What is an Ecological Survey?

There is a wide scope of different assessments which constitute an Ecological Survey, these span from basic Ecological Scoping Surveys to more specific and detailed NVC (National Vegetation Classification), Hedgerow, Botanical, River Corridor, Protected Species, Invasive Plant Species and Ecological Assessments.

The most commonly accepted initial and baseline Ecological Assessment, however, is a Phase 1 Habitat Survey which includes the study, identification and mapping of important wildlife habitats. This allows for an assessment of a site’s ecological importance and significant habitat features (property, plot of land, established boundary area) and informs the necessity for additional survey work.

A breakdown of the different surveys within Ecology Surveys

The following will be a breakdown of the many different sub-categories of ecological surveys that you may have to take depending on the findings of your preliminary ecological appraisal, which is the first step of your ecological surveys. They are carried out to identify ecological constraints.

Preliminary Ecological Appraisal (PEA) – Phase 1 Habitat Survey

What is a Preliminary Ecological Appraisal (PEA)?

This is technically the only mandatory step in the entire Ecological Survey.

A Phase 1 Habitat Survey, or Preliminary Ecological Appraisal, is a biologist’s first look at an area’s ecological landscape. Think of it as nature’s ID card, showing what habitats and species are present. In a nutshell, an expert walks through an area, noting the plants, possible wildlife, and the general health of the environment. Our experienced survey work will capture and detail what does, what does not, and what may exist within the region.

Why take a Preliminary Ecological Appraisal?

To put it simply, it helps us make smart choices. Whether we’re planning a new building or protecting wildlife, this survey gives us essential info, helping us balance progress with nature preservation. Essentially, this will be foundational to what your ecological survey entails.

What if nothing is found during a Preliminary Ecological Appraisal?

If there are no ecological constraints found during a PEA, then you will not need to take any further ecology surveys, and the project can continue unhindered.

Protected Species Surveys

What are Protected Species Surveys?

Protected species are those considered important for the ecosystem or at risk of extinction. These can include anything from bats and great crested newts, to rare plants and insects.

Protected species surveys are a vital tool for conservation. They provide data on these species: where they live, their numbers, and their health. This information is crucial when planning projects that could affect their habitats.

How are Protected Species Surveys done?

Experts come in, using specialist techniques. They might set up night cameras, use acoustic equipment to record bat calls or perform a detailed hand search for certain plants. It’s a combination of patience, knowledge, and a lot of care!

What do Protected Species Surveys include?

  • Bats: scoping inspections, bat activity surveys for all species (including emergence, transect, swarming)
  • Birds: inspections, checks and surveys for nesting birds, breeding birds, migratory and winter birds, barn owls, vantage point surveys (VP), and building & tree inspections
  • Great Crested Newts (GCN): daytime/walkover inspections, pond assessments, Habitat Suitability Index (HSI), detailed surveys (torching, egg searches etc.), bottle trapping
  • Reptiles (all species): daytime inspections, presence/absence surveys, population surveys;
  • Badgers: daytime surveys, sett identification, nocturnal population surveys;
  • Dormouse: habitat assessment, hazelnut searches, presence/absence surveys (nest boxes);
  • Otters and water voles; daytime inspections, habitat assessment, presence/absence surveys (evidence-based);
  • Invertebrates – including white-clawed crayfish, stag beetles, daytime inspections, habitat assessment, and presence/absence surveys (evidence-based).

National Vegetation Classification (NVC) Surveys: A Quick Guide

What are NVCs?

An NVC survey is a comprehensive method of categorising vegetation within a specific habitat in the UK. It’s a tool vital for informed environmental management and conservation planning.

Such understanding is crucial in several ways. It informs sustainable land-use planning, aids in monitoring habitat changes, and supports the protection of biodiversity. This diligent process, therefore, plays a crucial role in effective environmental stewardship.

How are NVCs carried out?

Teams of ecologists walk through a designated area, systematically recording all the plant species they find. They take note of the types of plants and their abundance, creating a detailed picture of the vegetation. The data collected helps to classify the vegetation into various categories, hence the name ‘vegetation classification’.

Hedgerow Survey

What are Hedgerow Ecology Surveys?

Hedgerows are more than just boundary markers; they are vital components of our ecosystem. These green barriers offer habitats for a variety of species, aid in soil conservation, and contribute to the scenic beauty of our landscapes.

The process of conducting a hedgerow survey is quite meticulous. It involves examining the composition of plant species, assessing the structure, and noting any signs of wildlife habitation.

Conducting these surveys allows us to grasp the health of our hedgerows, informing conservation efforts, and ensuring these natural assets continue to thrive.

How are Hedgerow Ecological Surveys carried out?

Ecologists walk along hedgerows, checking their structure, and the variety of plants, and looking out for nesting birds or protected species. They’re assessing the health and value of the hedgerow to wildlife. This could involve checking for gaps, the range of plant species, and signs of animals.

The information collected helps to understand how to maintain or improve these crucial parts of our landscape.

Botanical Ecological Surveys

What is a Botanical Ecological Survey?

A botanical survey is a focused study where experts identify and record all plant species within a certain area. This helps us understand the health and biodiversity of that ecosystem, guiding decisions about conservation and environmental management.

Why do a Botanical Ecology Survey?

Well, understanding what plants are here helps us manage the land better. It gives us insights into biodiversity, lets us spot any rare or invasive species, and helps plan conservation efforts.

The benefits are pretty big. It’s not just about knowing our green friends better. These surveys can guide land use, influence policy, help conserve threatened species, and even tackle climate change.

How is a Botanical Ecological Survey conducted?

Typically, a team of botanists will explore an area, identifying and recording plant species. They might take samples for further study, map locations, and photograph species. It’s detailed, systematic work, but vital for understanding and protecting our natural world.

River Corridor Surveys

What is a River Corridor Survey?

A river corridor survey is a systematic examination of a river ecosystem. It focuses on the river’s physical attributes, surrounding vegetation, and biodiversity.

River Corridors and the Ecosystem

River corridors, the land areas adjacent to the river, are ecological lifelines. They promote biodiversity, assist in flood management, and maintain water quality.

How are River Corridor Ecology Surveys conducted?

River surveys are conducted by trained ecologists. They record details such as river shape, flow, vegetation types, and species present. This information is pivotal in managing and preserving our river ecosystems.

Invasive Plant Species Surveys

What is an Invasive Plant Species Survey?

An invasive plant species survey is a methodical inspection to detect and identify non-native plants. These plants, often introduced accidentally or intentionally, can harm the local ecosystem if unchecked.

How are Invasive Plant Species Surveys done?

The surveys are carried out by professional ecologists. They inspect the area and identify and map the location of invasive species. The collected data inform management plans to control or eradicate these species.

Examples of Invasive Plant Species

Invasive Plant Species are also part of the overall ecological survey. We regularly inspect and advise clients on the presence of invasive plants such as Japanese Knotweed (Fallopia japonica), Himalayan Balsam (Impations glandulifera) and Giant Hogweed (Heracleum mantegazzianum).

It is illegal to plant or allow the spread of plant species listed on Schedule 9 of the Wildlife and Countryside Act (1981). A list of plant species within Schedule 9 and guidance is available at and

Ecological Impact Assessments

What is an Ecological Impact Assessment (EIA)?

An Ecological Impact Assessment, or EIA, is a study used to understand the potential effects a proposed development might have on local ecology.

Conducting an EIA

EIA involves several steps. Firstly, ecologists assess the existing environment. Then, they predict how the planned development might impact this. They evaluate the severity and acceptability of these impacts and then suggest ways to mitigate them.

The Role of EIA in Mitigating Ecological Damage

EIA plays a crucial role in protecting our natural world. It allows us to balance development with the need to preserve biodiversity and ecosystems. Mitigation strategies suggested through EIA help in reducing or compensating for any potential harm.

Mitigation / Site Management

Whether it be local authority liaison, Natural England licence application, toolbox talks, site supervision, habitat creation or translocation, clear guidance by an appropriately qualified, licensed and experienced ecology consultancy ensures you receive the correct advice upfront.

Mitigation measures can include several strategies and options to limit the impact and effects of development on habitat and protected species. Planning the mitigation measures early in the proposed development site plan can benefit the development timeframe and will assist in supporting planning approval etc.

The mitigation options can include avoidance by design, incorporating and supplementing existing habitat into the design, integration of artificial homes (boxes, piles etc.), translocation of species to suitable natural habitats or habitat creation to enhance a site (meadows, ponds etc.).

Planning Developments

Working with ecology consultants is often a requirement from a local authority as part of a planning condition and application. As an applicant looking for planning permission on an area that may be impacted in terms of its natural habitat, you must present all relevant ecological information with your planning application, or at least soon after.

From the perspective of development, an ecological survey ensures that they are adhering to UK wildlife law and any obligations that they have as the lead developer, anticipating any questions that the local planning authority may have once a planning application is in process.

Staying ahead of the game in terms of surveying the immediate area of a prospective development can cut time and costs. If you are searching for ecological consultancy in the UK that can provide you with an in-depth study of an area, whether you are a developer, or looking to assist with a conservation effort, Indigo Surveys is the right team to call.

Our specialist ecology consultants are committed to ensuring that our service continues to improve at all times, offering a high level of quality and standards consistently.

What are the benefits of a full Ecological Survey?

An initial ecological survey will confirm the presence or absence of habitats and species and is vital before planning permission for a development can be sought. Through a habitat survey, any ecological constraints on a site will be identified at the earliest opportunity and can be taken into consideration with development plans to minimise the impact on biodiversity.

Identifying species on a site will help minimise disturbance to their habitat and ensure that appropriate mitigation, and potentially new habitats, can be created, thus smoothing the way for planning consent to be given. Having a survey completed is an essential part of the planning process and must be completed before putting in a planning application. 

Knowing the environmental impact any development may have, and all the relevant ecological matters regarding a site will help determine whether any further surveys are required. The identification of specific habitats, including those that may contain protected species such as bats, foxes, badgers, amphibians, or even protected plants, is key to ensuring that the right action is taken at the right time and projects are not unnecessarily delayed. 

Following the initial ecological survey, if no issues are identified, then no further surveys are usually required, and the ecological survey report can be submitted as part of the planning application. If something is identified, such as protected species, then further surveys will need to be arranged and an approach agreed upon to mitigate for impact on any habitats or species.

With any development required to create at least a 10% biodiversity net gain (BNG), this has made ecology surveys more important than ever before to ensure that binding environmental targets are met.

Overall, obtaining the correct information early on at the design stage of a project can save considerable time and reduce costs. While a Phase 1 Habitat Survey can be carried out throughout the year, there are restrictions on the optimum survey periods for some protected species, so factoring this in early can help you avoid costly delays and keep your development project on track.

Detailed surveys and reports enable our clients, the design team and associated personnel to have full information about the presence or otherwise of protected species on or adjacent to a site. The potential constraints imposed by the presence of protected species can often lead to delays, however, specialist advice from our specialist ecology consultants as early as possible in the process can save time and money.
