The act of completely removing or destroying something in an ongoing or continuous way.
Present participle form of extirpate, created by adding the -ing suffix to the base verb form, following standard English gerund and progressive tense rules.
The -ing form of a verb emphasizes the ongoing process rather than a single completed action—so 'extirpating invasive species' sounds like active, continuous work, which is why conservation scientists use this form to describe their long-term projects.
