These live on the soil surface in the litter layer. They break down organic mulch rapidly but do not burrow deeply.
Natural soil regeneration on such a hostile site could take up to 60 years. By using these specific worm varieties, the project aims to complete the process in just . Alongside the worms, around 250,000 trees, including willow and alder, have been planted. These trees perform a dual role: their roots extract remaining contaminants, and they can eventually be harvested for wood burning or manufacturing. Project Partners This rescue plan was developed by a collaboration between: HL Banks : A local landscaping and earthmoving company. Scottish Greenbelt : A regional developer.

Description of the long-term biological impact of earthworms →right arrow Paragraph E
Because the land was toxic, builders could not use it for normal brick-and-mortar housing. It sat abandoned for over a decade. Cleaning up the soil using standard mechanical methods would have cost more than £30 million, which was far too expensive. The Pioneering Low-Cost Rescue Plan
The first paragraph states that the worms will help turn the derelict site into “woodland and a renewable energy park.” “Renewable energy” is a key phrase that fits naturally in the blank. Make sure to copy the words exactly as they appear in the passage. Capitalisation is not required in your answer sheet. (Proposed by a local landscape company partnering with
: Within 20 years, this once-dead steelworks was completely transformed into a green, thriving community woodland and energy park.
The text is particularly valuable for IELTS candidates because it combines environmental science content with multiple reading skills: scanning for factual information, understanding cause–effect relationships, matching features to descriptions, and completing summary notes. The passage's clarity and logical organisation make it an excellent resource for understanding how applied biology can solve real-world pollution problems.
Global ecological projects have demonstrated that integrating earthworms into land reclamation schemes drastically shortens recovery timelines. For instance, on old coal mining spoil tips, researchers have found that introducing specialized earthworm populations alongside pioneering plant species (such as clover or hardy grasses) can form a functional, fertile topsoil layer within just a few years—a process that would naturally take centuries. (Offers a lower-cost alternative to traditional methods)
Paragraph 5 attributes the quote about soil binding and nitrogen directly to Sean Ince of Bell‘s biology department. The statement in the question paraphrases his words: “The idea is that earthworms will contribute in a cumulative way to further soil binding.”

The process of using worms to decontaminate soil is known as vermiremediation. This operates through three primary mechanisms:
Derelict sites—such as abandoned factories, former quarries, and disused landfills—present a severe environmental challenge. Centuries of industrialization have left behind vast tracts of land that are completely hostile to plant life. These sites typically suffer from:
