Amphibian Declines & Chytridiomycosis


Amphibian Declines & Chytridiomycosis

Amphibians are one of the most threatened groups of animals worldwide. Since 1970, scientists have observed precipitous population declines and outright disappearances of numerous amphibian species. Many of these die-offs have been attributed to a newly-recognized fungal disease known as chytridiomycosis (Batrachochytrium dendrobatidis; “Bd”). Chytridiomycosis caused by Bd is the worst infectious disease ever recorded among wildlife in terms of the number of species impacted and the severity of the impact.

To address this issue, PARC and the Division of the National Fish Hatchery System, along with our partners and sponsors, held a conference on 5-7 November 2007.

The purpose of the 2007 international Bd conference was to:

  • Review what we know about Bd
  • Assess scientific priorities and management needs
  • Identify actions to limit the spread and impact 


The meeting was comprised of presentations by many of the world’s experts on Bd, case studies of Bd detection and management, interactive panel discussions and working groups resulting in action items, and a poster session.
