Ecology and Background
The area of union of the Loup River Loup River
River, east-central Nebraska, U.S. It flows east to join the Platte River. It is 300 mi (485 km) long and is harnessed to produce hydroelectric power. Its name is derived from the French name (meaning “wolf”) for the Skidi Indians. system with the Platte River Platte River
River, central Nebraska, U.S. Formed by the confluence of the North Platte and South Platte rivers, it is 310 mi (500 km) long. It flows southeast into a big bend at Kearney, Neb., then empties into the Missouri River at Plattsmouth, south of Omaha. basin near Columbus, Nebraska Columbus is a city in Platte County, Nebraska, 90 miles (148 km) west by north of Omaha on the Loup River, a short distance above the confluence with the Platte. In 1900, 3,522 people lived in Columbus, Nebraska; in 1910, 5,014; and in 1940, 7,632. , provides a collective view of the plants found in both river systems. A comprehensive floristic determination for this area could be valuable for evaluation of future land-use impacts in those large watersheds. Growing threats of climate changes could have significant effects on local plant communities. Establishing accurate lists of species is important for detecting signs of change in our local flora.
With ninety-nine percent of the original tall-grass, mixed-grass and wetland prairies plowed for agriculture or used for grazing, populations of many once-common native species are now drastically reduced. Agriculture and urbanization have significantly altered the landscape for many species. As land-use disturbances continue at a rapid rate, bottomland floras are now more diverse, heterogeneous mixes of plants than in presettlement times. The absence of frequent prairie fires and the invasion of many exotics threaten remaining fragments of native prairie and original bottomland forests.
History of Plant Collecting in Nebraska and Platte County
Published reports of Nebraska's flora begin with explorers Lewis and Clark in 1803-6, Nuttall and Bradbury in 1808, James of the Long Expedition The Long expedition, named after its leader, James Long, was an early attempt by Anglo-Americans to wrest Texas from Spain. The expedition was mounted by a militia from Natchez, Mississippi, who were opposed to the boundary of the Louisiana Purchase. in 1820, the Fremont Expedition in the 1840s, and the Warren Expedition of 1857. Among the early attempts to list Nebraska's complete flora are two catalogues, those of Samuel Aughey (1876) and H. J. Webber (1890). Local studies in the state have produced numerous floristic lists for counties and other areas. A detailed list of such publications from 1804 through 1985 is presented by Kantak and Churchill (1986); others are cited by Kaul et al. (2006). The state's vegetation was mapped at 1:1,000,000 by Kaul and Rolfsmeier (1993), and some detail was shown for Platte County.

The earliest plant collections in Platte County were by Edwin James John Edwin James QC (c.1812 - 4 March 1882) was an English lawyer, Member of Parliament and would-be actor whose professional misconduct led him to end his life in poverty. of the Long Expedition to the Rocky Mountains Rocky Mountains, major mountain system of W North America and easternmost belt of the North American cordillera, extending more than 3,000 mi (4,800 km) from central N.Mex. to NW Alaska; Mt.

The junction of the Loup and Platte rivers at Columbus was a landmark for Pawnee Indians in the 1820s (Ducey 2000). Warren (1875) noted that the valley of the Loup Fork was well wooded as far up as the Pawnee villages to the west of present-day Platte County. The Platte River at Columbus was described as having a sand bottom and many sandbars, and the floodplain floodplain, level land along the course of a river formed by the deposition of sediment during periodic floods. Floodplains contain such features as levees, backswamps, delta plains, and oxbow lakes. was said to be from two to ten miles wide, as it is today. In 1844, Carleton reached the fork of the Loup and Platte Rivers and remarked:
The bed of the river is but one wide expanse of quicksand quicksand
State in which water-saturated sand loses its supporting capacity and acquires the characteristics of a liquid. Quicksand is usually found in a hollow at the mouth of a large river or along a flat stretch of stream or beach where pools of water become partly filled , which is formed in bars and these are continually changing and driving about. The channels are innumerable, but are usually only a foot or so deeper than the surrounding water. The river is filled with beautiful islands. They are all well wooded, but only here and there is there any timber growing upon the main banks. Sometimes we found the channels between the islands and the shore, entirely dry, presenting to the eye a wide extent of sand, which as the wind swept over it, was blown about in clouds, as one would notice on a barren coast of the ocean. The bottomlands are what would be called high river prairie (Carleton 1844-1846 (1983)).
Curry (1950) wrote that when the city of Columbus The passenger steamer City of Columbus ran aground on Devil’s Ridge off of Gay Head Cliffs in Martha's Vineyard, Massachusetts in January 1884. She was owned by Boston & Savannah Steamship Co. and was built in 1878. She was an early iron steamer with a tonnage of 2,200. was founded, prior to 1870, the grass "blue joint" grew thick and matted, was taller than a man's head and common in the area. It was reported to grow between twelve and fifteen feet tall along the sloughs in the area and defied any attempts by primitive plows. (The plant called blue-joint today is Calamagrostis canadensis, which never grows that tall, and perhaps Curry was describing Phragmites australis, common reed, which reaches such height in moist habitats. Calamagrostis canadensis is not on our list of vouchered species, but it is known from several adjacent counties and is undoubtedly in Platte County today.)
The Loup River drains much of the Sandhills, which are less disturbed than most areas of the state, but the substitution of cattle for bison has altered grazing patterns and affected native flora there. The Platte River originates in Colorado and has numerous diversions, with significant irrigation irrigation, in agriculture, artificial watering of the land. Although used chiefly in regions with annual rainfall of less than 20 in. (51 cm), it is also used in wetter areas to grow certain crops, e.g., rice. usage and storage along the entire watercourse. Row-crop agriculture dominates its borderlands.
Our 12-year sampling period, 1996-2007, documents species within the Platte and Loup River bottoms after 150 years of settlement by Euro-Americans in these watersheds. For completeness and comparison, we list all species ever collected in Platte County, as documented by specimens deposited in various university herbaria, especially that of the University of Nebraska-Lincoln, which houses many specimens we collected. The list was assembled from Atlas of the Flora of the Great Plains (Great Plains Flora Association 1977), The Flora of Nebraska (Kaul et al. 2006), and our own observations and collecting. It consists almost entirely of plants collected in the bottomlands of Platte County, because very little collecting has been done in the much-disturbed, heavily agricultural uplands north of those bottomlands, most of whose species also occur in the bottomlands. This congregation of plants of river bottoms appears to be common in the lower reaches of the Platte River.
[FIGURE 1 OMITTED]
[FIGURE 2 OMITTED]
The focus for observations and collection were two primary sites on the Platte and Loup Rivers, where two of the largest watersheds in Nebraska unite (Fig. 1). The Platte River site is Witchey's Island (Fig. 2), a heavily wooded area (but not now a true island) on the north bank of the Platte River, equidistant e·qui·dis·tant
equi·distance n. between Duncan and Columbus on a parcel of property almost a mile in length. Witchey's Island has been grazed only minimally by livestock and natural deer populations, has not had fire for over 100 years, and has never been cultivated or farmed. It was homesteaded in 1864 by John Witchey, and according to historical record he maintained only a small garden and orchard. The Loup River site (Fig. 2) is on the south bank of the river and includes dense bottomland forest with open prairies, all on sandy soil.
The coordinates for most plants collected are as follows:

Lake Babcock, three miles northwest of Columbus, was another sampling location, as was Buck Island on the Loup River southeast of the city. But most collecting was at the established Loup and Platte River study sites because of their ease of access and the intact nature of their flora. The sampling locations were walked during the spring, summer and fall growing seasons, typically on a weekly basis, to identify species not previously vouchered.
RESULTS AND DISCUSSION
The native and naturalized species known so far are summarized in Table 1 above, and the full list of those species follows the text, as Table 2.
The Witchey's Island site is representative of an eastern Nebraska riparian riparian adj. referring to the banks of a river or stream. (See: riparian rights) forest with a mixed-hardwood community, where the tree canopy is Celtis occidentalis, hackberry hackberry: see elm. ; Fraxinus pennslyvanica, green ash; Morus alba, white mulberry; Quercus macrocarpa macrocarpa
cupressusmacrocarpa. , bur oak; and Ulmus americana, American elm. Cottonwoods, Populus deltoides, are present, but not to the large size of those in the Loup River site. The representative shrubs for this community are Cornus drummondii, rough-leaf dogwood dogwood or cornel (kôr`nəl), shrub or tree of the genus Cornus, chiefly of north temperate and tropical mountain regions, characteristically having an inconspicuous flower surrounded by large, showy bracts which ; Ribes missouriense, Missouri gooseberry; Symphoricarpos occidentalis and S. orbiculatus, wolfberry and coralberry; and Zanthoxylum americanum Zanthoxylum americanum,

Abundant woody vines (lianas) form jungle-like tangles: Parthenocissus quinquefolia, Virginia creeper, and P. vitacea, woodbine; Smilax smilax, common name for a florists' plant of two separate genera (Asparagus and Smilax), both of the family Liliaceae (lily family, although some botanists recognize smilax as a separate family, the Similacaceae). hispida, green briar briar: see brier. ; Toxicodendron radicans, poison ivy; Menispermum canadense, moonseed; and Vitis riparia, riverbank grape. The herbaceous her·ba·ceous

2. Green and leaflike in appearance or texture. plants in this community include Carex spp., sedges; Elymus canadensis, Canada wild rye Noun 1. Canada wild rye - North American wild rye
wild rye - any of several grasses of the genus Elymus ; Ageratina altissima, white snakeroot white snakeroot, North American woods perennial (Eupatorium urticifolium) of the family Asteraceae (aster family), having a flat-topped cluster of small white flowers. It is of the same genus as the boneset and joe-pye weed. ; Muhlenbergia spp., muhly grasses; Sanicula canadensis, Canada sanicle; and Viola sororia, sister violet. This community occurs in the floodplains of rivers and streams in the eastern fourth of the state and extends only slightly westward into central Nebraska, along the Loup and Platte River systems. Western wild rose, Rosa woodsii, is more typical of central and western Nebraska, but it is abundant and robust here.
The Loup River site is also representative of eastern-Nebraska riparian woodland, where the tree canopy is represented by cottonwood, many of them 10-30 m in height. The subcanopy contains Acer negundo, boxelder; Gleditsia triacanthos, honey locust; Fraxinus pennslyvanica, green ash; Ulmus americana, American elm; and Morus alba, white mulberry--all common at this site. Shrubs include Cornus drummondii, Ribes missouriense, Sambucus canadensis Sambucus canadensis,
n See elderberry. (elderberry), and Symphoricarpos orbiculatus. Parthenocissus quinquefolia, Toxicodendron radicans and Vitis riparia are also common. Representative herbaceous plants include Ageratina altissima, white snakeroot; Galium aparine, bedstraw bedstraw: see madder.
Any low perennial herbaceous plant of the genus Galium, in the madder family, found in damp woods and swamps and along stream banks and shores. : Geum canadense, white avens avens
Any of the low-growing, perennial flowering plants (approximately 50 species) of the genus Geum, in the rose family. Most occur in the northern or southern temperate zones or in the Arctic. ; Poa pratensis, Kentucky bluegrass bluegrass, any species of the large and widely distributed genus Poa, chiefly range and pasture grasses of economic importance in temperate and cool regions. In general, bluegrasses are perennial with fine-leaved foliage that is bluish green in some species. ; Rudbeckia rudbeckia (rədbĕk`ēə): see black-eyed Susan.

The purple coneflowers (genus Echinacea), found E of the Rockies, have purple to pinkish petallike rays; some cultivated forms have white flowers. ; and Viola sororia, sister violet--all common to abundant.
Recent intrusions of exotic, invasive species are evident: Lythrum salicaria, purple loosestrife loosestrife, common name for the Lythraceae, a widely distributed family of plants most abundant as woody shrubs in the American tropics but including also herbaceous species (chiefly of temperate zones) and some trees. ; Euphorbia esula, leafy spurge; and introduced genotypes of Phragmites australis, common reed. We witnessed their rapid proliferation, but Tamarix ramosissima (salt-cedar) is not yet known in the study area, although it is rampant to the west, along the Platte. Some species apparently are moving upriver, east to west, such as Robinia pseudoacacia Robinia pseudoacacia
toxic tree in the legume family Fabaceae; the bark contains a toxalbumin which causes purging and paralysis. Called also black locust, black acacia, false acacia, locust tree. , black locust black locust: see locust. ; Catalpa speciosa, northern catalpa; and Lonicera tatarica, Tatarian honeysuckle honeysuckle, common name for some members of the Caprifoliaceae, a family comprised mostly of vines and shrubs of the Northern Hemisphere, especially abundant in E Asia and E North America. . The invasive exotics Amur honeysuckle (Lonicera maackii) and autumn-olive (Elaeagnus umbellata) were not present in or near our study sites, but their currently aggressive westward spread across Nebraska assures eventual arrival in Platte County.
The Loup River site has naturalized species such as Rhamnus cathartica Rhamnus cathartica,

An underlying layer of vegetation, especially the plants that grow beneath a forest's canopy. at Witchey's Island, especially in heavily grazed places because livestock do not eat them. Black locust, Robinia pseudoacacia, and northern catalpa, Catalpa speciosa, both native to southeastern North America, are invading the forests near the confluence of the rivers. Siberian elm, Ulmus pumila, and white mulberry, Morus alba, both introduced to North America from Asia long ago, are established and abundant. A native invasive tree, red-cedar (Juniperus virginiana), is abundant in fields and even in deep forests, and here as almost everywhere across the state, it overwhelms native ecosystems.
Some species reach their western limits in or near these sites, e.g., Arisaema triphyllum (jack-in-the-pulpit), Zanthoxylum americanum (prickly-ash), Erythronium albidum (prairie fawnlily), Viola pubescens (smooth yellow violet), and Parthenocissus quinquefolia (Virginia creeper). Others reach their eastern limits in the same area, e.g., Opuntia opuntia
Any plant of the genus Opuntia, the largest genus of the cactus family. Native to the New World, it has characteristic small bristles with backward-facing barbs. fragilis, little prickly-pear.
