Environmental information system
SIGEEI brings together species, occurrence records, impact assessments, priorities, and management actions in a public platform dedicated to conserving Brazilian biodiversity.
About SIGEEI
The Management System for Invasive Alien Species and Biological Invasions in Protected Areas supports the detection, recording, assessment, prioritization, control, and monitoring of biological invasions within and around protected areas.
Public information can be consulted without registration. Managers, specialists, and administrators sign in to the new platform to review evidence, record local status, and preserve an auditable history of decisions.
Science applied to management
SIGEEI transforms inventories, georeferenced records, impact assessments, and local knowledge into distinct decision layers. Every result explicitly retains its scale, source, and limitations.
Brazilian overview
A harmonized national review recorded 444 invasive alien species in Brazil: 254 animals, 188 plants, and two algae across terrestrial, freshwater, and marine environments.
The synthesis showed that 20% of first records occurred after 2000, reinforcing the need for a living infrastructure rather than static lists.
Zenni et al. (2024) ↗An occurrence retains its source, date, coordinates, context, and quality.
Establishment and local status require their own interpretation.
EICAT, priority, and management are related layers, but are not inferred automatically.
Priority combines species risk, invasion stage, and occurrence frequency.

1,296 relationships · 557 speciesView pathways and vectorsZiller et al. (2026) ↗Scope of the scientific catalogue
The catalogue brings together species confirmed as invasive in Brazil and species relevant to prevention, distinguishing national status from recognition within a protected area.
Recognized as invasive in the country based on versioned scientific sources.
Invasive elsewhere and relevant to introduction surveillance.
Present under containment, without confirmation of a free-living population.
A species–protected area relationship recognized by ICMBio, without automatically changing national status.
From evidence to management products
SIGEEI preserves the origin of records, applies explicit quality criteria, and offers different spatial perspectives.
GBIF data, consolidated records, and manual entries remain identified by source, licence, and quality.

Open reportsConnected knowledge
Taxonomy, occurrences, sources, and distribution across protected areas.
EICAT assessments and local status as distinct scientific levels.
Priorities for management, prevention, and early detection.
Management, monitoring, reports, and versioned decisions.
Alignment with official references
The platform incorporates the list recognized by ICMBio Ordinance No. 510/2025 and reproduces the criteria of the federal prioritization tool while retaining the provenance of every item of information.
