The beautiful hillside of Landour Mussoorie is surrounded by lush forests and Oak trees. These trees are a vital part of the ecosystem, providing shade, shelter, and food for a variety of wildlife. However, the Oak trees in Landour, Mussoorie are now facing a serious threat from massive Oak seed infestation. During nature walk, I observed that the acorns are heavily infested by some kind of insect. The rate of infestion is alarming as compared to previous years.This infestation is caused by a tiny insect that lays its eggs inside the acorns of Oak trees. After the egg hatches the larva feeds on the acorns and finally emerges out of the acorns. The natural regeneration of Oak tree is already an issue as there are already many factors which cause poor seed viability. But the present situation of high rate of pest infestation might pose a serious threat to the future population of Oak trees. In this post, we’ll explore the impact of the Oak seed infestation on Landour Mussoorie’s Oak tree population and discuss what can be done to protect these miraculous trees.
