Summary

Pediocactus sileri is a rare species of cactus known by the common names Siler's pincushion cactus and gypsum cactus. It is native to southwestern Utah and northwestern Arizona in the United States. It is limited to a specific type of soil, individuals are often spaced far apart, and the species is threatened by a number of human activities such as off-road vehicle use, poaching, and uranium mining. This is a federally listed threatened species of the United States.

Cultivation

Grouped as a cactus or succulent by Cactaceae, which is usually but not always one kind of plant (archetype table). The table holds no figure for this group, which spans too much for one minimum, and no habitat climate is derived yet; no cold floor is given, and no prose comes from the table.

Nothing derived: no habitat climate for this species, and the archetype table has no figure for its genus or family.

Climate across the habitat

No habitat climate can be derived: Only 1 distinct land cell of the climate grid holds an in-range record; three are needed for an envelope.

Natural habitat

Native range as published by WCVP; the marker is where the records are densest and decides nothing.

Openly licensed records inside the range, framed on where they fall.

Map marker37.042, -113.422 · in the densest population, 99 records (100% of those in range)

Evidence usedThe map marker rests on all 99 georeferenced records inside the native range; the map shows only the 51 openly licensed ones, which alone would put the marker 2 km away. No climate envelope is derived for this species. 97 in-range records are placed to worse than 10 km and stay on the map but off the climate.
