NatureServe Status

Global Status: G3
Global Status Last Reviewed: 24Apr2018
Global Status Last Changed: 24Apr2018
Ranking Methodology Used: Ranked by calculator
Rounded Global Status: G3 - Vulnerable
Reasons: Chrysopsis floridana is a restricted Florida endemic, with 39 extant occurrence records. There is limited potential for finding new populations due to residential development around the Tampa Bay area and phosphate mining and farming in rural portions of its range. Since 1984 many new populations have been found and most of the larger natural populations have been protected on conservation lands. Since 2008 seven new occurrences have been introduced on public lands which have doubled the total estimated number of plants. Plant numbers have increased at all but one of these introductions since they were first planted.

NatureServe Global Conservation Status Factors

Range Extent Comments: Chrysopsis floridana is a Florida state endemic. It occurs in Hillsborough, Manatee, Hardee, and Highlands Counties. Historically it is known to occur in Pinellas county. Included in range calculation were 10 introduced occurrences on sites where the species was not known to occur naturally, but were thought to have been within its natural range and habitat.

Area of Occupancy: 26-125 4-km2 grid cells
Area of Occupancy Comments: All extant natural and introduced occurrences were included in the calculations for Area of Occupancy

Number of Occurrences: 21 - 80
Number of Occurrences Comments: There are thirty-nine extant occurrences, of which 29 are naturally occurring and 10 are introduced.

Population Size Comments: The estimated global population size is 46,000 individuals, of which 21,000 are naturally occurring and 25,000 are introduced.

Number of Occurrences with Good Viability/Integrity: Some (13-40)
Viability/Integrity Comments: Nineteen occurrences have good viability. Of these, 11 are naturally occurring and 8 are introduced.

Overall Threat Impact: High
Overall Threat Impact Comments: All but two (the introduced occurrences on Mackay Creek and Paynes Creek Historic Park) of the 32 occurrences are on publicly owned lands that are managed to preserve the natural habitat. Dense residential development on the borders of four conservation lands in Hillsborough County has restricted the use of fire which is used to prevent the shading of the species. Manual thinning has been substituted for fire in these cases. Three occurrences in Hardee County on private land are at risk for agricultural or residential development.

Short-term Trend: Relatively Stable to increase of <25%
Short-term Trend Comments: Introduced occurrences on managed conservation lands in 2008 and 2013 have roughly doubled the global population size, according to rough estimates as of 2015. A demographic study comparing introduced and natural populations is now in progress (2017 to 2019), and is conducted as a cooperative project between Archbold Biological Station (Eric Menges), Bok Tower Gardens (Cheryl Peterson), and the US Fish and Wildlife Service.

Long-term Trend: Decline of <30% to relatively stable
Long-term Trend Comments: Since the species was first described in 1901, an unknown percentage of the population has been eliminated by rapid residential development in the Bradenton area of Manatee County and St. Petersburg portion of Pinellas County. The 30% decline upper bound is based on the area occupied by well-drained soils in Pinellas County (according to the Natural Resource Conservation Service soil map) compared to area of well-drained soils in counties where the species is known to occur.
