A report on the "vital signs" of Yellowstone National Park examines the health of wildlife and other resources, such as Grand Prismatic Spring.<\/figcaption><\/figure>\n

A series of reports issued by Yellowstone National Park scientists offer an update the park’s overall “health,” including a look at climate change, wolves, bears, cultural resources and other key issues.<\/p>\n

Yellowstone National Park\u2019s 2013 \u201cNatural Resource Vital Signs\u201d report and annual wolf and bird project reports are now available as tools used to assist park managers and scientists more fully understand the status of important indicators of resource condition, according to a statement released by the park’s public affairs office<\/p>\n

The latest Vital Signs report shows that the greater Yellowstone area may have reached its carrying capacity for grizzly bears, while elk numbers in the park’s northern range may be stabilizing after a decline.<\/p>\n

In the Vital Signs report, park scientists and their cooperators report on data from more than two dozen indicators to study the influences, both inside and outside of the park, that affect Yellowstone\u2019s overall ecological status and the condition of cultural resources. \u00a0Ecological indicators include ecosystem processes such as wildland fire, as well as the status of native species and stressors such as wildlife disease and non-native species.<\/p>\n

This year, several indicators on the status of Yellowstone\u2019s cultural resources were included. \u00a0As the world\u2019s first national park, Yellowstone is home to an incredible collection of over 800 historical structures that help tell the story of transportation, lodging, and park management. The park also contains more than 1,600 known archeological sites that demonstrate evidence of at least 10,000 years of deep human connections with the ecosystems. Hundreds of thousands of historic documents, ethnographic artifacts, fossils, pieces of clothing, souvenirs, and works of art also reside in the park\u2019s museum collections.<\/p>\n

All three reports, published by the park\u2019s Yellowstone Center for Resources, help inform resource management decisions and support ongoing and future research needs.<\/p>\n

Highlights from this year\u2019s Vital Signs report include:<\/p>\n

\u2022 Climate<\/b>: \u00a0Precipitation data suggest that we are still in a long-term drought. \u00a0Recent data support a continued trend of warming with average low temperatures increasing by 4.6 degrees since 1989.<\/p>\n

\u2022 Bears<\/b>: \u00a0Grizzly bear numbers appear to be stable in the GYE this year; supporting recent discussion that bears have reached carrying capacity in the ecosystem.<\/p>\n

\u2022 Wolves and elk<\/b>: \u00a0Elk surveyed along the northern range of Yellowstone continued to decline as a result of multiple factors, but show signs of stabilizing at a new low. \u00a0The number of wolves that spend most of their time in Yellowstone declined slightly.<\/p>\n

\u2022 Bison<\/b>: \u00a0The conservation of Yellowstone bison continues to be successful with population number s over 4,000 bison.<\/p>\n

\u2022 Historic structure conditions and archeological sites<\/b>: \u00a0Historic structure assessments of the 880 buildings, roads, bridges, and grave markers have been completed for 80 percent of the sites. \u00a0About 77 percent of historic structures and 65 percent of known archeological sites are in \u201cgood\u201d condition.<\/p>\n

\u2022 Native fish<\/b>: \u00a0There are signs that the number of Yellowstone cutthroat trout in Yellowstone Lake is increasing. \u00a0Efforts to reduce the population of non-native lake trout have resulted in the removal of over 1 million lake trout from Yellowstone Lake.\u00a0Artic grayling and westslope cutthroat trout restoration efforts began in 2013 as part of the native fish preservation effort.<\/p>\n

The 2013 Vital Signs report<\/a> can be found online along with reports from the wolf<\/a> and bird<\/a> programs.<\/p>\n
