A new species of Macrocarpaea (Gentianaceae) from southeastern Ecuador
|
Ecuador is well known among biologists and conservationists as one of the
megadiversity countries, along with others in South America such as Bolivia, Brazil,
Colombia, and Peru. This northern Andean nation is exceptional in that so large a
number of animal and plant species are found in a relatively confined area. The smallest
of the Andean countries, Ecuador has a land area of approximately 276,840 km² and
covers only about 0.2 percent of the Earth’s land mass; continental Ecuador (excluding
the Galápagos Islands) is slightly smaller than the state of Nevada. With a human
population of about 14.5 million, Ecuador is also the most densely populated country in
South America. Two examples reveal Ecuador’s remarkable biological richness:
More than 1,600 bird
species are known from Ecuador, 18 percent of the world’s total of about 9,000 birds.
More than 17,300
species of higher plants have been documented from Ecuador, about seven percent of the
world’s total and about as many plant species as in all of North America north of Mexico,
an area more than 200 times larger than Ecuador. Many new plant species continue to be discovered in Ecuador every year, and the total number of higher plants in the country is
probably closer to 20,000.
For 30 years, the Missouri Botanical Garden (MBG) has carried out a collaborative
program of botanical research, capacity building, and conservation in Ecuador and,
since 1985, has stationed a curator-in-residence permanently in the country. From the
mid-1980s to the mid-1990s, MBG focused its work in the Amazon lowlands of eastern
Ecuador, which until then had been virtually unknown botanically. During the ensuing
decade, MBG’s geographic focus shifted to the Pacific region of western Ecuador,
including the rain forests of the Chocó region in the north and the dry forest region
farther south, as well as the montane forests on the slopes of the Andes. More recently,
MBG has concentrated its work in the Cordillera del Cóndor and the Cordillera de Cutucú
in southeastern Ecuador, a region whose flora also was almost completely unknown
before MBG began to work there. These mountain ranges form part of a
discontinuous chain of geologically complex sub-Andean cordilleras at the interface
between the Eastern Cordillera of the Andes and the Amazon lowlands that comprise
one of the most biologically diverse regions on Earth.

 New species of Symbolanthus, Cordillera del Cóndor |
The prospect of environmental degradation and habitat loss resulting from large-scale
mining poses an imminent threat to the Cordillera del Cóndor and is the greatest challenge
faced by the conservation initiatives in the region. The igneous formations of the Cóndor
are rich in minerals, particularly gold and copper. Small-scale gold extraction by individual
miners using traditional methods has been carried out in parts of the Cóndor and Cutucú for
decades, but the governments of both Ecuador and Peru have recently granted large mining
concessions, and proposals for large open-pit copper mines in the heart of the Cóndor range
have been put forth.
MBG’s program in Ecuador has four major goals:
Floristic inventory in
poorly known regions of Ecuador, surveys of forests using one-hectare tree plots, and
dissemination of results in printed and online publications
Application of scientific
information generated by the floristic research to conservation, including the development and
implementation of action plans for in situ and ex situ conservation of threatened plant
species and delimitation of priority areas within Ecuador for plant conservation
Capacity building for
science and conservation through training of Ecuadorian university students, professionals,
and community people
Development and implementation of programs devoted to conservation and sustainable development of ecosystems
and their constituent plants, including environmental management plans for protected areas
