Examples

  • Here we describe measurements on the structure of the upper canopy and observations on the physiology of overstory leaves.

    Academic text (1992)
  • The much larger size of the overstory species in itself results in a much smaller number of species on a site.

    Academic text (1998)
  • Further shortcomings occur when using vegetation layers classified solely by overstory dominance.

    Academic text (2008)

    Academic text (2016)
  • In our modeling approach, the various silvicultural regeneration methods under evaluation at MOFEP are viewed simply as manipulations that result in varying overstory density that is retained long enough to affect regeneration and whose effect can vary spatially throughout the stand.

Morphology

overstory = story (transparent) = over + story

A direct compound meaning the upper (over) story or level of the forest; the components map clearly onto the sense. [Postprocessing: moved 'over' from base_words to prefix]

Etymology

Overstory comes from over- meaning 'above' and story meaning 'floor' or 'layer', like a two-story house. So the overstory is the 'top floor' of a forest, made by the crowns of the tallest trees.
