Wild caribou (rangifer) herds and areas of reindeer husbandry
Distribution and observed trends of wild Rangifer populations throughout the circumpolar Arctic (from The Circum Arctic Rangifer Monitoring and Assessment Network, CARMA). Currently wild reindeer and caribou have declined by about 33% since populations (herds) peaked in the 1990s and early 2000s (3.8 million compared to 5.6 million) which followed almost universal increases in the 1970s and 1980s. In Arctic Eurasia reindeer herding represents a l...

Fish yield and fish sanctuaries, MACH sites
Continous monitoring of fish yields have increased since the MACH project start in 1998, with a more than doubled yield in 2004 compared to 1999. Part of the project has been for the communities to establish fish sanctuaries to enable re-spawning and over-wintering of fish.

Planet index 2007 for marine species population
The Marine Species Population Index provides an assessment of the average changeover time in the populations of 217 species of marine mammals, birds, reptiles, and fish. The index represents the average value of six regional ocean indices. More pronounced declines are seen in the southern oceans, attributed to the fact that major losses and degradation of marine ecosystems in the industrialized world took place prior to 1970.
Marine species are ...
