Final answer:
The correct answer is 'c. Monitoring' which refers to the systematic collection of data over time to manage and assess changes, particularly within the context of conservation management and biodiversity.
Step-by-step explanation:
Once project risk analysis has been completed, it is crucial to have a system in place for continued oversight and documentation. The correct answer to fill in the blank is c. Monitoring. Monitoring is defined as data sampling which is repeated at specific intervals over time for management purposes, is replicable, and focuses on the rates and magnitude of change. This process is essential as it plays a role in identifying priority areas for conservation, evaluating how plant and animal populations respond to disturbances, and guiding the management interventions. Hence, developing a reporting and monitoring system is vital for the effective management and conservation of biodiversity, and it is also a requirement for countries that are parties to the Convention on Biological Diversity.
