Ecological Mitigation Services

What is Ecological Mitigation and When is it Required?



In Ecology, mitigation is a method used to lessen the impacts of a development project within the vicinity of the development site. Mitigation projects should be carried out following the completion of protected species surveys and assessments, to understand which species and habitats are present and their potential impacts as a result of the development.

Mitigation measures usually take place to ensure compliance with wildlife legislation and best practice guidelines and are conditions of planning permission.

For certain species, protected by law, it may be required to obtain a Natural England licence for a development to proceed lawfully, and the mitigation should comply with best practice guidelines.

Carrying out mitigation will satisfy local concerns and planning legislation regarding the impacts on wildlife caused by proposed developments. It will also help to ensure no net loss of biodiversity as a result of projects, and help achieve a Biodiversity Net Gain as per policy.


Types of Ecological Mitigation

There are different types of Ecological mitigation, including avoidance, mitigation, and compensation. These types of mitigation follow best practice guidance and The Mitigation Hierarchy.

Avoidance – This is a type of measure taken to ensure that adverse impacts are avoided completely. Avoidance methods can include ensuring the timings of works are set to ensure that the site is not disturbed during sensitive times, like bird breeding season. Development projects should always assess if impacts can be completely avoided before exploring other mitigation measures as per the below.

Mitigation – This type of strategy refers to the measures taken to minimise the adverse impacts caused by a project on a site. Mitigation will usually involve using Precautionary Working Methods to facilitate development, moving a species via a translocation, and providing an enhanced habitat for species post-development. Other types of mitigation strategies include the creation of tunnels under roads to allow wildlife to cross from one side to another.

Compensation – This type of mitigation strategy is taken to counteract any damage caused by a development, in the event that mitigation and avoidance cannot take place. Compensation measures can include habitat creation or enhancement of important habitats. Compensation should be used as a “last resort” approach, and typically a surplus of resources for a species should be provided compared to what has been lost.
