Assessment Notes

Justification

Parmotrema crinitum is widespread and abundant across the tropical and temperate zones; although in parts of its range it is threatened by habitat loss and changes in land management practices, it does not qualify for any of the threat criteria and is therefore listed as Least Concern.

---

Geographic range

Parmotrema crinitum is a pan-tropical and pan-temperate lichen found across the Americas, Europe, Africa, Asia and Oceania.

---

Population and Trends

Based on its widespread and global distribution and breadth of ecological niches, the population size is inferred to be large and stable.

Population Trend: stable

---

Habitat and Ecology

This species is found in moist woodlands, forests, savannas and shrublands throughout the tropics and temperate zones, predominantly as an epiphyte on branches and trunks of shrubs and trees, but also on mossy rocks in humid situations.

---

Threats

Losses of this species occur as a result of logging, habitat conversion and improper habitat management (closure of canopy reducing available light or overgrazing/browsing resulting in lack of regeneration for new colonization).

---

Use and Trade

The artificial plant market results in minor incidental harvest on branches of shrubs for production of tall artificial plants with sinuous lichen-covered trunks.
