Acorn mast data (1995-2023), Black Rock Forest, Cornwall, NY

Acorn abundance has been tracked annually since 1995 at Black Rock Forest (BRF), Cornwall, NY between September and October to coincide with peak acorn drop. From 1995 to 2010 all acorns were counted within a circular plot thrown 10 times at 15 to 20 locations throughout BRF. Beginning in 2004 individual oak trees were visited and DBH and number of acorns under the drip line of the tree were counted at the same 15 to 20 locations within BRF.

自1995年起，研究人员于每年9月至10月（正值纽约州康沃尔黑石森林（Black Rock Forest, BRF）的橡子脱落盛期）对橡子丰度开展年度追踪监测。1995年至2010年期间，研究人员在该森林内的15至20个采样点处，各布设10个圆形样地，对样地内的全部橡子进行计数。自2004年起，研究人员在上述15至20个采样点处对单株橡树进行实地走访，统计该树树冠滴水线范围内的胸径（DBH）与橡子数量。
