The prelude to the flood began in August 1926, when rainstorms began to swell streams in eastern Kansas, northwestern Iowa, and part of Illinois, all of which fed into the Mississippi River. In December, heavy rains in Oklahoma, Arkansas, and northern Louisiana filled the Arkansas and Red rivers. During that fall, record rainfalls continued throughout the Mississippi River valley. By the end of January, major tributaries such as the Ohio River were overflowing their banks. In earlier times, this would not have been the problem it was in 1927; the Mississippi River and its tributaries once overflowed into natural drainage areas. But in the late 1800s, the Mississippi River Commission adopted a "levees-only" policy, which entailed the construction of levees that ran almost the full length of the river. While these levees prevented flooding for a period, they proved unable to withstand the floodwaters of 1927." –"Great Flood of 1927,"

clearcutting reproduces a new even-aged stand by completely removing the mature stand.

clearcutting as a silvicultural treatment has several characteristics:

it causes a sudden environmental change

it removes the seed source from the regeneration area

the configuration of the clearcut may affect seed dispersal

it begins a new rotation

it will eliminate some pests that require forest cover

overall, it temporarily removes the forest cover, transforming the forest community and environment.

clearcutting followed by artificial (seeded or planted) regeneration has several advantages:

we can avoid delay in restocking the site

we can introduce a selected species, seed source, and genotype

we can control arrangement and spacing

we can achieve uniformity in the new stand

we can overcome the problems associated with securing sufficient natural regeneration.

the shelterwood method involves the removal of most of the mature stand at the end of the rotation, but a portion of the mature stand is left standing.   the shelterwood method serves three basic purposes:

to prepare the stand for production of abundant seed

to modify the environment in a way that promotes germination and survival of the selected species

to build up the amount and size of advance regeneration to ensure the prompt restocking of the new stand following overstory removal.

the shelterwood method involves a sequence of 3 cuttings:

preparatory cuttings: make the seed trees more vigorous and set the stage for regeneration. see our thinning page for more information.

establishment/seed cuttings: open up enough vacant growing space to allow establishment of the new regeneration.

removal cuttings: uncover the new crop to allow it to fill the growing space.

the residual trees in the shelterwood must:

be sturdy and windfirm

be able to survive exposure

flower and reproduce seed

be the best trees of the mature stand

keep in mind that the shelter trees must not occupy the entire site.   a void must be created in order to make room for the new regeneration. the amount of shelter to leave will depend on the following factors:

species characteristics (seeding and shelter requirements)

the number of cuttings in the cutting sequence (1, 2, or 3)

landowner objectives

the size of the area to be regenerated

the final removal harvest level required to be profitable

the shelter must be removed before it impedes the growth of the new stand or threatens its survival.

i'm not sure what you are asking, but it also served as a debtors colony, was ran by the trustees for 20 years until becoming a royal colony, and people had restrictions such as no slaves, and only 50 acres of land per person/ hope this !
