Frogs are on the edge. Blasted by habitat loss, pollution, and a

terrible disease, the chytrid fungus, species are vanishing worldwide and

those that remain are clinging to existence, rather than thriving. However,

an interview with Pierre Fidenci, President of Endangered Species

International <http://www.endangeredspeciesinternational.org/index.php>(ESI),

proves that there are still areas

of the world where amphibians remain in abundance.

 

South Korea is not a country that is talked about frequently in conservation

circles. Other nations in the region attract far more attention, such as

Malaysia and Indonesia. But it was just this neglect that drove Pierre

Fidenci to visit the nation and survey the amphibians there.

 

" We have little information about the amphibians of Korea, " Fidenci

explains, " but, most importantly, I was very keen to look at a country that

is covered by 65 percent forest, including numerous rice paddies, which are

used by many frogs and salamanders. Many of my surveys and conservation work

has occurred in places in the world where deforestation is rampant and

forest coverage is less than 10 percent, especially in the tropics. "

 

 

Pierre Fidenci.Fidenci was able to observe many of South Korea's 18

amphibian species in the wild and what he found was generally positive.

South Korea's large percentage of forest cover " provides essential natural

habitat for amphibians in general, " while there are still " a good

number ofrice fields and creeks that also support amphibians, like the

Amur Brown

frog, for breeding and foraging. "

 

But what about the chytrid fungus, which has devastated so many amphibian

populations?

 

" Korean scientists have already found the chytrid fungus and

populations ofthe introduced bullfrog, carrier

of the chytrid fungus, occur in South Korea. However, at the present time,

there is no evidence at all that the chytrid fungus is impacting amphibians

in Korea, " Fidenci said, adding that " bullfrogs are localized in few areas

and have difficulties expanding their range probably due to the lack

ofadequate habitat and corridors, and a past campaign to eradicate

them. "

 

Part of the success of amphibians in South Korea, Fidenci believes, is due

to the way the country has grown—upward rather than outward.

United States and Europe where we build houses to live in which I call the

'horizontal process', whereas in South Korea we see a 'vertical urbanization

process' by building very high apartment buildings and no houses! " This has

left far more intact natural habitat available for amphibians and other

species.

 

One concern that remains for Fidenci is the affect of air and water

pollution on South Korea's frogs. Although he saw little direct evidence, he

says that " new research is needed " .

 

Fidenci's trip to South Korea was very much in character, since as President

of ESI he has steered his organization to work with little-known species

that other conservation organizations have overlooked. He says such

conservation efforts are difficult due to a lack of awareness, data, and

financial support.

 

" As you know people like to support emblematic species like the panda or the

mountain gorilla. But at ESI we need to keep working on 'forgotten' species,

we cannot have our decisions dedicated by conventional public interests but

by science and urgency, " he explains.

little known species he has gathered rare footage of some truly wonderful

subjects (videos at the end of the article), including the Philippine's

'white squirrel' whose taxonomy is still being studied, and the tarsier.

 

Mongabay.com spoke with Pierre Fidenci about his recent trip to South Korea

and his work as President of ESI.

 

 

 

*Mongabay:* *What is your background? How did you become interested in

amphibians?*

 

*Pierre Fidenci:* I was born and raised in southern France. I conducted my

undergraduate and graduate studies in France and the United States. Since a

very young age I was fascinated by amphibians and reptiles. At the age

of12, I spent quite some time between school breaks observing

frogs, snakes, and turtles. At the age of 18, I created a small organization

to promote conservation of amphibians and reptiles in France. My interest

for amphibians emerged quickly from my passion for nature.

Pierre Fidenci.*Mongabay:* *You recently traveled to South Korea to assess

the state of amphibians in the country. Why did you choose South Korea? *

 

*Pierre Fidenci:* Well, several reasons! First as a westerner we have little

information about the amphibians of Korea, but, most importantly, I was very

keen to look at a country that is covered by 65 percent forest, including

numerous rice paddies, which are used by many frogs and salamanders. Many of

my surveys and conservation work has occurred in places in the world where

deforestation is rampant and forest coverage is less than 10 percent,

especially in the tropics. The choice of South Korea was made due to a mix

of great curiosity, particular environmental conditions, and lack of

information available on the country's amphibians.

 

*Mongabay:* *What are some notable amphibian species in South Korea? *

 

*Pierre Fidenci:* There are 13 frog and five salamander species. Many

species (eleven of them) live in mountainous areas which include all

salamanders. The rest mostly breed in agricultural areas amongst rice

paddies and small streams. As far as notable amphibians, I'd like to cite

the oriental fire-bellied toad (*Bombina orientalis*), a very common species

that fascinates me; the Suweom treefrog (*Hyla suweonensis*), endangered and

endemic to Korea; the endangered boreal digging frog (*Kaloula borealis*)

which spends most of its time underground not too far from rice fields; the

Amur Brown Frog (*Rana coreana*) endemic to Korea; the endangered gold

spotted pond frog (*Rana plancyi chosemica*) surviving in localized areas

sometimes very urbanized; and finally the only Asian and endemic

plethodontid, the Korean crevice salamander (*Plethodonid Karsenia koreana*).

 

 

*Mongabay:* *What are your general findings from your survey? *

Fidenci.*Pierre Fidenci:* Well, first we were very happy to observe most of

the amphibians in the field thanks to the great information shared by Park

Daesik, a Korean herpetologist. Two species of amphibians are classified as

endangered: the boreal digging frog and the gold spotted pond frog, both

threatened by habitat destruction and degradation. Overall, compared to

other countries, South Korea has a very good natural coverage of forest (65

percent) and therefore provides essential natural habitat for amphibians in

general. In addition, even though many rice paddies are being replaced by

urban developments, we still have a good number of rice fields and creeks

that also support amphibians, like the Amur Brown frog, for breeding and

foraging. Since habitat destruction and degradation are one of the main

threats to amphibian worldwide, in this regard, overall South Korean’s

amphibians are in a good shape.

 

*Mongabay:* *Has the chytrid fungus hit South Korea’s frog species yet? *

 

*Pierre Fidenci:* Korean scientists have already found the chytrid fungus

and populations of the introduced bullfrog, carrier of the chytrid fungus,

occur in South Korea. However, at the present time, there is no evidence at

all that the chytrid fungus is impacting amphibians in Korea. Further,

fortunately bullfrogs are localized in few areas and have difficulties

expanding their range probably due to the lack of adequate habitat and

corridors, and a past campaign to eradicate them.

 

*Mongabay:* *Why do you think South Korea’s amphibians are doing well,

whereas around the world amphibians are declining drastically with many

species going extinct? *

 

 

*Hyla japonica*: The Japanese tree frog was used for traditional medicine in

South Korea. Photo by: Pierre Fidenci.*Pierre Fidenci:* In general, South

Korea’s amphibians appear to be doing well because of the persistence of

wide suitable natural habitat. Urbanization does not occur the same way as

in the United States and Europe where we build houses to live in which I

call the " horizontal process " , whereas in South Korea we see a " vertical

urbanization process " by building very high apartment buildings and no

houses! If you would just take 50 percent of those people living in

apartment buildings and build them houses with gardens, you will see a

tremendous loss of natural habitat.

 

As far as the impact of air pollution on South Korea’s amphibian, it is

unknown. New research is needed to assess the anthropogenic impacts via air

and water pollution on amphibians like the use of herbicides in rice fields.

Laboratory studies have shown the negative effects of agricultural chemicals

like endosulfan, but we do not know how it is translating in the field. We

did observed a lot of amphibians successfully breeding in some rice fields

using herbicides.

 

*Mongabay:* *Do you believe climate change is having an impact on amphibians

in South Korea? *

Fidenci.*Pierre Fidenci:* That’s a good question. Scientifically, I cannot

say that climate change is impacting South Korean amphibians, we don’t have

evidence as such. We are lacking considerable amount of data and as I said

earlier most of amphibian species are still doing well in South Korea! I

believe that we may start to observe an impact in the near future. For now,

the current biggest impact is habitat loss and probably air pollution from

Seoul and China, but we have not evidence on that either.

 

*Mongabay:* *How do locals in South Korea view frogs and other amphibians?

Are any of these species subject to hunting for food or medicine? *

 

*Pierre Fidenci:* In general, Korean have a good view of amphibians

including toads. Amphibians have long been used for food and traditional

medicine in rural areas. Some species like the Japanese tree frog and the

gold spotted pond frog were used for asthmatic conditions, fewer, and

infectious diseases.

 

*Mongabay:* *East Asia is in the midst of a biodiversity crisis with such

problems as high levels of deforestation, bushmeat and poaching for

medicine, growing human population, and climate change. How do you think

South Korea is faring with biodiversity—not just amphibian—compared to

neighboring nations? *

the problems as their neighbors besides of course climate change.

 

*ENDANGERED SPECIES INTERNATIONAL*

 

*Mongabay:* *You are currently founder and president of Endangered Species

International (ESI). How did you decide to start the organization? *

 

*Pierre Fidenci:* I was not satisfied with what I experienced as a volunteer

for other organizations. I wanted ESI to differ from other organizations and

make sure that we have a significant positive impacts on biodiversity. In

the past, I witnessed waste of funds and resources, lack of transparence and

honesty, difficulties to adapt with local communities, and more, and all

that troubled me. The core value of ESI is to tackle the problem at its root

(if we can identify it) and conduct conservation work with local people.

 

*Mongabay:* *What are the goals of your organization? How do you see ESI as

being different from other conservation organizations? *

Pierre Fidenci.*Pierre Fidenci:* The main goal is to reverse the trend of

human-induced species extinction by saving endangered animals and preserving

their wild places. Basically, we focus on preserving biodiversity. ESI is

different from other organizations because of the way we operate, we look

for and implement unconventional solutions to protect biodiversity, and we

must know the ground and the people better than anybody else. If you take

some large groups, they are governed by people who lose sense of the ground

reality, leading to failure or poor results. In the case of ESI, for

example, I know all our activities on the ground no matter where we are in

the world and from the birth of the project!

 

*Mongabay:* *Can you tell us about the ‘white squirrel’ and the Balabac

mouse deer, both of which are endemic to the Philippines? *

 

*Pierre Fidenci:* The white squirrel is found on a small island in the

Philippines. We are waiting for taxonomic results to see if it is a

different species or subspecies from the main island. They are not albinos

and most of them are white. The Balabac mouse deer is the world’s smallest

deer and occurs on small islands between Palawan (Philippines) and Borneo

(Malaysia). This deer is threatened by increasing hunting activities and

deforestation. The good news is that indigenous leaders and local

communities are fully supporting our project and ESI was the first

conservation organization accredited in the area!

 

*Mongabay:* *Is it difficult to receive support when you are working with

species that few people have heard of, but are truly at the edge of

extinction? *

*Pierre Fidenci:* Very difficult indeed! As you know people like to support

emblematic species like the panda or the mountain gorilla. But at ESI we

need to keep working on " forgotten " species, we cannot have our decisions

dedicated by conventional public interests but by science and urgency.

 

*Mongabay:* *What have been some of the greatest successes of ESI? *

 

*Pierre Fidenci:* Your question is important because we need to hear success

stories that will encourage us to move forward. We have successes, but let’s

be honest, they are hard to obtain and most of the time a project will

become a success after decades of hard work, not in one month or year! Some

of the important ESI achievements are changing behavior in kids we have

worked with, replacing illegal hunting by sustainable alternatives,

providing knowledge and leaderships to young conservationists in the

tropics, creating reserves, and protecting endangered animals.

 

*Mongabay:* *You have some great footage or rare and unusual animals on

YouTube. How do you capture it? *

Fidenci.*Pierre Fidenci:* It is not easy! First, you need to know the

ecology very well of your animal that you are targeting. You need a lot

patience and some luck too to get a good footage! Finally, most of the time

you need to have a local who will guide you throughout the jungle or the

ocean! It is always a great satisfaction to get a good footage that can be

used to promote conservation and change the way people see the world.

 

*Mongabay:* *Do you think the global extinction crisis is worsening or

improving? *

 

*Pierre Fidenci:* The global extinction crisis is worsening, there is no

doubt about that! We keep losing species every day and many more are going

to the brink of extinction. But let’s not forget that there are great

success stories too, well, not enough of them I concede, but we can reverse

the tide and save ourselves and the biodiversity around us!

 

*Mongabay:* *With so many species requiring conservation efforts, how do you

decide where to put your focus? *

 

*Pierre Fidenci:* We put our focus depending on the degree of urgency (not

all endangered species have the same degree of extinction, some are much

more threatened), our experience and expertise, and the location (we tend to

go to places where no other conservation NGOs work). We focus on endangered

species found in various types of habitat and serving as protecting umbrella

to other endangered species and various wild habitat. Please join
