Effect of the Past Demand of Bobcat Pelts on Recent Years
Abstract: Precise and unbiased estimates of survival and mortality patterns are needed tounderstand population dynamics of bobcats (Lynx rufus). Bobcat pelts were at a highdemand 20 years ago. As a result, bobcat populations had to be monitored, even now, tomake sure that the decline of bobcat populations would not decrease again as it did in thepast. By using the Pop-2 computer model, we are able to predict what percentage of anincrease in harvest will effect the population and if it will crash. A 10% increase in harvestwill decrease the population at a stable rate while a 30% increase will crash theKey words: bobcat, Lynx rufus, Pop-2 model, harvest, crash Such as furs from other wild cats, the bobcat's fur contains beauty. As a result,bobcat pelts have been demanded by people in the past which caused an increase inharvest of the bobcat. The hunters searching for this creature saw this as an opportunityto make lots of money. But since then, in recent years, bobcat pelts have decreased inprice. This caused a decrease in the hunting of the bobcats. But during those times ofhigh harvest, wildlife agencies had to keep up to date on their population. Even now,
This was for the purpose of knowing thepopulation before the increase in harvest. In this study though, harvest was not a factor that was introduced. I repeated the same process but this time Iincreased harvest by 30%. Simulation modelincorporating both spatial and temporal attributes indicated that harvest rates of greaterthan 20% of the fall population would likely cause population declines, all else being equal(Knick 1990). ------------------------------------------------------------------------**Bibliography**Literature CitedBailey, T. They know that a harvest increasegreater than 20% can cause the bobcat population to seriously decline to very low levels;even cause a crash (Knick 1990). This is illustrated on the same chart. Discussion The end results with the increase in harvest was expected. Managers should consider the potential magnitude of harvest when implementingharvest limits on bobcat populations (Crowe 1975). Journal of Wildlife Management 42:292-296Heisey, D. The data can be seen on table 3 and table 3C. The increase in population is what wasexpected. Iprinted out the original population numbers labeled table 1 and table 1A before anychanges to the database had been made.
