How Are Companies Helping Fix the Reef?

Passions of Paradise

Passions of Paradise, a tourism operator in Cairns, has used this industry shut down to focus on various scientific partnerships. Besides providing survey data for the Great Barrier Reef Marine Park Authority’s Eye on the Reef program, Passions of Paradise has also become a vital partner in Sydney’s Coral Nurture Program at the University of Technology. It also spent the shutdown planting coral at two of its reef sites.

Coral Nurture Program

The Australian and Queensland Government Coral Abundance Challenge funded the project, The Coral Nurture Program, developed by a team of scientists consisting of Dr Emma Camp, Associate Professor Dave Suggett, Wavelength Owner John Edmondson, and PhD student Lorna Howlett. The team has collaborated with five tour operators in the Cairns and Port Douglas Area: the Quicksilver Group, Sailaway, Passions of Paradise, Ocean Free and Ocean Freedom, and Wavelength Reef Cruises.

Plant Coral Fragments

In June 2019, the Proof of Concept stage saw these operators, under Professor Sugget and his team’s guidance and supervision, start out planting coral fragments onto the reef structure at some of their sites on the Great Barrier Reef.

Even if Passions of Paradise had to cease its daily tourism operations since March 22, 2020, Alan Walish, the Founder and Managing Director, has donated the vessel to continue the Coral Nurture Program, to plant over 2000 coral fragments across two locations on Hastings Reef, named “Stepping Stones” and “1770”.

Alan says that Hastings Reef provides an excellent opportunity to acquire this program and put an intensive effort in enhancing the reef’s natural ability to heal itself. Hastings has encountered many challenges in the last decade, from the Cyclone Yasi in 200, the Crown-of-Thorns Starfish outbreak of 2012-2013, and the mass bleaching events of 2016, 2017, and 2020.

Initially, what concerned them most was the shutdown effect on the business; however, one thing that is good about this is the resilience of the reef locations. During the ten weeks of the shutdown, the crew has used this to plant about 1500 coral fragments. This has resulted in continual signs of natural improvement every year.

Coral Fragmentation

The Coral Nurture Program has the core in the process of coral fragmentation. While many people are familiar with budding, the asexual result of individual coral polyps cloning themselves to build colonies, and spawning, the sexual method of reproduction corals use. Many are unaware that corals have the third method of reproduction called fragmentation.

Russel Hosp, the Environmental Manager and Master Reef Guide of Passions of Paradise, explained the process. Most of the general public assumes that if the large coral structure is damaged, either by breakage from wildlife, severe weather, or other impacts, the entire coral colony will die. But this is not the case. In fact, the coral colony can recover quickly from pieces being broken off because of its remarkable regenerative ability.

For example, if the staghorn coral is broken off, the main colony, currents, tides, and other natural phenomena can carry those fragments across the reef. Suppose these get stuck in a particular area where it cannot move. In that case, the corals in the fragments will start to excrete extra calcium carbonate – the building material of hard corals and secure themselves into that location. They can grow an entirely new colony.

Use of Coral Clip

Russel and his team, including Marine Biologist Kirsty Whitman, have used the shutdown to use the coral clip to affix occurring coral fragments to the reef structure naturally. This unique process can plant the coral fragments quite quickly.

Since the March 22 shutdown, Passions of Paradise has been able to undertake four coral planting trips, and the crew has been able to so far plant about 1500 coral pieces in total. This is a great start for the environment at Hastings Reef.

According to Alan, they have always had a strong partnership with different scientific projects and organisations. They have hosted scientists specialising in corals, invertebrates, and sharks and rays. They ensure that they are going to continue this program until they can retake the passengers. Their goal is planting 2000 coral fragments; if they can achieve that, they will try for more.

Maintaining and Adding Six Coral Nurseries

During the shutdown, the focus work for the crew at Passions is planting corals on the reef itself. However, another aspect that kept the crew busy is maintaining and adding six coral nurseries, located at 1770. Scott Garden, the CEO of Passions of Paradise, believe that these nurseries are the major part of the Coral Nurture Project.

Scott explains that finding coral fragments during a dive can be pretty easy to extremely difficult. The idea of having nurseries is that they can attach some coral fragments they find to these underwater nurseries. The nurseries are large aluminium lattice frames, about the size of a household door.

As the program permits, as the corals are grown, they can break the fragments off from their nursery and attach them to the reef structure. This process is similar to the way a gardener will take plant cuttings, help them mature, and place the new plants in other areas.

The nurseries are not only beneficial to the crew in creating stocks or coral to transplant to the reef but also serve as a piece of exciting information to share with guests. Introductory and certified divers can dive near the frames and permit the crew to share this with guests.

Russel added that this had been a real shift over the last decade, as visitors to the reef will expect not only a five-star experience but also an authentic encounter with a high standard operator. This company shows a commitment to the conservation of the reef ecosystem. They believe that sustainability is not just window dressing, but they want guests to know they walk when it comes to conservation and sustainability.

As the Australian government slowly eases the COVID-19 restrictions, the company hopes that the day trips continue to succeed while continuing to plant coral fragments and monitor their nurseries. Alan said that the Great Barrier Reef is many things to many people, most especially to Australians. Their commitment is to conserve and give mother nature a say in everything they do.
