AW Parsons, T Forrester, WJ McShea… - Journal of Mammalogy, 2017
... Density estimation using camera-trap data is a commonly desired outcome, but most approaches only work for species that can be individually recognized, and researchers studying most mammals are typically constrained to measures of site occupancy or detection rate... Using occupancy or detection rate as proxies for density may be particularly problematic when comparing between areas where animals might to move or behave differently, such as urban–wild interfaces. In such cases, alternate methods of density approximation are recommended...

Noninvasive genetic spatial capture‐recapture for estimating deer population abundance  JL Brazeal, T Weist, BN Sacks - The Journal of Wildlife Management, 2017
... For deer (Odocoileus spp.), the use of closed-population, capture-recapture (CR) methods, in conjunction with noninvasive DNA sampling, has become increasingly practical, but, up to now, these methods have been used in a non-spatial modeling framework, which has limited their utility for population-level inferences.  ... In comparison, non-spatial CR analysis produced density estimates on average 60% higher, likely reflecting bias resulting from use of the commonly employed mean maximum recapture distance (MMRD) to estimate effective sampling area.

Saving time and money by using diurnal vehicle counts to monitor roe deer abundanc M Pellerin, A Bessière, D Maillard, G Capron… - Wildlife Biology, 2017
... Despite being a widespread and important game species in Europe, scientifically reliable, easy applicable and cost effective methods for monitoring abundance of roe deer Capreolus capreolus populations do not yet exist... The positive correlation of AI-p and AI-v with CMR density estimates as well as the reduced costs of conducting surveys by car instead on foot (-47%) suggest that diurnal vehicle counts of roe deer can provide a suitable abundance index to monitor temporal trends in roe deer populations at operational management scales...

The Truth About Spotlight Deer Surveys January 24, 2017 South Carolina, deeranddeerhunting.com
...  in South Carolina called Brosnan Forest. ... Researchers identified 4,508 deer during 79 Bronson Forest surveys. Thermal imagers detected 85 percent (3,861 deer) of the total deer seen, and spotlights detected only 48 percent (2,174 deer) of the total... This study demonstrated that the likelihood of detecting an individual whitetail during spotlight surveys is very low, averaging about 41 percent of the time...

MC Chitwood, MA Lashley, JC Kilgo, MJ Cherry… - Wildlife Biology, 2016
... At Savannah River Site, South Carolina, we used six years of camera-based recruitment estimates (i.e. fawn:doe ratio) to predict concurrently collected annual radiotag-based survival estimates. The coefficient of determination (R2) was 0.445, indicating some support for the viability of cameras to reflect recruitment... because so few researchers concurrently estimate survival and camera-based recruitment, examining this relationship at larger spatial scales while controlling for numerous confounding variables remains difficult...

AnimalFinder: A semi-automated system for animal detection in time-lapse camera trap images JLP Tack, BS West, CP McGowan, SS Ditchkoff… - Ecological Informatics, 2016
... Although the use of camera traps in wildlife management is well established, technologies to automate image processing have been much slower in development, despite their potential to drastically reduce personnel time and cost required to review photos. We developed AnimalFinder in MATLAB® to identify animal presence in time-lapse camera trap images by comparing individual photos to all images contained within the subset of images ... Our results show that the program significantly reduced data processing time and may increase efficiency of camera trapping surveys...

... The reliability of spotlight-based indices to monitoring deer population changes has been widely debated, possibly owing to inconsistent performances of the method in different landscapes. For mountain-dwelling deer populations living in similar habitats, our results suggest that spring spotlight surveys represent valuable tools in support of wildlife managers for long-term, large-scale monitoring programs; furthermore, they can provide appropriate indices to estimating population growth rates and thus modelling deer population dynamics...

S Pfeffer - 2016
... For moose, camera traps yielded a population estimate similar to dung counts. However, estimated densities from the dung count approach were much lower for all other three ungulate species than densities from the camera trapping. Even though the use of camera traps is more time consuming and costly, this method is evaluated as a trustworthy estimator of population sizes. In addition, further information about habitat associations, activity patterns, behaviour, or community structure can be successfully accomplished...

TR Hofmeester, JM Rowcliffe, PA Jansen - Remote Sensing in Ecology and …, 2016
... Camera traps can be used to estimate the abundance of terrestrial mammals, including elusive species, provided that the sensitivity of the sensor, estimated as the effective detection distance (EDD), is quantified... EDD estimates derived from simulated passages using binned detection distances approximated those obtained from continuous detection distance measurements if at least five intervals were used over the maximum detection distance...

Employing Ultrahigh-Frequency RFID Technology on Deer Farm Managment  L Hsiao-Mei, W Chih-Hwa, H Yan-Der, H Kuo-Hsiang - Indian Journal of Animal …, 2015
... This project uses ultrahigh-frequency (UHF) ear tags and readers with a readable range of 3 to 5 m. Forty stags were tagged with radio-frequency identification (RFID) ear tags and allocated into 20 pens. When deer with RFID ear tags walked through the aisle, handheld RFID readers, used as personal digital assistants (PDAs), and stationary RFID readers in frequency range received signals from the tags, and individual deer tag data were transmitted immediately and completely through wireless PDAs to a computer. The inputted data were sent to the deer-farm management system to be collated and organized. Farmers obtained individual deer data without approaching the deer, which decreased the risk of the deer attacking. Employing UHF-RFID technology integrated with software contributes to enhancing the efficiency of deer identification and farm management.,,

... In this study, we compare the results of roe deer sampling based on distance detection performed by two techniques: surveys on foot in the evening and nocturnal surveys by car... when it is necessary to estimate absolute densities of roe deer populations, nocturnal distance sampling by car seems to be the most appropriate method due to its low cost, yet the influence of the vehicle on the distribution of roe deer and, therefore, on the estimated density, must be taken into account when carrying out such studies.

... I estimated deer density and population size on Blakely Island, WA, using the fecal standing crop (FSC) method described by Martin et al. (2011). I compared the FSC method with a well established and broadly applicable estimation method, distance sampling...  As the FSC density estimation was much greater than that of distance sampling, and because it did not compare to other high-density island populations of deer, I concluded that this newer technique may not be comparable to well established methods...

Animals Spy a New Enemy: Drones October 20, 2015 New York Times

They rarely made an attempt to evade the drones ...

Estimating sex‐specific abundance in fawning areas of a high‐density Columbian black‐tailed deer population using fecal DNA ZT Lounsberry, TD Forrester, MT Olegario, JL Brazeal… - The Journal of Wildlife …, 2014, California
... The recent development of fecal-genetic capture-mark-recapture (CMR) methods has increased the feasibility of estimating abundance of forest-dwelling ungulates that are difficult to survey using visual methods. Unless genetic markers differentiating sex are incorporated into such studies, however, genetic CMR approaches risk missing sex-specific differences in population trends.... Incorporating sex and individual markers into a single assay provided a cost-effective means of applying CMR estimation based on fecal DNA to a high-density ungulate population in a forested ecosystem and emphasized the importance of explicitly modeling sex in abundance estimation.

   Management goals for Sitka black-tailed deer (Odocoileus hemionus sitkensis) at
Kodiak National Wildlife Refuge are to minimize deer impacts to native flora and
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

... 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.

Aerial vertical‐looking infrared imagery to evaluate bias of distance sampling techniques for white‐tailed deer JT Beaver, CA Harper, RE Kissell, LI Muller… - Wildlife Society Bulletin, 2014
... Despite its higher cost (US$10,000) over spotlight surveys, we recommend aerial imaging instead of road-based ground surveys for monitoring populations of deer and discourage the continued use of non-random road-based surveys as a method for estimating white-tailed deer populations.

Comparison of occupancy modeling and radiotelemetry to estimate ungulate population dynamicJF Duquette, JL Belant, NJ Svoboda, DE Beyer Jr… - Population Ecology, 2014
... Radiotelemetry and unmarked occupancy modeling have been used to estimate animal population growth, but have not been compared for ungulates. ... Radiotelemetry provided more precise population growth estimates, while allowing collection of vital rates and location data. However, the Royle–Nichols occupancy model may be preferred to radiotelemetry because it reflected yearly variation in population growth with reduced labor and no invasive marking...

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.

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...

...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. 

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...
