A process which results in the assembly, arrangement of constituent parts, or disassembly of a presynaptic membrane, including any proteins associated with the membrane, but excluding other cellular components. A presynaptic membrane is a specialized area of membrane of the axon terminal that faces the plasma membrane of the neuron or muscle fiber with which the axon terminal establishes a synaptic junction.

Term information
Note that 'presynaptic membrane' in this term should not be mistaken with 'presynaptic active zone'. The latter encompasses more than the former, as it also includes the specialized cortical cytoskeletal matrix in the cell cortex of a presynaptic neuron.
