A Historical Review of Forest Property Taxes in
Pennsylvania: Implications for Special
Forestland Tax Programs

ABSTRACT: Since the late 19th century, many states have offered tax relief to forest owners. Pennsylvania
has had three special forest tax programs. The first, passed in 1887, was a rebate to forest landowners and was
intended to slow forest exploitation. In 1906, a county court ruled that the rebates violated the state’s
constitution. In 1913, the state passed a yield tax law to encourage second-growth timber management. In 1939,
this tax was also declared unconstitutional. Regardless of their constitutionality, few acres were ever enrolled
in either program because of administrative barriers to participation, landowners’ fears of giving up too much
control of their land, lack of publicity, and lack of clear benefits to landowners. The current law, passed in 1974,
allows for current use assessment for farm and forestland. This program, known as Clean and Green, is
intended to protect open space. Although there were 2,350,123 ac of forestland in 29 counties enrolled in the
Clean and Green program in 2000, and in spite of changes made in the late 1990s, concerns remain about the
effectiveness and fairness of the program. Attempts to modify both past and current programs have failed to
address the program’s most significant problems. Perhaps it is time to rethink our entire approach to forestland
taxation. North. J. Appl. For. 20(2):53–60.

Until the mid-19th century, forests were abundant in Penn-
sylvania, and timbering was minor. By the turn of the 20th
century, however, only 20% of Pennsylvania’s original 27 to
28 million ac of forest remained. About half (14 million ac)
had been cleared for agriculture, and heavy timber harvesting
accounted for the rest (Wirt 1904). In 1860, Pennsylvania led
the nation in lumber production. The state remained a major
producer until about 1910, when it dropped to 15th in the
nation as the state’s supply of mature timber shrank. Today,
Pennsylvania’s forests have made a remarkable recovery: the
state is one of the nation’s top hardwood producers and over
60% of the state is forested. Pennsylvania has had three
different special forestland tax programs. What role did these
programs play in the overcutting and subsequent recovery of
Pennsylvania’s forests? What lessons can we draw from
these experiments in forest taxation? To what extent do the
current special forest taxes ensure the conservation of the
state’s private forestland? Do special property tax programs
have unintended consequences that policymakers should be
concerned about? This article addresses these questions

through a review of the history of forest property tax policies
in Pennsylvania.
Property taxes are an important source of revenue for
counties, schools, and municipalities. In Pennsylvania, 98%
of county and 80% of school district tax revenues come from
property taxes (Duvaleix and Kelsey 2000). Yet property
taxes are often blamed for forest management problems.
Writers such as Fairchild and Associates (1935), Duerr
(1960), Manning and Thompson (1969), Zivnuska (1969),
and Gregory (1972) have suggested that property taxes can be
biased against forestry because of the long time between
timber harvests. Klemperer (1974, 1976, 1977a, and 1977b)
has argued that the ad valorem property tax tends to depress
forestland values more than other land uses, such as agricul-
ture, potentially driving forestland into other land uses. As a
result of such concerns, nearly every state has modified its
property tax laws to provide special treatment of forests.
Nevertheless, there is little consensus on the ideal way to tax
timberland (Klemperer 1988).
Property taxation is generally based on the real estate’s
fair market value or “highest and best use.” Such a tax is
referred to as an unmodified ad valorem property tax. How-
ever, a variety of special forest taxes are used in the United
States, ranging from modified assessments based on produc-
tivity or current use values to yield taxes, rebates, and
exemptions (Klemperer 1988, Chang 1996). With a tax
