Bioenergy is a renewable form of potential alternative to traditional fossil fuels that has
come to the forefront as a result of recent concerns over high price of fuels, national
security, and climate change. Nonindustrial private forest (NIPF) landowners form the
dominant forest ownership group in the southern United States. These forests often tend
to have large quantities of small diameter trees. Use of logging residues and non-
marketable small diameter trees for bioenergy production can create economic opportu-
nities for NIPF landowners. The results demonstrated that landowners’ willingness to
harvest woody biomass was influenced by their ownership objectives, size of the forest,
structure and composition of tree species, and demographic characteristics. The model
found that relatively younger landowners who owned large acres of forestland with pine
plantations or mix forests had the potential to become a preferable choice for contractors,
extension foresters and bioenergy industries as they were more likely to supply woody
biomass for bioenergy. Findings of this study will be useful to bioenergy industries,
extension foresters, nonindustrial private forest landowners and policy makers.

1. Introduction and carbon-neutral energy, contribution to nation’s energy
In the United States, bio-fuels generation from biomass has
taken center stage in recent years with rapidly depleting
domestic oil supply and increasing dependence on politically
unstable foreign oil suppliers [1]. Forest and agriculture are the
two largest potential sources of biomass in the United States
with capacities of producing 368 and 998 million tons of
biomass respectively [2]. The forest-based biomass can be
obtained from different woody residues that are produced
during timber harvesting and other silvicultural operations,
the fuelwood collected from forests, urban wood waste, the
residues from mill operations,[2] woody and perennial
herbaceous crops and agricultural residues [3].
Several environmental and socioeeconomic benefits such
as reduction of greenhouse gas emissions through renewable

supply, enhancement of forest health, and generation of
income and employment for rural communities [4e6] are
some of the reasons behind the recent interest in renewable
energy sources in the United States.
About 48% of the forestland in the United States and 71% in
the South are owned by nonindustrial private forest (NIPF) or
family forest landowners [7]. NIPF growing stocks, from soft-
woods and hardwoods in the year 2002, were 491,800 million
cubic feet and 364,357million cubic feet, respectively [7]. Since
NIPF owners control a large part of the nation’s forest
resources, their forest management decisions are critical for
the supply of timber and other forest products in the United
States [8].
Though most of the current bio-fuel production in the
United States involves agricultural inputs, continuous use of
d.

food for ethanol and biodiesel production may have an
adverse effect on sustainable food supply in the long run
[9,10]. Conversion of 30% of the current corn productions to
ethanol shows a competition between feed and bio-fuel,
which indicates that an ambitious goal of energy security
cannot be achieved without utilizing other types of biomass
such as woodymaterials [11]. Thus, use of woody biomass can
help meet the energy demands of the nation without
compromising food demands of both people and domestic
animals [11]. Annual availability of 36.2 million dry tonnes of
recoverable logging residues for electricity production and
CO2 displacement [5] further justify that woody biomass is
a viable option for sustainable production of alternative
source of energy in United States.
In the southern United States, acreage of pine plantation
has increased considerably in the past few years [12]. Now,
many of these plantations are near maturity with declining
pulpwood markets [1]. Given the limited markets for small
diameter wood, large quantities of unthinned small diameter
trees, and damaged timber from natural disaster and pest
outbreaks have increased the risk of wildfire hazards and
negatively impacted forest health [4,12]. On the other hand,
demand for southern stumpage has declined considerably in
the last decade [12]. In the South, bioenergy can be produced
from a variety of woody materials including those obtained
as a byproduct of silvicultural operations and do not have
other attractive economic use [1]. Therefore, bioenergy brings
more economic opportunities in comparison to conventional
timber harvesting as silvicultural byproducts become addi-
tional source of income in bioenergy markets [1]. Past studies
have shown that timber harvesting decisions of landowners
are mostly dependent upon market price, landowner type,
bequest motives, size of forest tract, parcelization, environ-
mental preferences, management objectives, and a number
of demographic and forest management characteristics etc
[13e16]. Given the environmental and socioeeconomic
benefits associated with wood-based energy, it is possible
that influence of these factors on landowners’ decisions to
harvest woody biomass for bioenergy may be different than
conventional timber harvesting decisions. Similarly, the
feedstock for bioenergy can be obtained from the forest
without necessarily conflicting with the wildlife management
or recreational objectives of the landowners. Therefore, these
studies cannot be generalized for understanding landowners’
willingness for supplying wood-based biomass for bioenergy
industry. This study aims to understand different biophysical
and forest management characteristics like size of forest
parcels, length of ownership, size, structure and composition
of tree species, forest management objectives, mode of
harvest and demographic characteristics (like age, education,
income) which may be instrumental in predicting land-
owners’ willingness to supply woody biomass for bioenergy
production.
2. Landowner decision on timber harvesting
Willingness of forest landowners to harvest or supply wood
fiber from their land has been the focus of a number of
studies. Stordal et al. applied two step sample selection
estimation procedure to analyze the factors affecting land-
owner decisions and level of harvesting [17]. The result
showed that the interest in harvesting and harvesting levels
was influenced by factors such as forest management plan,
size and location of property, education and income from
agriculture [17]. Similarly, Favada analyzed empirical timber
supply models from Finnish nonindustrial private forests in
which age of landowner was found to be the important
factor in timber stocking decisions [18]. Likewise, Vokoun
et al. applied multiple bounded discrete choice (MBDC)
approach in which landowners were offered a range of
possible prices and multiple response options that allowed
them to express a level of certainty with their choices [19].
The authors identified size of forest ownership, length of
ownership, presence of existing structures and residence of
landowners as major determinants for their intensity
of harvesting [19]. Similarly, other studies have shown that
timber harvesting decisions of landowners are mostly
dependent upon market price, landowner type, bequest
motives, size of tract, parcelization, environmental prefer-
ences, management objectives, and demographic and forest
management characteristics [13e16,20,21]. But, none of
these studies have focused on understanding landowners
harvesting decisions to supply woody biomass for an
emerging market such as bioenergy.
There have been studies to understand NIPF landowner
attitude toward bioenergy. Munsell and Germain studied
some of the challenges and potential benefits associated with
woody biomass energy with an examination of current har-
vesting practices of private forest landowners [22]. The
authors highlighted that woody biomass, if harvested wisely,
can be used for bioenergy production without negatively
influencing the other forest management goals such as
sustainable harvesting of sawtimber, keeping considerable
amount of residual stock, and avoiding premature harvesting
[22]. Similarly, Foster et al. found logging residues, timber
from silvicultural operations like thinning and stand damaged
by natural disturbances as some of the easily available woody
biomass residueswhich had little or nomarket value [1]. Thus,
an emerging bioenergy market could be an alternative
opportunity for selling woody residues and small diameter
trees [1]. In short, these studies focus primarily on the
potential benefits of bioenergy for NIPF landowners. Though
earlier studies covered some general aspects of opportunities
associatedwith bioenergy, this study explicitly explores forest
management and biophysical forest characteristics that
potentially contribute to NIPF landowners’ participation in
biomass supply.
3. Methods
3.1. Data
The study area includes three southern states namely
Arkansas, Florida and Virginia. The list of nonindustrial
private forestland owners in Arkansas was obtained from the
Arkansas Forestry Commission and a commercial vendor.
Similarly, the lists of nonindustrial private forest landowners
of Florida and Virginia were obtained from the respective
b i om a s s an d b i o e n e r g y 3 5 ( 2 0 1 1 ) 1 8 6e1 9 2188
county tax assessor’s offices. Sixteen hundred landowners
from each state were randomly selected for the final survey.
Landowners that owned less than twenty acres of forestland
were removed from the database because theywere less likely
to engage in forest management activities [13,20]. The survey
instrument contained a variety of questions within four
sections related to general information about the respon-
dents, information about the land, forest management activ-
ities, and demographic characteristics. The survey was
conducted from September 2007 to August 2008, and generally
followed the recommendations of Dillman’s Tailored Design
Method [23]. The socio-demographic results from this survey
were consistent with previous studies conducted in similar
areas [24,25], which reduced some concerns for possibility of
non-response bias in sampling. Also, statistically insignificant
differences among early and late respondents based on two
sample t-test further reduced the possibility of non-response
error in this survey.
3.2. Statistical analysis
Since the dependent variable in the studywas binary, we used
binomial logistic regression for estimating the model param-
eters. The relationship between dependent and independent
variables was modeled using following equation [26,27].
EðY=xÞ ¼ pðxÞ ¼ eb0þb1
1þ eb0þb1
The likelihood function equals product of individual
contributions of each ith observation.
lðbÞ ¼Yni¼1
pðxiÞyi ½1� pðxiÞ�1�yi
Likelihood equations were used to estimate the value of
b that maximize the log likelihood with respect to each
parameter. (i.e. b0, b1, b2.. bj)
Xi¼1
�yi � pðxiÞ
� ¼ 0 for b0
Xi¼1
xi1
�yi � pðxiÞ
� ¼ 0 for b1
Xi¼1
xi2
�yi � pðxiÞ
� ¼ 0 for b2
and so on through the j different independent variables.
This provided values for estimating logit.
bgðxÞ ¼ b0 þ b1x1 þ b2x2 þ.þ bjxj
This was then be used to calculate an estimated value for
conditional probability.
bpðxÞ ¼ ebgðxÞ1þ ebgðxÞ
Unlike in ordinary least square model, coefficients of the
binary logistic model do not provide direct intuitive interpre-
tation [26,27]. Therefore, marginal effects of the independent
variables on the probability of occurrence of dependent vari-
able were estimated and reported accordingly.
3.3. Model and variable definitions
Previous studies have shown that different forest manage-
ment characteristics, such as: acreage of ownership, structure
and composition, forest management objectives, and demo-
graphic characteristics (age, education, income) affect land-
owner decisions [13,14,16]. Therefore, it can be assumed that
determinants of landowner decision to supplywoody biomass
for bioenergy industry will likely be a vector of forest char-
acteristics (size of forestland, species composition), demo-
graphic characteristics, and forest management objectives.
This can be expressed as,
WILLINGNESS ¼ fðBIOPH;FORMG;DEMO;MANAGEOBJÞwhere,
BIOPH is a vector of biophysical characteristics of the forest.
FORMG is a vector of forest management factors.
MANAGEOBJ is the landowner’s forest management
objectives.
DEMO is a vector of demographic characteristics of the
landowners.
Assuming rational behavior, landowners will maximize
utility from forestland by exercising their subjective prefer-
ence for either supplying woody biomass to bioenergy
industry or doing something else, given resource and budget
constraint. Hence, this situation can be explained with
random utility theory, which permits discrete choices within
a utility maximizing framework [28]. Given these conditions,
landowner’s indirect utility function can be expressed as Vi
(xi, q), where xi is a vector of measureable forest character-
istics, demographic characters and forest management
objectives and q denotes the choice of landowners to supply
woody biomass for bioenergy such that q ¼ 0 if landowner is
not willing to supply and q ¼ 1 if landowner is willing to
supply [28]. According to the Utility maximization concept,
a landowner is not willing to supply woody biomass for bio-
energy if that will not increase his indirect utility, Si (yi,
0) > Si (yi, 1) [28]. Similarly, a landowner will be willing to
supply woody biomass for bioenergy, if in doing so, yields
higher utility, Si (yi, 1) > Si (yi, 0) [28].
Random utility concept is based upon the relationship
between observed data and the utility maximization model
[29] with an assumption that the decision maker has
a perfect discrimination capability [30,31]. While landowners
are assumed to know their willingness to supply woody
biomass for bioenergy, these values can be revealed through
observed choices [30,31]. Therefore, this situation having
incomplete information about landowners’ willingness
reflects uncertainty in the model [30,31]. Earlier studies have
identified different sources of uncertainties such as unob-
servable individual attributes, observable withmeasurement
errors, and proxy measurements pertaining to such a situa-
tion [29e31]. Therefore, utility is modeled as a random vari-
able in order to reflect this uncertainty. More specifically, the
utility associated with landowners’ willingness or unwill-
ingness is given by

and 3ij is the stochastic part, capturing the uncertainty. This
model can be estimated using a binary logistic procedure, if
the error terms are assumed to be independent and identically
distributed [32,33]. Hence, the empirical model in this study
can be specified as:
WILLING ¼ f (LACRE, PLANTEDPINE, MIXFOREST, HARD,
TIMBERPROD, WILD, PRICETIMB, INCOME, AGE, EDUCATION,
SMALLD, KNOWB, FHEALTH, RESIDENCE)
The dependent variable (WILLING) was measured by the
observable choice of whether landowners will supply their
woody biomass for bioenergy. It was assumed that the woody
materials used in the bioenergy industry would likely to be in
the form of younger trees, deformed or salvaged trees, and
logging residues. Given that market for feedstock used in
wood-basedbioenergywasstill incipient, existingmarketprice
of the pulpwood in the respective states was used to under-
stand themarket entry decisions of landowners. The response
for this variable was binary, taking the value of “1” if the
landowner indicated positivewillingness (definitelywill sell or
probably will sell) to supply woody biomass at the bid price
offered or “0” otherwise. The independent variables included:
total number of acres owned by landowner (LACRE, expressed
as a logarithm), percentage of their land occupied by planted
pine (PLANTEDPINE), percentage of their land occupied by
mixed forest (MIXFOREST), timber production objective (TIM-
BERPROD), wildlifemanagement objective (WILD), importance
of timber price in harvesting decision (PRICETIMB), age of
landowner (AGE), and education of landowner (EDUCATION).
Other variables tested but not selected for final logisticmodels
were: landowners having small diameter tree (SMALLD),
percentage of their land occupied by Hardwood (HARD),
knowledge about bioenergy (KNOWB), forest health
(FHEALTH), and residence (RESIDENCE). Table 1 reports the
definition and descriptive statistics of the variables that were
finally selected in the logistic regression model.
The explanatory variables LACRE, PLANTEDPINE, and
MIXFOREST were continuous. It was hypothesized that land-
owners owning large amounts of land were more likely to
supply woody biomass for bioenergy since these landowners
were more likely to actively manage their forestland for
financial returns to their investment [34]. Therefore, the
variable LACRE was expected to be positive. Similarly, the
variable PLANTEDPINE was expected to be positive due to
the likelihood that the landowners who planted pine would
have timber harvesting motives due to their substantial
investment in pine plantation and silvicultural operations.
The landowners having mixed forests would have large
amount of understory residues, which could be used aswoody
biomass. Therefore, the variable MIXFOREST was also expec-
ted to be positive.
The management objectives of the landowners have
previously been identified as important factors in land-
owners harvesting decisions [14]. The variable TIMBERPROD
was a likert scale variable that was coded as 1 if the land-
owner indicated that timber production as a management
objective was very important or somewhat important, or 0 if
the landowner indicated that timber production as
a management objective was neutral, somewhat unimpor-
tant or not at all important. It was difficult to predict the
sign of the variable TIMBERPROD as some studies have
shown that timber management behavior of nonindustrial
private landowners is far less predictable than forest
product industries due to multi-objective nature of their
ownership [13,15,35]. Therefore, the sign for this variable
must be found empirically. Similar to TIMBERPROD, the
variable WILD was coded as 1 for landowner who indicated
wildlife management objective was very important or
important, or 0 otherwise. Generally, the landowners having
wildlife management objectives tend to value amenities
higher than timber [24]. On the other hand, majority of such
landowners tend to be sensitive toward environmental
issues [36,37]. Given the environmental and socioeeconomic
benefits of bioenergy, the sign of this variable was difficult
to predict in this model. Likewise, the variable PRICETIMB
was coded as 1 for those landowners who indicated timber
price was very important or somewhat important in their
harvesting decision, or 0 otherwise. The sign of the variable
PRICETIMB was also difficult to predict due to multi-
b i om a s s an d b i o e n e r g y 3 5 ( 2 0 1 1 ) 1 8 6e1 9 2190
objective nature of nonindustrial private forest landowners
[13,15,35]. The variable AGE was coded as 1 for those land-
owners who were older than 60 years and 0 for others.
Earlier research have indicated that older landowners were
less interested in any kind of active management activities
[38]. Therefore, AGE was expected to be negative as majority
of the older landowners are likely to enjoy recreational
benefits of forest than harvesting woody biomass from their
forestland. Similarly, the variable EDUCATION was coded as
1 for those landowners who had at least Bachelor’s degree
or equivalent as their highest level of education, 0 other-
wise. The variable EDUCATION was expected to have
a positive coefficient because advanced education would
make people more aware about environmental issues.
Therefore, they were expected to be more likely to supply
their woody biomass for wood-based energy.

4. Results and discussion
4.1. Descriptive statistics
Among three age groups (<45, 45e65, >65), the largest
percentage of respondents (About 57% of the landowners in
Arkansas, 61% in Florida and 50% in Virginia) belonged to
the group of 45e65 years. Similarly, 26% of respondents in
Arkansas, 20% in Florida and 31% in Virginia were above 65
years of age, whereas the smallest percentage of respon-
dents in each state (17% in Arkansas, 19% in Florida and 18%
in Virginia) were less than 45 years old. Among three cate-
gories of education levels (did not complete high school,
high school or equivalent vocational/technical training, and
bachelors’ degree or higher), 50% of respondents in Arkan-
sas, 42% in Florida and 43% in Virginia had a high school or
equivalent degree. Similarly, 45% of the respondents in
Arkansas, 54% in Florida and 54% in Virginia had at least
a bachelor’s degree. On the other hand, 5% of the respon-
dents in Arkansas, 4% in Florida and 3% in Virginia did not
complete high school. We also had three categories of
income levels (less than 25K, between 25Ke75K, >75K), 12%
of respondents in Arkansas, 10% in Florida and 6% in Vir-
ginia had an annual income less than 25 thousand dollars
per year. Similarly, 47% of respondents in Arkansas, 34% in
Florida and 40% in Virginia had an annual income in the
range of 25e75 thousand dollars per year. Likewise, 41% of
respondents in Arkansas, 55% in Florida and 55% in Virginia
had an annual income higher than 75 thousand dollars per
year.
About half of the landowners in each state were retirees.
The results also revealed that 78% of the landowners in
Arkansas, 83% in Virginia and 86% in Florida believed energy
dependence on fossil fuels to be crucial for national security
as well as healthy economy. However, 58% in Arkansas, 57%
in Virginia and 43% of the landowners in Florida were not
aware of energy generation from cellulosic biomass. This
shows that while most of the landowners in three states
realized the need of alternative sources of energy, a consid-
erable number were not aware of using woody biomass for
bioenergy.
4.2. Results from logistic regression analysis
Estimates for the willingness to supply woody biomass model
are presented in Table 2. The overall model was significant as
the chi-squared test on the log-likelihood ratio was significant
at 99% confidence level. None of the independent variables
were highly correlated with each other, which reduced the
concern of multicollinearity in our model. As expected, the
significant (alpha ¼ 0.05) and positive coefficient on the loga-
rithm of total area owned (LACRE) showed that landowners
were more likely to supply woody biomass for bioenergy as
the size of their ownership increased. Consistent with the
findings of Beach et al, this result indicated that the land-
owners owning larger forest acres would have economies of
scale in biomass harvesting [39]. In term of marginal effect,
(calculated at themean, LACRE¼ 2.05) a unit increase in log of
acreage owned was associated with 13.71% increase in the
likelihood that the landowner will supply woody biomass for
bioenergy. Similarly, species composition of the landowners’
forest influenced their decision to supply woody biomass for
bioenergy. Landowners who owned pine plantations and
mixed forests were more likely to supply woody biomass.
The variable TIMBERPROD was negative and significant at
99%. This indicated that the landowners who valued timber
production (growing and selling timber) as an important
management objective were less likely to supply woody
biomass for bioenergy. Similarly, the variable PRICETIMB was
also negative but not significant. Negative sign of the variable
TIMBERPRODmay be an indication of the profit maximization
motive of the landowners with strong timber management
b i om a s s a n d b i o e n e r g y 3 5 ( 2 0 1 1 ) 1 8 6e1 9 2 191
objectives. The forest biomass that can be used in the
production of wood-based energy would probably be obtained
from young trees, species not in high demand, deformed or
diseased trees, salvaged trees or logging residues. Therefore, it
is probably unlikely that biomass for bioenergy will compete
with traditional lumber industries (and other secondary
producers that use lumber as input), unless the price of
biomass is high enough. Nonetheless, their negative prefer-
ences indicated some degree of skepticism among NIPF
landowners about the feedstock used in wood-based bio-
energy industry. Given that considerable numbers of land-
owners in all the states were either uncertain or not familiar
about wood-based bioenergy, they might believe that their
interest in supplying timber to lumber industry may conflict
with the concept of producing alternative energy from cellu-
losic biomass.
On the other hand, the variable WILD was positively
significant, albeit marginally, at 90%, which meant that
landowners having wildlife management objectives were
more likely to supply their woody biomass for energy.
Generally, the landowners having wildlife management
objectives do not like to clear-cut their timber for commercial
sales. However, woody materials used in wood-based bio-
energy can also be obtained from partial-cutting methods,
which do not necessarily conflict with wildlife management
objectives of the landowners and may even aid in habitat
enhancement. Given that small diameter trees and logging
residues (small branch, thinning, tops of trees and other stem
wood fromharvested trees) are commonly used as a feedstock
in bioenergy industries, it is likely that NIPF landownermay be
interested in maintaining forest health by harvesting such
wood products with a minimal disturbance on existing
species diversity. Among demographic variables, AGE was
negatively significant at 99%, which indicated that environ-
mental benefits of bioenergy did not appeal to older land-
owners. This was consistent with findings of earlier studies on
cost share, harvesting and reforestation behavior of land-
owners [17,33]. Similarly, the variable EDUCATION was
positive and significant at 90%. This was consistent with the
hypothesis that higher level of education would directly
influence the perception of landowners toward environ-
mental and energy security issues.
Table 3 gives the predicted and actual outcomes for the
model which measures the performance of the model in
predicting a landowner’s willingness to supply woody
biomass. The model correctly predicted 86.8% of the obser-
vations (Table 3). It is noteworthy that such a large majority of
the landowners were willing to supply woody biomass, if they
were offered with bids equivalent to existing pulpwood price.

Actual Predicted Total % Correct
0 1
0 65 7 72 86.8
1 8 472 480
Total 552
These results are not surprising as landowners had little to
lose if they supplied woody materials in a price equivalent to
the existing pulpwood prices. Moreover, several
socioeeconomic and environmental benefits might have
attracted landowners to be willing to supply woody biomass
for energy. This study, however, refrained from covering the
issue of economic viability of wood-based bioenergy. There-
fore, cost-effectiveness of biomass used inwood-based energy
would be an important topic for future research.
5. Conclusions
Sustainable development of bioenergy and bio-based
production system requires a reliable biomass supply at
a reasonable cost which to a large extent depends upon
landowner decisions on whether or not to supply woody
biomass. This study showed that the majority of the land-
owners in the study area regarded nation’s dependence on
imported fuel as critical for both national security and healthy
economy. Such opinions of the landowners reflect their
concern about energy security. However, significant number
of landowners were either uncertain or not familiar about the
concept of producing alternative energy from cellulosic
biomass. Similarly, low motivation of older landowners
toward wood-based energy suggests that they would first
need to be educated and informed about this emerging
market.
This willingness to supply model showed that landowners
having wildlife management objectives were likely to supply
woody biomass. This result may have long term implications
for the future of bioenergy in United States as wildlife and/or
aesthetics are the prime management objectives for the
majority of the landowners [25,36,37]. Similarly, our study
suggests that young landowners owning large pine planta-
tions or mix forests could become preferable choice for the
contractors, extension foresters and bioenergy industries as
they are more likely to supply woody biomass for bioenergy.
Given general landowner skepticism regarding biomass
supply for energy, there is need for a full range of communi-
cation in the form of education and outreach programs. It is
also important to note that excessive and unsustainable har-
vesting of woody biomass could result in loss of biodiversity,
nutrient leaching, soil erosion, infiltration reduction and
increase in sedimentation. Therefore, outreach programs
about current market price of woody biomass, significance of
environmental benefits, best management practices,
employment and other opportunities related to bioenergy can
motivate landowners toward supplying biomass for energy
production.
