Available in PDF, EPUB and Kindle. Book excerpt: This document consists of three separate but related papers. The objective of the first is to improve managerial understanding of the impact of spring hunting by indigenous peoples in northern Canada. It is an analysis of the relative impact of hunting in the spring, compared with the conventional hunting seasons in fall and winter. In the second paper, Cooke et al. comments on the model and the choice of parameters that was used in a paper by Rockwell et al., and which provided the underpinning for the argument in that paper that a great increase in the hunting kill of Snow Geese was required to reverse the rapid increase in the numbers of those geese. In the third paper, Rockwell and Ankney counter Cooke's claims.

This book was released on 1994 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Northern Highlands of Mexico is an increasingly important wintering area for populations of Lesser Snow Geese and Ross" Geese that nest in the Western and Central Canadian Arctic. In Mexico, the growing importance of the Northern Highlands as a wintering area for Ross" Geese and the western Central Flyway population of Lesser Snow Geese underscored the need to conduct field observations in that area and prompted the development of a joint effort involving the Mexican Secretaria de Desarrolla Social, the U.S. Fish and Wildlife Service, and the Canadian Wildlife Service. Some of the objectives were: estimate the number of white geese on the principal wintering areas in the states of Durango and Chihuahua, determine the breeding ground origin of Lesser Snow Goose stocks overwinterin in Mexico, determint ehe incidence and number of Ross' Geese among flocks of white geese, assess the quality and security of white goose wintering habitat, and identify wetland habitats of critical importance to waterfowl.

Download or read book The Implications of Agriculture in Interior Alaska for Population Dynamics of Canada Geese branta Canadensis written by Michael William Eichholz and published by . This book was released on 2001 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Understanding how environmental change affects demography is essential for understanding and managing populations. An anthropogenic change in the environment that has affected wildlife populations is widespread agricultural development. Agriculture has both negatively and positively impacted abundance of species by affecting a variety of vital rates that influence population abundance. In this study, I describe the migration ecology of Canada geese (Branta Canadensis) that nest and stage in Interior Alaska. I also describe how the introduction of agriculture has potentially positively impacted population dynamics of Canada geese by increasing nutrient acquisition, thereby improving their fecundity and survival. Two subspecies of Canada geese used Interior Alaska for staging and at least partially segregated themselves during spring and fall staging. I documented a difference in survival between two age classes of Canada geese, primarily lesser Canada geese (B. c. parvipes), and attributed it to the higher susceptibility to harvest of hatch-year (HY) geese. Estimates of annual survival of Canada geese in this study are among the lowest, and estimates of recovery rates are among the highest, for a migratory population of geese, likely due to behavioral traits and habitat selection that make lesser Canada geese more susceptible to harvest. Survival of after-hatch-year (AHY) female Canada geese was positively associated with the amount of endogenous nutrient reserves females had at the time of banding in fall. An experimental manipulation of nutrient reserves, however, suggested that the association between nutrient reserves and survival results from variation in individual quality (not measured), not a direct relationship between nutrient reserves and survival. Female geese in our study gained fat and minerals, but not protein, during spring staging. Fall staging geese had fat levels greater than or equal to spring staging geese, suggesting fat reserves are important during early fall staging in this population of geese. Although I concluded that the introduction of agriculture has likely increased fecundity and decreased natural mortality in Canada geese that stage and breed in Interior Alaska, I also concluded that mortality due to harvest is sufficient to offset those changes, preventing an increase in the population"--Leaves iii-iv

Download or read book Surveys of Nesting Mid continent Lesser Snow Geese and Ross s Geese in Eastern and Central Arctic Canada 1997 98 written by R. H. Kerbes and published by Saskatoon : Canadian Wildlife Service. This book was released on 2006-01-01 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes & presents results of 1997-98 aerial surveys conducted to obtain estimates of the number & distribution of nesting snow geese (Chen caerulescens caerulescens) in the eastern & central Arctic and of nesting Ross's geese (Chen rossii) in the central Arctic & in the eastern Arctic at McConnell River. The surveys focussed on one population component, the nesting adults in June, and did not attempt to estimate numbers of non-breeders, failed breeders, young of the year, or total population size. Results are discussed in relation to historical changes in numbers & distribution of midcontinent snow geese & Ross's geese, photo surveys for monitoring population trends, and the recent & future use of periodic photographic surveys for international management of these goose populations.
Download or read book Recent Approaches to Canada Goose Management written by Harvey K. Nelson and published by . This book was released on 1962 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the past 15 years considerable attention has been focused on research and management problems associated with the Mississippi Valley population of Canada Geese. The general breeding, migration, and wintering ranges are well defined. Because this flock is closely associated with national wildlife refuges and State management areas in Wisconsin, Michigan, Ohio, Indiana, and Illinois, and the majority of this population winters in southern Illinois and vicinity, it has been possible to determine quite accurately annual total population trends, annual harvest rates, and the breeding potential of the population sent back to the breeding grounds each spring. Based on knowledge accumulated for this population, steps are being taken to compile similar information for other major continental Canada goose populations.
