Title Fast, flexible alternatives to regular grid designs for spatial capture–recapture. Type Research Article
Year 2020 Publication (down) Methods in Ecology and Evolution Abbreviated Journal
Volume Issue Pages 1-13
Keywords camera trap, population ecology,sampling, spatial capture-recapture, surveys
Abstract Spatial capture–recapture (SCR) methods use the location of

detectors (camera traps, hair snares and live-capture traps) and the

locations at which animals were detected (their spatial capture

histories) to estimate animal density. Despite the often large expense

and effort involved in placing detectors in a landscape, there has been

relatively little work on how detectors should be located. A natural

criterion is to place traps so as to maximize the precision of density

estimators, but the lack of a closed-form expression for precision has

made optimizing this criterion computationally demanding. 2. Recent

results by Efford and Boulanger (2019) show that precision can be well

approximated by a function of the expected number of detected

individuals and expected number of recapture events, both of which can

be evaluated at low computational cost. We use these results to develop

a method for obtaining survey designs that optimize this approximate

precision for SCR studies using count or binary proximity detectors, or

multi-catch traps. 3. We show how the basic design protocol can be

extended to incorporate spatially varying distributions of activity

centres and animal detectability. We illustrate our approach by

simulating from a camera trap study of snow leopards in Mongolia and

comparing estimates from our designs to those generated by regular or

optimized grid designs. Optimizing detector placement increased the

number of detected individuals and recaptures, but this did not always

lead to more precise density estimators due to less precise estimation

of the effective sampling area. In most cases, the precision of density

estimators was comparable to that obtained with grid designs, with

improvement in some scenarios where approximate CV(¬D) < 20% and density

varied spatially. 4. Designs generated using our approach are

transparent and statistically grounded. They can be produced for survey

regions of any shape, adapt to known information about animal density

and detectability, and are potentially easier and less costly to

implement. We recommend their use as good, flexible candidate designs

for SCR surveys when reasonable knowledge of model parameters exists. We

provide software for researchers to construct their own designs, in the

form of updates to design functions in the r package oSCR.

Title Assessing Estimators of Snow Leopard Abundance Type Miscellaneous
Year 2008 Publication (down) Journal of Widlife Management Abbreviated Journal
Volume 72 Issue 8 Pages 1826-1833
Keywords abundance; camera,capture-recapture,density,index,predator:prey ratios,techniques,Tien Shan,Uncia; leopard; SaryChat; sign surveys; Slims; snow; snow-leopard; snow leopard; Tomur
Abstract The secretive nature of snow leopards (Uncia uncia) makes them difficult to monitor, yet conservation efforts require accurate and precise methods to estimate abundance. We assessed accuracy of Snow Leopard Information Management System (SLIMS) sign surveys by comparing them with 4 methods for estimating snow leopard abundance: predator:prey biomass ratios, capture-recapture density estimation, photo-capture rate, and individual identification through genetic analysis. We recorded snow leopard sign during standardized surveys in the SaryChat Zapovednik, the Jangart hunting reserve, and the Tomur Strictly Protected Area, in the Tien Shan Mountains of Kyrgyzstan and China. During June-December 2005, adjusted sign averaged 46.3 (SaryChat), 94.6 (Jangart), and 150.8 (Tomur) occurrences/km. We used

counts of ibex (Capra ibex) and argali (Ovis ammon) to estimate available prey biomass and subsequent potential snow leopard densities of 8.7 (SaryChat), 1.0 (Jangart), and 1.1 (Tomur) snow leopards/100 km2. Photo capture-recapture density estimates were 0.15 (n = 1 identified individual/1 photo), 0.87 (n = 4/13), and 0.74 (n = 5/6) individuals/100 km2 in SaryChat, Jangart, and Tomur, respectively. Photo-capture rates

(photos/100 trap-nights) were 0.09 (SaryChat), 0.93 (Jangart), and 2.37 (Tomur). Genetic analysis of snow leopard fecal samples provided minimum population sizes of 3 (SaryChat), 5 (Jangart), and 9 (Tomur) snow leopards. These results suggest SLIMS sign surveys may be affected by observer bias and environmental variance. However, when such bias and variation are accounted for, sign surveys indicate relative abundances similar to photo rates and genetic individual identification results. Density or abundance estimates based on capture-recapture or ungulate biomass did not agree with other indices of abundance. Confidence in estimated densities, or even detection of significant changes in abundance of snow leopard, will require more effort and better documentation.

Abstract Solitary felids like tigers and snow leopards are notoriously difficult to enumerate, and indirect techniques like pugmark surveys often produce ambiguous information that is difficult to interpret because many factors influence marking behavior and frequency (Ahlborn & Jackson 1988). Considering the snow leopard's rugged habitat, it is not surprising then that information on its current status and occupied range is very limited. We adapted the camera-trapping techniques pioneered by Ullas Karanth and his associates for counting Bengal tigers to the census taking of snow leopards in the Rumbak watershed of the India's Hemis High Altitude National Park (HNP), located in Ladakh near Leh (76ø 50' to 77ø 45' East; 33ø 15' to 34ø 20'North).

Title Leopards in African Rainforests: Survey and Monitoring Techniques Type Miscellaneous
Year 2003 Publication (down) Abbreviated Journal
Volume Issue Pages
Keywords forest leopards; african rainforests; survey; monitoring techniques; lope reserve; gabon; central africa; congo; zaire; field testing; populations; wild meat; relative abundance; density; live-trapping; presence and absense surveys; ad-hoc survey; bushmeat; systematic survey; monitoring; individual identification; tracks; Discriminant Function Analysis; genotyping; scat; Hair; Dna; remote photography; camera trapping; capture rates; Trailmaster; Camtrakker; bait; duikers; pigs; elephant; bongo; okapi; human hunters; 5300
Abstract Monitoring Techniques Forest leopards have never been systematically surveyed in African forests, in spite of their potentially vital ecological role as the sole large mammalian predators in these systems. Because leopards are rarely seen in this habitat, and are difficult to survey using the most common techniques for assessing relative abundances of forest mammals, baseline knowledge of leopard ecology and responses to human disturbance in African forests remain largely unknown. This technical handbook sums up the experience gained during a two-year study of leopards by Philipp Henschel in the Lop‚ Reserve in Gabon, Central Africa, in 2001/2002, supplemented by additional experience from carnivore studies conducted by Justina Ray in southwestern Central African Republic and eastern Congo (Zaire) . The main focus of this effort has been to develop a protocol that can be used by fieldworkers across west and central Africa to estimate leopard densities in various forest types. In developing this manual, Henschel tested several indirect methods to assess leopard numbers in both logged and unlogged forests, with the main effort devoted to testing remote photography survey methods developed for tigers by Karanth (e.g., Karanth 1995, Karanth & Nichols 1998; 2000; 2002), and modifying them for the specific conditions characterizing African forest environments. This handbook summarizes the results of the field testing, and provides recommendations for techniques to assess leopard presence/absence, relative abundance, and densities in African forest sites. We briefly review the suitability of various methods for different study objectives and go into particular detail on remote photography survey methodology, adapting previously developed methods and sampling considerations specifically to the African forest environment. Finally, we briefly discuss how camera trapping may be used as a tool to survey other forest mammals. Developing a survey protocol for African leopards is a necessary first step towards a regional assessment and priority setting exercise targeted at forest leopards, similar to those carried out on large carnivores in Asian and South American forests.

Abstract In accordance with order of the Ministry of Nature and Tourism,

zoologists of our association have made surveys in three ways such as

reasons why snow leopards attack domestic animals, “Snow leopard” trial

operation to count them and illegal hunting in territories of Khovd,

Gobi-Altai, Bayankhongor, Uvurkhangai and Umnugobi provinces from

September 2009 to January 2010. As result of these surveys it has made

the following conclusions in the followings: Reason to hunt them illegally: the principal reason is that

administrative units have been increased and territories of

administrative units have been diminished. There have been four

provinces in 1924 to 1926, 18 since 1965, 21 since 1990. Such situation

limits movements of herdsmen completely and pastures digressed much than

ever before. As result of such situation, 70% of pastures become desert.

Such digression caused not only heads of animals and also number of

species. Guarantee is that birds such as owls, cuckoo, willow grouse in

banks of Uyert river, Burkhanbuudai mountain, located in Biger soum,

Gobi-Altai province, which are not hunted by hunters, are disappearing

in the recent two decades. For that reason we consider it is urgently

necessary for the government to convert administrative unit structures

into four provinces. This would influence herdsmen moving across

hundreds km and pastures could depart from digression.

Second reason: cooperative movement won. The issues related to management and strengthening of national

cooperatives, considered by Central Committee of Mongolian People's

Revolutionary Party in the meeting in March 1953 was the start of

cooperatives' movement. Consideration by Yu. Tsedenbal, chairman of

Ministers Council, chairman of the MPRP, on report “Result of to unify

popular units and some important issues to maintain entity management of

agricultural cooperatives” in the fourth meeting by the Central

Committee of Mongolian People's Revolutionary Party /MPRP/ on December

16-17, 1959, proclaimed complete victory of cooperative. At the end of

1959, it could unify 767 small cooperative into 389 ones, unify 99.3 %

of herdsmen and socialize 73.3 % of animals. The remaining of animals

amount 6 million 163 thousands animals, and equals to 26.7% of total

animals. This concerned number of animals related to the article

mentioned that every family should have not more that 50 animals in

Khangai zone and not more 75 animals in Gobi desert. It shows that such

number could not satisfy needs of family if such number is divided into

five main animals in separating with reproduction animals and adult

animals. So herdsmen started hunt hoofed animals secretly and illegally

in order to satisfy their meat needs. Those animals included main food

of snow leopard such as ibex, wild sheep, and marmot. Third reason is that the state used to hunt ibex, which are main

nutrition of snow leopards, every year. The administrative unit of the

soum pursued policy to hunt ibex in order to provide meat needs of

secondary schools and hospitals. That's why this affected decrease of

ibex population. Preciously from 1986 to 1990 the permissions to hunt

one thousands of wild sheep and two thousands of ibexes were hunt for

domestic alimentary use every year. Not less than 10 local hunters of every soum used to take part in big

game of ibexes. Also they hunted many ibexes, chose 3-10 best ibexes and

hid them in the mountains for their consummation during hunting.

Fourth reason: hunting of wolves. Until 1990 the state used to give

prizes to hunter, who killed a wolf in any seasons of the year. Firstly

it offered a sheep for the wolf hunter and later it gave 25 tugrugs /15

USD/. Every year, wolf hunting was organized several times especially

picking wolf-cubs influenced spread and population of wolves. So snow

leopard came to the places where wolves survived before and attack

domestic animals. Such situation continued until 1990. Now population of

ibexes has decreased than before 1990 since the state stopped hunting

wolves, population of wolves increased in mountainous zones. We didn't

consider it had been right since it was natural event. However

population of ibexes decreased. Fifth reason: Global warming. In recent five years it has had a drought

and natural disaster from excessive snow in the places where it has

never had such natural disasters before. But Mongolia has 40 million

heads of domestic animals it has never increased like such quantity in

its history before. We consider it is not incorrect that decrease of

domestic animals could give opportunities to raise population of wild

animals. Our next survey is to make attempt to fix heads of snow leopards

correctly with low costs.
