Category 2 RARE Not under immediate threat of extinction, but occurring in such small numbers and/or in such a restricted or specialized habitat that it could quickly disappear. Category 3 DEPLETED Although still occurring in numbers adequate for survival, the species has been heavily depleted and continues to decline at a rate that gives cause for serious concern. Category 4 INDETERMINANT Apparently in danger, but insufficient data cur- rently available on which to base a reliable assessment of status. Needs further study.
