Knowing Plant Ecology is fundamental to Knowing How to Grow and Manage Plants

This makes it very important for anyone working in agriculture, horticulture or enviromental management! You may choose to study this to fill in a "gap" in your education; to compliment something you already work at, or to improve your prospects in business or carrer, in the future.

  • Learn how plants interact with each other and the environment they live in
  • Develop a deeper undersatanding of plants for working in science, biology, the environment, agriculture, gardening, landscaping, organic farming, permaculture and herbal medicine
  • Self paced 100 hour course.
The term "ecology” was first introduced in 1869 by a German biologist named Ernst Haeckel. The term was derived from the Greek "oikos", which means household or home, and “logos”, which means word or study. Ecology, then, is the study of plants and animals in relation to their home, or environment. The study of ecology was further advanced by Charles Darwin, with his theory of evolution and Alexander von Humboldt, who made extensive explorations in the Orinoco and Amazon River regions in South America in the nineteenth century.

What are the Different Types of Plant Communities?

There are two main types of plant communities.

  • Open plant communities consist of open canopies with sparse vegetation and usually one or two canopy layers.
  • Closed communities include more dense vegetation with a closed canopy. Closed communities may consist of rain forest plants and include larger leafed species.

In contrast with closed communities, open communities develop where there is shortage of resources, like African savannas, North American prairies and Asian steppes, all suffering from shortage of moisture for at least several months a year, or open forests on rocky grounds lacking enough soil to grow on.

Habitat Types

The earth can be divided up into different types of areas with shared characteristics. The simplest division is that into areas covered by water and areas covered by dry land. This division is based upon simple physical characteristics. There are many other ways of dividing up regions which are far more complex; based upon not just physical characteristics but also the living things that inhabit an area. Regions of the world can be differentiated according to environmental conditions, topography and dominant plant and animal species. For example, the use of such criteria allows us to see that tropical lowland rainforest is very different to arctic tundra.

This course helps you understand all these different ecosystems and how plants fit into each.
