PNW Research Station’sPlan 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
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
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) • California 689 • Hawaii 25 + (5 Maui urban clusters) • Oregon 66 • Washington 190
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 localarborists complete Hawaii winter 2011
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
FIA Urban Plot Layout • 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 2 Subplot: 24.0 ft. radius Azimuth 1-2 = 360º Azimuth 1-3 = 120º Azimuth 1-4 = 240º Distance between Subplot centers is 120.0 ft. horizontal 1 3 4
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)
Tree Attributes • Damage to tree • Urban • Natural • Diseases • Insects • Urban restrictions • Sidewalks • Power lines • Crown condition • Size and shape • Transparency • Density • Dieback • Poor maintenance
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
Finally, working in urban areas and obtaining permissions require excellent people skills
RM Research Station’s -FIA supportof 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
