The Longest
day has been and gone and so the
evenings are
becoming shorter. With the hot weather many of the plants have
flowered and turned to seed. Hay meadows are ripening and will
be ready to cut this month. A number of silage cuts have already
taken place and there will be some more to go if the weather stays
fine. Fields that have not been cut for silage or hay are being
grazed.
The farmers
have been taking advantage of these last weeks hot weather and
are working hard to bring in their hay and silage. Also the fields
of wheat and barley have in some places turned to a beautiful
golden colour and towards the end of this month we may see that
some corn has been harvested. I have noticed a number of hedgerows
severely cut back this last month. A trim where essential along
roadsides with poor visibility is fine but to really hit hedgerows
at this time of the year not only looks untidy but also destroys
bird nests. Hedge cutting removes food sources in the form of
seeds, berries and nectar and has serious
consequences
not only on birds but mammals and insects too. There are, of course,
always species that take advantage of these devastating effects
on the environment and they are the magpies and foxes that temporarily
gorge themselves on the defenceless chicks that have either been
thrown out of their nest or have already been killed by the flail.
Many of the
birds are busily searching for food to feed their young. Particularly
prominent are Swallows (Hirundo rustica), House Martins (Delichon
urbica) and the Wren (Troglodytes troglodytes). Mammals take advantage
of the summer fruits available during this next month such as
Wild Strawberries (Fragaria vesca) and Raspberries (Rubus idaeus)
which are a particular favourite with Woodmice (Apodemus sylvaticus),
and the omnivorous Fox (Vulpes vulpes) also takes part in this
summer feast
At this time
of year there is an abundance of insects and July is especially
good for Hover flies, Lacewings, Butterflies, Moths and Dragonflies.
Butterfly species that you are likely to see is the Painted Lady,
(Vanessa cardui), Red Admiral, (Vanessa atalanta), and the less
common Clouded Yellow, (Colias crocea). By wetlands, ponds and
streams look out for the dramatic blue and green Emperor Dragonfly
(Anax imperator) or the iridescent emerald green Beautiful Demoiselle
(Agrion virgo) by running streams.

Many insects
are taking advantage of the plentiful supply of nectar that is
available at present. Good places to look for insects are around
flowers that give off a strong odour such as Buddleia (Budleia
davidii) in gardens and on waste ground and Sweet Chestnut (Castanea
sativa) flowers in woodlands.
On the Downs
there are a variety of plant species to look out for and one of
the most prominent is the Bird's-foot Trefoil (Lotus corniculatus).
It has many other names like "Lady's shoes", "
Lady's stockings", "Crow's toes" and "God
Almighty's thumb and finger". The flowers themselves are
shoe-shaped whereas the seedpods resemble bird's claws.
The name
"Trefoil" refers it the three prominent leaves you can
see looking like a three-leaved clover, however on closer inspection
you will see two other small leaves close to the stem. Sometimes
you can find this plant with red or orange streaks on the yellow
flowers and then it is sometimes called "Eggs and Bacon".
Bees and wasps pollinate the flowers of Bird's-foot Trefoil. While
the leaves of this plant, are the food source of the Dingy Skipper
and the Green Hairstreak Caterpillars.

Wild
Liquorice (Astragalus glycphyllos)
|
Another yellow
flower out on the Downs is the Kidney Vetch. It has the other
name of "Lady's fingers" because of the white furry
appearance it gives when fully mature mimicking gloved fingers.
This is also a good nectar source for bees and wasps.
Both these two previous species are members of the pea family
and another much larger member of the pea family is much rarer
on the Downs, is called Wild Liquorice (Astragalus glycphyllos).
This plant
used to be called "Milk Vetch" because it was believed
that if fed to goats, they would produce a better yield of milk.
The botanical name "Glycphallos" means "sweet stem".
This sweet stem's taste does resemble the liquorice plant "Glycirrhiza
glabra" when chewed hence its name.

Wild
Basil
(Clinopodium vulgare)
|
One of the
herbs to look out for on the Downs is the Wild Basil (Clinopodium
vulgare). It attracts numerous insects for its nectar because
of its strong smell. This pleasant smell has long been used to
cover up unpleasant odours. It was included in poses and decorations
for judges during the Middle Ages.
It was used
in warding off diseases by wearing it and was believed to help
against convulsions, jaundice, cramp and a number of other ailments.
Today the cultivated basil is used either on its own or with other
herbs to improve the flavour of many meals.

Hemp-agrimony
(Eupatorium cannabinum)
|
On areas that
have recently been cleared of scrub from downland there is a successful
early pioneering plant called Hemp-agrimony (Eupatorium cannabinum).
The leaves do resemble the hemp plant and originally it was thought
to be in the same family as Agrimony. Its flowers have been gathered
and used to make a red dye for clothing and it is a wonderful
source of nectar for insects.
However, it
can be a nuisance on sites where downland is trying to be restored
because it has a tendency to swamp out less dominant plant species.

Common
Gromwell (Lithospermum officinale)
|
An unusual
flower quite often over looked is the Common Gromwell (Lithospermum
officinale). It has small white flowers and is one of a few plants
to produce grey-white seedpods later in the year. The name "Gromwell"
derives from two French words meaning, "grey millet".
The botanical name "Lithospermum" means "stone
seed" and this refers to the hardness of the seed.
Lastly, a
small tree found on the downs shows itself especially on windy
days by showing the white underside of its leaves as they are
blown about. This tree is known as Whitebeam (Sorbus Aria).
The name derives
from the Saxon "Weiss baum" meaning "white tree".
It is a tough tree that can survive harsh conditions and because
it is decorative with its white leafed undersides and orange berries
later in the year it is grown in gardens and new building developments.
In the past the wood was made into cogs for machines until iron
was used, while the berries were used to make sauces to be cooked
with venison.
Next month
I will talk about what to look out for in the later part of the
summer.
