Best Management Practices For Aquatic Vegetation Management In Lakes, Joseph E. Morris, Richard D. Clayton
Best Management Practices For Aquatic Vegetation Management In Lakes, Joseph E. Morris, Richard D. Clayton
11th Triennial National Wildlife and Fisheries Extension Specialists Conference (2006)
Aquatic plants are an important component of well functioning lake ecosystems. Plant abundance is influenced by sediments, nutrients and water clarity. Given the dominance of agriculture in Iowa, nutrients and soil lost from “leaky” watersheds combine to create ideal habitat for growth of aquatic plants in lakes and ponds and hasten eutrophication. Under these conditions, plant growth can become a nuisance and reduce recreation, especially shoreline angling and boating. These nuisance growths present special problems to lake managers and those interested in lake-based recreation. Given the complexity of the aquatic vegetation often found in lakes, there is no one long-term …

Breaking Through The Food Plot Mentality, Christopher E. Moorman, Craig A. Harper, Christopher Deperno
11th Triennial National Wildlife and Fisheries Extension Specialists Conference (2006)
Landowners and other wildlife enthusiasts often desire instant gratification when attempting to attract wildlife to their properties. Advertisements distributed by television programs, outdoor publications, and conservation organizations have played a large part in creating the desire for a quick and easy fix. Landowners are erroneously led to believe food plots or plantings of nonnative shrubs and trees will raise the carrying capacity for target wildlife species, even though the typical privately-held property contains overstocked, high-graded timber, intensively maintained croplands, mowed roadsides and drainage ditches, fire-suppressed woodlands, and pastures vegetated with non-native grasses that provide no cover and poor-quality forage. In …
Managing Kentucky Fee Fishing Operations, Forrest Wynne
Managing Kentucky Fee Fishing Operations, Forrest Wynne
11th Triennial National Wildlife and Fisheries Extension Specialists Conference (2006)
Management strategies for operating fee fishing operations in Kentucky are described. Recommendations are given for stocking rates of catfish, hybrid bream, and trout; aeration, pond depth and shape, supplemental feeding, and other management considerations. Marketing considerations discussed include pricing, and amenities such as restrooms, fish-cleaning services, and concessions including rental or sale of tackle and supplies.
Invasive Predators: A Synthesis Of The Past, Present, And Future, William C. Pitt, Gary W. Witmer
Invasive Predators: A Synthesis Of The Past, Present, And Future, William C. Pitt, Gary W. Witmer
USDA Wildlife Services: Staff Publications
Invasive predators have had devastating effects on species around the world and their effects are increasing. Successful invasive predators typically have a high reproductive rate, short generation times, a generalized diet, and are small or secretive. However, the probability of a successful invasion is also dependent on the qualities of the ecosystem invaded. Ecosystems with a limited assemblage of native species are the most susceptible to invasion provided that habitat and climate are favorable. In addition, the number of invasion opportunities for a species increases the likelihood that the species will successfully establish. The list of routes of entry or …
