PJ Woodland in winter

PJ woodlands in a changing climate webinar series- Recordings available

Webinar recording for Day 1
Webinar recording for Day 2.

Climate change in the Great Basin poses many challenges to land management. This webinar series will discuss recent research and observations of climate and drought-driven changes in pinyon-juniper woodland dynamics. Tune in to better understand what changes may be in store. These one-hour webinars will begin at 11 PST/12 MST.

Day 1: Recent Pinyon-Juniper Responses to Climate Change
Great Basin pinyon-juniper responses to climate change: Woodland expansion, contraction, or transformation? – Peter Weisberg, UNR
PJ woodland management changes after two decades of drought: Perspective from Four Corners – Ian Barrett, BLM
Q&A and discussion

Day 2: Understory Response and Management Implications
Fire impacts in pinyon-juniper woodlands: Recovery, plant invasions, and restoration opportunities – Ali Urza, USFS
Anticipating future climate-driven changes in pinyon-juniper woodlands – Bob Shriver, UNR
Q&A and discussion

Episodic occurrence of favorable weather constrains recovery of a cold desert shrubland after fire

View article.

This study demonstrates the importance of episodic periods of favorable weather for long-term plant population recovery following disturbance. Management strategies that increase opportunities for seed availability to coincide with favorable weather conditions, such as retaining unburned patches or repeated seeding treatments, can improve restoration outcomes in high-priority areas.

Sagebrush recovery patterns after fuel treatments mediated by disturbance type and plant functional group interactions

View article.

Treatments in cooler and moister woodland sites had more positive effects on sagebrush recruitment and perennial grass cover, less negative effects on sagebrush intraspecific interactions, and smaller increases in annual grass cover indicating potential increases in resilience to fire. In warmer and drier invasion sites, reductions in woody fuels resulted in lack of sagebrush recruitment, disruption of sagebrush intraspecific interactions, and progressive increases in annual grass indicating reduced resilience to fire and resistance to invaders.
