Lake Mead Area, Nevada. Autumn 2007.
The leaves of cat claw acacia are gray-green, small and soft. They are drought deciduous in the summer heat and semi-deciduous in the winter cold, depending on the degree of chill.
Acacia's foliage, fruits and seeds provide browse for wildlife such as rabbits and birds. Various insects pollinate the flowers.
