Monarch clusters on Monterey cypress in Santa Cruz. While monarchs are congregated in one place, scientists estimate their population numbers. Can you guess how many monarchs are pictured here? Our biologists estimate 11,000 monarchs are clustered in this tree. This number might sound promising but overall, numbers are declining.
