The Bulgarian Biodiversity Portal is a part of the global information exchange network established by the Convention on Biodiversity (Clearing House Mechanism - CHM). Its purpose is to offer directly or provide links to the information on biodiversity you need.
Networks and web portals provide systemized access to vast amount of information, which often comes from a variety of sources. Thus they are kind of crossroads in the Internet space making the search and access to information and the navigation easier. The links to such networks and web portals listed here are organized in four parts: global, European, national and thematic.
