Snails: Ambassadors of Nature?
The lowly snail.
It's not soft, cuddly or pretty but Marty Meyer is hoping
it inspires high school students to love nature. Seem like
a hard sell? Maybe. But Meyer is counting on tiny endemic
snails to awaken if not a love, then at least a better understanding
of science and nature in students from Honoka'a High School.
Meyer, who is working on his Ph.D. in conservation ecology
at University of Hawai'i at Manoa, chose the snail to study
because so little information about snails exists. But time
is critical for the snail because species are going extinct
- falling prey to changing habitats, invasive plant species
and other threats - at a rapid rate. Meyer wants to collect
information about the snails and their role in nature before
it's too late.

"Land-snail faunas world-wide are under extreme threat
and have the dubious honor of having the highest number of
documented extinctions of any major taxonomic group,"
Meyer said.
Hawai'i was once rich with snail species but more than 90
percent of described Hawaiian land-snails are now extinct.
The first endemic Hawaiian snails were described by an explorer
in the 1800s, Meyer said. The explorer wrote in his journal
about a lei he received that was decorated with snail shells.
Since then more than 750 endemic species have been described.
"Snails used to hang from the trees like bunches of grapes,"
Meyer said. "They used to call the Hawaiian tree snail
a singing snail but the singing was actually coming from nearby
crickets."
As part of his Ph.D. fellowship, Meyer is tasked with putting
together an educational program related to his studies. He
is studying endemic snails - Hawaiian succineids - in the
cloud forest above Hilo. Finding a similar environment in
the Kohala Mountains and similar snails above Waipi'o Valley,
Meyer sought to partner with a local high school.
Honoka'a High School science teacher Rick Roper was interested
in the project and together Meyer and Roper began the arduous,
and as-yet unfinished, task of setting up the program.
First Meyer had to choose a study site. When access to his
first choice of sites off White Road was denied, Meyer found
an alternative site accessed via water department land. A
van pool was arranged and after two false starts, Meyer, Roper
and a group of college-prep biology students took their first
field trip to the study site in December.
Roper said the experience was exciting.
"The idea that students need time in the field is important,"
he said. "That's really where science is done - in the
field."
On their first visit, the students photographed and began
to identify the plants within the study area. Back in the
classroom, they'll work to develop a plant key which they
will use once the snail counting begins. On subsequent visits,
the students will mark off sections of study area and, leaf
by leaf, examine the plants for snails. The snails will be
identified and marked and their locations recorded. Counts
will then be taken at regular intervals allowing the students,
Meyer and other scientists to gather some basic data about
the snails: how many there are; what plants they prefer; if
they move about much; how long they live.
"This is what science is about;" Meyer said, "it's
about answering questions." And for the students, the
project is also about learning the processes involved in gathering
information aimed at answering those questions.
Ideally, the results of the project will be interesting to
the kids and scientifically relevant. Meyer hopes that once
the program is in place, it will continue after his involvement
is over in about three years.
Meyer is also teaching about the snails during an upcoming
class sponsored by The Kohala Center. As part of the Quest
for Hidden Jewels program in March, Meyer will lead
a hike and teach about endemic snails.
In the end, Meyer isn't looking to make snail lovers out of
students. But he does want them to learn to appreciate their
natural surroundings. If a snail can help him do that, all
the better.
"I'm not trying to make them all into scientists but
nature lovers would be good," Meyer said while examining
an ohi'a leaf, the bright sun glinting off snow-capped Mauna
Kea in the background.
