Ecological studies and inventory Biological Diversity

At environmental dimension company, we provide the service of preparing ecological studies and accounting for biodiversity in project areas and environmentally sensitive sites, in order to identify the components of the ecosystem, document plant and animal species, assess the state of natural habitats and the extent of their impact on proposed or existing activities.

The study helps the project owner and the design team to understand the environmental sensitivity of the site, identify priority species and habitats, and develop realistic measures to avoid, minimize impacts or restore affected sites, supporting environmental planning, sustainability and related study and permit requirements.

Implementation of an ecological study and inventory of biodiversity at a project site Field survey and assessment of natural habitats
A study based on the characteristics of the site and the survey season

Species groups, survey methods, the number of visits and their periods are determined by the nature of the habitat, the area of the site, the stage of the project and the requirements for the study.

Direct answer

What are ecological studies and biodiversity inventory?

Ecological studies are scientific studies that analyze the components of the ecosystem and the relationships between living organisms and their habitats, while Biodiversity Inventory focuses on monitoring and documenting plant and animal species present in a specific range, assessing the state of their habitats, their sensitivity and the importance of the site in terms of conservation. The results are used within environmental impact assessment , spatial planning, management plans, restoration and environmental monitoring.

Timing of the study

When does the project need Ecological study

The importance of the study increases when the project is located near natural habitats , canyons, coasts, wetlands or protected areas, or when the proposed activities are capable of changing land use, fragmenting habitats or disturbing fungal species.

Choosing a new project location

To compare alternatives and identify areas of environmental sensitivity before installing project boundaries or adopting the master plan.

Construction and infrastructure projects

When the works involve the removal of vegetation cover, excavation , backfilling, roads or service lines that may affect the habitat or movement of species.

Coastal and marine projects

To assess coastal or marine habitats, tidal zones, reefs or seagrasses when applicable to the site.

Mining, Quarries, and Crushers

To document the ecological baseline, identify affected habitats and establish management, restoration and rehabilitation requirements.

Agriculture and water projects

When vegetation, surface waters , wet areas or associated species may be affected.

Impact studies and permits

When the scope of the environmental impact study requires basic data on species , habitats, impacts and protection measures.

Scope of limitation

What can it include The biodiversity survey

Target groups are selected according to the nature of the site, habitat and expected risks, and not every project needs to include all groups.

Frequently Asked Questions

Questions about ecological studies Inventory of Biological Diversity

Is one visit enough to count biodiversity

It depends on the area of the site, the variety of habitats, target groups , season and stage of the project. A visit for an initial examination may suffice, while a baseline study may require multiple visits or seasonal surveys.

When is the best time to carry out an ecological survey

The right time varies depending on the region and the target group. The flowering season may be more favorable for plants, while surveys of birds , reptiles and mammals are associated with different seasons and times of activity.

Does the study include endangered species

The study includes reviewing the conservation status of registered species according to appropriate national and international data and references, and identifying priority , protected or sensitive species when they exist.

Are samples taken from plants or objects

It depends on the methodology of the study, scientific need and systemic requirements. Priority is given to harmless methods of documentation, samples are collected or objects are handled only in accordance with the applicable procedures and approvals.

Does the service include the preparation of biodiversity maps

Outputs can include maps of habitat units, monitoring sites , sensitivity zones and overlaps with project elements, depending on the quality of the data and the agreed scope of work.

What happens when a sensitive species or habitat is detected

The discovery is documented, its significance, location and the expected impact are assessed, then actions are proposed that begin with avoidance, such as adjusting the boundaries or route, and then minimization, restoration and follow-up actions when needed.

Is it possible to review a biodiversity study prepared by another

Yes, the survey methodology, timing, spatial coverage , species lists, maps and impact assessment can be reviewed, with gaps identified and additional surveys proposed.

What data is required to get an art show

It is preferable to provide the project location, its boundaries, area, type of activity , Project Stage, general plan, schedule, any impact study or previous survey , and the requirements of the entity or the financier, if any.

Is the save status used in the IUCN list within the study

They can be used as an international reference for the global conservation status, along with available national sources and local data. The global situation alone does not preclude the assessment of the importance of the species and habitat within the project site.

Can a biodiversity monitoring plan be prepared after the study

Yes, indicators, locations, monitoring periodicity , implementation responsibilities, alert limits and corrective actions can be prepared according to the priority impacts, species and habitats.
