Giant pandas (Ailuropoda melanoleuca) are well-known for their diet, which consists almost exclusively of bamboo. Their reliance on bamboo, which makes up 99% of their diet, requires dedicated efforts to meet their nutritional needs. Bamboo is not a single species but encompasses over 1,000 species globally, each with unique characteristics and nutritional profiles. This necessitates a strategic approach to ensure that the dietary needs of pandas are adequately met.
At the San Diego Zoo and San Diego Zoo Safari Park, teams cultivate nearly a dozen species of bamboo specifically for the pandas. In addition, over 100 species of ornamental bamboo grow on-site, providing a diverse array of options for the pandas’ consumption. This diversity is essential because pandas eat different parts of the bamboo plant—leaves, shoots, or stems—depending on the species and season.
The dietary preferences and nutritional needs of giant pandas are intricate. Despite their carnivorous ancestry, pandas have evolved to thrive on a plant-based diet, deriving their energy primarily from bamboo. This adaptation is unique among mammals. Pandas consume between 26 to 84 pounds of bamboo daily to meet their energy requirements, depending on what’s available seasonally. Given that bamboo is a low-nutrient plant, pandas must eat large amounts to obtain sufficient nutrients.
Providing an adequate variety of bamboo species is essential. Each type offers distinct textures, flavors, and nutritional benefits, allowing pandas to select what they need based on their dietary requirements and personal preferences. Additionally, bamboo’s availability changes with the seasons, which further influences the pandas’ eating habits. For instance, in spring and summer, pandas prefer tender bamboo shoots, which are higher in nutrients. In contrast, mature bamboo leaves and stems are consumed more frequently during the fall and winter months.
To accommodate these needs, the San Diego Zoo and its Safari Park cultivate an extensive range of bamboo species. This operation is far more complex than traditional farming, as bamboo requires specific growing conditions. The plantation must mimic the pandas’ natural habitat to produce the highest-quality bamboo. This involves understanding the soil composition, weather patterns, and managing pests and diseases that may threaten the bamboo crops. For instance, species like Phyllostachys, Pseudosasa, and Bambusa are commonly grown due to their suitable nutritional profiles and growth characteristics.
Harvesting bamboo is an ongoing, labor-intensive process. The zoo’s horticulture team monitors the bamboo’s growth, harvests it at peak freshness, and delivers it to the pandas in precise quantities. Bamboo is cut in sections, with some sections offering more nutritional value than others. Fresh shoots, for example, are rich in protein and are eagerly consumed by the pandas during the growth season. Mature stems and leaves provide essential fiber and are available year-round.
The team also tracks the pandas’ consumption closely, recording what they eat and identifying trends in their preferences. This data is critical not only for daily care but also for long-term health planning. Detailed records help adjust the feeding routines and make informed decisions about which bamboo species to plant more of in the future.
Understanding the preferences of each panda is crucial. Just like humans, each panda has individual tastes and nutritional needs. Female pandas, for instance, might require different nutritional intake during pregnancy and lactation periods. By offering a diverse "bamboo buffet," the caretakers can meet each panda’s unique dietary requirements. This approach ensures that the pandas remain healthy and active, supporting their overall well-being and longevity.
The care for giant pandas at the San Diego Zoo and Safari Park extends beyond just feeding them bamboo. It involves protecting and conserving these animals, which are still vulnerable in the wild. Habitat loss, climate change, and poaching are significant threats to wild panda populations. The zoo’s efforts in catering to the pandas’ dietary needs are part of a broader conservation initiative aimed at preserving this iconic species.
Educational programs and public displays, such as the "Homegrown" story, provide valuable insights into the pandas’ care. These initiatives help raise awareness about the importance of conservation and the complex work behind the scenes to maintain healthy panda populations. Visitors can see first-hand the bamboo buffet and learn about the intricate details that go into panda care starting Thursday, August 8.
In summary, the San Diego Zoo and Safari Park exemplify world-class care in their extensive efforts to grow and provide diverse bamboo species for giant pandas. This commitment ensures that the pandas receive the necessary nutrition while fostering conservation awareness and supporting global efforts to protect this beloved species.

If there’s one thing you know about giant pandas, it’s probably that they eat bamboo 🎋
With over 1,000 species of bamboo in the world, it takes a dedicated team and a lot of data to fulfill the nutrition needs of giant pandas. With 99% of their diet being bamboo alone, this is no small task.
As part of our world-class care for giant pandas, our teams grow nearly a dozen different species of bamboo at the San Diego Zoo and San Diego Zoo Safari Park. We also grow over 100 additional species of ornamental bamboo that can be harvested for giant pandas.
Pandas eat different parts of the plants depending on their preference, the variety of the bamboo, and the season, so offering a curated selection is critical to their care. Learn more in the story “Homegrown” at the link in our bio 🔗
