Types of Trees/Vegetation and Types of Grasslands

Distiction between Hardwood and Softwoods:

The distinction is to do with plant reproduction. All trees reproduce by producing seeds.

1. Hardwood trees are angiosperms, plants that produce seeds with some sort of covering. This might be a fruit or a hard shell, such as an acorn from the Oak.
Softwoods are gymnosperms. They let seeds fall to the ground with no covering. Pine trees, which grow seeds in hard cones.

2. Hardwood/angiosperm trees lose their leaves during cold weather while Softwoods/gymnosperm trees keep their leaves all year round.

3.The density (or mass) of the wood is irrelevant.

Hardwood Trees(Angiosperms):
They are used for making furnitures,Transport and Construction Materials. They are Rosewood, Ebony, Mahagony, Sal, Teak, Neem, Shisham, Oak, Eucalyptus,Ash,Beech.

Softwood Trees(Gymnosperms):They are used for making Pulp which is used for Manufacturing Paper and Newspapers,Match Boxes and Packing Boxes.They are Chir, Pine, Cedar


Types of Trees in different Vegetations:

  1. Tropical Evergreen contains Hardwood trees mostly.
  2. Tropical Deciduos contains Hardwood Tree which shed their leaves(Sal, Teak, Neem, Shisham)
  3. Temperate Evergreen contain both hardwood and softwood(Oak and Eucalyptus+Pine)
  4. Temperate Deciduous  contain both hardwood mostly(oak, ash ,beech)
  5. Mediteranian contains orchards(Orange, figs, apples, olives, grapes)
  6. Coniferous Forests contains Softwood Trees such as Chir, Pine,Cedar.


Types of Grasslands:

Tropical Grasslands

  • Savanna--East Africa
  • Campos-Brazil
  • Llanos-Venezuela
Temperate Grasslands

  • Pampas -Argentina
  • Prairies-Nort America
  • Velds-South Africa
  • Steppes-Central Asia
