Ecological succession

From Simple English Wikipedia, the free encyclopedia
After a forest fire: ecology changes after 1 year (left photo) and after 2 years (right photo)

Ecological succession, is how a specific ecology changes after a disturbance like a fire.[1] In long-term studies, there is a species succession process in the way forests develop.[2]

Notable ecologists[change | change source]

Several scientists are prominent in the history of this theory:

  • Adolphe Dureau de la Malle was the first to use the word succession. He wrote about the process of re-growth after trees in a forest had been cut down.
  • Henry David Thoreau described succession in an Oak-Pine forest in "The Succession of Forest Trees" in the year 1859.
  • Henry Chandler Cowles developed a formal concept of plant-growth succession. Henry's work was based on studies of sand dunes in Danish by Eugen Warming. Cowles proposed the term sere. This is a repeat of changes which are shown in specific environmental circumstances.[3]
  • Frederic Clements proposed a theory that seres were highly predictable.[3]
  • Henry Gleason proposed that chance factors were very important, even in highly predicable sere areas.[3]
