LOWER CALIFORNIA 
Antelope in Lower California are distributed mainly on the plains east of 
the central mountain range from the California border south to the middle of 
the peninsula. They are also on the desert of Vizcaino, where they live west 
of the main mountain range, reaching the borders of the Pacific on the shores 
of Vizcaino Bay on the north and Ballenas Bay on the south. It is estimated 
that not less than 500 antelope survive on the peninsula. Formerly antelope 
in Lower California ranged south beyond Magdalena Bay, but for many years 
they have been extinct over a large part of their former territory. During the 
past 15 years antelope have been continuously hunted in Lower California, and 
it is rather surprising that they have continued to survive. It is hoped that 
the operation of the present close season on them may result in their numbers 
again increasing. Natural conditions are such that Lower California will 
never be densely populated or occupied by farming communities of any im- 
portance. Water is scarce in the interior, and great plains covered with 
desert vegetation afford an ideal home for antelope. With reasonable protec- 
tion they might survive there in large numbers far into the future (fig. 21).
