Avian species provide pest control services in some agricultural systems, which may incentivize farmers to conserve natural habitats for native biodiversity. A critical component of this equation, however, is verifying that avian species are consuming potential pest species in the agricultural ecosystems. We used a DNA metabarcoding approach to determine the frequency of pest presence in songbird fecal samples collected from birds caught on diversified, low-intensity farms in New England, USA, during the bird breeding season. Twelve species of insect pest were identified in fecal samples, and across all songbird species 12.6% of samples included DNA from at least …

Individuals and families collectively own more than 118 million ha of forestland in the USA. Using data from the USDA Forest Service’s National Woodland Owners Survey (NWOS), we characterize ecosystem services being produced on family forests as well as the beneficiaries who enjoy them. Approximately half of family forest owners provide one or more provisioning services. With the exception of logs, the provisioning services provided by the majority of owners are enjoyed directly by owners or their close associates (i.e., family, friends, and neighbors). Similarly, while more than half of family forest owners have provided recreational opportunities, a cultural service, …
