More than 1.5 million traffic crashes involving deer occur each year in the U.S. These crashes produce $1.1 billion in vehicle damage & 150 fatalities annually. Deer-related crashes are increasing as both deer populations & vehicular travel increase. Many methods have been used in attempts to reduce deer crashes, often with little scientific foundation & limited evaluation. This paper summarizes the methods & reviews the evidence of their effectiveness & the situations in which each may be useful. The only widely accepted method with evidence of effectiveness is well-designed & maintained fencing, with underpasses or overpasses as appropriate. Other methods using advanced technology require substantial additional research & evaluation.

This toolbox contains what is believed to be the most detailed summary and evaluation of DVC countermeasure information. Three levels of discussion are provided that focus on the current state-of-the knowledge countermeasure related to 16 potential DVC countermeasures and specific findings and conclusions for each countermeasure are discussed.

The first book to summarise management objectives for ungulates across Europe.

This book considers a number of problems posed by ungulates and their management in Europe. Through a synthesis of the underlying biology and a comparison of the management techniques adopted in different countries, the book explores which management approaches seem effective - and in which circumstances. Experts in a number of different areas of applied wildlife biology review various management problems and alternative solutions, including the impact of large ungulates on agriculture, forestry and conservation habitats, the impact of disease and predation on ungulate populations and the involvement of ungulates in road traffic accidents and possible measures for mitigation. This book is directed at practising wildlife managers, those involved in research to improve methods of wildlife management, and policy-makers in local, regional and national administrations.

This report reviews 39 mitigation measures that reduce animal vehicle collisions and that provide habitat connectivity for wildlife across highways. The overview is restricted to mitigation measures aimed at large terrestrial mammals (deer size and larger). However, this report also includes information regarding how such measures may affect or benefit federally endangered or threatened species in Montana, regardless of their size. In addition to the detailed information for each mitigation measure, a summary table is provided that provides at a glance information on the costs and benefits of the individual mitigation measures for which such data were available. Furthermore, the report graphically illustrates which measures have the best monetary balance (the difference between benefits and costs) and which measures reduce animal vehicle collisions and associated costs best. Based on the results, the authors of this report identified wildlife fencing, with or without wildlife underpasses or a combination of wildlife underpasses and overpasses, and animal detection systems with wildlife fencing, as the most cost effective mitigation measures. Animal detection systems without wildlife fences or wildlife fences with a high density of wildlife overpasses are also cost effective, but more data on system effectiveness are needed before these systems are recommended for implementation rather than further study. The final section of the report provides suggestions on the implementation or study for each of the 39 mitigation measures.
