Hurricane Katrina/Rita Evacuees

Following the destruction wrought by Hurricane Katrina in late August 2005, the evacuated population of New Orleans, Louisiana, was redistributed throughout America to forty-five states and the District of Columbia. As expected, states in the South took in more of the displaced than the rest of the country. An estimated eighty percent of Katrina evacuees temporarily relocated to Mississippi, Alabama, Texas, Tennessee, Georgia, Florida, or Arkansas. Arkansas received approximately 75,000 evacuees, and Texas initially took in more than 250,000 at the Houston Astrodome, the Reliant Complex, the George R. Brown Convention Center, and other sites in southern Texas. However, no state experienced a population increase larger than Arkansas, whose population jumped 2.5 percent after the evacuees arrived. The first evacuees …

Independence Steam Electric Station

The Independence Steam Electric Station (ISES) is a coal-fired electric-energy-generating plant consisting of two units nameplate-rated at 850 megawatts (MW). Located near Newark (Independence County), the units—constructed by Arkansas Power and Light Company (AP&L, now Entergy Arkansas)—were launched into service in 1983 and 1984 following vigorous litigation before the Arkansas Public Service Commission (APSC) in 1978. The ISES plant burns Powder River Basin low-sulfur coal transported to Arkansas from the Antelope Coal Mine in Wyoming by rail in cars owned by Entergy. ISES—originally proposed by AP&L, Arkansas Electric Cooperative Corporation (AECC), and City Water and Light (CWL) of Jonesboro (Craighead County), and now also co-owned or leased by several other Arkansas municipal utilities—operates in coordination with other generating plants within …

Invasive Animals

aka: Alien Animals
An “invasive species” is defined as a species that is non-native (or alien) to the ecosystem under consideration and whose introduction causes or is likely to cause economic or environmental problems or harm to human health. It typically matures and reproduces quickly and increases its geographic range rapidly, establishing populations and persisting over large areas. There are several reasons for this spread, including favorable environmental conditions and lack of natural predators, competitors, and diseases that normally regulate their populations, allowing invasive species to thrive. Invasive biota not only includes a variety of plants but also incorporates a wide variety of invertebrates and higher taxa from their native sites. As invasive species extend and dominate ecosystems, they invariably reduce native biodiversity …

Invasive Plants

aka: Exotic Plants
According to the U.S. Department of Agriculture (USDA) Forest Service, an invasive species is “a species that is non-native or alien to the ecosystem under consideration and whose introduction does or is likely to cause economic or environmental harm or harm to human health.” As such, there are a suite of negative effects from exotic plant species that include replacing rare and endangered species, hybridizing and competing with native species, killing trees and shrubs, altering hydrological patterns and stream function, preventing forest regeneration, possibly containing toxins that may be lethal to certain animals, changing fire patterns, and harboring pathogens. The cost to control invasive species and the damages they cause to property and natural resources in the United States is …

Ivory-billed Woodpeckers

aka: Campephilus principalis
Long believed to be extinct, the ivory-billed woodpecker (Campephilus principalis) was apparently rediscovered in the Big Woods of east Arkansas in 2004. More than sixty years after the last confirmed sighting in the United States, a research team announced on April 28, 2005, that at least one male ivory-bill survived in the vast bottomland swamp forest. Published in the journal Science, the findings included multiple sightings of the elusive woodpecker and frame-by-frame analyses of brief video footage. The evidence was gathered during an intensive year-long search in the Cache River and White River National Wildlife Refuges in eastern Arkansas, involving more than fifty experts and field biologists working as part of the Big Woods Conservation Partnership, led by the Cornell …

Kudzu

Kudzu (Pueraria lobata) is an invasive vine characterized by aggressive growth and clusters of grape-scented purple flowers. It was recognized as a weed in 1972 by the U.S. Department of Agriculture (USDA). A native plant of Asia, kudzu has been used for over two millennia in Asian cooking and medicine. Kudzu was introduced to the United States at the Philadelphia Centennial Exposition (1876) and to southerners at the New Orleans Exposition (1884–1886). Kudzu’s foothold in the American South is largely the result of the efforts of Charles Pleas, Channing Cope, and the Soil Conservation Service (SCS). Pleas owned Glen Arden Nursery in Chipley, Florida, along with his wife, Lillie. After Pleas discovered kudzu’s usefulness for livestock forage and as a …

Little Rock Garden Club

The Little Rock Garden Club (LRGC) held its first meeting in 1923 at the home of Mrs. J. N. Heiskell (Wilhelmina Mann Heiskell). Other charter members were Mrs. J. F. Loughborough (Louise Loughborough), Mrs. J. W. House (Julia Clarke House), Mrs. Moorehead Wright (Hildegarde “Hillie” Penzel Wright), Mrs. George R. Mann (Carrie Rock Mann), Frances Van Etten, Mrs. Shelby England (Lita England), Mrs. W. D. Cammack (Katherine Broaddus Cammack), Mrs. Homer Scott, and Mrs. Robert Butterfield (Alvan Butterfield). In 1929, the club became a member of the National Garden Clubs, Inc. In 1931, it was a founder of the Arkansas Federation of Garden Clubs, Inc., and in 1960 became a member of the Garden Club of America. In 1928, under …

Lost 40

The Lost 40 is a forty-acre tract of mature forest along Wolf Branch (a tributary of Moro Creek) in southeastern Calhoun County. Owned by PotlatchDeltic Corporation, the tract is known for its large trees, some more than 200 years old, and has variously been described as “primary,” “virgin,” and “old-growth.” It has been the site of several scientific studies conducted by the faculty and students of the University of Arkansas at Monticello (UAM) School of Forestry and Natural Resources, and is protected by a forty-year cooperative management agreement between PotlatchDeltic and the Arkansas Natural Heritage Commission (ANHC) signed in 1996. Lost Forty Brewing, a brewery based in Little Rock (Pulaski County), takes its name from the tract. Several natural communities …

Mammoth Spring

Mammoth Spring is the largest spring in the state of Arkansas, the second largest in the Ozark Mountains region, and the seventh largest in the United States. This National Natural Landmark is located within the boundaries of Mammoth Spring State Park. Approximately 497 feet from the Missouri state line in north-central Arkansas, it is within sight of U.S. Highway 63 and the city of Mammoth Spring (Fulton County). Though the spring has always been known as “big” or “mammoth,” the first known settlers in the 1820s created a small village called “Head of the River,” which would later be renamed Mammoth Spring. Water flows from the spring at an average rate of 9.78 million gallons per hour, with a constant …
