Bazinga game1/31/2024 ![]() “The use of small drones for wildlife surveys as a surrogate for manned aerial surveys is becoming increasingly attractive and has already been implemented with some success,” the researchers write. However, the researchers cautioned that IFP may not perform so well in rugged region as the flatlands. “Moreover, IFP accommodates aerial images with a low level of overlap or even without any overlap.” “The IFP method can be easily implemented in any GIS software and is not demanding in terms of image quality,” the researchers note. This method beat out using another means to georeference images, known as bundle block adjustments. However, how does one keep to a sampling strip while using drones? The researchers found that employing an image footprint projection (IFP) resulted in accurate counts. Animals seen outside the strip are not counted, allowing researchers to make estimates based on solid data. While conducting traditional aerial surveys, researchers count animals along a designated sampling strip. Recent test flights have also looked at the potential for drones to monitor marine ecosystems and uncover poachers. ![]() Consequently, some of them simply collapse between two surveys because no appropriate action have been taken.”ĭrones have rapidly become a popular tool for conservationists, and have been used to count orangutan nests, monitor recent deforestation, and map out palm oil plantations. ![]() This makes it impossible to quantify accurately the change in wildlife populations. “Consequently, in many African protected areas, the interval between two successive surveys can often be as great as 10 to 25 years. Manned aerial surveys “are quite expensive for most African wildlife managers, and it is therefore difficult to plan long-term and regular surveys,” the paper’s authors write. Researchers tested the accuracy of drone counts in Bazinga Game Ranch (NGR) in Burkina Faso. However a new study in ’s open access journal Tropical Conservation Science argues that using small drones may be more cost-effective, safer, and capable of reaching more remote areas. In open areas, like the African savannah, scientists often estimate wildlife populations through manned aerial surveys.
