A Geospatial Approach for Managing Public Lands in the Face of Climate Change ESRI Federal User Conference 2012 Bo Wilmer

Climate Change and National Forest Management National Forests must address Climate Change under new planning rule – but HOW? • Geospatial analysis can inform much, but not everything. • Landscape managers must recognize uncertainty and adopt an experimental design. • This experimental design can be informed by geospatial analysis.

Geospatial Analysis can inform MUCH… But not ALL. • What we know: • How to document, monitor and map trends. • How to map impacts and visualize scenarios.

• What we don’t know: • How to render forecasts at management scales. • The effects of human management. • What we don’t know.

What we don’t know: Global effects at local scales • Real landscapes are influenced by natural and human disturbance. • This is where management decisions are made.

So even if the landscape does look this way… How should we manage it?

This is an example: • Not intended to represent comprehensive assessment In this instance, we are balancing objectives between community wildfire protection and fisher habitat assuming there will be more fire across the landscape.

What we don’t know: What works

We need to address uncertainty and adopt an experimental design to learn what works.

Designing a solution for land management • Don’t avoid downscaling, BUT recognize limitations. • Rely on intuitive assumptions about data that are mappable. For example: 1. 2. 3. 4.

Increased fire requires efficient, spatial, fire planning. More rain-on-snow events mean increased flooding, and the need for floodplain mapping and preparedness. Habitat pressure upslope and northerly The need for Connectivity. What is currently vulnerable, will be.

• Address uncertainty explicitly – apply a diversity of approaches © 2011 Critigen
