| Focusing on distribution or range, this survey was undertaken to determine the state of wild animals in Japan. The survey encompassed mammals, birds, amphibians, reptiles, freshwater fishes and insects. |
|
| ąŁ 2. Survey Content and Methods |
|
|
The items below were surveyed for mammals, birds, amphibians, reptiles, freshwater fishes and insects.
|
| Taxonomic groups |
Target Species |
Methods |
| Mammals |
8 species of wide-ranging medium and large
animals whose range overlaps in part with
areas of human habitation. |
Forest workers and wildlife protection specialists
(2,235) interviewed hunters (44,853)
in each
prefecture. |
| Birds |
257 species known to be or possibly breeding
in Japan. |
Survey sections were selected from the entire
area of the 47 prefectures. Two methods
were
used; a site survey and a survey of
existing
printed resources. |
| Amphibians & Reptiles |
34 species with limited distribution or which
are threatened with rapid reduction in numbers
or local extinction due to human activities
or which are scientifically important. |
Site surveys to the extent possible to follow
up and check documentary and interview
data. |
| Freshwater Fishes |
27 species with limited distribution or which
are threatened with rapid reduction in numbers
or local extinction due to human activities
previously selected by the Environment Agency,
44 species chosen by the individual prefectures. |
Site surveys, to the extent possible, to
verify documentary and interview evidence. |
| Insects |
Ten species selected by the Environment Agency
as representing relatively familiar and widespread
species and indicative of an ability to flourish
in environments ranging from mountains to
plains; and specific species in each prefecture
meeting selection standards. (50 - 100 species
per prefecture) |
With the cooperation of The Entomological
Society of Japan, Society members collected
data from print resources and made
site surveys
and interviews as necessary to cover
as large
an area as possible. |

Mammals were surveyed thoroughly all over the country and a detailed
distribution map was prepared. Findings are shown for each prefecture on a 1:
50,000 scale topographical map divided into 16 equal sections (Multiple-5 Area Grid, about 5km X 5km
grid), to indicate the distribution of each species over the entire country.
For birds, a distribution map showing the breeding areas of 205 of the
257-target species was prepared.
Likewise distribution maps were made
for amphibians, reptiles and freshwater fishes. Research specialists analyzed
biogeography and taxonomy, and the position of each species as to conservation
requirements.
The insect survey was done on 1,764 target species selected
by each prefecture. A nationwide distribution map was made for the ten-indicator
species chosen by the Environment Agency. Species circumstances as to
distribution and state were checked by research specialists. Using the indicator
species, environmental conditions in every prefecture were diagnosed.
