Fire‐Injured Trees: Predicting Mortality and Assessing Hazard

Fire‐Injured Trees:
Predicting Mortality and Assessing Hazard

October 16, 2019, Wednesday
9:00 a.m. to 5:00 p.m.

Details and Registration

In the aftermath of fires, professionals are often asked to assess the health of trees within private and public lands. But making decisions on the health and probability of mortality in fire‐injured trees can be complicated. There are many factors to assess and this workshop will present information to aid in the assessment of the health of trees after a fire, particularly California native conifers and oaks. The workshop will begin with brief classroom presentations discussing types of fire‐related injuries, how to determine if a tree will survive fire related injuries, insect activity post‐fire, post‐fire decay and the potential hazards of decay. Following the classroom presentations the workshop will proceed to a field site within the Camp Fire burn scar to examine fire‐injured trees and continue the discussion on how to assess hazard and predict tree mortality.

Time, Place, and Registration
This workshop will be held from 9:00 a.m. to 5:00 p.m. on Wednesday, 16 October 2019, and will begin with classroom instruction in Room 129 Holt Hall, on the Chico State University Campus and will continue with a field site visit in the Camp Fire burn area. The registration fee is $110 personal, $130 business, $100 for members of Friends of the Herbarium, and $50 student (only 2 seats available at the student price). You must register in advance, using the form on the next page. Class size is limited to 30 participants; class will be cancelled on 4 October if there are not at least 15 registered participants. For information about registration or to register using credit card please contact the Biology office at or (530) 898‐5356. For more information about workshop content please contact the instructor.

What to bring: Bring a hard hat and water. It is also recommended to bring a sack lunch (there will only be a short break before travelling to the field site).

During his time working for the USFS he has studied post‐fire bark and woodboring beetle activity and snag fall rates of fire‐killed trees. He has also developed the fire‐injured tree marking guidelines and hazard tree guidelines for the USFS Pacific Southwest Region. Danny’s primary fields of interest are bark beetle ecology, forest stand dynamics and fire ecology. His email is:
