Wenhai Lake, a sub-alpine lake within the Lashihai Nature Reserve,
is another habitat for migrating birds, most notably the endangered black stork.
Each year, for reasons not yet completely known, Wenhai undergoes a transformation
from sub-alpine lake to grazing grasslands.
Beginning in early spring, the lake gradually disappears,
believed to drain through underground limestone formations to Lashi Lake,
about 500 meters below. Then, with the return of the summer rainy season,
Wenhai Lake begins to fill again. By fall it reaches its full size,
ready for the arrival of migratory birds in late December.
The watershed’s highland forests support a wide variation of plant and animal species,
including protected raptors, forest wildlife, traditional medicinal plants and treasured fungi.
In spring, the region’s famous rhododendrons – over 15 species -- burst into bloom,
creating mountains of colorful flowers.
Traditional Yi communities are found in the areas higher upland on Jade Dragon Snow Mountain.
For centuries, the Yi were known as a fierce, slave-owning society,
but in recent decades they have given up their slaves to live peacefully with
their Naxi neighbors. Living in more isolated areas,
the Yi generally do not have much contact with outsiders,
although they are very friendly and welcoming to guests.
