Great Bustard Memorandum of Understanding for governments, scientists, conservation bodies and others to monitor and coordinate conservation efforts. These efforts need to focus on active habitat management and on maintaining large areas of non-intensive farming systems. The MoU only covers the middle-European populations of the great bustard ("Otis tarda"). Several remnant great bustard populations that can be found in, inter alia, Spain, Portugal, Morocco, Russia, Turkey, Kazakhstan, China and Mongolia are not included. All signatories shall endeavour to work closely together and with appropriate international organizations to improve the conservation status of the great bustard throughout its breeding, migratory and wintering range. Therefore, they shall:
Edwardsiella tarda along with maintaining suitable sanitation of water. Other stress factors include drastic changes in temperature, pH, and dissolved oxygen levels in the water. In order to manage properly for edwardsiellosis water must be checked constantly in order to keep fish stocks completely free of pathogens. Some of the most recent research done on "Edwardsiella tarda" was performed by Griffin et al. (2013) to assess what the literature refers to as "the intra-specific variability of "E. tarda" isolates from 4 different fish species in the eastern United States." These intra-specific variations that they were looking for occur in other parts of
