Step 1 A Tree Inventory • Have the data to make informed decisions Urban and Community
Why Conduct a Tree Inventory? • To know more information about the existing trees and to further tree management and planning Urban and Community
Types of Inventories • Street and park tree inventory • Problem tree inventory- hazard tree and all ash inventory • Sample or partial tree inventory – systematic sampling techniques • Canopy cover inventory – Li. DAR and land cover data Urban and Community
Who will Complete the Inventory? • • • Contractor City staff Interns or students Volunteer groups or Tree Board The Iowa DNR – if under 5, 000 population Urban and Community
What to Include in the Inventory • • • Tree Number Species Size Condition Location (address or GPS) Urban and Community
Step 2 Planning • Making Management Decisions Urban and Community
Tree Ordinance • Revisit the nuisance section of the tree ordinance • Opening up tree ordinance can risky or an opportunity Urban and Community
Public Safety Urban and Community
Quarantines • Regulated articles may not be moved from the regulated area to an unregulated area of the state unless one of the following is met: – an USDA APHIS PPQ limited permit, or certificate, has been issued and attached to the regulated article in accordance with USDA provisions Urban and Community
Quarantine Regulated Articles included in this order (cont): • Green (non-heat treated) ash lumber with either bark or the outer one-inch of sapwood, or both, attached. • Non-coniferous (hardwood) wood chips and nonconiferous (hardwood) bark chips larger than 1 inch in two dimensions. • Any article, product or means of conveyance when it is determined by the State Entomologist to present the risk of spread of the emerald ash borer.
