Explore the concept of shifting baseline syndrome and its impact on environmental perceptions. Learn about the decline of lamprey eel population, ecosystem impact, and conservation efforts. Discover how this syndrome distorts our view of environmental changes and the importance of conservation and native plant restoration.
Shifting Baseline Syndrome leads to unnoticed environmental changes over generations, affecting wildlife populations.
Understanding historical baselines like the Sacramento San Joaquin River Delta informs ecosystem conservation decisions and restoration efforts.

Shifting Baseline Syndrome in Wildlife Populations
Wildlife populations have drastically decreased over generations without people noticing, exemplifying shifting baseline syndrome. The disappearance of passenger pigeons, salmon abundance decline, and reduced insect presence on windshields are stark reminders of unnoticed environmental changes. Despite clear alterations, these shifts often go unnoticed due to shifting baseline perceptions over time.
The Evolution and Perceptions of Ecosystems
Ecosystems are dynamic and constantly transitioning, as shown in the concept of succession where one ecosystem transforms into another over time. Human intervention like wildfire suppression disrupts natural succession, impacting ecosystem diversity. Understanding historical baselines like the Sacramento San Joaquin River Delta helps make informed decisions for ecosystem conservation and restoration.
Historical Perspectives and Indigenous Stewardship
Indigenous people like the Yurok tribe exhibit deep connections to their land and wildlife, recalling past environmental baselines. The decline of lamprey eels by 90% since the 1960s reflects complex human-nature interactions and shifting baseline challenges. Reclaiming ancestral lands and cultures is pivotal in addressing historical injustices and preserving biodiversity.
What is "normal" or even "natural" in nature? In a world where everything is constantly changing, the human desire to define things as "normal" has broad implications on how we see the world, and how we choose to conserve it (or not conserve it!).
This desire to establish a personal "normal" leads to a quirk of psychology called Shifting Baseline Syndrome.
Learn about the dramatic impacts that it has in this Jumpstart Nature episode.
Join your guide, Griff Griffith, as he explores what shifting baseline syndrome is through some incredible examples. With the help of Dr. Loren McClenachan, Dr. Alison Whipple (San Francisco Estuary Institute), Ben Goldfarb (author and environmental journalist), and Francisco Saavedra Jr (forestry student and member of the Pit River Tribe Madesi band), we look at the many ways that shifting baselines steer us in the wrong direction.
