Mountain gazelle counts in Ramat Hanadiv Nature Park 2004 - 2020.csv

Gazelle surveys were conducted along a 12.2 km route, corresponding to a sampling intensity of 2.4 km per 1.0 km2. Driving speed was about 6 km/h along pre-established, unpaved roads traversing most parts of the park. Surveys were repeated four times a month, starting twice at sunrise (dawn surveys), and twice two hours before sunset (dusk surveys). During surveys, the observer scanned along both sides of the route, occasionally using binoculars to search for gazelles at elevated points with a good overview. For each gazelle encounter the sex/age class was identified as either male or female/subadult, because separating adult females from subadult gazelles was difficult, due to similar body size and the absence of horns in many adult females, which makes them look like subadults. Additionally, females and subadults usually move together. The approximate location of each observation was recorded using GPS.
