. d) The frequent outbreak of bush fires destroys  the  grass retarding  its  regeneration√√

the increasing human population is  encroaching  into the   grasslands replacing them  with settlement and cultivated land√√

pests such as  army worms /locust destroy the grass and the vegetation degenerations into a semi- desert type√√

wild and  domestic  animals overgraze  and cause stunted growth of grass√√           

3.         a i) -Natural vegetation is the plant cover that exists in an area without the interference

                    of external  modifying influence especially people and their animals

-Forest species are generally few and large tracts of forests can consist of only one or

  two species of tree(occurs in pure stands)

-Most of the species are softwoods which mature faster

-Most species are evergreen but a few she their leaves eg fir,pine and larch.

– Trees have a widely spread shallow root  system for utilizing moisture from the top soil

  since  most of the  time subsoil is permafrosted         

       c)    -some plants have thick leaves and banks for storing water.                                              

-some plants produce seeds  which lie dormant for along time and germinates when the

 rain falls

-some plants sheds leaves  during the onset of the dry season to reduce loss of water

through  transpiration

-trees in the region have long rots to tap water from the water table below

-tress in the region are umbrella shaped to provide shade that reduces the rate of    

 evaporation  around the stem

. d)    – Frequent outbreak of bush fires destroy grass and retard its regeneration             

-frequent drought destroy the grass and so the vegetation degeneration into a semi-

 desert type.

-overgrazing of domestic and wild animals causes stunted growth of grasses

-pests such as army worms and locusts destroy the grass, thus reducing the rate of


4.         a )            X –  Veldt

                     Z –  Stepper

         b) – Some plants have a short life-cycle this enables them to survive during the short

            period of  wetness.                                                                                                                                    

– Most are salt tolerant (Halophytes) to enable them survive in the saline soils of the


– Most plants have succulent leaves that store water to enable them survive the long

  drought  period.

–  Some plants have fibrous stems which they use as breathing surface.

– Most have deep roots to reach the deeper water table.

– Some have spines/thorns which protect them from browsing animals.

– Some are drought resistant & deciduous which enable them shed their leaves during    

 dry  season.

5.         a i) L is savanna (park savanna)                                                                                      

       ii) – The vegetation is tropical rainforest/ equatorial forest                                               

– The forest consist of mixed variety of tree species

– The trees shed their leaves at different times of the year/ ever green

– The trees are tall with large trunks

– The trees have broad; leaves/ drip tipped leaves

– The trees take long to mature

– The tree species are mainly hard woods

– The forest trees grow close together

– The forest has numerous lianas/ climbing plants/ epiphytes

– Some plants have underground bulbs that remain dormant awaiting short the rains     

             c i) – The temperatures are too low to support vegetation                                                    

     – The surface is mainly bare rock, so no soil has formed to support vegetation

    – Water is always  in a frozen state, i.e. snow, so it is not available to plants

           ii) – Vegetation is of aesthetic value as it adds beauty to the landscape                              

– Vegetation binds soil together using its roots. Its aerial parts reduce the impact of raindrops  on the soil. In this way, it protects the soil against erosion

– Plant remains decay to become humus. This improves the fertility of the soil

– Some plants are of medicinal value to people. Their leaves, barks or roots are extracted and  prepared into medicines, both traditional and modern

– Some trees are used in the manufacture of paper while others are used for the manufacture   of plywood, veneer or production of timber

– Some plants are eaten by people e.g. bamboo shoots

ii) – Grazing the plenty tall and short grasses are used for  grazing livestock and  wild               


– Reduces  soil erosion-savanna  vegetation act  as  soil cover  hence  reduces soil


– Habitat  for  bees  and  wild animals-trees  in savanna are  habitat for  bees which   provide     honey  and  home  foe wild animals e.g. gazelles, giraffe

– Some shrubs   and  herbs  growing in the savanna  are  used as medicine

– Fuel-trees provide  wood fuel and fuel  wood for the people in the tropics

– Gross increases humus  in the  soil making  areas  suitable for cereal farming e.g.

  wheat and maize

d )-  some plants have  long roots to enable them tap water far deep the  ground√√        

– some pants  have shallow root system  which enables them to take  moisture from the

  soil layers

– some plants have  sunken  stomata  and waxy leaves  to  reduce rate of 


– some  plants have succulent stems  to  allow  them store water√√

– some plants are short lived i.e.  Complete their  cycle  within the short wet period√√

– some  plants  e.g.  tubers and  corns  remain dormant during dry spell until wet period


7.         a i) S- Steppes                                                                                                                    

      T- Pampas

     Y – Savanna

    Z – Downs

      ii ) – the vegetation consists of a continuous cover of grass, the grass is tufted           

– The grass is interspersed/mixed with bulbous/leguminous plants/shrubs

– The grass is nutritious. Grass is tall in moist area

     – The grass is short and tough in drier areas about 15-30cm in height

      – The grass is green in spring/brownish yellowish and strow like in summer/Grass

        withers in autumn and die in winter/rare grass sprouts in spring/Trees are only found

       along rivers/ rive rine trees/ trees found in hollows where rain water collects.

  – common grass varieties are gamma graze/buffalo grass

 – In drier, areas, the short grasses form bunches separated by bare soil

       – Tress found along river courses are temperate trees like popler, willo adler

8.         a i) – It is a plant cover existing naturally in a place but has been interfered with by man

               ii)                –     Altitude                                                                                                  

  • Aspect
  • Soil
  • Climate/ temperature/ rainfall
  • Man’s activities

             b) i)   – Savanna vegetation                                                                                                        

  • Rainforest
  • Bamboo forests
  • Health and moorland

             ii)   – prairies                                                                                                            

  • steppes
  • downs
  • veld

  iii)   – some have thick/fleshy/succulent  leaves /barks                                                           

  • some have long tap  roots
  • some  have no  leaves /have  thin/spiky/waxy/needle like leaves
  • some plants have  thick/hard  barks
  • some  plants have  thorns
  • some  plants  are  stunted/dwarf like
  • shrubs are common
  • some plants spout  during wet seasons (short  time)

9.         a)    – fire-often ,large  areas of  forests are destroyed  by accidental  and sometimes

                    intended  fire. such forests takes long  to recover                                                          

  • diseases   causes by pests and parasites attack  mainly  the planted  forests causing many trees  to die
  • human activity  /settlement /charcoal burning/logging have  destroyed  many  forests areas of which are transformed in to farms and  grasslands
  • over-exploitation leads  to depletion of certain tree  species such as Meru oak, camphor and Elgon teak. these trees take long  to mature
  • government policy of  degazetting  of some forests  made  people free to clear  many  forested areas
  • prolonged droughts  lead  to degeneration  of forests some of which  take long to recover

(b) Rain forest have closely set trees with these districts canopies.                          

  • This crowns and closeness of the trees form a dense shade for the lower layer which makes  arvesting cumbersome.
    • Most trees are tall, and have huge trunks. This makes them cumbersome to be harvested and most of them are heavy to be transported.

High amount of rainfall.

  • This forest lies within the equatorial climatic region where high amount of rainfall is

received throughout the year.

  • This means that harvesting of trees can not take place throughout the year because of the very dump condition in the forest and general disturbance caused too much rains.

Tree species are not found in pure stands

  • Rainforest do not have pure stand and this become a problem if one need to harvest only one species meaning moving from one part of the forest to another as one harvest.

Majority of the species are hardwood.

–           These species are hard to be cut and also heavy to be transported
