If disease were spreading through our native forests, if our trees were developing strange growths that hollowed them out, making them brittle in the face of each passing storm, would five years have slid by with the problem worsening by the day? That is exactly what is happening on Norfolk Island’s reef. Slowly, insidiously, it is dying and turning to slime.

Today's National Threatened Species Day post discusses the conundrum of Australia's threatened species list and the IUCN Red List as they relate to vulnerable and threatened species here on Norfolk Island in the Marine Park. How, for example, do we offer protections to something that hasn't been formally identified yet, let alone listed as threatened?

We have shaped Kingston, Norfolk Island, to suit our own ends, whether it is by draining the swamp, undertaking major earthworks, or by using it for agriculture and grazing. Our interventions have placed the reef at risk. But simultaneously, the confluence of human activity and a unique natural environment have created a place of incredible significance, which deserves some special management to preserve all its facets.

More reports to add to a long catalogue of reports were delivered to the general public over the last few days on Norfolk Island’s water quality and reef health. Reassuringly, they all say the same thing. Our poor water quality is affecting the health of our reef. So the science must be good! So when are we going to do something about it?

This month, I have increasingly noticed a disease that is presenting differently to the white syndrome that we have sadly become used to seeing. With this disease the coral goes grey-ish black and sometimes looks like it is almost dissolving or melting away. The result is a tragedy for the coral. I talk to coral health researcher Associate Professor Tracy Ainsworth about what is going on.
Read MoreA year in review – 2023 on Norfolk Island's reef
Sadly, the year didn’t bring any obvious improvements to Norfolk Island's reef in terms of reductions in incidences of coral disease, or runaway algal growth. And while some fish seem to have departed the scene, another species has re-established its home. Here’s a rundown of what I've been doing during the last four years of observations, and what I've seen happening on our reef in 2023.
