1980-89 年的 10 年间，阿盖尔有 15 对金雕成功繁殖（羽翼丰满的幼雏/对）。对 15 对鹰的潜在狩猎范围内幼小的人工林数量进行了测量。 1980 年每个范围的林业数量与 1980-89 年期间的平均育种成功率之间没有显着关系。然而，截至 1970 年，育种成功与林业种植量之间存在显着的负相关关系，因此育种研究开始时至少有 10 年历史。由于金雕潜在狩猎范围的造林而导致的繁殖性能受到抑制，只有在相当长的滞后期之后才能被检测到。
Breeding success (fledged young/pair) was recorded for 15 pairs of Golden Eagles in Argyll over 10 years 1980–89. The amount of young plantation forestry in the potential hunting ranges of the 15 pairs of eagles was measured. There was no significant relationship between the amount of forestry in each range in 1980 and mean breeding success over the period 1980–89. However there was a significant negative relationship between breeding success and the amount of forestry planted up to 1970 and therefore at least 10 years old at the start of the breeding study. Suppressed breeding performance consequent upon afforestation of the potential hunting range of Golden Eagles may be detectable only after a considerable lag period.
