seedbank_longevity_class

Label: Seedbank longevity class
Entity URI: https://w3id.org/APD/traits/trait_0030413
Type: categorical
Definition: A seedbank's [MESH:D000068098] longevity [EnvThes:22228], expressed as a categorical variable [STATO:0000252], where seedbank longevity is the time interval (duration [PATO:0001309]) a mature [PATO:0001701] seed [PO:0009010] remains in the seedbank, viable [PATO_0000169] and able to germinate [GO:0009845].;Categorical groupings indicating the length of time (duration) a mature seed remains in the seedbank, viable and able to germinate.
Additional comments: Seedbank longevity classes are a feature of a `population` (sample) of seeds, not an individual seed. Also see the traits `seedbank_longevity` (numeric trait), `seed_dormancy_class` and the trait `seed_recruitment_timing`.

Allowed values:

value	description
long_persistent	Seed that persists in the seedbank for more than 5 years, although the time interval varies by study.
persistent	Seed that survives in the seedbank until at least its second germination season.
short_persistent	Seed that persists in the seedbank for approximately 1 to 5 years, although the time interval varies by study.
transient	Seed that survives in the seedbank until its first annual germination season, but not until its second annual germination season. Some transient seeds will germinate within weeks to months, while others may remain in the seedbank for slightly over a year, depending on how the annual recruitment season aligns with seed maturation. Transient seeds are non-dormant, remaining in the seedbank until environmental conditions are appropriate for germination.
widely_dispersed	Seed longevity not important, as seeds are widely dispersed and always available for germination.
