Niangua darter [Etheostoma nianguae]

The slender Niangua darter is distinguished from all other darters by two small jet-black spots at the base of its tail fin. It has a long head which tapers into a pointed snout. It is a yellowish-olive fish with eight prominent cross-bars on its back, and orange spots scatter its upper sides. This threatened species can grow up to 10 centimeters (4 in) in length. It feeds on aquatic insects and spawns during spring in swift currents over gravel bottoms.

This darter makes its home in the margins of shallow pools with silt-free, gravel or rocky bottoms in clear, medium-sized streams. It is one of 107 different fish species which exist in the Osage Basin of Missouri. In the early 1970's, eight Niangua darter populations were reported along 205 kilometers (128 mi) of the river basin, throughout 12 Missouri counties. The current distribution of the darter has is unkown, but is thought to have decreased considerably from its historic range. However, it is clear that this is a rare species, highly localized in occurrence, and thus is vulnerable to extinction.

The decline of the Niangua darter is largely due to the alteration of its habitat. Reservoir construction along the Osage River has been a large detriment to the the darter, forming insurmountable barriers between tributary streams, limiting the range of the fish and its ability to survive. Highway and bridge construction along the rivers have also impaired the habitat by restricting stream channels and causing sedimentation and silt pollution. The deforestation of the river banks has increased erosion, eliminated shallow pools, and changed the character of the stream flows and floors. The introduction of non-native, predatory species like spotted bass and rock bass for recreational purposes has further threatened the fragile existence of the darter, and of the ecosystem as a whole.

The survival of the Niangua darter is directly linked to the survival of its habitat. Critical habitat has been declared for 145 kilometers (90 miles) of inhabitated stream, and for a 15-meter (50 ft) streambank buffer zone for areas deemed essential to the recovery of this species. Some towns within the range of the Niangua darter are even upgrading their sewage facilities in hopes of enhancing the water quality in the impacted streams.

Missouri bladderpod [Lesquerella filiformis]

The Missouri bladderpod is a winter annual with numerous erect, hairy stems, measuring about 20 centimeters (8 in) in height. Its distinctive silvery leaves are hairy above and beneath, and are elongated and flat near the base of the plant. In late April or early May, bright yellow flowers with four petals bloom. The seed capsule usually splits open and disperses seeds within four weeks after flowering. This bladderpod has occasionally exhibited unusual growth patterns, growing for one or two seasons, disappearing completely the next year, and then reappearing the following year.

Historically, this plant existed in the five Missouri counties between Springfield and Joplin. The bladderpod's current existence, estimated to be fewer than 5,000 plants in 1986, is limited to just nine scattered sites within only three counties of this historic range. The species is found on private and public lands, including the Wilson's Creek National Battlefield Park which contains one third of the total population of Missouri bladderpods. Several populations also occur on highway rights-of-way.

This endangered plant is found in the unusual habitat of open limestone glades, which are often transistion zones between the prairie and the mature oak forests of the mountainous Ozarks. These glades are extremely uncommon in Missouri, and thus produce highly localized populations of the Missouri bladderpod. The suppression of natural fires in limestone glades have allowed for the conversion of the habitat to woody vegetation, specifically to the eastern red cedar in Missouri. The cedar is an extremely invasive tree that is a significant threat to smaller plants like the Missouri bladderpod which cannot adapt to the shade from the thick cedar canopy. However, succession is not the only threat to the bladderpod. Plants located in parks are subject to the stress of high visitor numbers and occasional collection. Improper timing of roadside maitenance (mowing, herbicides) can damage highway rights-of-way populations.

One way to improve and protect the habitat of the bladderpod and other native glade species is to remove eastern red cedars, allowing the sun to shine directly on the rocky ground year round. It is also important that fire be returned to the landscape to preserve the natural balance of the land. In 1995, the Fish and Wildlife Service, along with the Nature Conservancy and the Missouri Department of Conservation, began working on 90 acres of land adjacent to the Rocky Barrens Natural History Area to remove red cedar and conduct prescribed burns. The efforts produced a stunning success, as evident in the spring of 1997 when the land turned bright yellow with a profusion of Missouri bladderpod. In addition to the use of fire for recovery, the Missouri Botanical Garden is prepared to bring this species into protective cultivation under the guidance of The Center for Plant Conservation.

Ozark cavefish [Amblyopsis rosae]

The Ozark cavefish is a true cave-dwelling species in all of its features. It is a tiny fish, growing only to 5 centimeters (2 in) in length. It has an elongated, flattened head, and a projecting lower jaw. It is an albino fish, with its body nearly devoid of any pigment. The fins of this cavefish are locked far back on its body. Due to the darkness of its habitat, the fish has only a trace of where its eyes are located, relying instead on hair-like sensory structures on its tail fin to feel its way through its environment.

The Ozark cavefish is a mysterious creature which is rarely seen. Little is known about its behavior or life history. This fish makes its home in the caves of the limestone formations of the Ozark Mountains. This cave habitat is fragile, offering little diversity or quantity in terms of food supply. For example, when inhabiting caves occupied by the endangered Gray Bat, Ozark cavefish use bat droppings as their primary source of energy.

The historic distribution of this threatened cavefish is largely unkown. It is the only cavefish within the Springfield Plateau of southwest Missouri, northwest Arkansas, and northeast Oklahoma. Currently, the cavefish lives in at least 29 caves of these three states. Although still occurring throughout much of its historic range, the frequency of cavefish sightings is decreasing. On average, one is able to see about five fish at each population site. The existing Ozark cavefish population is highly localized; nearly two-thirds of the known individuals are thought to inhabit a single cave in Arkansas, where up to 100 fish have been observed in one area.

The decline of the Ozark cavefish may be due to degradation of subsurface water, possibly from sinkholes in the soluble limestone or from heavy agricultural use where animal waste seeps into the ground water or flows in from outside streams. Industrial and residential development has also caused water contamination, leaking toxic levels of nickel from urban wastes into at least one cave system. Because of its low reproduction rate and confined habitat, the Ozark cavefish is vulnerable to even casual collecting. For example, it is thought that a scientific collection in the 1930's may be responsible for the very low population of cavefish in one Arkansas cave. Amateur spelunkers also pose a threat to the fragile habitat of this species.

The recovery of the Ozark cavefish seems to rely on public protection of its cave habitats. Arkansas now owns the cave with the largest known population of the cavefish. Missouri purchased another cave which contains a small population of this fish, but has a considerable amount of habitat which may support a reintroduction effort.
