Small-scale private forestry is widespread in many countries and occupies 40.3% of the total forest area in Lithuania. The pursuit of sustainability has become one of the main goals of forest policy. In order for small-scale private forestry to be based upon sustainability principles, its sustainability must first be assessed and analyzed. This study assesses the sustainability of 385 small forest holdings of Lithuania using established forest sustainability assessment methods and performs an analysis of the factors influencing the sustainability of small forest holdings using correlation analysis. The Lithuanian small-scale forest holdings were categorized in terms of their level of sustainability as being very high and high (assessed on a five-point scale as 3.5–5 points)—13.6%, middle (2.5–3.5 points)—28.8%, or low and very low (1.0–2.5 points)—57.6%, with the corresponding proportion of holdings indicated as a percentage. A total of 40 independent variables were hypothesized, and their correlation with the sustainability assessments of the holdings was verified. The correlation analysis found mostly weak but reliable (p
< 0.05) relationships with 23 independent variables: very weak—12 variables, weak—7 variables, middle—2 variables, and strong—2 variables. Moderate and strong correlations were found for the following variables: the owner’s view of the forest’s economic importance (correlation coefficient: 0.862), income per hectare (0.840), the importance of forestry in the common activity of the owners (0.525), the percentage of mature stands (0.476), the diversity of activities in forest holdings (0.361), and how the wood is used (0.328).
