Additional Comments:
El hongo quítrido patógeno de la salamandra (Batrachochytrium salamandrivorans, “Bsal”) ha provocado una disminución dramática de las salamandras europeas desde su llegada en 2010 a través del comercio internacional de mascotas (Feldmeier et al. 2016). Si bien la presencia del hongo no ha sido confirmada en América, se está propagando en Europa y corre el riesgo de propagarse aún más. Se cree que la amenaza de infección y disminución de la población de salamandras es muy probable y perjudicial para la mayoría de las especies nativas, en caso de que el hongo llegue a Guatemala.
Se deben tomar medidas preventivas y proactivas para detectar la llegada de Bsal a Guatemala y establecer una línea de base incluyendo el muestreo de salamandras encontradas durante las actividades rutinarias de monitoreo de anfibios en el país.
Es importante enfatizar el potencial daño por el ingreso o introducción de especies de anfibios exóticas e invasoras (especies de la Lista Negra - CONAP) de anfibios a las poblaciones silvestres nativas.

| 5 | Habitat for reintroduction, conservation translocation or supplementation | Does enough well-managed and reliably protected habitat exist, either within or outside of currently protected areas that is suitable for conservation translocation, including population restoration or conservation introduction? | Yes / probably | Reserva de la Biosfera Sierra de las Minas y Biotopo Universitario Mario Dary Rivera para la Conservación del Quetzal |
| 6 | Previous reintroductions | Have reintroduction or translocation attempts been made in the past for this species? | No | |
| 7 | In situ conservation activities | Are any in situ conservation actions currently in place for this species? (Only required if a Red List Assessment has not been completed, or if new actions have been implemented since the last Red List Assessment. (Information from the Conservation Actions section of the Red List assessment should be reviewed and considered when answering this question.). | Yes / probably | Reserva de la Biosfera Sierra de las Minas y Biotopo Universitario Mario Dary Rivera para la Conservación del Quetzal |
| 8 | In situ conservation activities | Are additional in situ conservation actions required to help conserve this species in the wild (e.g. habitat restoration and/or protection, control of invasive species, national legislation etc.)? | Yes / probably | Mejoramiento de la preservación forestal efectiva y el manejo continuo de las áreas protegidas existentes es esencial para la conservación de esta especie. |
| 9 | In situ research | Is additional in situ research required to better understand the species, e.g. distribution, population trends, natural history etc.? | Yes | Se requiere investigación en distribución, estado poblacional, ecología, amenazas y sus efectos sobre la especie |
| 10 | Threat mitigation | Are the threats facing the taxon, including any new and emerging threats not considered in the IUCN Red List, potentially reversible? | Threats unlikely to be reversed in time to prevent further decline / extinction | Deforestación debido a la expansión de la agricultura, específicamente las plantaciones de café, tomate (Taller de Evaluación de la Lista Roja de Guatemala, agosto de 2019) y plantaciones de helechos a gran escala (G. Ruano-Fajardo, comunicación personal, agosto de 2019). ). Mayor frecuencia de incendios forestales debido a estaciones secas más prolongadas y patrones de precipitación más erráticos como resultado del cambio climático. La contaminación resultante del uso excesivo de agroquímicos representa una amenaza adicional (D. Ariano-Sánchez com. pers. agosto de 2019). La minería de níquel puede representar una posible amenaza futura una vez que el área ya no esté protegida por la Universidad de San Carlos (D. Ariano-Sánchez y G. Ruano Fajardo, comunicación personal, agosto de 2019).

Cuando se encuentran, las salamandras son perseguidas en Guatemala porque se cree que son venenosas (Taller de Evaluación de la Lista Roja de Guatemala, agosto de 2019). |
| 11 | Over-collection from the wild | Is the taxon suffering from collection within its natural range, either for food, for the pet trade or for any other reason, which threatens the species’ continued persistence in the wild? | No / unlikely | |
| 12 | Population recovery | Is the known population of this species in the wild large enough to recover naturally, without ex situ intervention if threats are mitigated? | Yes / probably | |
| 13 | Action plans | Does an Action Plan for the species already exist, or is one currently being developed? | No | |

| 15 | Cultural/socio-economic importance | Does the taxon have a special human cultural value (e.g. as a national or regional symbol, in a historic context, featuring in traditional stories) or economic value (e.g. food, traditional medicine, tourism) within its natural range or in a wider global context? | No | |
| 16 | Scientific importance | Is the species vital to current or planned research other than species-specific ecology/biology/conservation within the Order to which it belongs (e.g. Anura, Passeriformes etc.) e.g. human medicine, climate change, environmental pollutants and conservation science? | No research dependent on this species | |
