Reproductive control is more efficient than lethal control only for some rodent and small bird species with high reproductive rates and low survival rates. Population simulations using PM1 and PM2 demonstrated that for most vertebrate pest species considered, lethal control will be more efficient than reproductive control in reducing population levels. PM4 simulates population changes for a species at weekly intervals over an annual cycle, exploring the immediate (≤1 year) impact of population management actions. PM3 simulates population responses to actual management actions through 10-year intervals. PM1 and PM2 explore the relative efficacy of reproductive and lethal control for vertebrate species over 10-year intervals. Four population models (PM1 to PM4) for predicting population responses are described. Models are essential to project how populations will respond to proposed management actions, providing a scientific foundation to counter the emotional debates that often arise. To justify and defend lethal or reproductive control programs to solve vertebrate pest problems, wildlife biologists must have a sound understanding of the population status and dynamics of the problem species.
Opening Remarks – Vertebrate Pest Control. Twentieth Anniversary of Vertebrate Pest Conferences Opening Remarks - A Retrospective Look at the A History of the Vertebrate Pest Conference. It is the most widely-recognizedĭetailed histories of the development of this Conference are found in these publications: Planning committee formally became an incorporated non-profit entity inġ975, and the Vertebrate Pest Conference is now held in late winter orĮarly spring every two years. Which arranged and hosted the first "Vertebrate Pest ControlĬonference" held in Sacramento on February 6 & 7, 1962. Howard, became the Vertebrate Pest Control Technical Committee, To plan such a conference, the organizing group, chaired by Dr. Realized that having a conference would permit a Proceedings to be published, in which this information could be made widely available. Within in-house reports of the various agencies that were largely Participants recognized that few published documents on vertebrate pestĬontrol were available, as such information was typically contained of Public Health Īnd the Branch of Predator and Rodent Control, Bureau of Sport FisheriesĪnd Wildlife, U.S. University of California the California Dept. Originated in early 1960 from discussions among representatives of the The concept of the Vertebrate Pest Conference
