Available in PDF, EPUB and Kindle. Book excerpt: Monitoring moose (Alces alces) populations is a key component of wildlife management in Alaska. In response to reports of recent difficulties implementing the existing techniques for monitoring moose, an interagency work group identified the monitoring techniques currently in use, characterized technique performance, and examined commonality and geographic patterns of problems encountered when applying techniques in the field. Field biologists engaged in monitoring moose in Alaska were emailed an online questionnaire designed to organize information about overall program satisfaction, population parameters monitored, techniques for estimating parameters, and current impediments to monitoring. During 2007-2017, biologists failed to complete 42% of scheduled surveys to estimate abundance (n = 295 surveys, 42 respondents). Survey failure rates differed across ecoregions: failure rates were highest in the Kenai/Southcentral (57%), Eastern Interior (43%) and Coastal Subarctic (41%) ecoregions, but lower rates of survey failure were reported for Western Interior (20%) and Arctic Slope (15%) ecoregions of Alaska. Patterns of survey failure were similar for composition. Lack of adequate snow cover and poor flying weather were the first and second most commonly cited reasons, respectively, for failure to complete scheduled surveys. Where surveys were successfully completed, estimates generally had less precision than desired, with only 50% of respondents achieving intended precision goals for abundance estimation. Biologists indicated a strong willingness to use a new method for monitoring moose if it 1) did not rely on complete snow cover, 2) was more accurate, 3) provided higher precision, 4) provided continuity with previous estimates, 5) could be used where inclement flying weather is frequent, 6) could be used in areas with dense vegetative cover, 7) was accompanied by technical assistance or a user manual, and 6) was similar in cost to existing methods. They indicated mild unwillingness to use a new method that 1) used ground observations, 2) required hunters to turn in specimens, 3) used helicopters for aerial observation, or 4) required more resources than current methods. These results highlight the need to develop new survey and measurement techniques that can be conducted independently of problematic snow and weather conditions, or at least have far more flexibility in implementing survey protocols. Indeed, the problem of monitoring moose in areas with poor snow conditions is so challenging and pervasive that solutions may require a concentrated, cooperative effort among agencies, including practical feedback from field biologists. Precision of existing techniques may also be improved through better optimization of survey design, the integration of more historical population information in estimation, and perhaps by better clarifying precision requirements relative to program goals.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Moose (Alces alces) aerial surveys provide the information needed for effective management only when they are accurate and precise. I aimed to identify gaps in and improve understanding of aerial moose surveys in North America by comparing survey techniques and exploring an application of thermal camera technology. Current aerial moose survey methods are compared in a jurisdictional review, including approaches to correcting visibility bias and a discussion of implementation of new technological advancements. Stratified random block (SRB) surveys are the most common, alongside distance sampling (DS) and other survey types. Thermal imagery, Geographic Information Systems (GIS), and Global Positioning Systems (GPS) have been implemented into survey designs to improve the accuracy of estimates or logistics of the survey. Using a virtual population of moose derived from Newfoundland aerial moose survey observations, a simulation of SRB and two DS surveys is used to compare accuracy, precision, and effort of each survey type. DS survey transects are spaced 1000- and 5559-m apart, and both survey types are sampled at high (~3 moose/km2) and medium (~1 moose/km2) densities. Accuracy is used as the bias in the simulation and statistically significant differences in precision and effort occur for each survey type. The final chapter focuses on the use of thermal and colour cameras for locating moose and explores a 22-km2 study site located at La Verendrye Provincial Park, Ontario. Collared moose travelling from Grand Portage Indian Reservation in Minnesota are visible in colour and thermal orthophotos. Moose thermal hotspots are computed from the thermal imagery, in a automated model. Hotspots were then examined manually. Two thermal hotspots over open water are misidentified as moose and 19 of 20 moose in the imagery were correctly identified by the automated search. Management implications of the study are that DS is a viable alternative to SRB surveys and that thermal aerial imagery is limited to animal counts without correction. Under the simulated conditions, DS performs comparably to SRB surveys and is possibly less expensive, or at least less variable in cost. Manual identification of moose by viewing colour imagery is still required to complement a thermal-imagery system, and sexing moose is not achievable from orthophotos alone.

Download or read book Resource Selection by Animals written by B.B. Manly and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: We have written this book as a guide to the design and analysis of field studies of resource selection, concentrating primarily on statistical aspects of the comparison of the use and availability of resources of different types. Our in tended audience is field ecologists in general and wildlife biologists in particular who are attempting to measure the extent to which real animal populations are selective in their choice of food and habitat. As such, we have made no attempt to address those aspects of theoretical ecology that are concerned with how animals might choose their resources if they acted in an optimal manner. The book is based on the concept of a resource selection function, where this is a function of characteristics measured on resource units such that its value for a unit is proportional to the probability of that unit being used. We argue that this concept leads to a unified theory for the analysis and interpretation of data on resource selection and can replace many ad hoc statistical methods that have been used in the past.

Download or read book Walking Dena ina written by Douglas Deur and published by . This book was released on 2021-02-04 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume describes Telaquana Trail, an ancient pathway ascending from the shores of Qizhjeh Vena, Lake Clark, through tundra and timbered valleys, into a high-elevation expanse of rolling tundra and smaller interior lakes nearly 50 miles north of Lake Clark. The pathway is an ancestral corridor used by Native peoples since the beginning of remembered time. The name "Telaquana Trail" first appears in the written record by no later than 1921, when Colonel A.J. Macnab, one of the first outsiders to visit the area for recreational big game hunting, mentioned taking a canoe to "go down the lake to look for the Telaquana Trail." Stephen Capps of the U.S. Geological Survey traveled and mapped the area in 1929. Producing the first detailed public map of the trail, Capps marks it as the "Native Route." As Dena'ina interviewees will attest, non-Native travel along the trail by this date was ample, but the corridor was still largely conceived of as Native space. Today, as the traces of significantly Anglo-American mining and trapping communities fade from the landscape, Dena'ina people still look to the trail corridor as a touchstone for their shared history and a cosmological axis of their own unique cultural geography. In the homes of Dena'ina people today, the landmarks of the Telaquana Trail are still remembered and the names of these places still spoken.
