PopulationThere are an estimated 7,000 to 11,200 wolves in Alaska and more than 5,000 in the lower 48 states.
Boy, like i said before, trying to have a conversation with you guys is like squeezing jello to hold onto it. You're all over the place. The OP was commenting about the irony of calling wolves endangered when there are so many in other places in North America. The second poster was basically calling the totals a lie because Alberta which is supposed to have 4,500 wolves is discussing culling 6,000 wolves to protect some caribou herds. So I went to the article which discusses this, right here on this site and I pointed out that this was over 5 years for starters so at 1,200 a year It's realistic in one sense that they will try to remove about 1/4 of the wolves per year. But I was pointing out that because of details, it may not be a realistic goal.And apparently some of you didn't like the fact that I pointed out that it was a habitat issue caused by man, also in the article. The article didn't say one word about wolves causing the problem that they were being killed for. At least the Canadians are honest in their science.If you have a point, I'm willing to listen and discuss it. If all you want to do is pile on because my opinion differs from yours or I notice things you don't pay attention to, I don't have the time or energy to respond. It's boring.
I do not find it any coincidence that wherever wolf numbers increase, big game herds suffer.The Truth About Wolves In Alaska"Testimony By Concerned Alaskans"http://graywolfnews.com/pdf/truth_about_wolves_in_alaska.pdfVan Ballenberghe (1985) states that wolf population regulation is needed when a caribou herd population declines and becomes trapped in a predator pit, wherein predators are able to prevent caribou populations from increasing. Because Canada has allowed wolves to multiply there are many caribou herds in trouble and close to extintion, wolves are a great part of the problem.http://graywolfnews.com/pdf/part_1_caribou_extinction_PNP.pdfhttp://graywolfnews.com/pdf/part_1_caribou_extinction_PNP.pdfhttp://graywolfnews.com/pdf/part_3_caribou_extinction_PNP.pdf
Wolf Interactions and Impacts in British ColumbiaDr. Tom Bergerud, University of British ColumbiaDr. Bergerud studied wolf interactions and impacts in a multi-ungulate system in British Columbia. Bergerud published a paper in the Journal of Wildlife Management in 1974, which stated that predation by wolves and bears is recognized as a major limiting factor on caribou and moose. If wolf numbers could be managed, game numbers would not decline. Without management, wolves will regulate the ungulates, with the biggest impact being on recruitment.
10.2 CARIBOU‐WOLF OVERLAP: MINIMIZING IMPACTS IN RISK AREASIdentifying areas of overlap between wolves and caribou is a key step to minimizing risks to caribou. Infact, risks might be higher for caribou when development results in more high quality wolf habitat inoverlap areas (forestry) or it increases wolf travel efficiency in such areas (e.g., by providing wolves withseismic lines as travel routes).Identification of high overlap areas could be potentially useful to mitigate effects of development byavoiding high overlap areas. Recent advances in RSF applications to predator‐prey theory confirms thatRSF models can be used to estimate overlap using the product estimator of two independent RSF models(Kristan and Boarman 2003, Hebblewhite et al. 2005). Because wolf predation is primarily driven byspecies like moose, elk and deer in caribou systems (Hebblewhite et al. 2007), the assumption ofindependence seems reasonable for wolves and caribou.We treated RSF models for caribou and wolves as habitat ranking models, and used them to assesscaribou‐wolf overlap by subtracting inter‐species RSFs. Specifically, we subtracted the binned wolf RSFmodel from the binned caribou RSF model. This generated a caribou‐wolf overlap index from ‐10 to +10,7373 PTACT Final Reportwhere high values indicate high quality caribou habitat and low quality wolf habitat, and low valuesindicate low quality caribou habitat and high quality wolf habitat. We liken this index to a spatialprediction of caribou “safe zones” (Figures 10.1, 10.2), wherein high values are those likely to be bothpreferred by caribou and avoided by wolves.Our maps can be used by environmental managers, industry and other stakeholders. Decision makerswill evaluate the risk for caribou posed by human‐induced habitat alterations happening in areas with alow value for the “safe zones” index.10.3 FUTURE RESEARCH: SPATIAL POPULATION VIABILITY ANALYSISConservation of woodland caribou will depend on our ability to effectively monitor population trendsand population dynamics (and the mechanisms acting upon them) within and among subpopulationsacross the species range. We are using existing monitoring data collected in Alberta to assess therelationships between vital rates and population growth to provide a case study for using spatiallyexplicitpopulation viability analyses in guiding conservation efforts. This analysis is ongoing, anddiscussion herein preliminary.We are using spatially‐explicit population viability analysis (PVA) techniques to assess: 1) the relationshipbetween vital rates (adult survival and recruitment) and population growth, 2) the power in our ability tomonitor trends or changes in population growth rates using estimates of these vital rates from currentlyestablished protocols, 3) the effects of misclassification errors in calf‐cow ratio data, and 4) the longtermviability of woodland caribou in Alberta as a case‐study in using spatially‐explicit PVAs to predictchanges in meta‐population dynamics. We are also considering threats and population growth ratesspecific to each local population.Preliminary results include a literature review of over 40 woodland caribou populations and studies todevelop a population model to assess the relationship between adult and calf survival rates andpopulation growth rate (Figure 10.3).
look at how hard coyotes are on deer? i could look it up and get some straight accurate number but i thought that about of the 70% of fawns that dont make it like 40 to 50% of those deaths are from coyotes, just think of what wolves will do??
Quotelook at how hard coyotes are on deer? i could look it up and get some straight accurate number but i thought that about of the 70% of fawns that dont make it like 40 to 50% of those deaths are from coyotes, just think of what wolves will do??and, we hunt them 24/7/365 LITERALLY and look where their population is at. I believe we have already reached a pivitol population density where if we hunted them the same as coyotes, we couldn't control them, yet we are trying to protect them. Can anyone suggest a reason why deer are in town or on your porch?

I think its good to see both views. Its a great way to learn. It also generally is what makes "us" different. Many and I mean MANY of the hugger kind would NEVER open their minds up to hearing someone elses opinion. Thats the difference between true outdoorsman and radicals. Most outdoorsman are actually conservationists. MANY and again I mean MANY "huggers" are very far from being conservationists although thats what they claim to be. Many have no clue about what really occurs in nature. As long as its not abrasive then I am sure it will be tolerated. In fact the more that you can convey the message, the more hope there is.
