rom Christchurch one of the better trips is
around Banks Peninsula. Banks Peninsula is made up of the remnants of two basaltic
volcanoes, Lyttleton and Akaroa, which became extinct about five and a half million years
ago. Until the recent geological past this area was an island, but was joined to the
mainland by the gradual eastward movement of the Canterbury Plains. Cook thought that
Banks Peninsula was an island when he sailed past, but at this time it was already part of
the mainland.
On your way make a stop at Riccarton or Deans Bush, three kilometres
west of Cathedral Square, along Riccarton Road. This is the only remnant today of the
swamp forest which once flourished around Christchurch and good examples can be seen here
of totara, matai, kahikatea and rata with a good selection of regenerating growth.
From Riccarton take Highway 75 through Taitapu and Motukarara to
Birdlings Flat at the north-cast corner of Lake Ellesmere, from where a detour to Lake
Ellesmere is recommended. Its actual size varies considerably, depending on such factors
as tides and inflow, from some 20,000 hectares to almost 24,000 hectares.
In keeping with its size, Lake Ellesmere is home to our largest
populations of Canada geese, and black and white swans are found here along with countless
ducks and waders. Some 158 species have been recorded at Ellesmere, of which 80 are
regular users.
One of the names the local Ngai Tahu gave the lake was Te Kete Ikaa
Rakaihautu, 'the food basket of Rakaihautu. They used the reeds and flax for weaving, the
waters for transport and the mud for dyes. More importantly, as the kumara was at its
southern limit and thus probably a marginal crop, they relied on the lake for much of
their food, catching large numbers of eels, flounders and other fish. They also hunted
birds,several to extinction, including the native swan, goose and Finschs duck.
From Ellesmere continue on around the peninsula to the French
settlement of Akaroa on Akaroa Harbour. In the harbour Hectors dolphin can often be
found - it has the unenviable title of being the world's rarest marine dolphin. Being an
inshore species it is especially vulnerable to being caught in set nets and an estimated
one third of the population has died recently in the nets. In an effort to protect it some
1140 square kilometres around the peninsula have been declared a sanctuary.
Little Blue Penguin
The white-flippered penguin also occurs around Banks Peninsula. Opinion
is divided as to whether this is a full species or merely a subspecies of the little blue
penguin. After breeding it disperses to feeding grounds elsewhere and young birds have
been found as far north as East Cape and as far south as Otago. Another bird worth
watching for is the spotted shag, which breeds in crevices in the cliffs. Tours are
available to see both dolphins and seabirds from Akaroa township.
From Akaroa take the road back to Christchurch via Pigeon Bay and
Ohinetahi. Few sizeable areas of standing timber remain on Banks Peninsula, but what there
is is mainly in reserves, some of it around Pigeon Bay.
