[9] An increase in the growth of Bermuda grass is seen in fields where pre-emergence herbicides are used to control annual weeds. comm., Diamond pers. [48] Silberman (pers. A successful restoration project, restoring cottonwoods and willows to a 40 acre Bermuda grass pasture in California, resulted in maximum control with glyphosate alone (Tiller pers. It is rich in calcium, phosphorus, fiber, potassium and protein which bestow a wide range of health benefits. [30] The initial stolons move away from the center shoot in straight lines. Crampton, B. Cynodon dactylon, a monocot, is a perennial grass that is not native to California; it has been naturalized in the wild. Most biotypes are infertile, and those that are fertile tend to produce sparse amounts of seeds. Oren Pollack, Stewardship Ecologist, California Regional Office, The Nature Conservancy, 785 Market St., 3rd Floor, San Francisco, CA 94103; (415) 777-0487. [18] The total rhizome length of single node rhizome fragments planted in July increases from 36 m per plant in December to 95 m the following July, indicating greater rhizome growth in early summer than in late summer. California Agricultural Experiment Station Bulletin 724:3-130. Cynodon dactylon and Acacia smallii were grown in mixed and mono-culture plots, with and without added fertilizer in order to study the competitive ability and mechanism of the two species. Thus, although abundant throughout the world, the threat from the invasion of this plant is limited to warm, sunny, disturbed sites. Fertilizer. Rhizomes grow in the same configuration as the above-ground growth and are not found growing outside of the sod perimeter. Burning, herbicide application, clipping and shading have all been effective in controlling Bermuda grass under various conditions. Combinations of herbicides and tilling were less effective. Bermudagrass, Bahamas Grass, Devil's Grass, African Couch, Star Grass, Wire Grass Cynodon dactylon is naturalized in Texas and other Tates ans is considered an invasive plant in Texas. B. Youngner, F. J. Nudge and J. J. Chatterton. USDA miscellaneous Publication No. [40], Asexual reproduction, not sexual reproduction, is responsible for the spread of most Bermuda grass. Presently no formal monitoring programs of Bermuda grass are known. Although Cynodon dactylon is considered the world's weediest grass, eradication appears to be feasible. You can change the display of the base map and layers by clicking on the layer control box in the upper right-hand corner. Cyperus polystachyos . Fire: its effect on grasslands, including swamps-southern, central and eastern Africa. Vegetative Characteristics Blade Hairy: N Blade with White Margin: N Blade Cross Section: Flat Blade Notes: Blades short, narrow, 1/2 to 2-1/4 inches long to 1/8 inch wide. Forages the science of grassland agriculture. The best management practice is to avoid the initial invasion of Cynodon dactylon by limiting soil disturbances and maintaining a vegetation cover. The name is Bermuda Grass because it was first introduced in the USA from Bermuda. [9][3], In addition to high temperatures, Bermuda grass requires high light intensities. [20], Increasing the level of nitrogen results in a decreased amount of reserve carbohydrate. Horowitz, M., and T. Friedman. [33] Stunted growth of Cynodon dactylon occurred in high wheat density plots. Temperature factors limiting the spread of Cogongrass (, Cohn, E., O. VanAuken, and J. Bush. Box 1662, Weldon, CA 93282; (619) 378-2531. Plant Characteristics: Perennial that could spread by stolons, rhizomes or seed. [9] Concentric growth, outward from the original rhizome sprout, of the rhizomes corresponds to the circular above-ground growth pattern. It … Bermuda grass's high pollen production leads to its notoriety as a major contributor to allergies. Studies on the biotypes of, Newman, D. 1989. 178 pp. Bermuda grass originally came from the savannas of Africa and is the common name for all the East African species of Cynodon. There is a hairy ligule present. Tall Timbers Fire Ecology Conference 11:175-199. These rhizomes growing deep in the soil provide an over-wintering structure as well as, when they surface, additional above-ground growth.[19]. [29] Aerial growth from shoots, tillers and previous season's rhizomes produce an abundance of stolons, which in turn produce more shoots, rhizomes and roots. New rhizomes form only at temperatures greater than 15° C to 20° C; sprouting of rhizome buds is maximal at temperatures between 23° C and 35° C and is inhibited by temperatures below 10° C.[18] No dormancy period is found in rhizomes; sprouting occurs once apical suppression is relieved by fragmentation. Effects of frequent clipping on three perennial weeds. [36], The increase in the amount of Cynodon dactylon due to cattle grazing is well documented. Invasion will be limited by tall plants. University of Arizona, Tucson, Arizona. [30] A random sampling of segments of the infested field may provide sufficient information for large scale problems. Therefore, an artificial, simulated rainfall experiment study is conducted to determine the effect of rainfall intensity and vegetation cover on runoff volume, sediment load, and runoff hydraulics characteristics. With high levels of shade the plant can no longer grow; thus shading can be used as a control method. University of California Press, Berkeley, California. Modoc. Burton, G., and W. Hanna. These reduce the competition of annual grasses allowing the rhizomes and stolons of Bermuda grass to thrive. Bermuda grass is susceptible to desiccation. Effects of desiccation and submergence on the viability of rhizome fragments of Bermudagrass and Johnson grass and tubers of Nutsedge. Most of these techniques are not economically or practically feasible in a non-agricultural setting. If appropriate, planting of tall plants between the invaded and non-invaded sites may prevent spreading into the exposed area. Sources of variation in. [4] In areas of low rainfall it commonly grows along irrigation ditches and streambeds. Spreading of Cynodon dactylon is exacerbated by the continued planting of this turf and forage crop. Coppice Potential. Total available carbohydrates in grasses and legumes. 2b. Carbohydrate accumulation of coastal Bermuda grass and Kentucky bluegrass in relation to temperature regimes. comm.) A wiry perennial grass with creeping stolons and rhizomes. [17] The cultivar and the environmental conditions greatly influence the reserve carbohydrate quantity and quality. Shade tolerance studies on Bermudagrass and other turfgrasses. Cynodon dactylon can be an invasive and competitive weed. California Press, Berkeley. treatment of many symptoms and diseases like cramps, measles, tumors, wounds, warts, fever. In order to prevent the sprouting and establishment of the remaining Bermuda grass rhizomes, native plants and shade material should be installed immediately after the eradication stage. 1051 pp. University of Arizona Press, Tucson, Arizona. and rheumatic affections. [32] C. dactylon grew 1.5 to 2.4 times larger in mixed cultures than in mono-cultures, with a yield increase of 30% to 50% when grown with Acacia. This is followed by the secondary stolons growing in all directions to form dense circular mats of sod. Also by a vast system of hard, sharp-pointed rhizomes beneath the ground which may be shallow or very deep. comm., ).[47]. 200. Agronomy Journal 62:285-287. The effects of late winter litter burn on the composition, productivity, and diversity of a 4-year old fallow-field in Georgia. [10][4] Large amounts of Bermuda grass, including the giant-type, grow along the edge of Roosevelt dam in Arizona, where it survives submergence under water for part of the year and provides food for cattle during the dry periods. [42][45] This technique is impractical in large scale infestations. University of Arizona, Tucson, Arizona. The experiment consists of seven vegetation treat… The sod area is proportional to the number of inflorescences with an average of 78 inflorescences per square meter of sod the first year. CROP/SPECIE CULTIVARS SEEDING GRAM/SQUARE METER SUITED REGIONS PLANTING MONTHS USES Cynodon dactylon Yukon 20 The whole of South Africa Autumn/Spring Lawns for landscaping, sport and athletic fields As many as 12 tillers sprout and three dormant rhizome buds develop from these shoot buds. Herbicide application in conjunction with tilling and desiccation may be the most effective control technique. Bermudagrass (Cynodon dactylon) is one of the most important species in the Southeastern United States with ~ 25–30 million acres planted for livestock grazing and hay. Jameson, D. 1963. [18] Growth of rhizome buds varies depending on depth in soil and age of rhizome. This plant requires high light intensity to thrive. Val Little, Preserve Manager, Hassayampa River Preserve, The Nature Conservancy, Box 1162, Wickenburg, AZ 85358; (602) 684- 2772. [31] Native vegetation recovery, due to the competitive ability of knotgrass (Paspalum sp. 1954. Cynodon dactylon . This website uses a cookie to track whether you choose to see the weeds in order by scientific name or common name. Burton, G., J. Jackson, and F. Knox. Plant residues and actively growing plant parts of Cynodon dactylon may pose a direct threat to the growth of neighboring plants. Common Bermuda grass, also known as Couch Grass or Wiregrass is scientifically called the Cynodon dactylon. [15] Results on the survival of Bermuda grass growing under trees indicate that the grass will die when completely shaded by closed canopies[15]. Sites with established Bermuda grass where restoration projects include re-vegetating with short-stature plants: A more severe eradication procedure is necessary when the native vegetation will not shade the Bermuda grass. In general, if conducted at the correct time, burning will slow down the growth of perennial grasses. Leaves are rolled in the bud and the ligule is hairy. In general, root growth and germination are both affected by decaying residues and actively growing Cynodon dactylon plants. Knowledge of the extent of the underground rhizome and root system is important for manipulating the entire infested area; no additional measurements are required since the underground growth pattern parallels the aerial development. 1983. 9:534-537. 1986. Location. Cynodon dactylon(Poacae) is a well known traditional plant used as a folk remedy in. Growth is promoted by the addition of lime to soils with a pH of 5.5. hetero 54 . [9][3] The rhizomatous and stoloniferous growth and, depending on the cultivar, the abundance of minuscule seeds, leads to the extensive spreading capabilities of Bermuda grass. comm.). [27] The importance of the allelopathic substances produced by Bermuda grass in the field is unclear. Periodic spot control or shade mats placed around the young plants may be necessary during the establishment of the native plants. Recovery of N15-labelled fertilizer by coastal Bermudagrass in lignite minesoil. Subterranean growth begins earlier in the spring than aerial growth. [30] In two and a half years the average sod area of a single plant is 25 m2, with a maximum growth rate of 2 m2 per month in the summer months. The culms (stems) take root at the lower nodes. Long rhizome fragments and dormant stolons require long periods of drying in order to destroy the activity of the buds. [30] Other investigators report the existence of rhizomes 1 m deep. Previous studies have shown that the use of vegetation is an effective way to control soil erosion. Phytotoxicity of subterranean residues of three perennial weeds. 1987. Establishment: Extremely drought tolerant and can be planted throughout the state. Chase, and D. Hedrick. Rensburg, H. 1970. [32], Studies on competition in mixed plots of wheat and Cynodon dactylon showed similar intra- and inter-specific competition for nutrients when plants were planted at the same time. Cutting Bermuda grass on hot, dry days has a much greater inhibitory effect than cutting on cool, moist days. Humphrey, R. 1977. Uninfested sites with complete canopy cover surrounded by areas containing Bermuda grass: Most likely this situation will not require any active management since Bermuda grass rarely invades undisturbed sites. [25][26] Air drying of one-node rhizome fragments for seven days resulted in the inhibition of sprouting and a 53% weight loss, however three-node rhizome fragments continued to sprout after seven days of desiccation. Negative: On Aug 10, 2006, Jaimee from Farmington, MI wrote: This weed is also called "Devil's Grass" because it is such an evil weed. A substantial amount of the world's salable seeds of this "giant" Bermuda grass is grown near Yuma, Arizona. Ron Tiller, Preserve Manager, Kern Reserve, The Nature Conservancy, P.O. Leaves are gray-green to blue-green short (2 to 8 in long) and narrow (2 to 5 mm wide). The percent coverage, timing of shading and types of shading material, such as shade cloth, shade mats, trees and other plants, should be studied in order to maximize the shade sensitivity of the species. Tall Timbers Fire Ecology Conference 15:223-233. Effect of nitrogen and shading on yield and quality of grasses grown under young slash pines. In addition, seed production decreased with increased densities of Bermuda grass. California Press, Berkeley. This page was last modified 20:40, 18 June 2014 by. Rochecouste, E. 1962a. [30] This growth pattern explains the tremendous spreading capacity of Bermuda grass; the highest monthly area increase was 6 m2 during July and August. [19] In the first month a primary shoot and four roots develop from the rhizome. [9] [30], Single-bud rhizomes were planted and monitored throughout several growing seasons. The World's Worst Weeds: Distribution and Biology. [20] The greatest amount of growth occurred at 30° C/24° C (day/night temperatures) whereas the greatest amount of starch in the stem bases and rhizomes of Coastal Bermuda grass occurred in the 13° C/7° C treated-plants. However, enough plants usually persist to cause weed problems. Uninfested sites with bare or unshaded spots surrounded by areas containing Bermuda grass: If the site is undisturbed than most likely Bermuda grass will not invade it. Zea mays, Cynodon, Poa, Saccharum are used as fodder. The rhizome system is superficial as well as deep, which may account for the ability of this species to infest both arable and waste lands in a variety of conditions. The best management strategy is to remove all plant parts at first sighting. Cynodon dactylon however, has become a "ubiquitous, cosmopolitan weed". 1974. Bermuda Grass (Cynodon dactylon) Care. [12], An increase in nitrogen fertilizer from 0 to 900 pounds per acre results in an increase in height (2.5 inches to 6.5 inches), percent protein, yield (1.6 tons to 11.0 tons of hay), stem length (6.0 to 17.0 inches), internode length and node number, and a decrease in leaf percentage and seed head frequency (5% to 2%). Maximum extension is measured by determining the distance from the center of the sod to the tip of the furthest stolon. [30] Germination tests will determine the fertility status of the variety in question. The Plants Database includes the following 2 subspecies of Cynodon dactylon . Hitchcock, A. S. and A. Horizontal growth commences when the primary shoot and tillers reach 10 cm to 15 cm long, resulting in the formation of stolons. [44] In addition to reducing the regrowth of shoots, the initial clipping inhibited the formation of flowering stalks. comm.). Ross, M. 1986. Cynodon dactylon, This is a warm season perennial grass spreads both by stolons and rhizomes and forms a prostrate habit. Authors: Dara Newman, Global Invasive Species Team, The Nature Conservancy. When nitrogen is limiting, and the growth conditions unfavorable, fructosans accumulate in the rhizomes. Element Stewardship Abstract-, Carey, Jennifer H. 1995. Agronomy Journal 51:367-368. Productivity and plasticity of wheat and. The effects on carbohydrate reserves of nitrogen amendments to shaded plants should be analyzed. University of Arizona, Tucson, Arizona. Tagging the edge of each cluster yearly may help in visually assessing the expansion or reduction in the infested area and in rapidly locating the problem site. 1981. 1986b. The collar often has long hairs and the ligule is a tuft of hairs. [18] The depletion of carbohydrates is related to nitrogen concentrations. [10], In addition to competing with native plants for nutrients, Cynodon dactylon presents a direct threat to agricultural crops and possibly to natural vegetation by acting as an alternate host to eleven arthropods, twelve nematodes and numerous viruses.[9][41]. Spreads with runners, is slightly more frost tolerant. Herbage Abstracts 31:255-260. Foliage is gray-green to bluish green and forms dense mats. Active Growth Period. Nitrogen fertilizers decrease the amount of carbohydrate reserves; clipping increases the translocation of nitrogen from the soil to the roots and carbohydrate reserves are depleted during the above-ground utilization of nitrogen. Tall Timbers Fire Ecology Conference 13:399-419. [27][28] Light textured soils mixed for four months with extracts from decaying Bermuda grass plants caused an inhibition of radicle elongation in barley and mustard seedlings. 1b. In September while the plants where in full bloom, one week before spraying 2% glyphosate from a boom-sprayer, the field was irrigate to encourage growth. [8] A rapidly growing variety, which can grow over hedges 2 m tall, was introduced to Hawaii and Arizona in the early 1900s. Cynodon dactylon (dubo) Economic importance: Food: Oryza sativa, Zea mays, Triticum aestivum, Hordeum vulgare, Sorghum vulgare Eleusine coracana are used as food for mankind. The distinguishing characteristics of Cynodon dactylon are the conspicuous ring of white hairs of the ligule, the fringe of hairs on the keel of the lemma, and the gray-green appearance of the foliage. [23] An increase in nitrogen from 0 to 80 kg/ha results in a 5 times greater above-ground biomass.[24]. As already stated, the control technique employed is dependent on the site parameters. RESPONSE TO MANIPULATIONS AND ABIOTIC FACTORS: Harlan, J. Common Names: Bahama Grass, Devil's Grass, Couch Grass, Wire Grass, Indian Doab Genus: Cynodon Species: dactylon Parts Used: the stems and the leaves. Crop Science 3:5-9. 1681 pp + supplement. [8] Average daily temperatures above 24° C are necessary for substantial growth and temperatures of 38° C result in maximum growth rates. comm.). BERMUDA GRASS- Cynodon dactylon DESCRIPTION: A wiry, spreading perennial which reproduces by seeds, but mostly by means of long runners on top of the ground. Removal of the aerial portion of perennial plants may slow the growth by limiting the accumulation of carbohydrates. [30] However, the average area increase for Cynodon dactylon is only 0.9 m2 per month. Florico Puerto Rican stargrass 54 . [30] Above ground growth is limited by temperatures below 18° C, and dies at -2° C.[18] The high temperature requirements explain the five times greater increase in sod area for June through November than for December through May. In this study, the antimicrobial activity of the plant crude extract. The second year of growth results in a drastic increase in the number of inflorescences with the maximum of 1125 per plant and an average of 87 inflorescences per square meter of sod.[30]. It grows in all types of soils , except in acids (pH between 4 and 6). Bermuda grass ( Cynodon dactylon Pers.) Various schedules of mowing, grazing, tilling, desiccating and herbicide applications should be studied at different locations. Univ. 1986a. Rhizomes are the primary over-wintering structure. [46][47] Glyphosate, sprayed from helicopters, trailer sprayers or backpack sprayers, at a concentration of 2% will result in an 85% to 95% control after the first year (Hamilton pers. Handbook of Energy Crops Purdue University, http://wiki.bugwood.org/index.php?title=Cynodon_dactylon&oldid=52002, Center for Invasive Species and Ecosystem Health at the University of Georgia. If closely mow [3] Small actively growing rhizome and stolon fragments are susceptible to drying within one week. Information on controlling Bermuda grass in a natural setting is needed. 1085 pp. The temperature, precipitation, humidity and elevation will determine the optimal control technique. SPECIES: Cynodon dactylon GENERAL BOTANICAL CHARACTERISTICS: Bermudagrass is an introduced, perennial, mat-forming, warm season grass. [33], The effects of fire on Cynodon dactylon are variable and dependent on the season and prevailing environmental conditions at the time of burning. giant Bermudagrass 53 . Four feet by four feet shade mats (mulch) were placed around the trees to reduce the sprouting of the remaining rhizomes. It is also used for cut-and-carry, hay and deferred feed. McKell, C. M., B. In addition to the allelopathic effects of Cynodon dactylon is the direct competition for space and nutrients by this rapidly growing perennial grass. Agronomy Journal 58:523-525. The subterranean dry weight averages 0.6 kg per m3 of soil within a 1 m radius from the center of the plant. [5][7], Warm temperatures are necessary for the plants to thrive, and long periods of freezing weather or short durations of extremely low temperatures are detrimental to the plants. 355 pp. Elongation of the internodes on the shoot is followed by the development of up to twenty buds per node. Johnsongrass- two decades of progress in control. Cynodon dactylon. [18] Young rhizomes sprout much more readily than do older ones. Effect of temperature, light, and nitrogen on growth and metabolism of 'tifgreen' Bermudagrass. Hart, R., R. Hughes, C. Lewis, and W. Monson. Table 3.5 Morphological characteristics measured in spaced plant (experiments 1 to 5) and sward (experiment) experiments comparing Cynodon dactylon varieties at DAFF Redlands Research Facility between 2002 and 2004. [17], The principle means of propagation of Cynodon dactylon is through the rhizomes and stolons. var. Soil. Low density mono-culture plots of Cynodon dactylon promoted early vegetative spreading growth with delayed reproductive development, whereas in high density plots the period of vegetative growth was shortened and floral development was hastened. Fire Effects Information System, U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station, Fire Sciences Laboratory, Global Invasive Species Database. Tolerates the shade very badly, to ... Irrigation. 1985. Desmodium aparines) 1951 (with supplement in 1960). Submergence of fragments for eight days in running water or four weeks in stagnant water had no effect on sprouting ability. Yearly summer monitoring of Bermuda grass should determine whether the aerial extent is diminishing with the employed control measure. The following people "eyeball" the distribution of the grass: No specific research on Bermuda grass control in natural plant communities is being conducted presently. Controlled burning at various times of the year and assorted repetition cycles from single burns to yearly repeated burns should be analyzed (Cox pers. dactylon (from here on referred to by the species name), which have spread to other countries. Effect of temperature, daylength, and solar radiation on production of coastal Bermudagrass. 1966. Horowitz, M. 1972d. common Bermudagrass 53 . The date of the initial introduction of Bermuda grass into the United States is uncertain, but most likely it occurred in the mid-1800s. Box 1440, San Antonio, TX 78295-1440; (512) 224-8774. [42] The temperature, moisture and clipping frequency influence the amount of subsequent growth. Bloat. Bermudagrass does not survive harsh winters and is difficult to maintain as a turfgrass in extreme northern areas. [26] Actively growing stolons are more susceptible to desiccation than post-dormant stolons. Wilcut, J., B. Truelove, D. Davis, and J. Williams. Hand weeding and spot herbicide treatment continued for the following year. [1][3] Most of these species originated and have remained in southeast Africa. Competitive interactions between, Ramakrishnan, P., and S. Kumar. [21][24] Care must be taken to remove all aerial growth repeatedly throughout the growing season when clipping and mowing are used as a control measure. 1950. p.1. The dormant rhizome buds at the basal node of the primary shoot begin to grow at the commencement of the wet warm season. The genetics, life-cycle, environmental requirements, phenology, beneficial and deleterious characteristics, and control of Bermuda grass are all well documented. 522 pp. The effect of nitrogen rate and clipping frequency upon the yield, protein content, and certain morphological characteristics of coastal Bermudagrass (. Desmodium heterophyllum . 1977. 159pp. [15] Half the amount of rhizome and root growth occurred in the 64% shade treated-plants than in the control plants. [17] Removal of greater than 40% of the shoots reduced root growth and many roots failed to resume growth when severely clipped. [11], Shading drastically affects both above- and below-ground growth. Repeated plowing throughout the summer growing period will fragment the rhizomes and bring them to the surface; this will aid in the desiccation of the rhizomes and stolons. After two years of competition Johnson grass reduced the yield of Bermuda grass by 99%. Siskiyou. United States Government Printing Office, Washington. [30] This growth pattern ensures both rapid spreading and strong establishment of the plants. [28] Incubation of test plants for two months with Bermuda grass results in a high degree of inhibition. The competitive ability of Cynodon dactylon depends on the competing plant species and the nutritional level of the soil. Effect of supplemental irrigation on the yield of coastal Bermudagrass in the southeastern United States. Kearney, T.H., and R.H. Peebles. McBee, G., and E. Holt. Most of the lateral growth, produced in concentric circles from the original rhizome, occurs throughout the summer (Horowitz 1972b,). In the spring when the temperature begins to increase new stolons elongate and aerial shoots sprout[30]. Greater than 48 hours of drying over an ammonium chloride solution kills actively growing stolons, whereas greater than 96 hours is required to destroy post-dormant fragments. comm.). In optimum conditions, it will form a dense lawn which tolerates foot traffic well and excludes many common weeds. [5][6][3] Although widespread, this species "thrives only under extreme disturbance and does not invade natural grasslands or forest vegetation". [18], New stolons are formed at the basal node of shoots which had developed from over-wintering rhizomes. The tiny seeds remain viable after passing through livestock and after submergence in water for 50 days. Click below on a thumbnail map or name for subspecies profiles. Trees were planted later, placed on a drip irrigation system and fertilized. Inconsistent results have been obtained on the effects of burning as a control for Bermuda grass. [25] The critical moisture level for stolons is 39% and for the harder to control rhizomes 15%. [30], Roots develop from rhizomes and stolons. Van Nostrand Reinhold Co., New York. California grasslands and range forage grasses. [23] Monthly clipping of Bermuda grass reduced the amount of regrowth in the following year, whereas bi-weekly clipping from spring through winter resulted in the complete inhibition of regrowth the following year. Bermuda grass poses no problem in undisturbed, cold and shady areas. Show All Characteristics. Friedman, T., and M. Horowitz. Cynodon dactylon is a warm-season, prostrate, perennial grass; it spreads by scaly rhizomes and flat stolons to form a dense resilient turf. [43][44] The removal of aerial portions of the plant as a control measure is only efficient on small scale problem sites due to the labor and time intensity of the necessary frequent repeated clippings. Geographic subdivisions for Cynodon dactylon: CA (exc MP) MAP CONTROLS 1. Burmudagrass. Revegetation of artificial disturbances in grasslands of the Serengeti National Park, Tanzania; colonization of grazed and ungrazed plots. Herbage Abstract 40:233-238.
