overstory

A Garry oak overstory is often, but not always, present.

Some forests are characterized by an overstory of emergent trees.

Although the stand overstory is generally removed in one harvest under clearcutting, that was not the approach here.

It must be in the overstory to thrive.

Community biomass accumulation resulted from increases in the overstory.

The forest overstory is a relatively closed stand of mixed bottomland hardwoods.

After three field growing seasons, the overstory was removed on one-half of the underplanted plots.

The relatively slow height growth of water hickory requires that it have near freedom from competition to establish itself in the overstory.

They have a eucalyptus overstory (10 to 30 metres) with the understory also being hard-leaved.

Structurally, these forests are rather simple, generally consisting of two layers: an overstory and understory.

The overstory includes several types of oak and Carya ovata var.

The loblolly pine overstory was the dominant factor influencing the long-term development of the understory.

The removal of Douglas-fir overstory has strong effects on the plant community, but the specific patterns depend on the species and site involved.

The spread of dwarf mistletoes in forest stands is greatest from the overstory to the understory, due to gravity.

This resulted in a massive forest fire that left large swaths of the forest, including the overstory, severely burned.

Changing the landscape configuration and composition of the forest overstory may have effects on this important component of the native biodiversity.

The overstory includes miro, rimu and mountain totara.

In areas harvested under the shelterwood system, 20-30% of the overstory is left to protect the immature spruce from windthrow.

Therefore, light transmission through the overstory influenced the structure and function of understory plants more than their diversity and composition.

In the old aspen stands, there was more light transmission through the overstory, which led to increased understory cover and light interception at that level.

Six Acer species were recorded; they occurred primarily in the subdominant overstory and the understory of both ecosystems.

The overstory facilitated pine seedling survival.

This shrub is a pioneer species that increases after disturbance and decreases as the overstory grows back and shades it out.

These shifts in density were unrelated to changes in the density of the overstory or of other shrubs.

Naturalist William Beebe documented pairs of crested argus flying to and from the overstory.
