When I read about Preservation, Conservation and Restoration of Ecosystems, I wanted more than textbook definitions. I volunteered at a mangrove rehabilitation site where we replanted seedlings in cleared mudflats. That in situ restoration taught me how mangroves stabilize shorelines, filter nutrients, and provide nurseries for fish—a living example of ecosystem services.
In contrast, visiting a botanical garden’s seed bank demonstrated ex situ conservation. I watched curators store seeds of rare orchids at low humidity and temperature. Comparing both approaches made clear: preservation (setting aside protected areas), conservation (sustainable use and management), and restoration (active repair) all play distinct but complementary roles.
Sample SPM Question
“Differentiate between in situ and ex situ conservation, and give one example of each.”
My concise answer:
- In situ: conserving species in their natural habitat (e.g., Taman Negara National Park).
- Ex situ: conserving species outside their habitat (e.g., seed banks at FRIM).
