History
This is what is in the first paragraph of the article:

Human habitation has been established for 7000 BC.[citation needed] The Arikara arrived by AD 1500, followed by the Cheyenne, Crow, Kiowa and Pawnee. TheLakota (also known as Sioux) arrived from Minnesota in the 18th century and drove out the other tribes, who moved west.[6] They claimed the land, which they called Ȟe Sápa (Black Mountains). The mountains commonly became known as the Black Hills.

I will add the paragraph below to the history of the black hills:

Although written history of the region begins with the Sioux domination of the land over the native Arikara tribes, researchers have carbon-dating and stratigraphic records to analyze the area. Scientists have been able to utilize carbon-dating to evaluate the age of tools found in the area, which indicate a human presence that dates as far back as 11,500 BCE with the Clovis Culture. Stratigraphic records indicate environmental changes in the land, such as flood and drought patterns. For example, large-scale flooding of the Black Hill basins occurs at a probability rate of 0.01, making such floods occur once in every 100 years. However, during The Medieval Climate Anomaly, or the Medieval Warm Period, flooding increased in the basins. A stratigraphic record of the area shows that during this 400 year period, thirteen 100-year floods occurred in four of the region's basins, while the same four basins from the previous 800 years only experienced nine floods.

Plagiarism correction:

The "history" section of the article opens with the sentence, "Human habitation has been established for 7000 BC." However, there is no citation listed for this fact (there is a footnote for "citation needed"), and the link "human habitation" leads to the Wikipedia page "Paleo-Indians", an article on the Paleolithic people of North America and their human geography. In this referenced article as well as the article I am citing by Bob Patten, the reader can see that human habitation has been established since 11,500 BCE with the Clovis Culture, and the proof of their presence is in carbon-dated tools found the area.

Article 2: The Great Flood of 1927; Events
The article had said in the second paragraph of this section: "Flooding overtopped the levees, causing Mounds Landing to break with more than double the water volume of Niagara Falls. The Mississippi River broke out of its levee system in 145 places and flooded 27,000 square miles (70,000 km2). This water flooded an area 50 mi (80 km) wide and more than 100 mi (160 km) long. The area was inundated up to a depth of 9 m (30 ft). The flood caused over US$400 million in damages ($5,623,529,411 in 2016 [1]) and killed 246 people in seven states."

I have edited this information as it is repetitive, and some of the facts that are repeated are repeated incorrectly within this one paragraph. Either they are incorrectly repeated, or it is not stated clearly enough, which might cause confusion. There are also no citations for any of the facts listed in the paragraph. I researched to see if the figures listed were correct, and they are not. I have made corrections have peer-reviewed sources to confirm.

I will change the paragraph to:

"Flooding peaked in the Lower Mississippi in Arkansas, near Mounds Landing and Arkansas City, and broke along the river in at least 145 places. The water flooded more than 70,000 square kilometers of land, and left more than 700,000 people homeless. Approximately 500 people died as a result of flooding. Monetary damages due to flooding reached approximately $1 billion, which was one-third of the federal budget in 1927. If the event were to have occurred in 2007, the damages would total around $130 billion or $160 billion (measured in 2007 U.S. dollars)."

Article 3: Hurricane Katrina
I added this paragraph:

Katrina also produced massive tree loss along the Gulf Coast, particularly in Louisiana'a Pearl River Basin and among bottomland hardwood forests. Before the storm the standard mortality rate for the area's trees was 1.9%, but this interval increased to 20.5% by the end of 2006.[104] Delayed mortality as an effect of the storm continued with rates up to 5% until 2011.[105] This significant loss in biomass caused greater decay and an increase in carbon emissions. For example, by 2006 the decreased biomass in bottomland hardwood forests contributed an amount of carbon which equated to roughly 140% of the of the net annual U.S. carbon sink in forest trees.[106]

All of my sources are peer-reviewed. The paragraph includes information on loss of tree life because of Hurricane Katrina, and focuses specifically on the Louisiana Pearl River Basin. The most significant loss of trees in any area affected by the storms was among bottomland hardwood forests, another focus of my edit. Along with the statistics of loss of tree life, I include information and more statistics on how this increased carbon emissions for the area.
