addition, some species of animals are lost completely
in such inferno while others may not be able to exist
within the ecosystem. Thus, there is loss of
biodiversity.

Strategies for conservation
The need for forest and wildlife conservation for
genetic preservation, quantity and acceptable quality
to meet the domestic, industrial, resources population
manipulation and recreational requirement require
adequate concentration. In order to ensure sustainable
utilization of forest and wildlife resources, there is need
to ensure control of wildfire in all ecosystems through
enforcement of adequate legislation and establishment
of monitoring stations in areas prone to wildfire.
It is important to establish well-equipped and
adequately staffed fire stations in strategic locations
that will ensure prompt attention to fire outbreaks. To
ensure that even if there arises any situation of
unplanned fire outbreaks, they can be quickly and
adequately controlled by these stations. The role of a
well-coordinated anti-indiscriminate fire campaign
