Burton's legless lizard "L. burtonis" is not a priority for conservation as it is Australia's most widespread reptile and inhabits almost all Australian habitat types with only a few exceptions. In addition, it is not known how abundant Burton’s legless lizard is, but there has been no indication that this species is rare or rapidly declining. Consequently, while Burton’s legless lizard has not been assessed for an IUCN conservation status yet, it is predicted with a fair degree of confidence that it would be given the status of "least concern".
