hypoleucos) and the ruddy turnstone (Arenaria
interpres).
As for birds found on land, the African stonechat (Saxicola
torquata) can often be seen in trees. It is also quite common to see the blackbird
(Turdus merula), the house sparrow (Passer domesticus) and the Sardinian warbler
(Sylvia melanocephala). The hoopoe (Upupa epops) and Thekla's lark (Galerida theklae)
are found there less frequently. Robins (Erithacus rubecula) and meadow pipits
(Anthus pratensis) come to these spaces in the winter.
The pine wood area is
home to typical woodland species, such as the goldfinch (Carduelis carduelis), the
greenfinch (Carduelis chloris), the serin (Serinus serinus) and the wood pigeon
(Columba palumbus). The swift (Apus apus) and the kestrel (Falco tinnunculus) are
often seen over Es Carnatge.
As for invertebrate fauna, it is worth noting the
presence of the Pimelia criba beetle, a species endemic to the
Balearics.5
Major deposits of sandstone can be found in the area of es Carnatge, formed by the
cementing of sand from the dunes that were created during the penultimate glacial
period, 200,000 years ago. This glaciation caused a fall in sea level, leaving
large amounts of marine sand exposed to the action of the wind and leading to the
formation of dunes, which were later cemented as sandstone deposits. The quarries
reveal the wave-like structure created by the action of the wind, the imprints of
roots, of fossilised invertebrates and footprints of a vertebrate fossil, the
Myotragus balearicus.
One of the Balearic Islands’ most important
archaeological sites from the Late Pleistocene is found in Cala Pudent and in the
houses of es Carnatge.
There were long glacial periods during the
Pleistocene. In an ice age there are colder eras called glacial periods, where the
ice advances, and interglacials where it retreats. This alternation is marked by
fluctuations in sea level that leave their mark as forms of erosion or as
accumulated deposits compared with the current level.
The deposits that can
be seen in the central area of Cala Pudent comprise fossils superimposed with fauna
favouring warm conditions. At the top, there is a reddish-yellow extract with land
molluscs and bivalves. Beach deposits with abundant Strombus bubonis (fauna typical
of warm locations and currently still found in Senegal) are found over these layers
and finally there is yellow mud with land molluscs.
The other major site is
located opposite the houses of es Carnatge, where beach deposits with Strombus
bubonis can be made out, separated by a thin layer of red mud. The upper layer is a
beach conglomerate with numerous Acar plicata fossils. 5
