These basic numbers are collected once a month during the acorn ripening season (October to January). The research team has laid out eight "transects" (essentially fixed paths in the woods) at different altitudes and terrain for routine surveys (each transect being 200 to 1000 meters long), and data is collected on these in a regular sequence.
這 4 種基礎資料在青剛櫟結果季（每年 10 月到隔年 1 月）時每個月收集一次，研究團隊並依據不同海拔和地形，設了 8 條例行調查的穿越線（每條 200 ~ 1,000 公尺不等），逐一收集備存。
