How to Trace Any Giant Panda’s Family Tree: The Studbook Genealogy Guide

Key Fact: Every captive giant panda ever born — over 1,500 individuals across nearly 60 years — is recorded in the International Studbook with a permanent unique number. That number is the key to an unbroken chain of parent-child relationships stretching from any panda alive today back to the wild founders of the captive population. Using the PandaCommon database, you can trace any panda’s lineage in minutes: start with a name or studbook number, follow the fatherStudbook and motherStudbook fields, and build a family tree that reveals the hidden genetic connections linking pandas from Chengdu to Washington to Tokyo.

Key Takeaways

1. The studbook is a complete genealogy of the captive panda population — every individual links to its parents through unique studbook numbers, creating a single family tree covering all 1,500+ captive pandas.

2. You can trace any panda’s lineage in three clicks on PandaCommon — from studbook number to parent profile to grandparent profile, following an unbroken chain back to the wild founders.

3. The family tree has practical meaning — it reveals inbreeding risk, identifies genetically valuable individuals, and explains why some pandas are prioritized for breeding while others are not.

What Is a Panda Family Tree?

I have spent years working with the panda studbook database, and the question I hear most often is deceptively simple: “How is this panda related to that panda?”

The answer is contained in a single number.

The International Giant Panda Studbook assigns every captive panda a permanent unique identifier at birth — a studbook number. That number connects directly to two other studbook numbers: the father’s and the mother’s. Those numbers connect to four more: the four grandparents. The four connect to eight great-grandparents. In seven generations, a single panda’s family tree includes 254 direct ancestors — each identified by a studbook number, each with its own profile, each connected to the next.

This is not a metaphor. It is a database structure that actually exists, and it is the foundation of every genetic management decision made in the global panda breeding program.

What a Studbook Number Contains

When you look up a panda’s studbook number on PandaCommon, you are accessing a data record that includes far more than a name and a photo. The complete record for any panda includes:

• Studbook number — The permanent identifier. Numbers are assigned sequentially: Pan Pan received #001, and the count continues today with numbers in the 1400s.
• Sire and dam studbook numbers — The father and mother, each identified by their own studbook numbers. If either parent is unknown (a wild-caught founder, for example), the field shows 0.
• Birth data — Date, location, litter size. Twin births are flagged because they are common — approximately 45% of captive births are twins.
• Sex — Critical for breeding recommendations.
• Location history — Every facility the panda has lived at, with arrival and departure dates.
• Offspring list — Every cub or set of cubs, identified by studbook number.
• Breeding history — Reported mating attempts and outcomes.
• Status — Alive or deceased, with date of death if applicable.

The studbook number alone does not encode this information — it is simply a pointer to the database record. But once you know the number, you can access the entire family history.

Tracing a Lineage on PandaCommon

The PandaCommon panda profile page is designed for genealogical exploration. Here is the method I use when I want to trace a lineage:

1. Find the starting panda. Search by name or studbook number. Every profile page displays the fatherStudbook and motherStudbook fields in the identity section.

2. Follow a parent. Click on either studbook number. This takes you to the parent’s profile, where you will find its own fatherStudbook and motherStudbook fields.

3. Repeat. Continue clicking upward through the generations. After four or five clicks, you will reach a wild-caught founder whose parent fields show 0 — the end of that branch.

4. To trace forward (offspring), scroll to the Family section of any panda’s profile. Offspring are listed with their studbook numbers. Clicking any offspring number opens its profile.

This process works for any panda in the database. The chain is always complete for captive-born pandas. Every captive panda has two parents recorded (or marked as unknown for founders), and every parent has its own profile.

Case Study: Fu Bao to Pan Pan

Fu Bao (#1084) is the most famous panda in South Korean history — born July 20, 2020, at Everland Resort to parents Ai Bao and Le Bao. Her birth transformed Korean panda tourism and sparked a wave of panda fascination documented in our article on the Fu Bao phenomenon.

Here is her lineage traced upward through the studbook:

Generation	Panda	Studbook	Relationship to Fu Bao
0	Fu Bao	#1084	Self
1	Ai Bao (mother)	#840	Mother
1	Le Bao (father)	#839	Father
2	Hua Ni (maternal grandmother)	#528	Mother’s mother
2	Yuan Yuan (maternal grandfather)	#455	Mother’s father
2	Xin Xin (paternal grandmother)	#582	Father’s mother
2	Lu Kou (paternal grandfather)	#576	Father’s father
3	Lei Lei (maternal great-grandmother)	#374	Mother’s mother’s mother
3	Pan Pan (maternal great-grandfather)	#001	Mother’s mother’s father
3	Yong Liang (maternal great-grandfather)	#108	Mother’s father’s father

The key connection: Hua Ni, Fu Bao’s maternal grandmother, is the daughter of Pan Pan (#001). This means Fu Bao carries Pan Pan’s genes through her maternal line — three generations separate her from the most influential panda sire in history.

In three steps, the studbook reveals that Fu Bao — a panda born in South Korea to parents from China — traces directly to Pan Pan, a wild-born panda captured in Sichuan in 1985. The studbook connects continents and generations in a single chain.

Why Pan Pan Appears Everywhere

Pan Pan (#001) was captured from the wild in Baoxing County, Sichuan, in 1985. He entered the captive population at a critical moment: the early captive breeding program had very few successful sires, and the population was at risk of a genetic bottleneck.

Pan Pan solved that problem. He sired over 130 descendants — more than 25% of the global captive population at his peak. His offspring include:

• Bai Xue (#561) — Mother of Tai Shan (#595), the first panda born at the Smithsonian National Zoo through artificial insemination
• Hua Ni (#528) — Grandmother of Fu Bao
• Tian Tian (#381) — Mother of Mei Xiang at the Smithsonian
• Numerous sons who themselves became prolific breeders

The Pan Pan lineage is the most thoroughly documented family line in the studbook. It is also the most carefully managed: because Pan Pan’s genes are so widely distributed, the studbook system now prioritizes breeding pandas that carry minimal Pan Pan ancestry, to prevent his genes from saturating the population. Our article on studbook genetic management covers this challenge in detail.

Understanding Maternal and Paternal Lines

The studbook tracks both sides of every panda’s family tree, and they often tell very different stories.

The maternal line reveals matriarchal dynasties. Lei Lei (#374), a wild-caught female with a damaged paw, raised five cubs — all of whom survived to adulthood at a time when cub mortality was high. Her daughter Long Xin became a mother of twins. Her daughter Zhu Yun was the mother of Tuan Tuan and Yuan Yuan — the pandas gifted to Taiwan in 2008. Lei Lei’s maternal line now extends through four generations.

The paternal line reveals the impact of individual sires. Pan Pan is the extreme case, but other males have also shaped the population. Lu Lu (#576), the father of Le Bao, has over 50 descendants. Zhuang Zhuang (#506) contributed to the genetic foundation of the CCRCGP population.

When you trace a panda’s lineage on PandaCommon, pay attention to both sides. A panda may have a famous father but an unknown mother. It may descend from Pan Pan on one side and from Lei Lei on the other. The studbook captures both contributions equally.

Panda Genealogy vs Dog Pedigrees

The panda studbook and a purebred dog pedigree serve similar purposes — tracking lineage to manage genetic health — but there are critical differences:

Feature	Panda Studbook	Dog Pedigree
Scope	All captive pandas globally	Single breed registry
Population size	~700 living individuals	Thousands to millions per breed
Founder diversity	High (wild-caught founders)	Low (closed studbook)
Inbreeding management	Scientifically optimized (PMx)	Variable by breed
Outcrossing possible	Yes (wild pandas)	No (closed studbook)
Breeding purpose	Genetic diversity maintenance	Trait standardization

The most important difference: the panda studbook is an open, continuously diversifying system. New wild pandas can enter the population (though this is now rare), and the explicit goal is to maintain diversity. Dog pedigrees, by contrast, are closed systems where the gene pool is fixed and inbreeding is a persistent problem — a challenge explored in the genetic consequences of the Pan Pan bottleneck.

What Most Visitors Miss: Hidden Metadata

After years of working with the studbook, I have found that casual users — and even some researchers — overlook three layers of data embedded in every panda’s record:

Transfer history reveals genetic logistics. When you see that a panda was born at the Wolong Hetaoping Base, moved to Bifengxia at age 2, then to the Chengdu Research Base at age 5, then to Everland Korea at age 8 — you are seeing the studbook’s transport layer. Every transfer was arranged in service of a breeding recommendation. The panda did not move for tourism. It moved because a genetics algorithm calculated that it should breed with a specific individual at the destination facility.

Twin status is genetically significant. Approximately 45% of captive panda births produce twins. In the wild, the mother typically abandons the weaker cub to focus on the stronger one. In captivity, keepers use the twin-swapping technique to raise both cubs. When a panda is a twin, it matters genetically: its sibling shares the same parents and carries the same genetic relationship to the rest of the population. The twin survival mechanism is one of the most carefully managed aspects of the breeding program.

Deceased relatives still influence the studbook. A panda that died in 1995 still appears in the ancestor chain of every descendant. Its studbook number is never retired, and its genetic contribution is still calculated into the population’s mean kinship. The dead are not removed from the studbook — they remain, accurately, as nodes in the family tree.

Frequently Asked Questions

How are studbook numbers assigned?

Sequentially at birth. The first panda entered in the modern studbook was Pan Pan (#001) in 1985. Every birth since has received the next available number. As of 2026, numbers have reached the mid-1400s. Number assignment is centralized through the Chinese Association of Zoological Gardens.

Can I trace the family tree of a wild panda?

No. Wild pandas are not in the studbook. Their relationships are studied through fecal DNA analysis, which can identify parent-offspring pairs within a specific population but does not produce the complete multi-generational lineage that the studbook provides for captive pandas.

Why do some pandas appear to have an unknown father or mother?

Wild-caught founders — pandas brought into captivity from the wild — have unknown parents by definition. Their fatherStudbook and motherStudbook fields show 0. All captive-born pandas since then have complete parentage records.

How do I find a panda’s studbook number if I only know its name?

Use the PandaCommon search function. Search by either the English name or the Chinese name. If the panda has a studbook number, it will be displayed at the top of its profile. If multiple pandas share a name, the studbook number distinguishes them.

What is the deepest lineage in the database?

The deepest accessible lineages go back approximately 7-9 generations. A panda born in 2025, for example, might trace to a wild-caught founder captured in the 1960s through a chain of 7-8 intermediate ancestors. Beyond about 10 generations, the record-keeping becomes fragmentary — the modern studbook system only became standardized in the mid-1980s.

Build Your Own Trace

The PandaCommon database is built for exploration. Pick any panda — start with one you know, like Fu Bao, or one you have never heard of — and trace its lineage. Follow the mother line and the father line separately. See how far you can go before hitting a founder. The studbook number that starts your journey is the key to a family tree that spans continents, decades, and generations — a tree that is still growing every time a new cub is born.
