Invasive Species Survey


There are over 110 non-native and invasive species, often referred to as Schedule 9 species, within the United Kingdom and all are prevented from release into wild under Section 14 of the Wildlife and Countryside Act 1981 (as amended).


There are a number of animals and plants that have been introduced to the British Isles. Many of the species exist without causing a problem but some effect the growth, development and survival of the native species; these are “invasive” species. Due to the variety of species and the differences in behaviour and habitat preference, specific surveys are highly dependent on the species being surveyed for and the objective of the survey. HalpinRobbins have experienced ecologists capable of conducting a range of invasive species surveys*, each tailored to meet our clients' needs and project requirements.

Invasive species can cause significant harm to native wildlife, people and buildings, if left unchecked. There are some species, such as Japanese knotweed (Fallopia japonica) and Giant hogweed (Heracleum mantegazzianum), whose presence on site can restrict working practices as well as causing soil and materials to be classified as a controlled waste which require specialist disposal, increasing costs and project time-scales. Species such as Giant hogweed (Heracleum mantegazzianum) can also be injurious to the general public and site workers.

Invasive species surveys can be undertaken as "stand-alone" surveys, part of Preliminary Ecological Appraisals or as part of Ecological and Environmental Impact Assessments and the requirement to undertake an invasive species survey is usually determined during a Phase 1 Survey. Unfortunately these species can appear in almost all water and land areas, including those covered by concrete, so any project could need an invasive species survey.

The survey season for invasive species varies depending on the species and survey outcomes, although the preferred timing is between April and September when plants are growing more vigorously and most animals are active.
