What does VES mean in UNCLASSIFIED

A Visual Encounter Survey (VES) is a method for collecting data on wildlife populations by observing and counting animals from a distance. It involves driving along established routes and recording the species, number, and location of animals sighted.

VESs are used to estimate population sizes, monitor population trends, and assess the distribution and abundance of wildlife species. They are particularly valuable for species that are difficult to detect or capture, such as rare or elusive animals.

VESs typically involve trained observers driving along predetermined routes at a consistent speed. Observers use binoculars or spotting scopes to scan the landscape for animals, and they record the species, number, and location of each sighting. The data is often collected using electronic devices or GPS units.

VESs are a non-invasive and cost-effective method for collecting wildlife data. They can cover large areas, provide information on a wide range of species, and allow for repeated sampling over time. VESs are also useful for identifying areas of high wildlife use or habitat importance.

VESs can be affected by factors such as visibility, observer experience, and animal behavior. It can be challenging to accurately identify and count animals, especially at long distances or in dense vegetation. Additionally, VESs may not be suitable for all species or habitats.

VES data are analyzed to provide estimates of population size, density, and distribution. They can be used to track population trends over time, assess the impact of habitat changes or management interventions, and inform conservation decisions.
