The Florida Longleaf Pine Ecosystem Geodatabase A Cooperative Project between the Florida Forest Service and Florida Natural Areas Inventory
2
LPEGDB Purpose Design and populate a spatial database to serve as central repository for information on the distribution and condition of LPEs in Florida
3
LPEGDB Need

3. Goals, Objectives, and Strategies Goal 1: Reliable and accurate inventories and assessments of Longleaf Pine Ecosystems (LPE) on public and private land exist in accessible databases. Objective 1.1: Develop central and accessible repositories of data on LPE collected with standardized methods to facilitate communication and coordination of efforts, to frame the scope of the issue, and to identify sites where land managers and landowners can observe restoration projects at various stages and interact with practitioners to develop realistic expectations for restoration efforts and site potential.
5
LPEGDB Objectives Accessibility to county foresters & land managers Compatibility with regional LPE mapping & other statewide natural resource databases Inform conservation, protection and management priorities for LPEs
6
LPEGDB Project Overview Mar 2012 – Dec 2013; Updates through 2015 4 Major Tasks Compile existing LPE data & identify data gaps Collect LPE field data via Rapid Assessment Integrate existing and new data into LPEGDB Summarize LPE conditions and priorities LPEGDB Existing Data Rapid Assessment LPE Distribution ConditionPriorities

FNAI Natural Community Mapping: 2003 – 2012 Florida Forest Service Longleaf Management Project FNAI Element Occurrence Data FNAI Other Survey Data (rare species, exotics, etc) Red-cockaded Woodpecker Data Florida Cooperative Land Cover USFS Stands LPEGDB Methods Existing Data Initial Data Sources
8
Natural Community Mapping & Ecol. Assessment >60,000 ground-truth points on managed lands > 2 million acres mapped
9
Initial Data Sources Florida Cooperative Land Cover Map Compiled best available local and regional sources Aerial review of critical natural communities: scrub, sandhill, dry prairie, pine rockland, rockland hammock
10
LPEGDB Methods Existing Data Tier 1A – Longleaf Confirmed with Existing Ecological Condition Data Tier 1 – Longleaf Confirmed – High Confidence Tier 2 – Longleaf Confirmed – Moderate Confidence Tier 3 – Longleaf Likely but not Confirmed Tier 4 – Longleaf Possible but not Confirmed Confidence Tier Approx. 8 million acres included as potential LPEs
11
LPEGDB Methods Rapid Assessment 1.8 million acres deployed for Rapid Assessment Focus on presumed intact natural LPE sites
12
LPEGDB Methods Rapid Assessment Assessment design by FNAI & FFS Training by FNAI & FFS Conducted by County Foresters Rapid Field Assessment of Ecological Condition

Rapid Assessment Design
17
Results: Rapid Assessment Areas 79% of confirmed LPE on private lands LPE Occurrence in Rapid Assessment Areas

Results: LPE Condition <50% is at maintain level for many categories Maintain Improve Restore
22
Results: LPE Condition Means for establishing priorities for specific actions
23
Results: LPE Occurrence Occurrence of Longleaf Pine Ecosystems in Florida ~2.5 million acres Confirmed or Assumed LPE
24
Results: LPE Occurrence 4.8 million acres – LPE still unknown Mostly pine plantation Merits further assessment
25
v.2 Recent Updates Added condition data for many conservation lands Compare LPEGDB with other projects: FRA, CSFIAS Held Longleaf Partners Meeting for guidance on future of LPEGDB Integrate data into statewide conservation planning efforts
26
LPEGDB v.2 Summary LPEs confirmed on 2.2 million acres in Florida 76% with ecological condition data 40% on private lands An additional 300,000 acres of Longleaf natural communities identified from aerial photos
27
Next Steps Coordinate criteria and definitions for reporting longleaf acres across the partnership. Develop summaries and map products that could be easily used by individuals with limited GIS knowledge. Give priority consideration to ground cover in ecological condition assessments. Include assessment and distribution of longleaf pine planation in the database. Consider several adjustments to the rapid assessment protocol including metrics for capturing overstory composition, old-growth characteristics, and occurrence of longleaf in strata other than the canopy. Continue working with longleaf partners to enhance the compatibility of LPEGDB with regional efforts and promote similar assessments rangewide.
