18 Questions
What is the key difference between physiochemical and vegetative degradation?
Physiochemical degradation has a more severe impact on the soil and hydrological cycle compared to vegetative degradation.
Which of the following is an example of a 'catastrophic impact' that can degrade a forest?
A landslide or volcanic eruption
What is the 'restoration pathway' referred to in the passage?
The process of restoring a degraded ecosystem to its original, undisturbed state.
Which of the following is an example of a 'severe impact' that can move an ecosystem 'all the way down' the 'restoration pathway'?
Conversion to industrial oil palm plantations
What is the purpose of the 'stairway' analogy used in the passage?
To illustrate the different levels of degradation an ecosystem can experience.
What is the primary focus of the 'reclamation side of restoration' mentioned in the passage?
Rehabilitating the physical and chemical properties of the soil.
What is the main difference between restoration and rehabilitation?
Restoration aims to restore everything back to its original state, while rehabilitation focuses on rehabilitating core ecological processes.
Which term is used for the most severely degraded lands such as those impacted by mining?
Reclamation
What is the primary factor governing the level of rehabilitation needed for a particular area?
Social circumstance
Which term refers to the degradation of certain elements of the original vegetation structure or composition?
Degradation
Which restoration approach is considered nearly impossible and economically expensive?
Rain Forest Restoration
In what context might reclamation typically occur?
In severely degraded lands from activities like mining
What type of degradation is generally associated with chronic issues and relates to rehabilitation strategies that tweak the system?
Low severity degradation
In medium severity degradation, what kind of strategies are often associated with land conversion?
Strategies that only tweak the system slightly
What is a characteristic of high severity degradation systems that require remediation of the soil for restoration?
They have intact productivity despite changes in vegetation
Which restoration strategy is mostly associated with facilitating planting, changing vegetation, and competition between species through weeding?
Rehabilitation without manipulating the soil
What type of rehabilitation strategy involves not changing the hydrology or manipulating the soil but altering composition and facilitating planting?
Low severity rehabilitation strategies
Which level of degradation is often associated with small tweaks in system changes or protection but not significant alterations to hydrology or soil?
Low severity degradation
Test your knowledge on ecological restoration and rehabilitation strategies, including discussions on the concept of least severity degradation and its relation to tweaking natural systems for restoration purposes.
