117A Plants For A Future Quiz
- Mar 8, 2002Thank you, I will be interested to see how much I know and learn more. Caat
The loveliest of faces are to be seen by moonlight, when one sees half
with the eye and half with the fancy.
We've been busy preparing some quizzes to go on the web-site
and fit in with our educational program.
I though the people on the mailing list might be interested
in having a go.
Let us know if you like the idea. I've two more quiz sheets
and I'll probably post them in a couple of weeks time.
All the best
PFAF Intro Quiz
There are many thousands of species of edible plants throughout the
world, yet surprisingly few are grown for food. How many species provide
the vast majority (more than 90%) of our food?
Less than 20
There are about 7,400 species in the PFAF database of plants that can
be grown outdoors in the Temperate zone.
Of these, how many are edible?
More than 5,000
How many have medicinal uses?
More than 5,000
How many have other uses?
4,500 - 5,000
Conventionally, food crops are usually grown as single crops in straight
rows in large fields (monoculture). PFAF advocate an entirely different
method of growing lots of different species together in an integrated
system that mimics the way plants grow in nature. Tick which of the
following statements are true.
Unlike conventional systems, the PFAF system does not need
any input of fertilizers.
The PFAF system is beneficial for our native flora and fauna.
There are more birds per acre in towns than in the countryside
nowadays because conventional systems have destroyed wildlife
habitats and food sources.
The natural system most commonly promoted by PFAF is the woodland
garden. In this system it is possible to grow a very wide diversity
of plants together, using taller trees to form the canopy with smaller
trees and shrubs growing beneath them. Climbing plants can make
their way into these trees and shrubs whilst perennial plants, bulbs
etc. can be grow in the shade and in the sunnier edges of the woodland.
Which of the following statements about a woodland garden are correct?
A woodland garden is potentially the most productive system
for growing foods, medicines and many other useful commodities.
Farms of the future will be large woodland gardens.
We hear a lot about the destruction of the rainforests and the impact
on the global environment, but we do not always realise the extent
of deforestation that has taken place in the temperate zone.
How much of Britain was covered in forests before humans starting
More than 90%
There are many other natural or semi-natural habitats in addition
to a woodland. Which of the following habitats would not be suitable
for growing useful plants?
A meadow A lawn The seashore
A pond or lake Marshy land The ocean
A river A moorland Mountain slopes
The botanical (or Latin) name of a plant is the best means of ensuring
the correct identification of plants. Common names can be applied to
different plants in different places - thus in England the plant
called a harebell (Campanula species) is a plant with edible leaves
and flowers. In Scotland the harebell (Hyacynthoides non-scriptus)
is a poisonous plant with a bulb that can be used as a paper glue.
Latin names, however, can be informative. See if you know the meanings
of the following botanical names:-
Sylvestris A woodland plant Growing in fields A marshland plant
Angustifolia Large leaves Large fruit Narrow leaves
Macrocarpa Small fruit Fat stems Large fruit
Maritima Growing by the sea Growing on rocks Growing in the spring
How would you decide which plants were safe to eat if you were
stranded in a strange place with no food and were desperately hungry,
but with no knowledge as to which of the plants around you were
edible? The following list includes the guidelines from survival
guides. Please list them in order, omitting those that you feel
are irrelevant or misleading.
Observe if any other creatures are eating it - if they can
then it is probably alright for you.
Crush a small leaf and rub it on the sensitive skin on your
wrist and then wait an hour to see if a rash develops.
Chew a small part of the plant then spit it out and wait
an hour to see what happens.
p.s. Can I take this opportunity to encourage to you to join our
friends of Plants For A Future membership scheme. Membership is only
£10 a year (£15 overseas) and we are trying to recruit 1000 friends
in the coming year. If we can reach this target then we will be
able to secure the land for our demonstration gardens and visitors
centre in Devon which could become a shining example of woodland
gardening, sustainability, and the use of perennial plants.
