THE ANGORA FIRE: WHAT WILL BE THE

FUTURE FOREST?

A Workshop Presented by

University of California Cooperative Extension

Lake Tahoe Community College

November 3, 2007

Workshop Objectives

Provide information to Lake Tahoe residents and resource managers that

will enable them to anticipate how the vegetation in the area affected by the

Angora fire will look over time.

Describe potential management actions that could be used for ecological

restoration in the burned area.

Use empirical evidence from other burned areas and vegetation simulation

tools to predict outcomes of different management actions.

Describe monitoring activities underway or planned to evaluate the

effectiveness of management activities in preventing environmental

degradation and achieving restoration.

Format

Please hold your questions until the end of each

presentation.

Questions that cannot be answered on the spot will be

recorded and referred to the appropriate agency or

individual to be answered later.

Responses to questions will be sent to participants by e-

mail and posted on the El Dorado County Cooperative

Extension website http://ceeldorado.ucdavis.edu/

Pre-Fire Fire Threat

Page 10: THE ANGORA FIRE: WHAT WILL BE THE FUTURE FOREST? · Angora fire will look over time. Describe potential management actions that could be used for ecological restoration in the burned

Fire behavior was driven by extremely

high winds and extremely low fuel moisture.

More than 2400 acres burned within

the first several hours after ignition.

What will happen in forest stands that

are entirely dead and will not be logged?

Or, on sites that were salvage logged?

Questions to ConsiderIf the goal is to restore the burn to a desired vegetation mosaic as

quickly as possible:

• What are the pros and cons of removing dead trees (while providing thenumber of wildlife snags required by the Sierra Framework and otherpolicy)?

• Will natural regeneration achieve forest restoration? If not, why?

• Is it desirable to plant and if so, what would be the ideal plantingprescription (number of trees/acre, species, size of stock, time ofplanting)?

• What practices can or should be used to ensure survival and optimalgrowth of planted trees?

• Once established, what management practices should be applied to theregenerated forest to accelerate achievement of pre-fire forestcomposition and structure?
