Criteria for Selecting Illinois'
Conservation Priority Species |
|
|
| The
Illinois Wildlife Action Plan is
using information on the distribution and abundance of wildlife species
in greatest need of conservation, as well as information on the extent and
condition of these species' habitats, to help identify geographic areas
providing high conservation opportunity. |
| The
following criteria are being used to select these priority species:
|
| 1. All
species listed as threatened or endangered in Illinois, including
federally listed species that occur within the State. |
| 2. Species
with a global conservation rank indicator of G1, G2, or G3. |
| 3. Species
is rare (small or low population size, density or range) or has
significantly declined in abundance or
distribution from historical levels. |
| 4. Species
is dependent upon a rare or vulnerable habitat for one or more life
history needs (breeding, migration,
wintering). |
| 5. Species
is endemic to Illinois, or the Illinois population is disjunct from
the rest of the species' range. |
| 6. Illinois'
population of a species represents a significant proportion of the
species' global population. |
| 7. Species
is representative of broad array of other species found in a particular
habitat. |
| 8. Species'
status is poorly known, but available evidence suggests conservation
concern. |
