The road behind the predator exhibition area was originally sealed off; nobody knew what was being built there, but it has now opened up.
Liu Wei and his friends walked along the road for a while and discovered that it led to an open lake with large areas of reed marshes near the shore. Without the usual pavilions or waterside gazebos common in most parks' waterfowl lakes, this place looked far more natural.
Many zoos' former waterfowl lakes were designed in the style of traditional gardens, with no consideration for the animals' environmental needs.
The most typical issue was the vertical retaining walls at the lakeside, creating barriers between land and water for the animals, with no suitable habitat around the waterfowl lake.
At Linhai Zoo, however, the retaining walls were sloped to facilitate the waterfowl's access to and from the water.
Scattered at the water's edge and on the lake's surface were some fallen logs and tree roots.
