<br /> This booklet lists green ash as the most widely distributed of the ashes
<br /> in North Carolina, commonly sighted along rivers and streams and on iow
<br /> grounds. Red maple is reportedly distributed throughout the state, with
<br /> various sub-species occuring in various habitats. Sweetgum, a common
<br /> species in the piedmont and coastal plain, occurs on rich river b6tt0m$
<br /> and in swamps subject to frequent overflow, as well as on drier uplands.
<br /> Sycamore is abundant throughout the state along streams and on rich
<br /> bottomlands. BoXelder, which is not considered a common species, ·occurs
<br /> in the piedmont and coastal plain of North Carolina.

<br /> six bott0mland tree species. Ecology 39(2):371-373.
<br />
<br /> This article discusses the effects of complete inundation of seedlings
<br /> of six bottomland hardwood tree species--cottonwood, willow, sweetgum,
<br /> green ash, boxel~er, and silver map!e--for periods of 2, 4, 8, 16, and
<br /> 32 days. Except for silver maple, which was grown from Seed' in a
<br /> greenhouse, current-year seedlings were collected in the field,
<br /> transplanted into two-and-a-half inch pots, and allowed to grow for 3
<br /> weeks before inundation. The seedlings were about 3 inches high when
<br /> the test began, and all species except silver maple appeared healthy at
<br /> the start. I~undation was in tanks placed outdoors in an area exposed
<br /> to sunlight until 2:00 p.m.; WAter temperatures during the day ranged
<br /> from 88-93°F. The seedlings were keP~ covered with about a foot of pond
<br /> water. All species, except silver maple, su[~ived 8 days of complete
<br /> inundation. After 16 days all replications of Willow and green ash
<br /> survived; two of three replications of sweetgum survived; one of three
<br /> boxelder survived; no cottonwood survived. After 32 days, only willow
<br /> survived. Recovery after inundation also varied, Willow and green ash
<br /> recovered fast, foll6wed by cottonwood, sweetgum, and boxelder. The
<br /> species, ranked according to their relative tolerances to complete
<br /> inundation, were willow, green ash, sweetgum, boxelder, cottonwood, and
<br /> silver maple.

<br /> tree species following flooding. Journal of Forestry 59:927-928.
<br />
<br /> The article covers experiments in which green ash, c~ttonwood,
<br /> hackberry, sycamore, cherryhark oak, and pin oak seedlings were tested
<br /> for survival, and root and shoot growth following flooding. Seedlings
<br /> were immersed for 38 days in enough tapwater to cover the surface of the
<br /> soil to a depth of about One quarter Of an inch, after which they were
<br /> removed and measured. The four most vigorous appearing seedlings of
<br /> each species were then kept for another 60 days in mc.let but Well-
<br /> drained soil and remeasured. The results Showed pronounced variation
<br /> associated with soil moisture conditions. Cottonwood, sycamore, and ash
