Landscape
and Wildlife notes
This walk follows a route through quiet residential roads, but there
is scope for interesting
diversions along the way.
Point
2 This lane has a rural feel with a tall hawthorn
hedge and verge with wild flowers such as cow parsley and stinking
iris. This iris is most noticeable in the autumn and winter when
its bright orange seeds are held a three-part seed case. Cow parsley
is one of the first plants to show fresh new growth in the late
winter; it has flat white heads of creamy white flowers in summer.
Different species of this family flower over long period from spring
through the summer. Ivy can also be seen in many places. It is one
of the few plants that flower in late autumn so provides a good
source of nectar for insects during a difficult time of year. The
black berries are food for blackbirds, starlings and wood pigeons
in spring, again when times are hard.
Point
3 The view of Oxford must be one of the best in
the area. The towers and spires of Oxford are well known, but this
is a good spot to see how the city is situated in the landscape.
It originally developed at a fording place of the river, hence the
name. The flat river plain is in marked contrast to the surrounding
hills, both at Botley to the west and at Headington and Shotover
in the east. The plain was formed by the action of the river over
thousands of years, flooding the land and depositing silt. Hinksey,
on the edge of the river plain, was a settlement on a drier area.
The "ey" part of the name means "an island".
The hills are much drier with free- draining limestone often close
to the surface as on the rough track alongside the open field. Water
percolates through limestone to emerge as springs where the water
table meets impermeable clay. Along this ridge there are several
quite steep valleys formed by this action. The rough grassland on
the hillside contrasts with the nearby gardens. Look out for another
member of the cow parsley family here. This is wild carrot, which
flowers later in the summer. The flower often has a small dark flower
in its centre, which attracts pollinating flies in search of a mate.
Unlike other cow parsleys, the seed head folds in on itself, rather
than remaining umbrella shaped.
Point
4 & 5
Look out for a variety of interesting plants in the gardens which
adds to the local biodiversity by providing extra nectar and food
sources, as well as shelter, particularly in evergreens during the
winter. Some gardens contain old fruit trees, whilst others have
box, larch (England's only native conifer) and a range of exotic
conifers from all over the world. Hedges can also be very varied
- notice the old field hedges composed mainly of hawthorn, compared
to laurel, privet and beech amongst many species to be seen. Beech
retains its brown autumn leaves until the spring, thus providing
some added shelter for birds and small mammals.
Across
the road at Point 5
in Harcourt Hill is Raleigh Park, which can be accessed by a public
footpath. This has good areas of wildlife interest so would be well
worth exploring.
Point
5c The benefit of fresh clean water was recognised
in the early 17th century when a Conduit House was built to collect
water from nearby springs to be piped to Carfax in Oxford to provide
pure water to Oxford residents. See information board.
