Cycas edentata

Although Cycas edentata has a wide distribution from the Philippines to Northern Java and Sumatra, it is nowhere common and in many places already locally extinct. Subpopulations across almost all locations have declined dramatically over the past decade. The population size is currently thought to number about 5,000 mature individuals and is declining, in some places very rapidly.

INDONESIA:

Java - less than five subpopulations known and all severely impacted by the invasive Aulacaspis cycad scale, removal of plants for the ornamental trade, and habitat destruction.

Bali - the single wild subpopulation is locally extinct; and the Aulacaspis scale abounds on cultivated plants.

Sumatra - southern subpopulations were badly hit by the tsunami, northern subpopulations are probably the best extant subpopulations of the species, with no scale seen in the wild.

SINGAPORE:

Confirmed extinct in the wild (see Singapore Red list; Davison et al. 2008).

MALAYSIA:

Large scale removal of plants for landscape use, including export to Singapore, has resulted in only scattered plants left in small subpopulations; the subpopulation on Lankawi has been confirmed as extinct.

Sarawak - still extant in small viable scattered subpopulations.

THAILAND:

Less than five subpopulations left and each consists of less than ten plants.

VIET NAM:

Only known from a single population and current status not confirmed.

PHILIPPINES:

A large number of subpopulations have recently been visited but almost all have declined dramatically from collecting for the ornamental trade and/or severe habitat destruction.

MYANMAR:

No data are available.
