Before you
walk down the other side of the lake, stop at the top of it. If it is
a Sunday, you can watch the remote controlled boats that people have been
bringing to this smaller section of the lake for years.
If you look
around you can see a variety of trees in the park including beech, oak
and horse chestnut whilst along the river section there are willows and
more horse chestnuts.
This area
of the park is highly used by the general public, and because a lot of
wildlife doesn't like disturbance, you will find more common species in
the scrub and hedgerows around here that are more used to people. These
include rabbits and all kinds of garden birds like House Martins, blackbirds,
chaffinches, robins and tits and of course, pigeons - all of which are
fairly bold!
Flocks of
swallows have been seen feeding over the lake and more unusual birds such
as the Greater Spotted Woodpecker have also been seen.
But at dusk,
the bats come out!
They roost
in the trees along the river and in surrounding buildings and like to
forage along linear habitats such as in the rows of trees along the river
to the left. This is because being in a line not only protects them from
predators, it also aids their orientation and their echo location course.
The bats
usually hibernate from late September to late March but at dusk during
the summer months, many bat species can be seen feeding on insects over
the lake and along the river. These include the common pipistrelle, soprano
pipistrelle, daubentons, Brown Long-eared and whiskered bats.
They have
amazing body clocks and different species come out at different times.
The pipistrelles come out about 20 minutes after sunset, while noctuals
leave it 40 minutes.
Artificial
nature
You are again walking along where the river used to flow, but over the
years it has been moved to the left and 'canalised', but this is a process
that has made it unsuitable for many typical chalk stream species.
The canalisation
of his section of river means that it has a very slow flow, much slower
than a typical chalk stream so it breaks the continuity of the chalk stream
habitat that the rest of the Ver enjoys.
So, the river
on your left is now not great habitat because it is no longer natural.
It is all the same level so doesn't get a fast flow of water through it.
As a chalk stream, the Ver should normally be associated with brown trout
and have water voles on the banks but this artificial bank is not suitable
for them. It's far too open.
This kind
of slow flowing water also attracts ground dwelling fish like carp which
stir up the sediment and make the water look quite murky. All the crayfish
that used to be here have long gone. Further downstream the water gets
faster and is therefore better oxygenated and can support more wildlife.
There are
not many plants here. Planting more vegetation would lead to a greater
insect population to feed larger species and also provide good egg laying
sites for newts and frogs - although it would probably have to have nets
put over it to stop the geese eating it all first!
Later on
in the walk you will see what a chalk stream can really produce in terms
of wildlife.
But on the
plus side, you will often see lines of majestically swimming swans along
this stretch and the horse chestnut trees provide good hauls of conkers
for the local children in the Autumn!
