we protect, conserve, & restore FL's native plants and native plant communities

TERMINOLOGY TUESDAY 🌿
w/ the Florida Native Plant Society!

Terminology Tuesday features weekly short videos teaching you botanical vocabulary (and now ecological terms) to help you get to know and understand our Florida flora. From beginner basics to advanced botany, we will cover it all, Tuesday by Tuesday!

Population:
A group of the same species of organisms living in the same area.

Community:
A group of different species living in the same area. Specifically; natural communities are distinct and recurring assemblages of plants, animals, fungi and microorganisms naturally associated with each other within their physical environment. Communities are the biotic (living), component of an ecosystem; and exclude abiotic (non-living) factors such as temperature, minerals, humidity, pH, elevation, etc.

Ecosystem:
An ecosystem (or ecological system) consists of all the organisms and the physical environment with which they interact. Ecosystems include biotic and abiotic factors, and can be generalized or specific in scale.

Thanks for tuning in!
See you again next week 👋🏻

The terms of the week are all “secondary” taxonomic ranks below the rank of species;

Form:
The taxonomic ranking of a population within a species exhibiting noticeable morphological deviation (visible differences), but are not especially genetically or geographically distinct. The same form can occur naturally in populations of a species across different regions, so can be genetically isolated from one another (not genetically distinct).
Can be denoted in the Latin binomial with the abbreviation “f.”
Example: Sarracenia flava f. atropurpurea

Variety:
The taxonomic ranking of a population within a species that is both morphologically and genetically distinct.
Can be denoted in the Latin binomial with the abbreviation “var.”
Example: Rhododendron viscosum var. viscosum

Subspecies:
The taxonomic ranking of a population within a species that is morphologically, genetically, and geographically distinct.
Can be denoted in the Latin binomial with the abbreviation “ssp.”
Example: Opuntia mesacantha ssp. lata

Welcome back to 🌿 TERMINOLOGY TUESDAY 🌿 with the Florida Native Plant Society!

Today we are joined by Wes Knapp, Chief Botanist at Natureserve, a conservation nonprofit that uses biodiversity data to help prevent extinctions of species and elimination of habitat across America.

How do we rank the conservation need for each species?

The primary tool used to prioritize the conservation needs of individual species is the global and state ranking system used by NatureServe. The ranking system facilitates a quick assessment of a species’ rarity at both the global level and on a state level (since some species that are globally secure may have vulnerable populations within a state).

Species are assigned both a global (G) and state (S) rank on a scale of 1 to 5. A number of factors, such as the total population size, the number of occurrences, threats, etc., contribute to the assignment of global and state ranks. The information supporting these ranks is developed and maintained by the Natural Heritage Program and NatureServe.

These rankings are included on Wikipedia pages of individual species, on the Natureserve Explorer, the US Fish & Wildlife Service, US Forest Service, in Weakley’s Flora of The Southeastern United States, and many other sources.

G1: Critically Imperiled — At very high risk of extinction or collapse due to very restricted range, very few populations or occurrences, very steep declines, very severe threats, or other factors.

G2: Imperiled — At high risk of extinction or collapse due to restricted range, few populations or occurrences, steep declines, severe threats, or other factors.

G3: Vulnerable — At moderate risk of extinction or collapse due to a fairly restricted range, relatively few populations or occurrences, recent and widespread declines, threats, or other factors.

G4: Apparently Secure — At fairly low risk of extinction or collapse due to an extensive range and/or many populations or occurrences, but with possible cause for some concern as a result of local recent declines, threats, or other factors.

G5: Secure — At very low risk or extinction or collapse due to a very extensive range, abundant populations or occurrences, and little to no concern from declines or threats.

The state rankings (S) have the same definitions, but the number rank may vary depending on the status of that species within each state.

Thanks for tuning in!
See you again next week 👋🏻
