clearstory

(both: klĭr`stōr'ē, –stôr'ē), a part of a building whose walls rise higher than the roofs of adjoining parts of the structure. Pierced by windows, it is chiefly a device for obtaining extra light. It had an early use in certain Egyptian temples, as at Karnak, and was used later in the great halls of Roman basilicas. It became a characteristic element of medieval churches, receiving its fullest development in churches of the Gothic period.

Clerestory

An upper story or row of windows rising above the adjoining parts of the building, designed as a means of admitting increased light into the inner space of the building.

We highlight four clear parallels between the decline of northern American forests and Australian eucalypt forests in response to the long absence of fire: (1) the increased development of midstorey vegetation, the decline of fire tolerant tree species and the dominance of shade tolerant species; (2) increased total stand water use and increased mortality due to drought of fire tolerant/shade intolerant overstorey trees; (3) altered soil microclimate and microbial dynamics and; (4) increased occurrence and risk of wildfire in xeric P.
To redress this balance, Gordon and Reddell aimed to rehabilitate the Ranger site from the overstorey down, by putting back the large canopy trees and allowing the understorey to re-establish itself.
Although the undisturbed native forest is not particularly diverse, rehabilitated areas typically are diverse, with many understorey and overstorey species sown.
