What does this "By some measure" mean?
gu124)In recent years, there's been a sharp decline in honeybee numbers. By some measure the wild population has nearly disappeared, and if honeybees were to become extinct, we would be in trouble...

(And there's just a typo, keannu: 'By some measures...'. 'By some <expression-of-distance>...' is possible (with a different meaning) in some cases, for example 'She beat him by some distance' - which means 'by quite a significant distance'. But with 'measure' the singular doesn't work.
