Bioremediation is a process that uses microorganisms to remove contaminants from the environment, while the other options are all approaches to ecological restoration.

Active restoration aims to restore an ecosystem to its original state, while the other options are goals of other restoration approaches.

Passive restoration allows an ecosystem to recover naturally, while the other options are examples of active restoration.

Assisted natural regeneration aims to speed up the recovery of a degraded ecosystem, while the other options are goals of other restoration approaches.

Fertilization is not a common technique used in ecological restoration, as it can disrupt the natural balance of an ecosystem.

Prescribed burning is used to improve the health of a forest by removing dead and diseased trees, reducing the risk of wildfires, and creating a more diverse ecosystem.

Ecological restoration does not typically result in increased carbon storage, as the focus is on restoring the ecosystem to its original state, not on increasing its carbon storage capacity.

Community involvement in ecological restoration can provide funding, labor, and expertise, all of which are essential for successful restoration projects.

Climate change is not a challenge to ecological restoration, as it is a global phenomenon that is not specific to restoration projects.

Monitoring is essential for assessing the success of restoration projects, identifying and addressing problems, and providing data for future projects.

Carbon storage is not a common metric used to assess the success of ecological restoration projects, as it is not a direct measure of ecosystem health or function.

Adaptive management allows for changes to be made to restoration projects as new information is learned, ensuring that the projects are effective and efficient.

Urban restoration is not a common type of ecological restoration project, as it typically involves the creation of new green spaces rather than the restoration of existing ecosystems.

Ecological restoration is important for protecting biodiversity, improving ecosystem services, and mitigating the effects of climate change.
