Systematic Reconnaissance Flight
Systematic Reconnaissance Flight (SRF) is a scientific method in wildlife Wildlife refers to domestication, undomesticated animal species (biology), species, but has come to include all organisms that grow or live wilderness, wild in an area without being species, introduced by humans. Wildlife was also synonymous ... survey for assessing the distribution and abundance of wild animals. It is widely used in Africa, Australia and North America for assessment of plains and woodland wildlife and other species. The method involves systematic or random flight lines ( transects) over the target area at a constant height above ground, with at least one observer recording wildlife in a calibrated strip on at least one side of the aircraft. The method has been often criticised for low accuracy and precision, but is considered to be the best option for relatively inexpensive coverage of large game areas.Hugo Jachmann, "Estimating Abundance of African Wildlife: An Aid to Adaptive Manage ...

Wildlife
Wildlife refers to undomesticated animal species, but has come to include all organisms that grow or live wild in an area without being introduced by humans. Wildlife was also synonymous to game: those birds and mammals that were hunted for sport. Wildlife can be found in all ecosystems. Deserts, plains, grasslands, woodlands, forests, and other areas, including the most developed urban areas, all have distinct forms of wildlife. While the term in popular culture usually refers to animals that are untouched by human factors, most scientists agree that much wildlife is affected by human activities. Some wildlife threaten human safety, health, property, and quality of life. However, many wild animals, even the dangerous ones, have value to human beings. This value might be economic, educational, or emotional in nature. Humans have historically tended to separate civilization from wildlife in a number of ways, including the legal, social, and moral senses. Some animals, how ...

Transect
A transect is a path along which one counts and records occurrences of the objects of study (e.g. plants). There are several types of transect. Some are more effective than others. It requires an observer to move along a fixed path and to count occurrences along the path and, at the same time (in some procedures), obtain the distance of the object from the path. This results in an estimate of the area covered and an estimate of the way in which detectability increases from probability 0 (far from the path) towards 1 (near the path). Using the raw count and this probability function, one can arrive at an estimate of the actual density of objects. The estimation of the abundance of populations (such as terrestrial mammal species) can be achieved using a number of different types of transect methods, such as strip transects, line transects, belt transects, point transects and curved line transect In mathematics, a curve (also called a curved line in older texts) is an object ...

African Wildlife Foundation
The African Wildlife Foundation (AWF) is the leading international conservation organization focused exclusively on Africa's wildlife and wild lands. AWF's programs and conservation strategies are designed to protect the wildlife and wild lands of Africa and ensure a more sustainable future for Africa's people. AWF protects Africa's wildlife, its wild lands, and its natural resources. Since its inception in 1961, the organization has protected endangered species and land, promoted conservation enterprises that benefit local African communities, and trained hundreds of African nationals in conservation. Early years The African Wildlife Leadership Foundation (AWLF) was founded in 1961 by Russell E. Train, a wealthy judge and hunter, and member of the Washington Safari Club. Other founding members from the Safari Club were Nick Arundel, a former United States Marine Corps combat officer and journalist; Kermit Roosevelt Jr. of the CIA; James S. Bugg, a businessman; and Maurice Stan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surveying
Surveying or land surveying is the technique, profession, art, and science of determining the terrestrial two-dimensional or three-dimensional positions of points and the distances and angles between them. A land surveying professional is called a land surveyor. These points are usually on the surface of the Earth, and they are often used to establish maps and boundaries for ownership, locations, such as the designed positions of structural components for construction or the surface location of subsurface features, or other purposes required by government or civil law, such as property sales. Surveyors work with elements of geodesy, geometry, trigonometry, regression analysis, physics, engineering, metrology, programming languages, and the law. They use equipment, such as total stations, robotic total stations, theodolites, GNSS receivers, retroreflectors, 3D scanners, LiDAR sensors, radios, inclinometer, handheld tablets, optical and digital levels, subsurface loc ...
