In recent years Batrachochytrium dendrobatidis has expanded around the planet. Years ago we started the Bd-maps project, in which, through the internet, it is possible to see the global distribution of the pathogen and the affected amphibian species. Unfortunately, the new species described recently, Batrachochytrium salamandrivorans, probably will follow the same path, and sooner than later, will end up reaching much of the world.
Regarding infectious diseases, as soon as we detect its arrival to a particular area, the sooner we are able to establish initiatives to protect the amphibians from decline or extinction. Therefore, the contribution of everyone can be invaluable, and presently there exists several ways in which each person can help with this task.
One example of a citizen science initiative is the new project “Saving Salamanders with Citizen Science,” that tries to gather information about salamanders and newts found dead or sick. The project is an initiative of an iNaturalist promoted by ACA & ASG (Amphibian Specialist Group & Amphibian Survival Alliance), which you can access here. If you find a dead newt or salamander, or with symptoms of illness (skin lesions, lethargy…), take a photo and upload it with the following information: date, location, species (if possible), number of animals that are dead or with symptoms, and possible alternative of death (as it may be different from the illness, like predation or a road accident).
In the case of ranavirus, which as we mentioned already has caused havoc in the north of Spain, there also exists similar initiatives. The “Global ranavirus reporting system” initiative, has been launched by a consortium of scientists to document new outbreaks worldwide, even though it is oriented more towards researchers than to society in general.
