pnw research station s plan for urban inventories
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
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
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
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
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
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

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
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
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
rm research station s fia support of new mexico inventory
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
