Section 63-1705, Idaho Code
01.
Forestland Valuation Process. The process used to determine the forestland value under the
productivity option will be as specified in the User's Guide referenced in Section 63-1701, Idaho Code.
(7-1-24)
02.
Forest Valuation Zones. The state will be divided into four (4) forest valuation zones:
(7-1-24)
a.
ZONE 1 - Boundary, Bonner, Kootenai counties.
(7-1-24)
b.
ZONE 2 - Benewah, Shoshone, Latah, Clearwater, Nez Perce, Lewis, Idaho counties.
(7-1-24)
c.
ZONE 3 - Adams, Valley, Washington, Payette, Gem, Boise, Canyon, Ada, Elmore, Camas, Blaine,
Gooding, Lincoln, Jerome, Minidoka counties.
(7-1-24)
d.
ZONE 4 - The remaining nineteen (19) counties.
(7-1-24)
03.
Classification of Forestlands. In all forest valuation zones, there will be three (3) separate
productivity classes of forestland: poor, medium, and good. These broad classes are related in the following manner
by definition to the "Meyer Tables" published in "Yield of Even-Aged Stands of Ponderosa Pine" and "Haig Tables"
published in "Second-Growth Yield, Stand, and Volume Table for the Western White Pine Type" as both documents
are referenced in Rule 003 of these rules. These classes apply to forestland which may or may not be stocked with
commercial or young growth timber.
(7-1-24)
a.
Poor productivity class is defined as forestland having a mean annual increment, MAI, of one
hundred twenty-five (125) board feet per acre per year, based on a seventy-three (73) year rotation. This productivity
class includes western white pine site index 35-45 and Ponderosa pine site index 45-80. One hundred twenty-five
(125) board feet per acre MAI will be used in the valuation process.
(7-1-24)
b.
Medium productivity class is defined as forestland having a mean annual increment, MAI, of two
hundred twenty-five (225) board feet per acre per year, based on an sixty-eight (68) year rotation. This productivity
class includes western white pine site index 46-60 and Ponderosa pine site index 81-110. Two hundred twenty-five
(225) board feet per acre MAI will be used in the valuation process.
(7-1-24)
c.
Good productivity class is defined as forestland having a mean annual increment, MAI, of three
hundred fifty (350) board feet per acre per year, based on an sixty-three (63) year rotation. This productivity class

includes western white pine site index 61 and above and Ponderosa pine site index 111 and above. Three hundred
fifty (350) board feet per acre MAI will be used in the valuation process.
(7-1-24)
d.
For forest valuation zones 1 and 2, forestland will be stratified into areas of similar productive
potential using the habitat typing methodology described in "Forest Habitat Types of Northern Idaho: A Second
Approximation," referenced in Rule 003 of these rules. Within these stratified areas, site index trees will be selected
and measured that will identify the site index to be used to place the land in one (1) of the three (3) productivity
classes listed above.
(7-1-24)
e.
For forest valuation zones 3 and 4, the criteria for stratification will be generally the same as that
used in zones 1 and 2 based on the habitat typing methodology described in "Forest Habitat Types of Central Idaho,"
as referenced in Rule 003 of these rules, with the following adjustments made in growth rates for lower moisture
levels;
(7-1-24)
i.
For poor productivity class, one hundred twenty-five (125) board feet per acre MAI will be used in
the valuation process;
(7-1-24)
ii.
For medium productivity class, two hundred thirteen (213) board feet per acre MAI will be used in
the valuation process; and
(7-1-24)
iii.
For good productivity class, three hundred twenty (320) board feet per acre MAI will be used in the
valuation process.
(7-1-24)
04.
Deficient Areas. Lakes, solid rock bluffs, talus slopes, and continuously flooded swampy areas,
larger than five contiguous acres in size which can be identified through remote sensing will be valued at forty
percent (40%) of the poor bare land value as defined in Section 63-1706, Idaho Code. These areas are defined as
being incapable of growing trees.
(7-1-24)
05.
Reclassification of Forestlands. Except as provided in Subsection 962.06 of this rule, no parcel's
productivity classification can be changed from the classification as of January 1, 2016, until requirements for
landowner notification, inspector qualifications, and document retention have been met.
(7-1-24)
a.
Landowner notification. Notice of intent to change classification must be provided in writing to the
landowner of record or their designee within two (2) weeks of any determination by the county assessor of intent to
change classification. Such notice must be provided no later than the first Monday in November for the change to be
in effect during the following year. Notice may be delivered in person or by U.S. mail, or, if agreed to by the assessor
and the landowner, by electronic mail. Notice of intent to change classification includes:
(7-1-24)
i.
A statement of intent to change the classification;
(7-1-24)
ii.
A statement of the present classification and the intended new classification;
(7-1-24)
iii.
A statement that the intent notice is not an assessment notice and that the assessment notice will be
sent by the first Monday in June in the following year;
(7-1-24)
iv.
A statement that both the assessed value stated on the assessment notice and the classification may
be appealed to the county board of equalization as provided in Section 63-501A, Idaho Code; and
(7-1-24)
v.
Contact information indicating assessor's office staff who may be contacted and how to do so.
(7-1-24)
b.
Inspector qualifications. The inspector is the person assigned by the county assessor to review
property characteristics and complete a timberland classification form provided by the Tax Commission. The
inspector must be proficient in each of the following:
(7-1-24)
i.
Navigating forest locations;

be retained for no less than ten (10) years following classification determination. Documentation will include, but is
not limited to:
(7-1-24)
i.

coordinates;
(7-1-24)
iii.

962.03 of these rules, and plot locations used in the determination of productivity class; and
(7-1-24)
iv.
Any imagery used to assess the parcel prior to field review.
(7-1-24)
06.
Alternate Method to Establish Productivity Classification. Provided the county assessor and
forestland owner agree and the data is deemed by the county to be acceptable and accurate, the data used to establish
any parcel's productivity classification may be provided by the forestland owner. In this case, inspector qualifications
and proficiency provisions of this rule will not apply.
(7-1-24)
a.
Data to be considered confidential. When productivity data is provided to the county by the
forestland owner, it will be deemed confidential financial information and not subject to public disclosure, as
provided in Rule 004 of these rules.
(7-1-24)
b.
Inspector certification not required. When the alternate method described in this section is to be
used, the county will not be required to have a certified inspector to review property characteristics.
(7-1-24)
c.
Acceptable classification. To be considered acceptable, the classification of the timberland so
established must result in market value for assessment purposes as defined in Section 63-1705(3), Idaho Code.
