Steve Norman of the US Forest Service- Southern Research Station, Eastern Forest Environmental Threat Assessment Center discusses integrating phenology into cross-scale risk assessments of climate change. He examines climate change and the leaf phenology of trees in the southeastern U.S., specifically at the start of the season. He looks at patterns of greenup and the relationship between wildfires and climate. The presentation includes phenology data, statistics on wildfires and Palmer drought index. The information can be applied in an integrated risk-based model for planning and management.

You should gain an understanding of:

Leaf phenology as an indicator of vegetation change, disturbance, and climate change.

How climate variation acts as a driver of phenology in the Southeastern U.S.

Wildfires and risk assessment.

How climate, phenology, and wildfire are related.
