Corals will return to damaged reefs eventually, if all the ecological factors are present. However, when most are destroyed, regeneration can take as long as 50 years. She learned from Fijiguide.com’s visiting photographer, Scott Putnam, that live coral can be replanted. You simply take the broken pieces on the sea floor and place them into pukas on the reef. The idea originated in the aquarium trade, where broken small pieces of coral called “frags” are replanted on live rock.
The practice can yield to spectacular results in just a few years. A little planting can protect the corals from their predators and can go a long way in helping reefs rebound. More importantly scientists have recently discovered that corals send out chemical signals that indicate a particular area is safe to populate. Other species of corals will answer the call and migrate into the area.
Roberta decided, she didn’t have fifty years to wait for the reef to mend itself.
Immediately after learning the replanting drill, she logged about 200 free dives to make certain replanting actually worked in the wild. To her relief and it did. She has made thousands of free dives since then which consist of picking up coral fragments off the sea floor and planting them. She reports a 90 per cent survival rate for the coral fragments which “take-off like a shot within 4 weeks once they take root.” She’s also engaged the local population to get involved.Every Sunday, Roberta and a small group ofMakaira staff and teenage boys from the nearby village, plant coral fragments on the reef. Even resort guests have joined in.
With much enthusiasm he planted what is now magnificent little reef, which makes her smile every time she takes guests on a snorkel tour.
Guests who would like to indulge in reef gardening are greatly appreciated. Generally Roberta will go out with them and pick an area where they can plant their own section of reef. They mark their territory with a fair amount of colorful, blue staghorn acrophora corals. Upon their return, guests can see the stunning results. Blue-green Chromis occupy the burgeoning coral and the rest of the reef fish population is catching up. Once guests see the fruits of their labor, they immediately schedule time to plant more corals.
Like the transplanted coral, the 50-something Kalani High School grad and her Big Island husband have surely taken root in the Garden Island of Fiji.

That's not bad even for a home in Taveuni. It looks amazing!
Well, I could also find my home easily on the Fiji Islands but I would also need some utilities. A friend of mine found recently some cheap ones at Kirby. I'm also thinking about buying from there.
Good for her that she finally found her home, I'm looking for a nice house since last year and I still didn't find one for my taste. A friend of mine told me that I should check Visithphomes because I will surely find there what I'm looking for.
I would also like to find a nice house on the Fiji Islands, I already have a few alternatives, I just have to decide myself. The furniture would not be a problem, I heard that the best prices are on https://www.affordablestoragecabinets.com/.
I would also like to live on the Fiji Islands but I am afraid that I cannot afford to buy myself a house there. That is why I'm thinking about renting an apartment. I heard that I can find some nice apartments on https://4rentweekly.com/.
