Free ESA Ecological Restoration Questions and Answers

Question 1

What is the primary goal of ecological restoration?

Accepted Answer

Restore biodiversity and ecosystem functions

Answer

The primary goal of ecological restoration is to assist the recovery of an ecosystem that has been degraded, damaged, or destroyed. This involves not only bringing back native species (biodiversity) but also re-establishing the natural processes and functions that characterize a healthy ecosystem, such as nutrient cycling, water filtration, and habitat provision.

Question 2

Which of the following is an example of a passive restoration method?

Accepted Answer

Protecting natural processes and minimizing human impact

Answer

Passive restoration, also known as 'rewilding' or 'natural recovery,' involves removing or reducing the causes of degradation and then allowing natural ecological processes to drive the recovery. This often means minimizing human intervention, such as ceasing logging, grazing, or pollution, and letting the ecosystem heal itself over time. Protecting natural processes and minimizing human impact aligns with this approach.

Question 3

What is a critical component of ecological restoration success?

Accepted Answer

Restoration of native species and ecological processes

Answer

A critical component of successful ecological restoration is the re-establishment of native species and the restoration of the ecological processes they participate in. Native species are adapted to the local conditions and contribute to the ecosystem's resilience and functionality, while restoring processes like hydrology or nutrient cycling ensures long-term health. Focusing on these elements ensures a self-sustaining and functional ecosystem.

Question 4

Which of the following would be considered an active restoration practice?

Accepted Answer

Planting native vegetation and removing invasive species

Answer

Active restoration involves direct human intervention to accelerate or initiate the recovery of a degraded ecosystem. Planting native vegetation directly reintroduces desired species, and removing invasive species eliminates a major barrier to native plant and animal establishment. Both are hands-on efforts that actively shape the restoration process, unlike passive approaches or mere monitoring.

Question 5

What is an example of a primary ecological restoration challenge?

Accepted Answer

Invasive species management

Answer

Invasive species management is a primary challenge in ecological restoration because these non-native species can outcompete native flora and fauna, alter ecosystem functions, and prevent the successful re-establishment of desired communities. Their control or eradication often requires significant resources and ongoing effort, making it a major hurdle to restoration success.
