Knowledge of the relationship between waterfowl hunters and harvest levels may better inform harvest management decisions. We examined frequency of different sizes of daily harvests among duck hunters, and hunters’ contributions to duck harvest in the Central Flyway from 1975–1984, 1988–1993, and 2002–2011 using the U.S. Fish and Wildlife Service’s Parts Collection Survey. We stratified hunters...

The retention of trees in harvest units is an integral part of forest management practices on federal lands in the northwestern United States (U.S.), yet the ecological benefits that result from various levels or patterns of retained trees remain speculative. Large-scale and long-term silvicultural experiments are needed to evaluate the effects of alternative forest management strategies on bio...

G the harvest represents a complex managerial problem for agricultural cooperatives involved in harvesting and processing operations: balancing the risk of overinvestment with the risk of underproduction. The rate to harvest crops and the corresponding capital investment are critical strategic decisions in situations where poor weather conditions present a risk of crop loss. In this article, we...

Sylvén, S. 2003. Management and regulated harvest of moose (Alces alces) in Sweden. Moose management has contributed to the large changes in the Swedish moose population during the last decades. Simulation experiments and monitoring of population parameters are two tools in the management system studied in this thesis. They can be used to increase the understanding of effects of different harve...

The profitability of managing loblolly pine (Pinus taeda L.) on nonindustrial private forest lands in East Texas depends on the frequency, timing and intensity of commercial thinning(s), and the timing of the final harvest. The landowner's alternative rate of return (ARR), stumpage prices, labor costs, and management practices also have an effect on profitability. To determine the best manageme...

Few studies have evaluated the rate of infection or mode of transmission for wildlife diseases, and the implications of alternative management strategies. We used hunter harvest data from 2002 to 2013 to investigate chronic wasting disease (CWD) infection rate and transmission modes, and address how alternative management approaches affect disease dynamics in a Wisconsin white-tailed deer popul...

A wide variety of modelling approaches have been developed over the past few decades to provide quantitative advice to fishery managers about the potential consequences of proposed alternative management actions and to improve the design of fisherymanagement systems. This article surveys these approaches to identify the main differences among them in their application of decision theory, partic...

Invasive and overabundant species are an increasing threat to biodiversity and ecosystem functioning world-wide. As such, large amounts of money are spent each year on attempts to control them. These efforts can, however, be thwarted if exploitation is compensated demographically or if populations simply become too numerous for management to elicit an effective and rapid functional response. We...

Strategies to mitigate carbon dioxide emissions through forestry activities have been proposed, but ecosystem process-based integration of climate change, enhanced CO2, disturbance from fire, and management actions at regional scales are extremely limited. Here, we examine the relative merits of afforestation, reforestation, management changes, and harvest residue bioenergy use in the Pacific N...
