QUESTION 3: Landscape ecology and metapopulations
[35]
What is Landscape ecology? In a Namibian context, using a landscape as an ecological
management unit, choose one of the following natural resources and explore a) the
appropriate landscape scale of managing the resource and b) how different components
interact within this landscape. Also discuss what information you need for managing these
resources.
Choice of natural resources to manage (choose one):
Water resources
Game
Grazing
Protected species
QUESTION 4: Evidence-based management:
[40]
To effectively manage an ecological problem, one needs to find the root cause of the
problem and apply a holistic approach to solving the problem. Opuntia stricta is a major
invader in Namibian savannas. To manage the problem effectively, if you were assigned to
prepare a management plan, what information do you need to prepare such a
management plan? Where can you source such information? How trustworthy are such
information sources?
