The marine LPIshows a decline of 39 per cent between 1970 and 2010 (Figure 14). Thisis based on trends in 3,132 populations of 910 mammal, bird, reptileand stability throughout the time period. The period from 1970 throughsome stability, until another period of decline in recent years.Although the overall picture shows a declining trend, marinepopulation trends differ across the globe. Some increases have beenrecorded among populations in the temperate oceans, particularlypopulations recovering from long-term historical declines (Thurstanet al., 2010; Lotze et al., 2011).The sharpest declines in marine populations have beenobserved in the tropics and the Southern Ocean. Species in declinespecies showing declines are many shark species, which have sufferedIn the Southern Ocean, declines have been observed amongin this area, including both reported and illegal or unregulatedand petrels have also been under threat from the rising presenceis causing declines in population numbers and threatening somespecies, such as the iconic wandering albatross (Diomedea exulans)Figure 14: The marineLPI – shows a declineof 39 per cent between1970 and 2010This is based on trends in3,132 populations of 910mammal, bird, reptileZSL, 2014).KeyMarine LivingIndex Value (1970 = 1)2101970 1980 1990 2000 2010YearChapter 1: The State of the planet page 23
