Overview of iTree Software Tools Michael Knapp Director, Urban Forest Management Division Fairfax County, Virginia michael.knapp@fairfaxcounty.gov 703-324-1729
Overview of Overview iTree Software Suite • UFORE • MCTI • SDAP • On-line Resources
UFORE UFORE • Urban Forest Effects Model • Developed by USDA Forest Service's Northeastern Research Station • Calculates: • structure • environmental effects • values
UFORE UFORE • Allows users to collect data an urban forest • And to estimate ecosystem services that resource provides
Hmmm…sounds like STRATUM! • Similarities • Similar outcomes • Structure, function, value • Implications for management • Similar goals • Advocates for management/conservation • Differences • Different tree populations • STRATUM: focus on street trees • UFORE: focus on the whole urban forest
UFORE – What can it be used for? • Benchmark structure • species composition • number of trees • tree density • tree health, etc • analyzed by land-use type • Quantify air quality benefits • Hourly VOC emissions • Impact on ozone/CO formation • Carbon storage/sequestration • Effects of trees on building energy use and consequent effects on CO2 emissions from power plants.
UFORE – What can it be used for? • Compensatory values $$$ • air pollution removal • carbon storage and sequestration • Tree pollen allergenicity index • Potential impact of forest pests • Gypsy moth • Emerald ash borer • Asian longhorn beetle
UFORE - application • Can be used on complete populations • Statistically based sampling and data collection protocols for large areas
UFORE - data collection and process • More complex than STRATUM • structural / health components • Limits use of volunteers • Data collection more suited to professionals • Customizable PDA Utility can be used to collect plot data • Merged with local weather and air pollution concentration data. • Data transferred through “shell” to US Forest Service for processing • Customized reports returned to user
MCTI • Mobile Community Tree Inventory • David V. Bloniarz, USDA Forest Service • Designed as a basic tree inventory application • Allows communities to conduct tree inventories and to produce summary reports at various levels of detail and effort • Not meant as substitute for more robust commercial products
MCTI MCTI • Three-tiered inventory system enables users to select a level of use that matches their needs and comfort level: • paper inventory tally sheet • desktop application for inputting collected data • fully computerized system incorporating desktop software and i-Tree's PDA Utility
MCTI • Variable inventory protocols • Maintenance • Risk tree • Utility work • PDA Utility data can populate STRUTUM • Easy to use… ideal for volunteers • Inexpensive!
MCTI –Inventories and Uses • Profile species composition of urban forest • Analyze condition of individual trees and of the entire forest • Record information about significant trees • Monitor planting success rates • ID high-risk/hazard trees • Identify budget needs • Build public support for protecting and expanding urban forests • STRATUM
SDAP • Storm Damage Assessment Protocol • Standardized method to assess widespread damage immediately after a sever storm • FEMA funding • Easy and accurate estimate of: • Tree storm damage • Costs for recovery
SDAP Process Overview • Start with Emergency Planning • Tree Emergency Plan Worksheet • Pre-storm setup • Create random sample segments • Measure tree density and size class within and 50 feet outside of ROW • Finalize Pre-storm report • Store for future storms
Reference data • Tiger Line Data can be used for generating random segment samples • 2% of blocksides • Trees 10 minimum, 30 maximum per block • Recommended that data collection be conducted by professional foresters/arborists
SDAP Data Processing • Data collection • Paper forms • PDA • Desktop Interface • Manage Users • Community Values • Reference Data • ROW Info • Export Data
Post-storm work • Revisit sample segments • Debris: choose estimation method • Indirect by average crown loss class • Direct as Cubic Yards of debris • Trees within ROW • Hazard pruning by size class • Hazard removal by size class • Enter data, report results • Check in mail!
SDAP Validity • Tested for ice storms • Low variance • 2% sample got within 5% of true value in field test • Not tested for wind storms • Larger variance • May affect required sample size
