Cesar Vinha State Park covers 1,500 hectares and is
part of the Atlantic Forest Biosphere Reserve in Espirito
Santo. It was the first protected area in the state
to create an Action Plan for the control of invasive
alien species. Located in Guarapari, on the coast, it
protects sand dune formations, lowland atlantic forests
work started in March, 2007, with training provided
by the Horus Institute to protected area managers, involving
field practice that received press coverage at the national
listserver on biological invasions was implemented in
the state as a support tool. Protected area managers
at all levels participate in discussions. All protected
area managers filled out spreadsheets with data on invasive
alien species as a base for the action plans, which
are being incorporated in existing management plans
and implemented in the short term. The data collected
in protected areas was incorporated in the national
I3N invasive alien species database maintained by the
Horus Institute and The Nature Conservancy.
Cesar Vinha and Itaunas State Parks
invasive alien species were recorded in the Paulo
Cesar Vinha State Park during a survey carried
out in 2006/2007 with the Federal University of
main invasive alien species that threaten the
park biodiversity are acacia (Acacia mangium),
molasses grass (Melinis minutiflora),
kikuyu grass (Brachiaria humidicola),
brachiaria (Brachiaria decumbens) and
guinea grass (Panicum maximum). Giant
false agave (Furcraea gigantea) also
has high invasive potential as it reproduces through
gems which are wind dispersed.
removal and control of all invasive alien species
will be carried out by staff of the State Environmental
Agency (IEMA) with support from a private road
manager of Rodovia do Sol - RODOSOL. The Normative
Instruction IEMA 003/07, published in February,
2007, provides legal background for these activities,
in accord with the Federal Law 9985/00, which
establishes the National Protected Area System.
State Park, located on the Northern Coast of Espirito
Santo, also has an action plan already under implementation.
at Cesar Vinha Park
species of uncertain origin and suspected to be native
of Brazil, such as the hopbush (Dodonaea viscosa)
and brackenfern (Pteridium arachnoideum), receive
different treatment although they seem to invade some
of the habitats in these parks.
Native species which, due to disturbance, increase their
area of distribution are named opportunistic species
and are subjected to management tests to help define
best control practices. If biodiversity in these occupied
areas increases, management continues. If biodiversity
does not increas, other hypotheses are tested. But these
opportunistic species are never aimed for eradication
like alien species. The issue here is to find ways of
getting the environment back to its natural balance.
alien species in Espirito Santo state
of the invasive alien species under control in the state
- Acacia mangium
Native to Australia, it was introduced
to Brazil by the forestry industry. It has become
a serious problem in several states in Brazil because
it is an aggressive invader along the coast in Espirito
Santo as well as in the grasslands of Roraima, in
the Amazon region.
false agave - Furcraea gigantea
Native to Central and South America,
it was introduced in Brazil in the ornamental plant
trade. It invades coastal habitats and sand dune
formations, as well as clearings in forests.
almond - Terminalia catappa
to Malaysia, it was introduced as an ornamental
tree for shade and is very common in the Brazilian
beaches. Invades natural habitats in sandy areas
along the coast.
Management of the State Parks
Clearing invasive species is now a part of the routine
in the management of protected areas in Espirito Santo.
Many plants sprout after being cut and there is always
seed in the soil that germinates after control actions,
so it is crucial to keep up a monitoring system to repeat
control actions and ensure there is no reinvasion.
are often more difficult to eradicate and require controle
work in the long term.
you visit the parks in the state of Espirito Santo and
see field staff working with chainsaws to remove plants,
be aware that this is part of environmental management
and that these actions are essential for the conservation
you can help
not cultivate invasive alien plants. See

Never release pets in natural areas. They can
impact natural populations of animals and plants.
