Question 6The following is an example of the “novel ecosystem” approach:1 pointeradicating brown tree snakes in Guampreventing the spread of zebra mussels to the Hudson Riverallowing cedar stands to grow in the Galápagosall of the above

The "novel ecosystem" approach refers to the management of ecosystems that have been significantly altered in structure and function by human activities and are unlikely to recover their original state. This approach accepts these changes and focuses on managing the new, altered state of the ecosystem to maintain its functionality and biodiversity.

Looking at the options:

1. Eradicating brown tree snakes in Guam: This seems more like a traditional conservation approach, aiming to remove an invasive species and restore the ecosystem to its original state.

2. Preventing the spread of zebra mussels to the Hudson River: Again, this is a preventative measure to stop an invasive species from altering the ecosystem, which aligns more with traditional conservation approaches.

3. Allowing cedar stands to grow in the Galápagos: This could be seen as a novel ecosystem approach. If cedars are not a traditional part of the Galápagos ecosystem but are now thriving and supporting biodiversity, allowing them to grow instead of trying to remove them and restore the original ecosystem could be a novel ecosystem approach.

4. All of the above: As explained above, the first two options align more with traditional conservation approaches, not the novel ecosystem approach.

So, based on these analyses, the most fitting answer would be "allowing cedar stands to grow in the Galápagos".
