For my presentation, I’m going to summarise what I’ve found out about efforts to save one plant species... the juniper bush. It once flourished in Britain and throughout the world’s temperate zones, but over the last few decades has declined considerably. Before I go on to explain the steps being taken to save it in England, let me start by looking at some background information and why the juniper has been so important in cultural as well as ecological terms, historically and in the present day.
Firstly, I want to emphasise the fact that juniper is a very ancient plant. It has been discovered that
it was actually amongst the first species of plants to establish itself in Britain in the period following the most recent Ice Age.
And, as I say, it has a much-valued place in British culture. It was used widely as a fuel during the Middle Ages because, when burnt,
the smoke given off is all but invisible
and so any illicit activities involving fire could go on without being detected, for example, cooking game hunted illegally. It also has valuable medicinal properties. Particularly during large epidemics,
oils were extracted from the juniper wood and sprayed in the air to try to prevent the spread of infection in hospital wards.
And these days, perhaps its most well-known use is in cuisine... cooking,
where its berries are a much-valued ingredient, used to flavour a variety of meat dishes and also drinks.
Turning now to ecological issues, juniper bushes play an important role in supporting other living things.
If juniper bushes are wiped out, this would radically affect many different insects and also fungus species. We simply cannot afford to let this species die out.
So, why is the juniper plant declining at such a rapid rate? Well, a survey conducted in the north and west of Britain in two thousand and four to five showed that a major problem is the fact that in present-day populations,
ratios between the sexes are unbalanced
and without a proper mix of male and female, bushes don’t get pollinated. Also, the survey found that in a lot of these populations, the plants are the same age, so this means that bushes grow old and start to die at similar times...
1eading to swift extinction of whole populations.
Now, the charity Plantlife is trying to do something to halt the decline in juniper species. It’s currently trying out two new major salvage techniques,
this time focusing on lowland regions of England.
The first thing it’s trying is to
provide shelters for the seedlings
in areas where juniper populations are fairly well established. These, of course, are designed to help protect the plants at their most vulnerable stage. A further measure is that in areas where colonies have all but died out,
numbers are being bolstered by the planting of cuttings
which have been taken from healthy bushes elsewhere.
Now, I hope I’ve given a clear picture of the problems facing this culturally and ecologically valuable plant and of the measures being taken by Plantlife to tackle them. If anyone has any questions, I’d be happy to...
