  • ESTIMATION OF MOOSE PARTURITION DATES IN COLORADO: INCORPORATING IMPERFECT
           DETECTIONS

    • Authors: Eric J. Bergman, Forest P. Hayes, Kevin Aagaard
      Abstract: Researchers and managers use productivity surveys to evaluate moose populations for harvest and population management purposes, yet such surveys are prone to bias. We incorporated detection probability estimates (p) into spring and summer ground surveys to reduce the influence of observer bias on the estimation of moose parturition dates in Colorado. In our study, the cumulative parturition probability for moose was 0.50 by May 19, and the probability of parturition exceeded 0.9 by May 27. Timing of moose calf parturition in Colorado appears synchronous with parturition in more northern latitudes. Our results can be used to plan ground surveys in a manner that will reduce bias stemming from unobservable and yet-born calves.

  • ABUNDANCE OF WINTER TICKS (DERMACENTOR ALBIPICTUS) IN TWO REGENERATING
           FOREST HABITATS IN NEW HAMPSHIRE, USA

    • Authors: Brent I. Powers, Peter J. Pekins
      Pages: 1 - 13
      Abstract: Recent decline in New Hampshire’s moose (Alces alces) population is attributed to sustained parasitism by winter ticks (Dermacentor albipictus) causing high calf mortality and reduced productivity. Location of larval winter ticks that infest moose is dictated by where adult female ticks drop from moose in April when moose preferentially forage in early regenerating forest in the northeastern United States. The primary objectives of this study were to: 1) measure and compare larval abundance in 2 types of regenerating forest (clear-cuts and partial harvest cuts), 2) measure and compare larval abundance on 2 transect types (random and high-use) within clear-cuts and partial harvests, and 3) identify the date and environmental characteristics associated with termination of larval questing. Larvae were collected on 50.5% of 589 transects; 57.5% of transects in clear-cuts and 44.3% in partial cuts. The average abundance ranged from 0.11–0.36 ticks/m2 with abundance highest (P < 0.05) in partial cuts and on high-use transects in both cut types over a 9-week period; abundance was ~2 × higher during the principal 6-week questing period prior to the first snowfall. Abundance (collection rate) was stable until the onset of < 0°C and initial snow cover (~15 cm) in late October, after which collection rose temporarily on high-use transects in partial harvests during a brief warm-up. The higher abundance of winter ticks on high-use transects indicates that random sampling underestimates tick abundance and relative risk of infestation of moose. Calculating an annual index of infestation of winter ticks on moose is theoretically possible by integrating 3 factors: the infestation of harvested moose in October, the length of the questing period, and assuming a stable collection rate during the questing period.

  • METRICS OF HARVEST FOR UNGULATE POPULATIONS: MISCONCEPTIONS, LURKING
           VARIABLES, AND PRUDENT MANAGEMENT

    • Authors: R. Terry Bowyer, Kelley M. Stewart, Vernon C. Bleich, Jericho C. Whiting, Kevin L. Monteith, Marcus E. Blum, Tayler N. LaSharr
      Pages: 15 - 38
      Abstract: Biologists often must use incomplete information to make recommendations concerning harvest of large mammals. Consequently, those recommendations must draw on a firm understanding of the ecology of the species in question, along with selection of the most applicable population characteristics on which to base harvest—both essential components for prudent management. Density-dependent processes, which are ubiquitous among populations of large mammals, may be counterintuitive because of unexpected patterns in recruitment coincident with changes in population size. Misconceptions concerning population dynamics of ungulates also can occur when demographics are based solely on correlations with environmental factors. Further, the concept of a harvestable surplus can be misleading for managing ungulate populations, because of the parabolic relationship between population size and number of recruits—harvest determines the surplus rather than vice versa. Understanding consequences of mortality, especially relative components of compensatory or additive mortality, also is necessary. Knowledge of the proximity of an ungulate population to ecological carrying capacity (K) is required to fully assess whether most mortality is compensatory or additive. We describe selected life-history traits and population characteristics of ungulates useful in parametrizing where populations are in relation to K, thereby allowing for a reasonable harvest despite some uncertainty in population size. We advocate an adaptive-management approach while monitoring those life-history traits to evaluate the suitability of a particular harvest strategy.

  • REVISITING THE RECRUITMENT-MORTALITY EQUATION TO ASSESS MOOSE GROWTH RATES

    • Authors: Ian W. Hatter
      Pages: 39 - 47
      Abstract: Hatter and Bergerud (1991) developed a recruitment-mortality (R-M) equation to estimate the annual finite rate of change (λ) in a moose (Alces alces) population from a single estimate of calf recruitment and adult mortality. I present and assess an alternative formulation of the R-M equation and compare it with the original. A modification to the R-M equations is provided to accommodate early to mid-winter composition surveys where recruitment is measured when calves are less than 1 year-of-age. An example with the modified R-M equation illustrates estimation of λ for the female component of two moose populations under recent study in British Columbia, Canada. Due to potential biases with estimating recruitment and mortality rates, the calculation of λ with the R-M equation should be verified with periodic density surveys whenever possible. The R-M equation is most useful for estimating λ when moose density surveys are not feasible or an estimate of the adult survival rate is available.

  • TRACKING MOOSE- AND DEER-VEHICLE COLLISIONS USING GPS AND LANDMARK
           INVENTORY SYSTEMS IN BRITISH COLUMBIA

    • Authors: Caleb Sample, Roy V. Rea, Gayle Hesse
      Pages: 49 - 61
      Abstract: Vehicle collisions with moose (Alces alces) and deer (Odocoileus spp.) pose a serious threat to all motorists travelling highways traversing habitats of these two ungulates. In British Columbia, mitigation measures to reduce such collisions are based on spatially-accurate records of collisions involving moose and deer that are collected by the province’s highway maintenance contractors. To date, the British Columbia Ministry of Transportation and Infrastructure (BC MOTI) uses the paper-based Wildlife Accident Reporting System (WARS) established in 1978 to maintain carcass records. We compared carcass location data collected in 2010 to 2014 by BC MOTI using WARS to that collected by Northern Health Connections bus drivers using a newly developed GPS-based system (Otto® Wildlife device). In total, 6,929 carcasses (1,231 moose, 5,698 deer) were recorded using WARS and 474 (167 moose, 410 deer) using the Otto® Wildlife device. We compared data collected along 2,800 km on the same highways in the same seasons of the same years. We found more carcass locations were identified with the WARS method, but that in certain geographic regions, the Otto® Wildlife system identified several unique locations. We contend that more complete and finer-scale carcass location data is possible using a GPS-based system such as Otto® Wildlife, than currently collected solely with the paper-based WARS method.

      Abstract: Moose (Alces alces) may be among one of the most susceptible big game species to climate change. Development of long-term circumpolar databases of this species’ densities and distributions, combined with biological, ecological, and management-related metrics, can help guide research and future international management strategies. We emulated methodology previously used to summarize North American moose population and harvest densities for Eurasian countries with free-ranging moose populations. From these data, we created a GIS layer that summarized the circumpolar distribution and density of moose. The following summary analysis of these data indicates that moose have both expanded and contracted along their southern range boundary in recent decades – with losses along the southern range in eastern Asia, particularly China, Mongolia, and Kazakhstan. In contrast, we documented distributional gains along the western and southwestern range in Europe (Poland, Germany, Czech Republic, Slovakia). In total, 21 countries have free-ranging moose populations; 8 with sustainable populations and hunting seasons, 5 with sustainable populations but no hunting season, and 8 with vagrant individuals occasionally sighted. A region of high-density moose populations spans from the Scandinavian and Baltic countries into the Russian oblasts of Perm and Sverdlovsk. Distributions ca. 2010 indicated that moose occupied an area of about 16,712,600 km2 in Eurasia. Primary range (management units with ≥0.11 moose per km2) composed only 18% of the occupied range while supporting more than 66% of the estimated 1.2 million moose in Eurasia. Additionally, 47% (149,860) of the moose harvested were taken on 10% (1,722,660 km2) of the range. The 2010 circumpolar moose population was estimated to be more than 2.2 million and occupied a range of 26,205,000 km2. Time-series analyses can offer a simple and cost-effective approach to monitor the status of moose populations across large geographical regions and might be particularly insightful given the current and predicted future influences of climate change on moose. Other analyses might address population dynamics, habitat, environmental constraints, and harvest management, among other issues. We encourage jurisdictions to cooperate strategically in implementing and coordinating GIS analyses to monitor, assess, and manage moose populations around the world. We believe these maps can serve as a useful tool for educating the public and policy makers about the importance of habitat and land use practices with respect to maintaining sustainable populations of moose and other species that are dependent upon boreal, temperate broadleaf, and mixed forests.
