|
 | The interior population of the Least Tern (Sternula antillarum) was added to the U.S. Fish and Wildlife Service (USFWS) list of threatened and endangered species in 1985 because of suspected low numbers and concerns about breeding season habitat loss or degradation on large interior rivers. Range-wide survey data were incomplete when Interior Least Terns (ILT) were originally listed. Although many ILT counts have been conducted over the past 20 years, ... |

|
 | The purpose of this technical note is to show how a probability tree can be used to structure consideration of uncertainties surrounding zebra mussel dispersal. Probability trees are diagrammatic tools often used as part of formal decision analysis (Clemens and Reilly 2001). This particular tree considers uncertainties about the spread of zebra mussels to Bayou Bartholomew in light of existing data and knowledge concerning the physiological ecology of the species. ... |

|
 | Fire is an important ecological process in the southern United States. Many animal and plant species evolved in the presence of fire, and many vegetation types thrive best in the presence of fire. Fire-dependent biota are declining, because of fire suppression and landscape changes. Pine Bluff Arsenal has been working to restore pine savanna, a declining habitat, by reintroducing prescribed burns on part of the Arsenal. The report contains information ... |

|
 | A survey for freshwater mussels (Family: Unionidae) was conducted in the Bayou Meto area (including Bayou Meto, Bayou Two Prairie, Crooked Creek, Indian Bayou, Salt Bayou Ditch, Wabbaseka Bayou, and associated miscellaneous ditches) near Stuttgart, AR, in the spring of 2001. Approximately 19 hr of search time was expended at 45 sites in the study area. A separate search of five sites on Plum Bayou was conducted on 18 September ... |

|
 | Previous to the establishment of the arsenal in 1941 the area was a mix of farms and forest. The area was cutover for timber before 1920. The flat areas were cultivated and steeper area used as woodlots and grazing for cattle and hogs. Abandoned fields grew up in pine or in some cases were planted in pine during the 1930's. The burning of farm stubble and woodlands ... |

|
 | A sedimentation and navigation study of the lower Mississippi River, between River Miles 603 and 596 was conducted to study and solve the navigation problems associated with the Mississippi River at White River Confluence. Problems exist when tows navigate in and out of the White River near River mile 599. The outside of Subgrass Bend creates a deep channel with high velocities at the confluence. Several ... |

|
 | The sediment transport function developed by Emmett M. Laursen was adopted for the Arkansas River navigation project because it expresses transport rate using terms that permit separating the effects of hydraulic and sediment parameters. However, in attempting to reproduce measured data from the lower Arkansas River, the Laursen function gave results that were systematically low. The same trend appeared when the function was applied to Missouri River data. Therefore, Laursen's ... |

|
 | Tests were conducted on a 1:36-scale model of Dam No. 2, Arkansas River, to determine a method to prevent additional scour upstream and downstream from the structure and protect these areas from Dow conditions resulting from gate misoperation, vandalism, debris passage, and navigation accidents. The model reproduced 600 ft of topography upstream from the dam, the entire spillway and stilling basin, the proposed scour protection material, and approximately a 1,200-ft ... |

|
 | An integrated program of geomorphological and archeological investigation was conducted within those portions of the McClellan-Kerr Arkansas River Navigation System between Dardanelle, Arkansas, and the Mississippi River. These included office, laboratory, and field studies. These investigations documented those landforms and landforming processes which could be identified at a reconnaissance level effort. The documented archeological record is discussed in terms of its distribution across the landscape. Recommendations for further investigations are ... |
