"This book tells the recent story of Iowa's wildlife from recovery and restoration to disappointing declines. During the pandemic, the number of visitors to state parks, wildlife areas, and other natural areas has increased greatly. For many, this is a new experience. This book will provide them with a reliable source of information about many of the animals that they are now seeing. Much has changed with Iowa's wildlife in the past 30 years. Some species like Canada goose, wild turkey, and white-tailed deer that once were rare in Iowa are now common, and others like sandhill crane, river otter, and trumpeter swan are becoming increasingly abundant. The goal of this book is to provide an up-to-date, scientifically based summary of changes in the distribution, status, conservation needs, and future prospects of about 60 species of Iowa's birds and mammals whose populations have increased or decreased in the past 30 years. Emphasis is given to several species that have experienced significant growth, some that show signs that they may experience future growth, and a few whose long-term future in Iowa is in jeopardy. This book is not an update of James and Stephen Dinsmore's earlier book, A Country So Full of Game, which discussed Iowa's wildlife up to about 1990. This is an entirely new book, discussing what has happened in the years 1990-2020. For species covered in the earlier book, only a brief discussion of earlier years is provided to connect the new material to what happened earlier"--

Wildlife Demography compiles the multitude of available estimation techniques based on sex and age data, and presents these varying techniques in one organized, unified volume. Designed to guide researchers to the most appropriate estimator based upon their particular data set and the desired level of study precision, this book provides quantitative consideration, statistical models, estimator variance, assumptions and examples of use. The authors focus on estimation techniques using sex and age ratios because this data is relatively easy to collect and commonly used by wildlife management. - Applicable to a wide array of wildlife species, including game and non-game birds and mammals - Features more than 100 annotated examples illustrating application of statistical methods - Includes more than 640 references of the analysis of nontagging data and the factors that may influence interpretation - Derives historical and ad hoc demographic methods in a modern statistical framework

Harvest of Fish and Wildlife: New Paradigms for Sustainable Management unites experts in wildlife and fishery sciences for an interdisciplinary overview of harvest management. This book presents unique insights for embracing the complete social-ecological system to ensure a sustainable future. It educates users on evolutionary and population dynamics; social and political influences; hunter and angler behavior; decision processes; impacts of regulations; and stakeholder involvement. Features: Written by twenty-four teams of leading scientists and managers. Promotes transparent justification for fishing and hunting regulations. Provides examples for integrating decision making into management. Emphasizes creativity in management by integrating art and science. This book appeals to population biologists, evolutionary biologists and social scientists. It is a key resource for on-the-ground managers and research scientists developing harvesting applications. As the book’s contributors explain: “Making decisions that are robust to uncertainty...is a paradigm shift with a lot of potential to improve outcomes for fish and wildlife populations.” –Andrew Tyre and Brigitte Tenhumberg “Temporal shifts in system states...must somehow be anticipated and dealt with to derive harvest policies that remain optimal in the long term.” –Michael Conroy “Proactive, effective management of sportspersons...will be essential in the new paradigm of harvest management.” –Matthew Gruntorad and Christopher Chizinski
