(24.9) Environmentally sensitive ecosystems
some ecosystems are more
fragile
and less resistant to
change
than others
often referred to as
environmentally sensitive ecosystems
(ESE)
For example tourisms can bring in
economic vitality
to an area however it can also bring change that is
not always positive
such as
overdevelopment
of the coast
This can lead to
losses
in the
biodiversity
of the region
In meny ESE's the same type of management is used:
introducing
anti-poaching measures
replanting
of forests and native plants
controlling
the movement of livestock
limiting hunting
through quotas and seasonal bands
Limiting
the areas tourists can visit
Galapagos islands, pacific ocean
an
archipelago
of volcanic islands
of special interest because they have not been connected to the mainland
so the flora and forna had to survive a crossing of hundreds of miles of ocean
The majority of animals are reptiles
There is only one spies of land mammal the
rice rat
it arrived by being
washed away
from mainland river banks
floating
on
rafts
of
vegetation
Galapagos giant tortoise
control of human activates
Galapagos national park was established in 1959
limiting human access to particular islands, or specific parts of the island
controlling migration to and from the island
introduction of parke rangers across the island
strict control over movement of introduced animals such as pigs
