In my letter, I detail the potential impacts of infectious diseases on amphibian populations; I address common misconceptions regarding the ruling; I discuss ethical issues surrounding amphibian captivity; and I urge for restrictions on the importation and interstate transportation of amphibians.
One threat to California Tiger Salamanders (Ambystoma californiense) is
"genetic pollution". In decades past, Tiger Salamanders (Ambystoma tigrinum)
from the Midwest were transported across state lines and brought to
California. The non-native salamanders breed with the California Tiger
Salamanders and produce hybrids, decreasing successful breeding of pure
California Tiger Salamanders. Photo by SAVE THE FROGS! Ecologist Michael

On March 13, 2016, I submitted a three page letter in support of the recent USFWS ruling restricting the importation and interstate transportation of 201 salamander species (Docket ID: FWS-HQ-FAC-2015-0005). In my letter, I detail the potential impacts of infectious diseases on amphibian populations; I address common misconceptions regarding the ruling; I discuss ethical issues surrounding amphibian captivity; and I urge for restrictions on the importation and interstate transportation of amphibians.

On behalf of SAVE THE FROGS! (www.savethefrogs.com) and our members throughout the USA, I am writing in support of the USFWS ruling restricting the importation and interstate transportation of 201 salamander species (Docket ID: FWS-HQ-FAC-2015-0005).
I am an ecologist with 13 years of professional experience in amphibian
conservation and disease ecology. I spent four years exclusively researching
and authoring original publications on the chytrid fungus Batrachochytrium
dendrobatidis (www.savethefrogs.com/chytrid), a close relative of
Batrachochytrium salamandrivorans. Both of these fungi have been found in
captive amphibians and have been linked to rapid and drastic population
declines in amphibians. I have visited many locations on several continents
where amphibian communities have been decimated by chytrid fungi. Many
streams worldwide are now entirely without amphibians due to the arrival of
chytridiomycosis. There are no known ways to eradicate chytrid fungi from
wild amphibian communities, and many species can be driven to complete
extinction within months of the arrival of Batrachochytrium. Preventing the
spread of Batrachochytrium is the only way known to protect amphibian
populations from its devastating impacts, which have been documented in
hundreds of peer-reviewed scientific publications over the past 18 years.
