Conservation Concern (cont.) 5. NC Population
What is the estimated number of adults
(a) 1–50 individuals
Size
within North Carolina?
(b) 50–250 individuals (c) 250–1,000 individuals (d) 1,000–2,500 individuals (e) 2,500–10,000 individuals (f) 10,000–100,000 individuals (g) 100,000–1,000,000 individuals (h) >1,000,000 individuals
6. NC Range Size
What is the estimated range size for the species in North Carolina? • If a species has distinct breeding and nonbreeding ranges in North Carolina, use the smaller range to determine a score. • Assign scores based on the most restricted area (range) within North Carolina over which the species is distributed (number of counties or HUCs) or where it is expected to occur
(a) [Terrestrial: 1–2 counties] or [Fish, Mussels, Crayfsh: 1–36 HUCs (12-digit)] (b) [Terrestrial: 3–5 counties] or [Fish, Mussels, Crayfsh: 37–90 HUCs (12-digit)] (c) [Terrestrial: 6–10 counties] or [Fish, Mussels, Crayfsh: 91–180 HUCs (12-digit)] (d) [Terrestrial: 11–25 counties] or [Fish, Mussels, Crayfsh: 181–450 HUCs (12-digit)] (e) [Terrestrial: 26–50 counties] or [Fish, Mussels, Crayfsh: 451–900 HUCs (12-digit)] (f) [Terrestrial: More than 50 counties (or statewide)] or [Fish, Mussels, Crayfsh: More than 900 HUCs (12-digit)]
based on habitat availability.
7. NC Population
What is the estimated short-term dis- tribution trend for the species in North Carolina? • Scores are assigned based on recent trends within the last 20 years that relate to the number of individuals throughout the species’ range in North Carolina • Assign scores based on the most restricted area (range) within North Carolina over which the species is distributed (number of counties or river basins or HUC12s) or where it is expected to occur based on habitat availability.
(a) Decline of >90%
Trend (short-term)
(b) Decline of 80%–90% (c) Decline of 70%–80% (d) Decline of 50%–70% (e) Decline of 30%–50% (f) Decline of 10%–30% (g) Relatively Stable (≤10% increase or decrease) (h) Increasing (≥10% increase)
