fauna while maintaining subsistence harvest opportunities. Accomplishment of
these goals requires statistically-robust estimates of deer abundance. We
estimated deer abundances in non-forested, non-mountainous habitats of southern
Kodiak Island using double observer (mark-recapture) distance sampling applied
to traditional line-transect aerial counts... This survey provides the first statisticallyrobust
means of indexing annual trends in deer densities and abundances on
Kodiak Island
Monitoring ungulates in steep non-forest habitat: a comparison of faecal pellet and helicopter counts October 24, 2014 New Zealand, New Zealand Journal of Zoology
... There was a positive curvilinear (concave down) relationship between faecal pellet and helicopter counts. Compared with faecal pellet counts, helicopter counts were cheaper, could identify ungulate species and provided estimates of absolute density. Helicopter counts are a cost-effective method for monitoring ungulates in the steep non-forest habitats of New Zealand's Southern Alps...

2013 White-tailed Deer Surveys [PDF] Brian S. Haroldson, Farmland Wildlife Populations and Research Group. John H. Giudice, Wildlife Biometrics Unit
... The Minnesota Department of Natural Resources (MNDNR) uses simulation modeling within 125 permit areas (PA) to estimate and track changes in white-tailed deer... abundance and, subsequently, to develop harvest recommendations to keep deer populations within goal levels. In general, model inputs include estimates of initial population size, and spatial and temporal estimates of survival and reproduction for various age and sex cohorts. Because simulated population estimates are subject to drift as model input errors accumulate over time, it is imperative to periodically recalibrate the starting population within these models with independent deer population estimates (Grund and Woolf 2004)...
[PDF] Aerial-based Inventory Methods for Selected Ungulates: Mule Deer B Harris, F Iredale, B Jex, G Kuzyk, C Procter, A Reid. British Columbia - 2013
... Standard stratified random block surveys using helicopters are routinely used in many of the western United States, and have successfully been used to estimate Mule Deer population size in the Peace Region of British Columbia... Mule Deer show strong fidelity to small ranges in winter, so movements are limited and replicate counts of blocks have produced virtually identical results. The applicability of this method in other areas of the province has not been tested and thus stratified random block surveys for Mule Deer are not recommended. However, stratified random block surveys for Mule Deer may be possible once a sufficiently accurate/precise sightability model is developed.

Incorporating detection probability into northern Great Plains pronghorn population estimates CN Jacques, JA Jenks, TW Grovenburg, RW Klaver… Journal of Wildlife Management, 2013
... Detection probability of pronghorn was not constant but depended on both intrinsic and extrinsic factors. When pronghorn detection probability is a function of animal group size, animal activity, landscape complexity, and percent vegetation, traditional aerial survey techniques will result in biased pronghorn abundance estimates. Standardizing survey conditions, increasing resighting occasions, or accounting for variation in individual heterogeneity in mark-resight models will increase the accuracy and precision of pronghorn population estimates.

Using a Double-Count Aerial Survey to Estimate Moose Abundance in Maine August, 2013b LE Kantar, RE Cumberland - … : A Journal Devoted to the Biology and Management of Moose Abundance in Maine. 2013
... The Maine Department of Inland Fisheries and Wildlife most recently used the relationship between moose sightings by deer hunters and moose abundance to produce density indices within Wildlife Management Districts (WMD). Due to the marked decline of deer hunters in much of northern Maine that invalidates use of this technique, we tested a double-count aerial survey method to estimate moose abundance in 9 northern WMDs. ...The density estimates tracked closely with trends in moose sighting rate by moose hunters, harvest level, and hunter success rate in the survey area, and were consistent with jurisdictions in eastern Canada that also have low levels of predation and a preponderance of younger-aged forests. The double-count aerial survey is considered the preferred method to estimate population density, whereas hunter sighting indices would be most useful to track temporal population changes within a WMD.
Using DNA to Test the Utility of Pellet‐Group Counts as an Index of Deer Counts
TJ Brinkman, DK Person, W Smith, FS Chapin… - Wildlife Society Bulletin, 2013
... Despite widespread use of fecal pellet-group counts as an index of ungulate density, techniques used to convert pellet-group numbers to ungulate numbers rarely are based on counts of known individuals, seldom evaluated across spatial and temporal scales, and precision is infrequently quantified... Assuming that our DNA-based results were a more accurate and precise metric of true deer count, we do not support the use of pellet-group count to index deer count in southeast Alaska unless confounding factors are accounted for at fine spatial (e.g., habitat patch) scales...
Reliability and precision of pellet-group counts for estimating landscape-level deer density 2013 Human-Wildlife Interactions. 7(1): 60-68.
...This study provides hitherto unavailable methodology for reliably and precisely estimating deer density within forested landscapes, enabling quantitative rather than qualitative deer management... Precision on the small landscape was high; 95% confidence intervals for individual counters were <7.5% of mean estimates of density, and coefficients of variability were <10%. Precision on the larger landscapes was acceptable: 95% confidence intervals were 18.4 to 30.4% of mean estimates and coefficients of variability were <25%. The pellet-group technique produces reliable and precise estimates of deer density, is inexpensive, requires little training to implement, and is best suited to northern hardwood forests where snow and cold result in minimal deterioration of pellet groups. Unless corrected for hunter harvest and overwinter mortality, pellet-group counts represent average overwinter density and overestimate spring density...
Road bias for deer density estimates at 2 national parks in Maryland September 22, 2011 Wildlife Society Bulletin, William J. McShea, Chad M. Stewart, Laura Kearns, Scott Bates
Estimating the population density of deer is an essential task for public agencies that plan a herd reduction... Many of these surveys are conducted along public roads due to limited resources and accessibility, which may violate a critical assumption of distance sampling and potentially introduce sampling bias. We used infrared cameras to confirm deer activity with respect to survey roads ... Although density estimation using DISTANCE can account for most sources of error introduced by use of public roads, our data indicate bias is likely to occur in landscapes with high road densities and long sight distances...

Aerial Censusing of White-Tailed Deer and Comparison to Sex-Age-Kill Population Estimates in Northern Indiana 1997. SJ Burgdorf, HP Weeks Jr, Proceedings of the Indiana Academy of Science, 2013
... : Accurate estimates of population size and composition are important for effective deer management. White-tailed deer {Odocoileus virgini- anus) population estimates were obtained in two northern Indiana Counties, Marshall and Steuben, by winter aerial censusing in 1990 and 1991. To optimize helicopter flight time and decrease the variance among sample areas,stratified random sampling with optimal allocation was used to census 25% of each County. Ground truthing a subsample of woodlots provided a check on the accuracy of the aerial counts. Mean posthunt deer density calculated from aerial counts was 0.09 deer/ha in Steuben County in 1990 and 1991. In 1991, mean deer density in Marshall County was 0.04/ha. Compared to combined ground counts, the aerial counts were 93% accurate. Stratified counts from a helicopter were relatively accurate for northern Indiana when adequate snow cover was present. Population estimates from aerial counts approxi- mated the sex-age-kill model estimates.
The value of a random sampling design for annual monitoring of national populations of larger British terrestrial mammals LJ Wright, SE Newson, DG Noble - European Journal of Wildlife Research, 2013
Making use of an extensive network of volunteer birdwatchers, this study illustrates how a large-scale monitoring scheme originally designed for common breeding birds can be adapted to also provide robust monitoring data for medium- to large-sized, easily detectable terrestrial mammals. Compared with bird monitoring, the monitoring of common and widespread terrestrial mammals is rarely carried out using a well-designed sampling design and is largely restricted to sites selected by the observer or biased towards particular habitats of interest, making it difficult to know whether trends are representative of the populations of interest.... Here, we present population trends at national and regional scales for nine species of common mammal over the first 18 years of BBS mammal monitoring and examine these in relation to our current knowledge on these species...

... we present a statistical framework for analyzing movement data that is based on the concept of a potential surface. The potential surface is motivated by the assumption that animals are moving on a space-time surface with regions or points of attraction or of repulsion. We demonstrate the use of the technique by analyzing movement data from a long-term controlled experiment to evaluate the responses of free ranging Rocky Mountain elk (Cervus elaphus) to anthropogenic disturbances that vary in time and space. Our results demonstrated a strong avoidance of elk to all-terrain vehicles detected up to one km from the disturbance...
