Main Issues
 Process to build up a National Strategy
Rapistrum rugosum
to approach the invasive species
problem in Mexico.
 National Information System on
Oreochromis mossambicus
Lablab purpureus
Invasive Species for Mexico.
International Commitments and
Conabio
Convention on Biological Diversity
•Article 8. In situ Conservation
•(h): Prevent the introduction of, control or eradicate those
alien species which threaten ecosystems, habitats or
species;
CONABIO is the National Focal Point of the Clearinghouse
Mechanism derived from the CBD
CONABIO is responsible of implementing the National
Biodiversity Information System, which includes the Invasive
Species Information System
Process to build up the Mexican National Strategy to
address the problem of Alien Invasive Species
Biological and socioeconomical
problems generated by AIS
Aquatic environments
Terrestrial environments
Conceptual framework
Strategic responses and actions
Five workshops, with 50 experts from 42 academic
institutions, governmental agencies, ngo, and industry, have
already been done.
Five more workshops are needed to complete the
participatory process.
Action Plan
1. Definitions
2. Criteria to characterize alien invasive species
3. Sources and pathways
Conceptual
Framework
•Terrestrial Species
•Aquatic Species
4. Establishment
5. Dispersion
6. Impact
•Biodiversity
•Agroforestry and range activities
•Fisheries
•Health
•Tourism
•Other related economic activities
Strategic responses and
actions
Diagnosis of the problems generated by AIS
Preventive Actions
Early warning
Management (eradication and control)
Informatics, research, and monitoring
Public awareness and education
Regulatory measures and policies
Inter-governmental cooperation
Five more workshops will be carried out with
governmental agencies, educational institutions,
ngo, and policy makers to end up the participatory
process
Pathways for aquatic invasive species and species
selection
Pathways
Aquaculture / mariculture
Pet, aquaria, ornamental plant
Cichlasoma cyanoguttatum
Ballast waters

Invasive Species Information System
Systematize and compile the available
information
concerning invasive species for terrestrial and aquatic
environments.
Obtain species checklists for each biological group and
define priority species to develop specific ecological
studies.
Determine the current geographical
distribution of the
invasive species and its potential ecological niches in
Mexico.
Develop risk assessments for biodiversity
Define strategies to manage these species with all
stakeholders, mainly with the responsible Ministries.
Caulerpa taxifolia
Invasive Species Information System
State of Art
Checklists of exotic and traslocated species
Rana catesbeiana
Species ecological information
•861 vascular plants
•60 mammals
•25 birds
•10 amphibians and reptiles
•76 fishes
•6 crustaceans
•6 mollusks
Distributional maps of the invasive species native range and potential
niches of their distribution in Mexico
Risk analyses for biodiversity (early detection and warning)
Potential distribution
of coffee crops
Ceratitis capitata
Prototype for aquatic
invasive species
Oreochromis mossambicus
Risk Assessment
Risk assessments for early detection and warning
Species identification and characterization of its native range of
distribution
Obtaining specimens information (localities where these have been
sampled) in scientific collections
Model potential ecological
niches with predictive tools
Validation with experts
Document main features of the sources and pathways of the potential
invader and of its establishment and dispersion phases
Technical report
Discuss strategies with involved authorities
Preventive Risk Assessments
Risk assessments are done in collaboration with the Ministries of Agriculture (Sagarpa),
Environment (Semarnat), and Health (SS).
Several case studies have been worked out with Sagarpa, and also with Semarnat and SS:
•Opuntia-Cactoblastis
•Bombus
terrestris
•Mediterranean
•West
cactorum -Most successful case study
fruit fly, Ceratitis capitata
Nile Virus
Potential overlapping areas between the Opuntia and the moth, Cactoblastis
cactorum, in North America
Orange and yellow lines: Similar
ecological areas for the moth
Areas in blue: Species
accumulation of Opuntia
Participation with International
Initiatives

Constitute a national node and participate in the
international initiatives coordinated by the Global
Invasive Species Program (GISP).

Actions to create a regional node for North America
in collaboration with the USGS and CEC.
