Hugh Safford, a forest ecologist at UC Davis, discovered a record-setting Jeffrey pine tree at an unexpectedly high elevation in California’s High Sierra.
The Jeffrey pine was found at an elevation of 12,657 feet, surpassing the previous highest-known elevation for this species.
The shift in tree ranges to higher elevations is attributed to global warming, with the changing climate making previously inhospitable areas suitable for plant growth.
The spread of trees to higher altitudes may be facilitated by birds like Clark’s nutcrackers, which help transport seeds uphill.
Similar high-elevation Jeffrey pines have been observed in the Sierras, indicating a broader trend of trees expanding their ranges upwards.
While trees are adapting to higher elevations, they are also facing challenges in their traditional habitats as they struggle to keep pace with changing environmental conditions.
Hugh Safford's on-ground research underscores the importance of direct observation in understanding the impact of climate change on ecosystems.
The discovery of the record Jeffrey pine highlights the effects of climate change on plant species distribution, with trees moving uphill to survive.
