The short answer is yes...... but with provision.

Lion are highly territorial but the size of their range is specific area dependent. Ie depending on where ( location in terms of country or eco zone the size of the territories will vary)

Based on this then Scientists who study lion specifically are able to locate and monitor movement with astounding accuracy, especially in high concentration areas. Much more so than PH's who rely more on chance encounters than anything else.

As a student at varsity I hung with guys who studied Wildlife management at Pretoria Univeristy on post graduate basis and based on the particular course director at that time all had something to do with the study and movement of the large cats of Africa.

We have lion on our ranch and based on their perculiar territorial behaviour our game guides are able to locate them on any given day. Sometimes it may take a day or so but on most occasions they seem to know where they hang.

Study areas such as the Kruger, Botswana and parts of Tanzania are so well studied that the range areas are actually mapped and individuals within prides are known by name and number. I have had friends who have lived in the bush for periods of up to 3 years tracking specific prides and recording their daily acitivities an a log. Even the Illusive Leopard is studied in this manner.
