Urban FIA Data-- FIA core variables General stand and site characteristics Tree and sapling measurements, health, and condition Seedling data Derived estimates of volume, biomass, carbon, area change, growth, removals, and mortality Condition: reserve status, ownership, land use, forest type, stand size and age, land cover, canopy cover, physiographic class, forest type, treatment, disturbance Tree: spp, dbh, height, tree class, grade, tree status, standing dead, decay class, mortality and year, cause of death, crown class, uncompacted and compacted crown ratios, damages, rotten and missing cull

Urban FIA Data-- FIA urban additions Condition: land use (delineating among nonforest land uses) i-Tree land use (to cross walk between FIA and i-Tree LU) Subplot-condition: percent cover of tree/sapling percent cover seedling/shrub percent surface cover: buildings, impervious, permeable, herbaceous, water (sums to 100%) Tree: spp (larger list) crown data (light exposure, dieback, diameter and foliage absent) urban damage agents (stem girdling, bark inclusion, severe topping or pruning, excessive mulch, conflict with root, with crown, improper planting) tree use variables (riparian tree, maintained tree, street tree) building azimuth and distance (trees>20” )
