The Milky Silkpod (Parsonia dorrigoensis) is listed as 'vulnerable' in NSW and is a nationally endangered plant.

As the name suggests, the forests of the Mid North Coast are a stronghold for it, with most records found between Kendall and Woolgoolga.

In 1999 it was estimated that there were less than 2000 individual plants and the main threat to the survival of this species is low numbers.

Official government advice on how to manage the plant says that "searches for the species should be conducted prior to any logging operations" and known habitat should be "protect[ed] from clearing, high levels of disturbance and development".

"Yet once again Forestry Corporation has shown its disregard for the the environment," survey team member Jonas Bellchambers said.

"Of the 110 confirmed new records identified on the weekend, 39 specimens were found that had already been damaged and are unlikely to recover.

"With more logging and roading imminent it is highly likely to wipe out a good part of this population.

"Like for most species, it's a death of 1000 cuts, and before we know it another plant has blinked out and has gone from our planet completely. We are in the midst of a major extinction event. Here we have a clear example of why. Because government and industry just don't care.

"We call on the Environment Minister Matt Kean to take immediate action to ensure the protection of these endangered plants. Otherwise he will bear responsibility for the demise of the Milky Silkpod."
