* Data limitations: Historically, accurate and consistent population data for pandas wasn't readily available. Estimates are often based on surveys and expert assessments, which can vary in methodology and reliability.
* Fluctuations: Panda populations have historically fluctuated due to factors like habitat loss, poaching, and bamboo flowering cycles.
* Conservation efforts: Significant conservation efforts in recent decades have helped increase panda numbers.
However, it's generally agreed that the panda bear population reached a critically low point in the 1980s, with estimates suggesting as few as 1,000 individuals remaining in the wild.
Important note: While panda numbers have increased since then, they are still considered vulnerable according to the IUCN Red List. Continued conservation efforts are essential to ensure their long-term survival.
