Plant Ecology of the World Issues, Tasks and Methods of Plant Ecology

Plant ecology is an interdisciplinary science that was formed at the intersection of ecology, botany and geography. It studies the growth and development of various types of flora in environmental conditions. Many environmental factors are of great importance for the life of plants. For normal development, trees, shrubs, grasses and other biological forms require the following environmental factors:

  • humidity;
  • light;
  • the soil;
  • air temperature;
  • direction and strength of the wind;
  • relief character.
  • For each species, it is important what plants grow near their native ranges. Many coexist well with various species, but there are some, for example, weeds that harm other crops.

    The influence of the environment on the flora

    Plants are an integral part of the ecosystem. Since they grow from the ground, their life cycles depend on the ecological situation that has developed around. Most of them need water for growth and nutrition, which comes from various sources: reservoirs, groundwater, precipitation. If people grow certain crops, most often they water the plants themselves.

    Basically, all types of flora are drawn to the sun, for normal development they need good lighting, but there are plants that can grow in different conditions. They can be divided into the following groups:

  • those who love the sun are heliophytes;
  • those who love the shadow are Sciophytes;
  • loving the sun, but adapted to the shade scioheliophytes.
  • Life cycles of flora depend on air temperature. They need heat for growth and various processes. Depending on the time of year, there is a change of leaves, flowering, the appearance and ripening of fruits.

    Depending on the weather and climatic conditions, the biodiversity of the flora is determined. If in the Arctic deserts you can find mainly mosses and lichens, then in the humid equatorial forests grows about 3 thousand. tree species and 20 thousand. flowering plants.


    Thus, plants on earth are found in various parts of the world. They are diverse, but their vital activity depends on the environment. Being part of the ecosystem, the flora takes part in the water cycle in nature, is food for animals, birds, insects and people, provides oxygen, strengthens the soil, protecting it from erosion. People should take care of the conservation of plants, because without them all forms of life on the planet will die.
