Discover how Landsat data facilitates operational forest management, enabling in-depth analyses to monitor forest health, assess pest hazards, predict productivity, and support decision-making for carbon management. This presentation at Pecora 17 highlights the importance of Landsat in understanding key trends like land use, climate change, and economic shifts. Explore the impact of Landsat imagery on forest ecosystems through monitoring leaf area index changes, stand boundaries, and growth efficiency, ultimately enhancing forest carbon sequestration and ecosystem services. Witness the transition from research models to operational decision support tools for strategic forest management.

Entering a New Landsat Era: Already Operational! Randolph H. Wynne Presented to Pecora 17
Landsat data enable • Operations, not just science • Managing, not just monitoring • Dynamic, not just static, information • Management-scale, not just coarser-scale, analyses
Landsat Importance The Landsat program provides the only inventory of the global land surface over time at a scale where human vs. natural causes of change can be differentiated on a seasonal basis with superb radiometric qualities No other satellite system is capable/committed to even annual global coverage at this scale
Already Operational • While many of us have been working hard to ensure (finally!) operational status of the Landsat program, a large base of users has been relying on the data stream for many years • Examples will be given from the forestry sector

LAI (Leaf Area Index): • stand stratification for inventory • identification of poor-performing stands for early harvest • identification of stands with high levels of competition LAI plus GE (Growth Efficiency) Provides ability to estimate stand-level response to silviculture: (fertilization, release, tillage) Growth = 3.9 tons Growth = 7.2 tons Growth = 5.1 tons

Ecosystem Services • Resources and processes supplied by natural ecosystems • Include, but not limited to, water quality, biodiversity, carbon sequestration
Modeling Ecosystem Services at the Tract Level Using Remote Sensing EcoMetrix is a joint project of the Virginia Department of Forestry, USDA Forest Service, Virginia Tech, and other Commonwealth of Virginia and Federal agencies. EcoMetrix will provide spatially-explicit, web-based quantification of ecosystem services using extant best of breed models at the tract level. Two initial foci are carbon and water quality/quantity; short-term plans for biodiversity

Already Operational • While many of us have been working hard to ensure (finally!) operational status of the Landsat program, a large base of users has been relying on the data stream for many years
What Next? • The mandate we have is bigger than we thought, as Landsat, like the weather satellites, is now a key element of the infrastructure on which our economy and environmental monitoring and management increasingly depend
