What Types of Natural Vegetation Make Up The
Atlantic

• Natural vegetation refers to plants that grow
  without any human interference
• Different types of natural vegetation grow in
  response to different climatic and soil
  conditions
• The Types of natural vegetation that make up the
  Atlantic are the Boreal and Taiga Forest, and
  the Mixed Forest

Boreal and Taiga Forest

• The Boreal and Taiga Forest is separated from the
  Tundra by a tree line.
• It is the largest natural vegetation region in
  Canada.
• Coniferous trees such as evergreens are commonly
  found throughout the Boreal and Taiga Forest
  because there is a longer growing season and more
  precipitation than in the Tundra.
• It also contains some deciduous trees which are
  able to withstand the harsh winter conditions.

Boreal and Taiga Forest Contd

• Coniferous trees as well as the evergreens lose
  some needles throughout the year but they are
  never bare.
• Since they dont drop a lot of needles the humus
  layer beneath them is quite shallow.
• This gives the topsoil a grey color.
• Also, because the needles are acidic this makes
  the soil acidic.

5
Mixed Forest

• The mixed forest is south of the boreal forest in
  eastern Canada.
• It contains a mix of coniferous and deciduous
  trees such as spruce, pine, oak, birch, hemlock
  and cedar.
• It has provided an excellent source of lumber for
  the lumbering industry.
• The humus layer created by the leaves makes a
  lush top soil which is rich in minerals.

Mixed Forest Contd

• This forest is a transition zone between the
  deciduous forest to the south and the boreal
  forest to the north.
• Both the coniferous and the deciduous trees are
  able to survive warm summers as well as cool
  winters.
• Humus holds water, and therefore fewer soluble
  minerals are removed from the topsoil in the
  mixed forest than in the boreal forest.
• Soils in the mixed forest regions are suitable
  for farming
