PNW Research Station’s Plan for Urban Inventories Partially funded with stimulus grant Cooperative Agreements –Oregon Department of Forestry (ODF) –California Polytechnic State University ODF Has coordinating role among 5 states PNW –FIA and ODF will coordinate training and QA 1

Urban Inventory Objectives Establish plots on the Base FIA Plot Grid Collect Baseline Urban Tree Data Make Data Available To UFOR at Syracuse Analyze Data Locally and Publish Findings Create Jobs 2

Number of Plots by State Urbanized Areas: 2000 U.S. Census definition of 500 people per square mile with census population of at least 50,000: Alaska 11 + (6 Anchorage, 8 Fairbanks urban clusters) California689 Hawaii 25 + (5 Maui urban clusters) Oregon 66 Washington190 3

PNW Urban Inventory Timeline 2010 Train production crews (OR, AK, CA) Quality assurance/control emphasis Start California Start and complete Oregon and Alaska 2011 Train crews (HI, WA, CA) Quality assurance/control continues Crews complete remaining California plots Crews start and complete Washington With local arborists complete Hawaii winter

Urban Inventory Approach Work to be done by contractors, Cal Poly students ODF and Cal Poly will administer contracts Urban (only) manual under development (PNW-ODF) Hand held data recorders—modified ver. of MIDAS 5

FIA Urban Plot Layout Distance between Subplot centers is ft. horizontal Subplot: 24.0 ft. radius Azimuth 1-2 = 360º Azimuth 1-3 = 120º Azimuth 1-4 = 240º 4 Subplots: 24 ft. radius subplots add to 1/6 acre Center of subplot N1 is GPS referenced Data obtained for all trees ≥ 1.0” DBH 6

Subplot Attributes Subplot: Ground Cover by Type Percent maintained (mowing, weeding, herbiciding, etc.) Pct cover by attribute (buildings, permeable, herbaceous, etc.): Tree cover Shrub and seedling cover Low herbaceous Building proximity data (energy) 7

Plots with no trees are also established 8

Tree Attributes Damage to tree Urban Natural Diseases Insects Urban restrictions Sidewalks Power lines Crown condition Size and shape Transparency Density Dieback Poor maintenance 9

Data Analysis Topics Document dist’n, cover, and health of tree species Tree crown health and incidence of disease Incidence of exotics, offsite, or invasive species Potential hosts for diseases present Percent ground covered by impervious surfaces 10

Finally, working in urban areas and obtaining permissions require excellent people skills 11

RM Research Station’s -FIA support of New Mexico Inventory New Mexico received stimulus funding to collect data on P2 plots in 3 out of 10 panels Additional FIA support role –Pre-field logistics –Measure all P3 plots –QA procedures on P2 plots –Collect 1 additional P2/P3 panel 12
