DAMAGE DETERMINATION TO TREES FROM DEER
1. What is a tree/shrub worth? The Iowa DNR states that the wood from a mature walnut tree is worth as much as $20,000, which equals about $200 per growing year. Other value shows that a tree produces up to $55,000 of value during its lifetime. This is from cleaning the air, preventing erosion, reducing solar temperatures, sequestering carbon and energy conservation. Trees/Shrubs also provide food, medicinal drugs, fuel, and wood which is the principal building material in the world.
2. What is a deer worth? The Iowa DNR at certain times allows landowners to remove deer (state sanctioned hunting) for the price of $0 to $28. But if a deer is removed without a deer tag, the value of the deer is $1500 or more per deer , according to the Iowa DNR, unless you are protecting your property.
3. On March 19th 2007, Mr. Greg Harris, Iowa Depredation biologist while under oath in a court of law was asked how he determined the damages to trees caused by deer. He stated we go by whatever the landowner says his trees are worth.
Deciduous, Evergreen, Shrubs and Fruit Trees Damage from Deer
-Browsing spring-summer: If the terminal leader or 25% of the leaves or fruit within 5 ft of the ground are eaten, the damage will be $150 per tree.
-Browsing - winter: If the terminal bud or 10% or more of the buds or foliage are eaten off within 5 ft of the ground the damage will be $150 per tree.
-Death of plant from browsing will be $1500 or more per tree.
Fall buck rubs: If 25% or less of the circumference of the stem has had its bark removed the tree shall be considered damaged with a value of $150. If 26% or more of the circumference of the stem has had its bark removed or the tree is broken off it will be considered a total loss and the value will be $1500 or more per tree.
Damage to the terminal bud, browsing over 25% of the side branches or fall buck rubbing that makes the tree unsellable. All will be considered a total loss. Worth will be determined at full retail value.
IF A DAMAGED OR KILLED TREE OR SHRUB IS REPLACED AND PLANTED BY THE STATE OF IOWA WITH A PLANT OF EQUAL SIZE AND VARIETY THERE WILL BE NO VALUE LOSS.
