Attitudes And Behaviors Of Iowa Farmers Toward Wildlife , James L. Pease Jan 1992

Attitudes And Behaviors Of Iowa Farmers Toward Wildlife , James L. Pease

Retrospective Theses and Dissertations

This research examines the attitudes and behaviors of Iowa farmers toward wildlife. Based on a 1991 statewide mailed survey of 822 farmers, it divides Iowa farmers into "wildlife-oriented" and "non-wildlife-oriented" groups for sampling and analysis. It identifies demographic and personal factors that are correlated with a wildlife orientation. Wildlife-oriented farmers in Iowa tend to be farmers with smaller acreages overall, with smaller gross farm incomes, with fewer acres devoted to row-crops, and with more diverse landscapes that more often include trees, streams, Conservation Reserve Program acres or other non-agricultural land than farmers who are not wildlife-oriented. Wildlife-oriented farmers also engage ...


Species Richness And Nest Productivity Of Marsh Birds On Restored Prairie Potholes In Northern Iowa , Lisa Marie Hemesath Jan 1991

Species Richness And Nest Productivity Of Marsh Birds On Restored Prairie Potholes In Northern Iowa , Lisa Marie Hemesath

Retrospective Theses and Dissertations

Since the mid 1800s the number of wetlands in Iowa has decreased by 95% (Bishop 1981). Wetland drainage and the conversion of native grasslands into croplands have been primary causes of this loss. Because of this habitat loss, several wetland species have been extirpated from the state, and others have small populations (Weller 1979, Dinsmore 1981). The 1985 Farm Bill and the North American Waterfowl Management Plan provided the stimulus for wetland restoration on many of these drained basins. My objectives were to 1) determine if certain wetland characteristics affected bird colonization on restored wetlands and 2) assess the habitat ...

Effects Of Prescribed Burning On Avian Foraging Ecology And Arthropod Abundance In Sagebrush-Grassland , Brian Mark Winter Jan 1984

Effects Of Prescribed Burning On Avian Foraging Ecology And Arthropod Abundance In Sagebrush-Grassland , Brian Mark Winter

Retrospective Theses and Dissertations

Prescribed burning in western sagebrush-grasslands has been used primarily to eradicate sagebrush (Artemisia spp.) and, consequently, increase the growth of herbaceous vegetation. Although fire has been used commonly, little is known about its effects on nongame birds breeding in sagebrush-grasslands. Furthermore, the effects of sagebrush removal on arthropod abundance and composition are unknown. To assess the effect of prescribed burning on the foraging ecology of sage and Brewer's sparrows, intensive preburn and postburn data were collected. My objectives were: (1) to document effects of prescribed burning on the general feeding behavior, activity budgets, feeding frequency, and foraging patterns of ...


Gray Partridge Habitat Use And Nesting Biology In North-Central Iowa , Vernon Pat Mccrow Jan 1982

Gray Partridge Habitat Use And Nesting Biology In North-Central Iowa , Vernon Pat Mccrow

Retrospective Theses and Dissertations

Gray partridge (Perdix perdix) movements, habitat use, and nesting were studied from 1975 to 1977 in north-central Iowa, a region of intensive row-crop agriculture. Use of 4 habitat classes by 9 birds monitored by radio telemetry was compared with habitat availability over 4 seasonal periods. Strip cover was used at higher than expected frequencies in all periods. Partridge utilized the periphery of fields at a relatively high frequency while use of the central portion was less than expected. Three partridge broods utilized soybeans at a high frequency and corn at a relatively low frequency through the 1st 4 weeks of ...

The Anti-Hunting Movement--The People Involved, Their Attitude Development, And Implications For Wildlife Management , Alice Wywialowski Jan 1977

The Anti-Hunting Movement--The People Involved, Their Attitude Development, And Implications For Wildlife Management , Alice Wywialowski

Retrospective Theses and Dissertations

Hunting in the United States has been assumed to be a right of the people (Cain 1962). Recently, more people have begun to challenge that assumption (Trainer 1976) as well as the desirability of hunting as a sport. Public sentiment against hunting has increased in the past few years (Applegate 1975). The main objectives of this study are to explain the formation of anti-hunting attitudes and their implications for wildlife management.
