Shrubland
• Temperature
Hot and dry in summer
Cool and moist in winter
• Precipitation
200 to 1,000 mm of rain per year
• Vegetation
Aromatic herbs (sage,rosemary,thyme,oregano)
Shrubs, acacia, chamise, and grasses
Shrubland
• Location
West costal regions between 30 and 40 degree
North and South latitude
 Shrublands include chaparral, woodland and
savanna
 Plants have adapted to fire caused by the
frequent lightning that occurs in the hot, dry
summers
Shrubland
 Some areas where shrubland are found are
California, Chile, Mexico, areas surrounding
the Mediterranean Sea, and southwest parts
of Africa and Australia
 These regions are usually found surrounding
deserts and grasslands.
shrubland
• Usually gets more rain than
deserts and grasslands but less
than forested areas
• Rain is unpredictable from
month to month
Shrubland
• Very noticeable dry and wet seasons
• Made up of shrubs or short trees
• Not enough rain to support tall trees
• Thrive on steep, rocky slopes
Shrubland
• Usually fairly open so grasses and
other short plants grow between
shrubs
• Plants have adapted to drought-like
conditions
Shrubland
• Small needle-like leaves help conserve water.
• Some have waxy coatings and leaves that
reflect the sunlight.
• Some develop fire-resistant adaptations to
survive frequent fires that occur in dry season.
Animal
Silver-Horned Oryx Lesser Kudu
Animal
• Topi (Tsessebe)
•
a medium-sized species of antelope
•
Topi eat grass and only grass.
•
If they have access to fresh green
grasses, Topi can go without water
for long stretches of time, taking to
the shade of the trees during the hot
daytime hours.
•
Topi are considered one of the most
social mammal species of the
Serengeti.
Animal
• Chousingha
– Four-horned antelope
• Considered at high risk
for extinction
• A group is a herd or a
cluster
Animal
• Walia Ibex
– Critically endangered
– Species of wild goat
found only in mountains
of Northern Ethopia
– Only known predator of
the adult Walia is the
hyena
Animal
• Nyala
• The focus of a habitat
specific conservation
program
• The cessation of the
program would result in
the Nyala being placed on
the threatened list within
5 years
Animal
• Goral—so rare that it is listed as a
nearly threatened species by the
International Union for the Conservation
of Nature

Gorals don’t make easy targets for human
hunters.
They can race up sheer rock-strewn
slopes as easily as a cow walks across a
meadow.
Gorals coloration of a muted grey-brown
helps them blend in with their
surroundings.
Unless they move, gorals are particularly
hard to spot.
Gorals can easily exist up to 9800 feet
(3000 meters) above sea level.
The oxygen is too thin for most people
except the native peoples of the
Himalayas.
Plants
• Curara
– (Acacia tetragonophylla)
• moderately palatable
and a valued protein
source in most habitats.
• All classes of stock use
the foliage. Silver-green
curara plants in hill
situations and on skelet
Plants
• Bardie bush
– (Acacia victoriae)
• readily browsed in dry
periods and the flowers and
pods are sometimes
preferentially grazed.
• Young plants may be very
heavily grazed when stock
numbers are high
Plants
• Sage
– (Cratystylis
subspinescens)
• not as palatable as the
saltbushes it grows
with, but where stock
waters are saline, sage
is preferred over
saltbush.
•
Plants
• Frankenias
• (Frankenia spp.)
• Frankenias are only
eaten by livestock when
the drinking water has
low amounts of salt
Plants
• Sago
• Maireana pyramidata)
• grazed, though it is not a
highly preferred forage
plant when pasture is in
good to fair condition
• it is a valuable
component of the pasture
and withstands heavy
grazing.
