OBJECTIVE 1 – IMPORTANT AREAS
FOR THE BOTTLENOSE DOLPHIN
Identify the areas of importance for
the bottlenose dolphin in the coastal
waters of Madeira, with the aim of
establishing adequate marine Natura
2000 sites for the species

uneven distribution,
with higher estimated
dolphin densities in
the southeast, east
and northeast of
Madeira and South of
Porto Santo. The area
distribution tends to
be in waters less
than 2000m deep, with
higher presence in
bellow the -1000m
bathymetry.
-Around 180 animals use the
Madeira waters regularly and
can be considered resident or
animals associated with the
islands
OBJECTIVE 1 – IMPORTANT AREAS
FOR THE BOTTLENOSE DOLPHIN
WHAT HAVE WE LEARNED ABOUT THE SPECIES?
RESIDENCY, SAZONALITY AND HABITAT USE
The bottlenose dolphins
use these waters all
year around
Resident and transient animals use these waters for
activities crucial to their survival such as feeding,
reproduction, calving, socialising and resting
All groups Groups without calves Groups with calves
Groups feeding Groups socialising Groups resting
OBJECTIVE 1 – IMPORTANT AREAS
FOR THE BOTTLENOSE DOLPHIN
WHAT HAVE WE LEARNED ABOUT THE SPECIES?
HABITAT USE
The bottlenose dolphin distribution
coincides partially with the area of
most human activity in the coastal
waters of Madeira (Southeast),
namely marine traffic including
whalewatching.
This species is one of the most
targeted species by whalewatching
because of its year around presence,
abundance and coastal distribution
WHAT HAVE WE LEARNED ABOUT THE SPECIES?
INTERACTION WITH HUMAN ACTIVITIES
OBJECTIVE 1 – IMPORTANT AREAS
FOR THE BOTTLENOSE DOLPHIN
In light of present knowledge about bottlenose
dolphins in Madeira coastal waters, the a
establishment of a SCI for this species is
fully justifiable
OBJECTIVE 1 – IMPORTANT AREAS
FOR THE BOTTLENOSE DOLPHIN
SCI APROVED BY THE MADEIRA GOVERMENT
(resolução 699/2016)
The area covers all
coastal waters
around Madeira,
Porto Santo and
Desertas Islands
from 1 nautical
mile off the coast
to the limit of the
polygon that
corresponds roughly
to the -2500m
isobath, with a
total surface area
of 6351 km2
OBJECTIVE 1 – IMPORTANT AREAS
FOR THE BOTTLENOSE DOLPHIN
Encompasse the critical habitats of the species
in Madeira coastal waters, namely, feeding,
calving, resting, and socialising areas
SCI PROPOSED AREA IS DESIGNED TO
Accommodate the
natural changes in
range and areas of
species distribution
Contribute for the interconnectivity and ecological coherence
of Natura 2000 network - can be a stepping stone for bottlenose
dolphins travelling the Atlantic between regions with SCI, such
as, the Azores, Canary Islands and Portugal and Spain mainland
OBJECTIVE 1 – IMPORTANT AREAS
FOR THE BOTTLENOSE DOLPHIN
OBJECTIVE 1 – IMPORTANT AREAS
FOR THE BOTTLENOSE DOLPHIN
THE SCI ENCOMPASSES PARCIALLY OR TOTALLY THE DISTRIBUTION OF
OTHER CETACEAN SPECIES IN MADEIRA COASTAL WATERS
