Estimating survival of radio-tagged birds
C.M. Bunck, K. H. Pollock
J.-D. Lebreton, P.M. North, editor(s)
1993, Book chapter, Marked Individuals in the Study of Bird Population
Parametric and nonparametric methods for estimating survival of radio-tagged birds are described. The general assumptions of these methods are reviewed. An estimate based on the assumption of constant survival throughout the period is emphasized in the overview of parametric methods. Two nonparametric methods, the Kaplan-Meier estimate of the survival funcrion...

Monitoring neotropical migrants on managed land: When, where, why
Sam Droege
D.M. Finch, P.W. Stangel, editor(s)
1993, Book chapter, Status and Management of Neotropical Migratory Birds
Relevant wildlife monitoring on managed lands lies somewhere between monitoring everything and monitoring nothing. Knowing the population status of all birds on a managed area would be potentially useful information but would be costly to collect, but without monitoring no link between management and wildlife populations can be made. A...
Overview of national bird population monitoring programs and databases
G.S. Butcher, B. Peterjohn, C.J. Ralph
Deborah M. Finch, Peter W. Stangel, editor(s)
1993, Book chapter, Status and Management of Neotropical Migratory Birds. Estes Park Center, September 21-25, YMCA of the Rockies, Colorado
A number of programs have been set up to monitor populations of nongame migratory birds. We review these programs and their purposes and provide information on obtaining data or results from these programs. In addition, we review recommendations for improving these programs....

Species richness and relative abundance of breeding birds in forests of the Mississippi Alluvial Valley
C.O. Nelms, D.J. Twedt
Winston Paul Smith, editor(s)
1993, Book chapter, Fourth meeting of the Southeast Management Working Group Partners in Flight
In 1992, the Vicksburg Field Research Station of the National Wetlands Research Center initiated research on the ecology of migratory birds within forests of the Mississippi Alluvial Valley (MAV). The MAV was historically a nearly contiguous bottomland hardwood forest, however, only remnants remain. These remnants are fragmented and often influenced...

Point counts of landbirds in bottomland hardwood forests of the Mississippi Alluvial Valley: How long and how many?
W.P. Smith, D.A. Wiedenfeld, P.B. Hanel, D.J. Twedt, R.P. Ford, R.J. Cooper
Winston Paul Smith, editor(s)
1993, Book chapter, Fourth meeting of the Southeast Management Working Group Partners in Flight
To quantify efficacy of point count sampling in bottomland hardwood forests, we examined the influence of point count duration on corresponding estimates of number of individuals and species recorded. To accomplish this we conducted a totalof 82 point counts 7 May-16 May 1992distributed among three habitats (Wet, Mesic, Dry) in...
Sampling bird communities in bottomland hardwood forests of the Mississippi Alluvial Valley: Number of points visited versus number of visits to a point
D.J. Twedt, W.P. Smith, R.J. Cooper, R.P. Ford, P.B. Hamel, D.A. Wiedenfeld
Winston Paul Smith, editor(s)
1993, Book chapter, Fourth meeting of the Southeast Management Working Group Partners in Flight
Within each of 4 forest stands on Delta Experimental Forest (DEF), 25 points were visited 5 to 7 times from 8 May to 21 May 1991, and 6 times from 30 May to 12 June 1992. During each visit to a point, all birds detected, visuallyor aurally, at any distance...
Trail inventory and assessment approaches to trail system planning at Delaware Water Gap National Recreation Area
P.B. Williams, J. L. Marion
Gail A. Vander Stoep, editor(s)
1993, Book chapter, Proceedings of the 1992 Northeastern Recreation Research Symposium. April 5-7, 1992, State Parks Management and Research Institute, Saratoga Springs, NY
Trail system planning and management require accurate assessments of existing trail resources and their condition. A standardized and efficient process for surveying, inventorying, and assessing trail systems was developed and applied in the Delaware Water Gap National Recreation Area. Two approaches employed were (1) a Trail System Inventory,...

Campsite impact management: A survey of National Park Service backcountry managers
J. L. Marion, C.J. Stubbs
Gail A. Vander Stoep, editor(s)
1993, Book chapter, Proceedings of the 1992 Northeastern Recreation Research Symposium. April 5-7, 1992, State Parks Management and Research Institute, Saratoga Springs, NY
Though a central purpose for the creation and management of parks, visitation inevitably affects the natural resources of parks. This is particularly true at campsites, where visitation and its effects are concentrated. This paper presents partial results from a survey of National Park Service managers regarding general strategies...
