Removal
of dead and fallen trees

Dead
tress are very crucial for several animals including this
hole nesting Black Woodpecker |

With prohibition of green tree felling in national
parks and wildlife sanctuaries, another emerging threat that constantly
surfaces is the attempts to harvest dead and fallen trees by Forest
departments. This, despite the fact that the removal of dead and
fallen trees is prohibited by law. Such prescriptions usually
result in order to generate revenue for the government which in
any case, is under constant pressure from the timber lobby.
Dead and fallen trees have great ecological
value. Numerous species of invertebrates depend upon the dead
and fallen for both food and shelter. These dead trees are the
major source of food for all the insectivorous birds and mammals.
They shelter hole-nesting birds like woodpeckers, hornbills, owls,
barbets, parakeets, mynas, and so on. In Nagarahole National Park
alone 34 species that amounts to 15% of the bird species in the
whole of the national park are hole nesting. If dead and fallen
trees are removed, these species that are admirable pest controllers
will greatly suffer and there will be a disastrous affect on the
ecological equilibrium. Extinction of bird species will also have
a catastrophic effect on the plant community as they will loose
their seed dispersers. The removal of dead trees affects integrity
of old growth forests.
Further, many species of mammals like pangolins,
bears, and mongoose also depend upon these dead and fallen for
their supply of food and nutrients. Scores of both small and large
mammals use the cavities of dead trees to safeguard their young
ones.
There often is a misconception that dead
and fallen trees are a threat to the forests during the fire season.
This perception is completely incorrect and what is vital is good
fire protection. In fact the decomposers in the forests like mushrooms
depend upon the dead plant produce to enrich the forest soil with
nutrients.
