Statewide Biomass Assessment

Florida Forest Service

Overview

This project was mandated by the Florida legislature in 2012 (House Bill 7117), to evaluate timber resources in Florida with regards to distribution, availability, removals and current utilization on a statewide, multi-county and county basis, identifying areas of over-utilization and under-utilization. The study mapped forestland cover, identified forestland ownership, and analyzed distribution of timber and timber removals of primary wood-using mills in their woodsheds. Standing timber and timber net growth values are based on 2013 FIA data, which is the same date timber removals are estimated for.

Details

This project provided a comprehensive statewide inventory of forest timber resources for the State of Florida using a stratified inventory approach. This approach not only provides overall stocking but also provided the spatial distribution of this information. The primary plot information that was used for the assessment was the U.S. Forest Service’s FIA program. The mapping of forest cover types used remote sensing approaches and leveraged existing available GIS data sets from a variety of sources within Florida. The main mapping imagery source was Landsat Thematic Mapper (TM) imagery, which has a pixel size of 30 meters (m). This sensor is good for detecting changes over large landscapes but can miss smaller gradual changes.

Outcomes

The historic record of Landsat imagery made it appropriate for this analysis and allowed the project to benefit from the work done on federal programs such as the National Oceanic and Atmospheric Administration (NOAA) Coastal Change Analysis Program (C-CAP) which is also based on Landsat data. Results are now available for all stakeholders so that available forest resources are presented in a spatial context statewide.

Project Status: This project began in 2013 and ended in 2016.
