Description:

There is little detailed information about landscape-scale fire patterns and vegetation development after severe fire in pinyon-juniper woodlands of the Southwest. By studying vegetation patterns from a chronosequence of severe fires that have occurred from the mid-1800s until the recent present, we hope to answer the following research questions: 1) Have historical fire regime parameters, such as fire severity and extent, recently changed on this landscape? 2) What factors influence rates of pinyon and juniper tree regeneration after fire? And 3) Do these factors vary with time? By answering these questions, we hope to increase our understanding of pinyon-juniper ecosystem dynamics and resilience to major disturbance. Results from this study are intended to help inform management decisions for this important forest type.

Images showing woodland recovery after severe fires that occurred 3 years (A), 30 years (B), and about 90 years ago (C). Note the changes in shrub and tree occurrence as well as remnant dead tree structures left after the fires.
