It has not shown tolerance to anthropogenic disturbance. Scientists have seen this frog between 0 and 1,000 m (0 and 3,281 ft) above sea level.[3]

Scientists have seen the frog in protected places: [Estacion Biologica Beni](/source/Estacion_Biologica_Beni), [Parque Nacional Noel Kempff](/source/Parque_Nacional_Noel_Kempff), [Área Natural de Manejo Integrado San Matías](/source/%C3%81rea_Natural_de_Manejo_Integrado_San_Mat%C3%ADas), Área de Preservação Ambiental Corumbatai, Botucatu e Tejupa, APA das Nascentes do Rio Vermelho, [APA Ilha do Bananal/Cantao](/source/APA_Ilha_do_Bananal/Cantao), APA Morro da Pedreira, APA Piracicaba Juqueri Mirim Area I, APA Pouso Alto, [Estação Ecológica Serra Geral do Tocantins](/source/Esta%C3%A7%C3%A3o_Ecol%C3%B3gica_Serra_Geral_do_Tocantins), [Parque Estadual do Jalapao](/source/Parque_Estadual_do_Jalapao), [Parque Nacional da Chapada dos Veadeiros](/source/Parque_Nacional_da_Chapada_dos_Veadeiros), and [Parque Nacional de Sete Cidades](/source/Parque_Nacional_de_Sete_Cidades).[3]
