The Connecticut Agricultural Experiment Station has reported significant differences in acorn production across Connecticut for 2025. Researchers observed 575 red and white oak trees at twelve locations throughout the state to compile their findings.
According to the study, red oak trees in the northwestern part of Connecticut are producing a bumper crop of acorns this fall. The northeastern areas are also seeing a good acorn yield. In contrast, central and southern regions are experiencing widespread crop failure, which follows last year’s strong acorn production in those areas. Joseph Barsky, lead forest researcher for the study, said, “Hikers may find some trails in Litchfield County this fall to be completely covered in acorns.”
White oak trees have continued to show poor acorn production statewide, continuing a pattern seen over the past decade. Barsky noted, “Prolonged periods without adequate white oak acorn production are leading to fewer seedlings becoming established in our forested areas.” He added, “Over time, this shift will lead to a reduced component of white oak in our future forest and negatively impact the existing ecological processes and associated industries that depend on white oak.” White oaks were once common but have declined due to repeated insect defoliation and drought.
The Oak Mast Surveillance Program includes participation from other states such as New Jersey, Pennsylvania, and Virginia. These states completed their annual assessments for 2025 and reported average red oak crops. Virginia had a good white oak crop; all other states reported fair to poor results for white oaks.
