词条 | Rattlesnake round-up |
释义 |
Round-ups have economic and social importance to the communities that hold them.[1][4] The events often attract thousands of tourists, which can bring hundreds of thousands of dollars of revenue into small towns; the Sweetwater Round-Up's economic impact was estimated to exceed US$5 million in 2006.[5] Snake collectors often make large profits selling snakes at the events. Cash prizes and trophies are often given out to participants in categories like heaviest, longest, or most snakes.[3][4] These incentives result in all size classes of snakes being targeted equally.[3] Most roundups target the western diamondback rattlesnake (Crotalus atrox), though some events target prairie rattlesnakes (C. viridis), timber rattlesnakes (C. horridus), or the eastern diamondback rattlesnake (C. adamanteus).[3][6] A harvest of several hundred to several thousand kilograms of snakes is typical for many roundups. In Texas, up to 125,000 snakes could have been removed annually from the wild during the 1990s.[4] However, effects of roundups on rattlesnake populations are unclear. Harvest size at roundups is highly variable from year to year but does not show a consistent downward trend, even after decades of annual roundup events in some areas.[4] C. atrox is listed as Least Concern by the IUCN.[7] However, poaching and roundups have been destructive to populations of timber rattlesnakes (C. horridus) in the northeastern United States.[4] Some groups are concerned that C. atrox local populations may be declining rapidly, even if the global population is unaffected.[3][19] Rattlesnake round-ups became a concern by animal welfare groups and conservationists due to claims of animal cruelty and excessive threat of future endangerment.[3][8][9] In response, some Round-Ups impose catch size restrictions or releasing captured snakes back into the wild.[2][10] References1. ^1 Means, B. 2009.
