Life
Dependency by Alan Marshall
Members of our group are mostly
keen birdwatchers. However, some, during the quiet months of summer
when the bird-song has faltered and finally ceased, turn to other
interests of Natural History. Dragonflies and Damselflies sometimes
hold their interests, and some turn to other insect life such as
butterflies and moths. I wondered the other day why so few turn to
truly wild plant life.
There is something fascinating
about a truly wild plant. It is not fed or un-naturally watered, and
the ground is not specially prepared. It arrives usually as a seed
and either grows or lies dormant, sometimes for years. Look how the
poppy seeds of Flanders were very much disturbed and how they covered
the ground afterwards.
Botany is a huge and fully
absorbing subject. It is not just the attractive look of the flower
or its scent that excites! First, as with birds, there is the problem
of identification with probably more difficulties than with
ornithology. Just when you think you've mastered the simpler common
species, one turns up that you think you ought to know but cannot
quite place.
After finding out which species of
plant you're looking at, there comes the question of why it should be
there. As with the birds, the environment is important. Woodland,
seashores, meadows, or Tophill lagoons are all different habitats and
so are the plants that grow there. However, some plants seem to
manage to live almost anywhere, but even they have preferences.
Think of the many foot-pathways in
this country. There, being trampled by many feet, grows a plant which
gives off a wonderful scent of Pineapples. Few other plants can
survive for long where this plant grows successfully for years. In
the winter the main roads around Hull have been de-iced with salt and
the traffic has sprayed it onto the verges. Saltmarsh plants have
been seen flowering in this new habitat. Alter the habitat and the
plants growing there will change.
In this world of global warming the
natural world is giving the first indications of forthcoming climatic
upsets. Hence there is a need to record what we see. This is a task
that can become ever more enjoyable by actually doing it. There are
many aspects of plant life that are not very well recorded. For
example, would anyone or a group feel competent to regularly make a
list of all the mosses, and/or fungi of Tophill Low and the area
around it? The East Yorkshire Botany Club made a list of the plants
and trees some years ago. Besides the flowering plants the list
included such difficult species as the grasses, sedges and rushes and
we have endeavored to keep that record up to date every year.
I have also noted some changes to
the Tophill site such as the slow disappearance of species in the
"O" Reservoir wood and the remarkable increase in such
species as the Nodding Bur Marigold and Water Violet. I have been
delighted to find plants here that I have not seen elsewhere,
probably because I visit this site more frequently than other places.
All living creatures could not
exist without plants, hence my title. It is an obvious statement for
such creatures as seed-eating birds, but they in turn are preyed upon
by raptors. We eat some plants, others are eaten by cattle. It is all
part of the worldly food cycle; without it we would not survive. So
plants are important. They are very interesting too and
humanity has used them for many purposes as well as for food. They
have been used for fibres and dyes, for medicines (still being
discovered in plants), for charms, and, dare I write it, for poisons.
These latter named plants should not be up-rooted because they are
harmful if eaten. Keep the children off them. They may be used in the
future and possibly have some useful chemical in them waiting to be
discovered. In Tophill Low East pond we have a rush that was the only
sort that could be used for making chair seats.
Hemp (not at Tophill) was used also
for rope making and I found a Cannabis plant growing on the old
Victoria Dock before it was built up with houses. Dr. Eva Crackles
suggested it might have come from the rope works that was there. It
is illegal to grow it anywhere now.
For years I made whistles for my
children and eventually my grand-children too. These were from Cow
Parsley stems. I did this without realising how similar it was to
Hemlock, the poisonous plant used by ancient Greeks in judicial
executions. It grows in great quantity at Tophill Low. In the same
family, umbels, can be found even more deadly poisons but also plants
like the Wild Carrot, the precursor of our modern carrot. Fennel and
Wild Parsnip also belong to this family and have been cultivated over
the years for culinary purposes. Another kitchen umbel is Chervill, a
popular herb but beware of using the wild one, Rough Chervil. Its old
scientific name gives the clue to what it can do if it is used in the
kitchen. It was called Chaerophyllum temulentum,
and the specific name indicated that it would "give you the
shakes", affecting the nervous system if eaten.
There are many other uses that
plants have been put to. Early insect repellants, for example, not
only for human use but also for oxen at work in the fields. Another interesting facet to
inquire into is how plant life has been used for charms and magic. We
still retain some of the ancient rites at Christmas time with Holly
and of course Mistletoe. Plants used to be hung round the byre to
keep away evil spirits. St. John's Wort was used in the 16th Century
to raise ghosts. Near the "O" reservoir is an unusual St.
John's Wort. When it flowers in late June to September have a look
under the petals and you will see lines and not the usual dark dots,
but don't expect too much in the ghost-busting department!
So I hope that with me, bird
watchers will look at plants with the same enthusiasm as concerning
our feathered friends.
