Britain’s countryside
Save it with flowers
We are Plantlife
Plantlife is the organisation that is speaking up for
our wild flowers and plants. From the open spaces of
our nature reserves to the corridors of Westminster,
we’re here to raise their profile, to celebrate their
beauty, and to protect their future.
Wild flowers and plants play a fundamental role for
wildlife, and their colour and character light up our
landscapes. But without our help, this priceless
natural heritage is in danger of being lost.
Join us in enjoying the very best that nature has to
offer. Britain’s countryside. Save it with flowers.

Breckland Plants
ID guide
BRECKLAND PLANT SPECIES ID GUIDE
The plants of Breckland
The unique heaths and dunes of Breckland are home to
many plants of outstanding importance. These plants
require poor soils and some disturbance to flourish.
With the changes to Breckland habitats over the last
100 years, many plant species are on the edge of survival.
What is Plantlife
doing to help?
Over the period 2010 to 2013,
Plantlife, with the aid of a
substantial grant from GrantScape,
has been maintaining and restoring
existing and lost populations of
some of the rarer species.
Conservation action has involved
increasing grazing and causing
ground disturbance which is vital for
species survival. Guidance will also
be given to other organisations who
manage some of Brecklands
threatened plant populations.

How can you help?
We need volunteers to help monitor
species in the conservation areas
and other important plant areas in
Breckland so that we can assess the
progress of these species and be
confident that their populations are
being sustained or are increasing.

How do you monitor the plants?
Identifying plants
The methodology used in this project will
be kept as simple as possible.
The plant species in this guide
have been labelled using a traffic
light system where
Frequently, plants in the Brecks are
much smaller than those of the
same species that occur elsewhere.
● green indicates easy to identify
Most of the terms used to describe
the parts of the plants and in the
descriptions are explained or
illustrated, but the following diagram
should help with the general
botanical names for parts of a
flowering plant and a grass.
●
●
Presence / Absence As many of the
species are rare, this will mostly
involve searching for species within
the survey area, and noting if they are
present or absent.
Counts In some cases where a few
species exist we may ask you to do a
quick count of these species.
Estimates Where larger populations
exist then an estimate of numbers
and/or abundance may be needed.
All these methods will be covered during
our Brecks volunteer training days and
more information on monitoring is
available at

Where do you survey?

similar species
Survey sites are scattered across the
Brecks so we hope that you will be able to
choose one that is close to you. A list will
be put onto the above website.
● red indicates the most difficult
to identify, often because they
are extremely small and hard
to find
What plants are you
looking for?

The geology of Breckland
Pingos
The area is defined by the underlying
geology that comprises a low chalk plateau
laid down in the late Cretaceous period 65100 million years ago when the whole area
was a shallow tropical sea. The end of the
Cretaceous era saw the chalky tropical sea
recede leaving behind the chalk.
The tundra conditions of the time also
created strange domed structures
where ground water beneath the
surface froze and expanded pushing up
the surface, sometimes exposing the
ice. As the ice thawed, so the dome
collapsed in on itself leaving a
depression with a raised rim of sand
around it. These depressions are known
as pingos, and many are now filled with
water. Good examples of pingo systems
can be found at Foulden, Thompson
and East Harling Commons.
Around 400,000 years ago the Anglian ice
sheet covered the area and left behind a
layer of sandy glacial drift which was very
thin in places. The last glacial period,
between 12,000-100,000 years ago, was a
period of freeze/thaw with tundra like
conditions which caused the wind blown
sandy deposits to develop alternate bands
of acid sands and alkaline chalk. This
leading to the characteristic striped soils
that can still be detected in Breckland, for
example on Thetford Heath and at Grimes
Graves.
The climate of Breckland
East Anglia is the driest region in the
British Isles, and Breckland is the driest
area within East Anglia, having a semicontinental climate characterised by low
rainfall, higher summer and lower winter
temperatures than the average in Britain,
with late spring frosts being common.

Rabbits were introduced
by the Normans and bred
in warrens for their
meat and fur.
Their contribution to the
landscape is recognised in
the frequent use of
‘warren’ at the end of
names of heaths.
Typical
Breckland habitats
Mobile sand dunes
The early forest covering Breckland was
cleared by settlers exposing light sandy
soils to the wind. This created a large area
of inland sand dunes. Until recently most
of these were moving dune systems.
Where the sand dunes do still exist, for
example at Wangford Warren, Suffolk, they
have been colonised by sand sedge
Carex aranaria.
The mobility of the sand dunes and the
disturbance caused to the poor soil are
responsible for the characteristic flora of
the Brecks. Much of this is now endangered
8
Dry heaths and grassland
Due to the geology, Breck heaths and
grasslands have an underlying mosaic of
calcareous and acidic soils. These
correspond with a mosaic of plant species
suited to the differing areas: hence it is
possible to find acid loving plants in the
same area as chalk lovers. Disturbance and
short grazing, traditionally provided by
sheep and rabbits, prevents invasion by
more robust species.
Loss of traditional Breckland heath in the
last century has been rapid. There is now
only about 7,000 hectares of dry heath (27
square miles) compared to 29,000 (112
square miles) in 1900. This is partly due to
large areas of this poor quality land being
converted to conifer plantations e.g. Thetford
Forest, now the largest area of lowland forest
in Britain covering 20,000 hectares (77
square miles). Other areas of heath were
converted to arable land, grazing of sheep
has declined and after World War II the
warrens were abandoned with rabbits being
almost wiped out by myxemotosis in 1954.
Rabbit populations have never fully
recovered, and, combined with the loss of
sheep grazing and management, such as
the collecting of bracken and heather for
animal bedding, large areas of remaining
heath have become more densely vegetated,
crowding out the plants that preferred the
disturbed, tightly grazed land. Traditional
Breck heaths exist now only as fragments
scattered across Breckland. Under these
conditions it is hard for some plant species
with specific requirements to flourish.

Why is the Breckland unique?
Breckland, or ‘the Brecks’ is a c.400 square
mile area that straddles the western end of
the county boundary between Norfolk and
Suffolk (see map below). The geology and
climate of the Brecks combine to give the
dry soils and dry climate which make the
area unique within the British Isles. Many
plants found here are found nowhere else
in the UK, making it one of Plantlife’s
Important Plant Areas (IPAs).

www.plantlife.org.uk/wild_plants/impor
tant_plant_areas
Breckland is
thought to come
from the old
Norwegian word
braec which meant
“land newly
broken for
settlement”.
Because of the
poor soil, the land
would be
cultivated for a
few years and
then left to revert
to heath.

that it has both male and female flowers on
the same stem but in different spikelets.
The single male spikelet is born at the top of
the stem and it is cylindrical, but narrows to
a point. The 1-3 female spikelets are below
the male and are more rounded and blunt.
The appearance of each is that they are dark
purple-brown but each glume (the cover of
the individual florets that make up the
spikelet) has a broad and pale top edge.
Habitat: dry, calcareous and short
grasslands.
Status: vulnerable
cf: Spring Sedge Carex caryophyllea
The stem has sharp angles, and the leaves
are a shiny bright green. The male spikelet
is red-brown and club shaped, the females
also red-brown and are more rounded, each
glume has a projecting green rib down its
length. Much more common than
