Harper Habitat Protection Specialist Massachusetts Natural Heritage and Endangered Species Program Westborough, Massachusetts For: New England Wild Flower Society 180 Hemenway Road Framingham, MA 01701 508/877-7630 e-mail: [email protected] • website: www.newfs.org Approved, Regional Advisory Council, 2002 SUMMARY Desmodium cuspidatum (Muhl.) Loudon (Fabaceae) is a tall, herbaceous, perennial legume that is regionally rare in New England. Found most often in dry, open, rocky woods over circumneutral to calcareous bedrock, it has been documented from 28 historic and eight current sites in the three states (Vermont, New Hampshire, and Massachusetts) where it is tracked by the Natural Heritage programs. The taxon has not been documented from Maine. In Connecticut and Rhode Island, the species is reported but not tracked by the Heritage programs. Two current sites in Connecticut are known from herbarium specimens. No current sites are known from Rhode Island. Although secure throughout most of its range in eastern and midwestern North America, D. cuspidatum is Endangered in Vermont, considered Historic in New Hampshire, and watch-listed in Massachusetts. It is ranked G5 globally. Very little is understood about the basic biology of this species. From work on congeners, it can be inferred that there are likely to be no problems with pollination, seed set, or germination. As for most legumes, rhizobial bacteria form nitrogen-fixing nodules on the roots of D. cuspidatum. It is unclear whether there have been any changes in the numbers or distribution of rhizobia capable of forming effective mutualisms with D.

Don] is a perennial legume first introduced to North America from eastern Asia in 1896 and is now widespread and well established across much of the eastern and central United States. Possible impacts of invasion and mechanisms of spread however are poorly understood. I assessed the influence of three L. cuneata cover classes (i.e., < 5%, 15 – 20%, and > 25% per m2) on a small mammal community in eastern Oklahoma (February 2010 to December 2011). I also examined the relationship between local fire history and L. cuneata cover and also considered the effect of plant invasion on the vegetation community in these same areas. My results indicate small mammal community diversity decreased with increasing L.

LESPEDEZA Description Kummerowia stipulacea Korean and common lespedeza (Kummerowia striata) are introduced, annual, warm-season (Maxim.) Makino legumes. Flowers and seeds are borne in the leaf Plant Symbol = KUST axils at the tips of stems and branches in the Korean lespedeza and in the leaf axils all along the stem in Contributed by: USDA NRCS Northeast Plant common lespedeza. Two types of flowers are Materials Program produced. One is readily seen as purple-bluish and the other has no petals and is inconspicuous. Korean lespedeza has a much broader leaflet and stipule than common, and growth is generally larger and coarser. Common lespedeza grows more prostrate. The seed varies from the shiny black of Korean to the stippled seed of common. There are approximately 343,000 seeds per pound of common lespedeza and 240,000 seeds per pound of Korean lespedeza. Adaptation and Distribution Korean is better adapted than common lespedeza in the North because of its shorter life cycle. Both types grow in a pH range of 4.5-7.0, but do best at 6.0-6.5. Common lespedeza (cultivar ‘Kobe’) is more tolerant of acid soils. They both grow in soil textures ranging from sands to clays and at fertility levels from low to high. From Delaware Wildflowers Korean lespedeza is distributed throughout the midwest and eastern United States.

  • Lespedeza Bicolor (Shrub Lespedeza, Bicolor Lespedeza)
    No. 17 April 2010 Lespedeza bicolor (Shrub Lespedeza, Bicolor Lespedeza) Initial Introduction and Expansion in Range Introduced to the United States in the late 1800s from Japan, Lespedeza bicolor now occurs throughout most of the Southeast from Arkansas to Maryland, and south to Florida and Texas. It can be found statewide in North Carolina. It was introduced primarily to provide food and cover for bobwhite quail and other popular, upland, game birds. Additional uses include erosion control, stabilization along stream banks and steep slopes, and landscaping for borders and hedges. The ability of this plant to fix nitrogen has also resulted in its use for re-vegetation of disturbed, infertile sites, particularly areas that have been burned. As with other species of Lespedeza, it responds positively to burning, enabling this plant to outcompete native plants on sites that have been disturbed by fire. The seeds of L. bicolor are readily dispersed by birds, allowing it to escape cultivation and invade open areas where it can form dense thickets that displace native vegetation. It is less common than L. cuneata (Sericea, Korean, or Chinese lespedeza) which is still widely planted for erosion control and its alleged benefits for wildlife forage. Description and Biology • Upright, loosely branched deciduous shrub, 4 to 10 feet in height with many slender branches. • Leaves are compound in groups of three arranged alternately along the stem. • Rosy-purple, pea-like flowers appear in the late summer. • Small, black seeds singly produced in flat pods that open when mature. Seed maturity occurs from late September to early October.

    Iowa Habitat Loss and Disappearance IowaAssociationofNaturalists Iowa Environmental Issues Series Iowa Habitat Loss and Disappearing Wildlife Iowa Habitat Loss and Disappearing Wildlife Habitat and wildlife Iowa habitat owa was once a land dominated by prairie and scattered prairie I wetlands. Thick woodlands and forested wetlands bordered its rivers and streams and covered the rugged landscape of northeast Iowa. The numerous interior streams meandered their way to the great border rivers - the Mississippi and the Missouri. Since Euro-American settlement, however, the historic Iowa landscape has been drastically changed, replaced by farms, towns, and highways. The once dominant Iowa prairie has been reduced to Iowa’s most rare and endangered habitat. Habitat refers to the features of an area that allow a wildlife species to live there. Although some types of wildlife may have many specific habitat needs, all wildlife have four basic habitat requirements: • adequate supplies of the right types of food; • available structure and materials that provide shelter to serve as safe places to live and raise young; • accessible and adequate supplies of water; and • enough space to find these necessary resources and to exercise natural behavior. When a wildlife species can no longer find enough food, water, shelter, or space, its habitat has been lost. Wildlife habitat is lost when land is cleared, polluted, or otherwise altered. IowaAssociationofNaturalists 1 Iowa Habitat Loss and Disappearing Wildlife Habitat is often described in terms of biological communities or habitat types. In addition to prairies, other habitat types include woodlands, wetlands, and waterways such as rivers and streams. Like prairies, these habitat types also have been lost or altered.

    August 3, 2005 version Official Assessment of Lespedezas (including L. cuneata, L. bicolor, L. thunbergii, Kummerowia stipulacea, and K. striata) in Indiana’s Natural Areas Assessed July 6, 2004- by Ellen Jacquart, Gary Langell, Phil O’Connor, Lee Casebere, and Ed Guljas Answers are underlined, comments and discussion are in italics. Contents of the Assessment: Section I – Invasion Status. Determines whether the species being evaluated is invasive in Indiana. Section II – Ecological Impacts of Invasion. Evaluates the significance of impacts of the species. Section III – Potential for Expansion. Evaluates the actual and/or potential expansion of the species. Section IV – Difficulty of Management. Evaluates how hard it is to control the invasive species. Section V – Commercial Value. Evaluates how valuable the species is economically in Indiana. Questions in Sections I – V may direct you to one or more of the following sections for particular invasive species: Section A. For species which have impacts limited to a few sites, assesses the potential for further spread. Section B. For species which have medium impacts but high value, assesses whether species could be used in specific circumstances that would prevent escape and invasion. A worksheet for use with the assessment is found on page 10. The meeting started with a summary of the Asian lespdezas to be assessed. They fall into three groups: Sericea lespedeza: L. cuneata is a perennial lespedeza with woody stems, well known and planted for many years for wildlife purposes and for erosion control on poor soils. Most Indiana agencies have already stopped planting it or recommending it because of its aggressiveness.

Interesting Fact: Bicolor Lespedeza was heavily promoted for Northern Bobwhite Quail in the 1950s. While quail do feed on the seeds, studies have shown that Bicolor Lespedeza does not provide great habitat for the birds. Description: Bicolor Lespedeza, also known as Shrub Lespedeza, is an herbaceous perennial in the Legume Family that can grow up to 10-12 ft. tall and wide. It has alternate, compound leaves and flowering racemes of red-purple flowers that turn into small single-seed pods when ripe. Defining characteristics: • Alternate, compound leaves with 3 leaflets per leaf • Leaves have lighter colored undersides • Flowering racemes of red-purple flowers at the end of branches in late Summer to early Fall • Fruit is small seedpods (legumes) with one seed per pod.
