In
early December it was 19ºC. It
felt like a spring day when we
drove to Full Circle Family Farm from our camp site in East Asheville
KOA, Swannanoa near Black Mountain, North Carolina.
Whenever
we go to the farm we offer to help out in some way. Leon gave
Randal and I the job of racking leaves off the newly planted grass in
the field near the chicken yard.
Leon called it his “Savannah”
A savanna,
or savannah,
is a grassland ecosystem characterized by the trees being
sufficiently widely spaced so that the canopy does not
close. The open canopy allows sufficient light to reach the ground to
support an unbroken herbaceous layer consisting primarily
of grasses. The oak savanna is a common type of
savanna in the Northern Hemisphere. Some classification systems also
recognize a grassland savanna from which trees are absent. This
article deals only with savanna under the common definition of a
grassy woodland with a significant woody plant component.
It
is often believed that savannas feature widely spaced, scattered
trees. However, in many savannas, tree densities are higher and trees
are more regularly spaced than in forest. Savannas are also
characterized by seasonal water availability, with the majority of
rainfall confined to one season. Savannas are associated with several
types of biomes. Savannas are frequently in a transitional
zone between forest and desert or grassland. Savanna covers
approximately 20% of the Earth's land area.
Biomes are
climatically and geographically defined as contiguous areas with
similar climatic conditions on the Earth, such as communities of
plants, animals and soil organism and and are often referred to as
ecosystems.
Randal
and I racked a large portion of the field and throw the leaves into
the chicken yard. They were happy and began to scratch an spreading
them around.
