Monitoring of animal populations is essential for conservation management. [] Key Method Chimpanzee nest data were collected through two approaches: we located nests on the ground and then tried to detect them in UAV photos and vice versa. Ground surveys were conducted using line transects, reconnaissance trails, and opportunistic sampling during which we detected 116 individual nests in 28 nest groups. In complementary UAV images we detected 48% of the individual nests (68% of nest groups) in open coastal…
Assessment of Chimpanzee Nest Detectability in Drone-Acquired Images
As with other species of great apes, chimpanzee numbers have declined over the past decades. Proper conservation of the remaining chimpanzees requires accurate and frequent data on their distribution
Successful aerial survey using thermal camera to detect wild orangutans in a fragmented landscape
Asia’s only great ape, the orangutan, builds nests for the night in the upper rainforest canopy. Due to the location in the upper canopy, aerial surveys of orangutans rely primarily on counting
A preliminary assessment of using conservation drones for Sumatran orang-utan (Pongo abelii) distribution and density
To conserve biodiversity, scientists monitor wildlife populations and their habitats. Current methods have constraints, such as the costs of ground or aerial surveys, limited resolution of freely
Seabird species vary in behavioural response to drone census
The UAV was unable to detect any impact of the UAV on breeding success of murres, except at a site where aerial predators were abundant and several birds lost their eggs to predators following UAV flights.
Thermal Infrared Imaging from Drones Offers a Major Advance for Spider Monkey Surveys
Accurate and precise population estimates form the basis of conservation action but are lacking for many arboreal species due to the high costs and difficulty in surveying these species. Recently,
Monitoring large and complex wildlife aggregations with drones
Recent advances in drone technology have rapidly led to their use for monitoring and managing wildlife populations but a broad and generalised framework for their application to complex wildlife
Integrating UAV Technology in an Ecological Monitoring System for Community Wildlife Management Areas in Tanzania
Unmanned aerial vehicles (UAV) have recently emerged as a new remote sensing aerial platform, and they are seemingly advancing real-time data generation. Nonetheless, considerable uncertainties
Precision wildlife monitoring using unmanned aerial vehicles
UAV technology is applied to wildlife monitoring in tropical and polar environments and it is demonstrated that UAV-derived counts of colony nesting birds are an order of magnitude more precise than traditional ground counts.


Aerial Surveys Give New Estimates for Orangutans in Sabah, Malaysia
It is shown that the number of nests detected during aerial surveys is directly related to the estimated true animal density and that a helicopter is an efficient tool to provide robust estimates of orangutan numbers.
Effective sociodemographic population assessment of elusive species in ecology and conservation management
This study highlights the potential of combining camera trapping and SECR methods in conducting detailed population assessments that go far beyond documenting species diversity patterns or estimating single species population size.
Distinguishing between the nests of sympatric chimpanzees and gorillas
This study introduces an innovative solution to the dilemma of discriminating between the nests of sympatric chimpanzees and gorillas, which increases the specificity and precision of resulting ape abundance estimates.
Non-Invasive Genetic Monitoring of Wild Central Chimpanzees
Genetic capture-recapture methods applied to apes can provide a considerable amount of novel information on chimpanzee population size and structure with minimal disturbance to the animals and represent a powerful complement to traditional field-based methods.
Nest building in orangutans
The chapter describes the basic nest-building technique used by orangutans, and draws attention to various special additions to this basic design, whose presence varies geographically.
Estimating population sizes for elusive animals: the forest elephants of Kakum National Park, Ghana
A genetic survey of the forest elephant population at Kakum National Park, Ghana was performed using multilocus genotyping of noninvasively collected samples, and the population size, sex ratio and genetic variability was very close to that obtained using dung counts.
Remote video-camera traps measure habitat use and competitive exclusion among sympatric chimpanzee, gorilla and elephant in Loango National Park, Gabon
The results emphasize the value of applying a multi-species, longer-term approach to studying variation in habitat use among sympatric species and highlight the impact competitors can exert on one another's distribution.
Monitoring mammal populations with line transect techniques in African forests
Summary 1.  Line transect survey techniques have been used to estimate population density for a variety of mammal species in tropical forests. In many cases indirect methods, surveying signs of
Dawn of Drone Ecology: Low-Cost Autonomous Aerial Vehicles for Conservation
Tropical deforestation continues to be a major driver of biodiversity loss and greenhouse gas emissions. Remote sensing technology is increasingly used to assess changes in forest cover, species
