Explanations: answer key for all 10 questions

Q1: Which species includes the oldest known individual trees?
Answer: Great Basin bristlecone pine
Its scientific name is Pinus longaeva.
Q2: Roughly how old is the tree called Methuselah?
Answer: Over 4,800 years
It sprouted around 2800 BCE.
Q3: In which mountains does Methuselah grow?
Answer: The White Mountains of California
It is in the Inyo National Forest.
Q4: Why is Methuselah's exact location kept secret?
Answer: To protect it from vandalism
Visitors walk among its neighbors.
Q5: Why do bristlecones live so long?
Answer: Slow growth in harsh conditions creates dense, resinous wood
Few pests or rot affect them.
Q6: What is strip-bark growth?
Answer: Only a narrow strip of living bark keeps part of the tree alive
Parts of the tree can die back.
Q7: How long can bristlecone needles stay on the tree?
Answer: Decades
Some last about 40 years.
Q8: What is the study of tree rings called?
Answer: Dendrochronology
Bristlecones provide very long records.
Q9: How have bristlecone rings helped science?
Answer: By calibrating radiocarbon dating
Rings give precise calendar years.
Q10: What happened to the Prometheus bristlecone in 1964?
Answer: It was cut down during research
It was later found to be about 4,900 years old.

Bristlecone Pine Quiz – Methuselah and Earth's Oldest Trees

Great Basin bristlecone pines, Pinus longaeva, grow on harsh mountain slopes in California, Nevada and Utah. A tree called Methuselah in California's White Mountains is over 4,800 years old, and its exact location is kept secret to protect it.

Bristlecones grow very slowly in cold, dry conditions, producing dense, resinous wood that resists rot and insects. Many show strip-bark growth, where only a narrow strip of living bark sustains part of the tree, and their needles can last decades.

Tree-ring studies of bristlecones have created records thousands of years long, helping scientists calibrate radiocarbon dating. In 1964 a tree later called Prometheus was cut down during research in Nevada and found to be about 4,900 years old.
