The Scientific LiteratureMorphometric Data and the Hunting LiteratureWith respect to scholarly morphometric study of extant bears we are fortunate in the available data. Why? Because, in many global regions inhabited by bears from the icy Arctic to the Americas and Eurasia there is strong governmental bear management policy in the areas of conservation where field technical (morphometric) data is collected along with the harvest management of bears where there is strong governmental regulation in the hunting of bears. In both areas of bear management scientists have been at the forefront of governmental policy which in some cases date back several decades. Dealing with the latter, the harvest management of bears, the morphometric data collected is qualitatively superior to the old hunting records and old hunting literature claims which are often filled with exaggerated or inaccurate information not accepted by the modern scientific literature whereas current reputable hunting sources for example the Boone & Crocket Club data are viewed as credible and are used by scientist for harvest analysis and included in the scientific literature.
About the literature  As I have said before, I am currently on extended travel and do not have access to a lot of my files and documents, however, I was able to find online (not to mention in earlier forum posts) references to B&CC in the scientific literature. I will share them shortly. I will also make a duplicate post in the "Hunting Organizations" thread. More to come....   Source: Black Bear.

Kodiak brown bear (cont)also....From the Kodiak National Wildlife Refuge web site, "Size range for females is from 400 to 700 pounds and for males 600 to 1,400 pounds. There can be a difference of 20 to 30 percent gain in weight between when they emerge from dens in the spring and when they den up in the late fall." www.fws.gov/refuge/Kodiak/wildlife_and_habitat/bear.htmlAs we examine the data in greater detail, we are better able to chart the growth and development between a young adult bear in comparison to the older mature adult bear. Material Extract "Skull size-age data collected as a result of the regulation changes clearly demonstrated that age structure of the male bear population has a direct impact on the number of large bears available to hunters. On Kodiak, over 90% of male bears have the potential to reach skull sizes exceeding 68 cm, and over half of the bears can attain trophy size if they live long enough. Therefore, when managing for a population that retains a segment of large males, it is important to establish regulations that consider survival rates of adult males as well as productive females. During this study, hunting regulations for Kodiak bears were crafted to distribute harvest throughout the archipelago and reduce hunter efficiency. While season dates included times when hide quality was at its peak, they are also set to afford protection to females that have longer denning periods. Prohibiting harvest of maternal females and their dependent cubs further protected productive females." Source: Van Daele, L.J. 2007.

Administrator Note: There is more follow up information that can be provided but has not been. After reviewing the provided literature sample, I think the readership better understands the dynamics of harvest management of bears and venerable hunting organizations such as B&CC and their value and influence in bear management. If interested, the readership is free to follow up more on this topic. Edit: Apologies, there was a mix up (misplacement) of two quoted text extracts which has now been corrected. |
