Fall 2023
At Hastings Natural History Reservation, students studied the trade-offs between annual tree growth and acorn germination potential in valley oaks. They collected 585 acorns and both measured and assessed them for insect damage and rot. The study found that as average annual tree growth increased, average acorn weight decreased. No relationship between annual tree growth and insect deterrence and rot was detected. Image credit: Valeria Katona
