The quality or capacity of being able to be colonised; the degree to which a territory, organism, or surface is susceptible to colonisation.
From 'colonisable' (adjective, British spelling) + '-ity' (noun-forming suffix). Combines Latin 'colonia' with the productive '-able' and '-ity' suffixes to create a noun describing potential for colonisation.
Biologists use this term when discussing how microorganisms can settle in different environments—it's also used in microbiology to measure how quickly bacteria can establish themselves on a surface, which matters hugely for infection control in hospitals.
