Mangrove Mania!!!

Mangrove Mania!

It was Monday afternoon at the beginning of lunch when I saw the volunteers troop in from the Mangroves; dirty, sweaty and exhausted. Panic struck me when I started to realized how hard maintaining the nursery must be. It was 1.55pm when I prepared myself for an absolutely draining activity and slowly made my way down to the nursery. How wrong was I! Although two and a half hours seemed like 24 hours of laborious weeding – the activity itself was quite enjoyable, especially with the people we were working with. 2016 chart music was blasted from the boys’ phones and the weirdest and most wonderful conversations took place. Either way we all ended up in hysterics.

Even though I hadn’t been scheduled into the environment workshop yet, seeing as there was an obvious equal divide on the project focused on diving and mangroves it didn’t take much time for anyone to realize that Mangroves had a massive impact on the conservation of sharks. This was slightly embarrassing seeing how quite a big majority of the world’s population think they know all about protecting marine life – they really didn’t!

My next activity involving mangroves was collecting propagules (mangrove seeds) and rubbish on the beach in Sulu’s and our Projects Abroad t-shirts which did bring a huge sense of pride knowing we were helping out the community. Our work was definitely greatly appreciated by the locals as we walked up the beach while they happily beamed out “Bula! Vinaka!” In this heat the job at first was quite hard at first since I couldn’t identify the propagules; after getting really excited that I finally found one but then realizing it was dead was a massive let down. After an hour or so on the beach I was extremely happy with my big black bag breaking from the weight of propagules I had picked up. We then trekked into the humid forest towered over by multiple types of trees, being me; the first thing that clouded my mind was spiders. A standard phobia but after hearing stories about how big they are here it caused me to be a lot more alert.

We hopped over barbed wire and pushed through bushes finding piles and piles of propagules, it got to the point where phobias had fled my mind and my main worry was if my bag was going to break as I started having trouble carrying the hundreds of seeds. It was fascinating watching our leader, a local Fijian, rip through the bushes and trees with a machete. I’ve never seen this before and I’m so used to the lazy 1^st world countries using electricity to do everything for them. During the collection I saw fully grown mangroves, in the flesh you realise the structure, strength and rigidity of them and it then made perfect sense as to how they protect the village and marine life against natural disasters.

My most recent activity involving the mangroves was a full day of weeding by the whole team; volunteers and staff. We all put 110% effort in to make sure the nursery was weed-free and all the mangroves were happy and healthy. It was brilliant to see everyone enjoying themselves although the heat was powerful the music was booming and sun was shining. After a very satisfied feeling of ripping the weeds from the soil and getting covered in head to toe with mud the nursery was in a great condition, knowing that the mangroves would be a home for juvenile marines species or protect a village from potential natural disasters.

Mangrove Monday!!

When I first arrived on the Shark Conservation Project, I was a little skeptical about the connection between mangroves and the survival of the shark population; however after taking part in the eye-opening environmental workshop the link was made clear.

Mangroves are carbon sinks, better carbon stores per square km than rainforests, the storage of carbon helps prevent the increasing effect of global warming. As the earth’s temperature increases, so does the ocean temperature, when this happens quickly corals can’t adapt to the changing conditions and consequently die. Many prey species for sharks live around these coral structures, so without them the shark’s food supply reduces. Mangroves also provide perfect nurseries for juvenile sharks to live in until they are strong enough to survive in the open ocean. Around Fiji there are known shark nurseries in large rivers like the Rewa and Navua, these are both surrounded by mangroves. But there are also shark nurseries which have not yet discovered so it is important to conserve all mangrove environments to ensure these nurseries aren’t unknowingly destroyed.

After being inspired by the workshop, it was not hard to get stuck into working in the onsite mangrove nursery at Projects Abroad, which is the largest in the South Pacific. My first experience in the mangrove nursery was planting propagules. Recycled plastic bottles are cut in half and used as plant pots, this is a small thing which helps prevent plastic entering the ocean. The team of 8 I was a part of worked like a machine and we planted the majority of the propagules we had in one morning. The job was swiftly finished by other volunteers in the afternoon.

As a result of the hard work, the propagule store needed to be replenished, so when out on the beach cleanup that week, it wasn’t just plastic we were picking up but also propagules that had been washed up onto the beach. We left the beach with 2 full sacks ready to be planted.

However it’s not just planting in the nursery that needs to occur to conserve the mangroves, once they have grown to a substantial size and have started growing leaves they can be harvested and planted in the community. We were given a target of 1100 propagules to harvest and tie into bundles of 10. This seemed like an unachievable target in one afternoon; however it was quickly reached by the group of tireless volunteers. These propagules were then taken to a local village and planted, hopefully in a few years they will still be growing into adult mangrove trees.

1100 propagules had been removed from the nursery, so 1100 more propagules had to be planted to replace them. The beach cleanup had provided the propagules, and the volunteers provided the man power to plant them. Again the team worked well together, replacing all the propagules that had been harvested and planting most of the propagules that had been collected.

In order to give the propagules the best chance of survival in the nursery, they need to be regularly weeded and watered. Weeding was surprisingly therapeutic and by the end of the session there wasn’t a weed in sight, so hopefully soon these propagules will have matured enough so they too can be harvested and planted in the community.

I have grown to love working in the mangrove nursery, it is hard not to feel a sense of achievement when we plant all the propagules, or when you see them growing successfully. Projects Abroad are hoping to extend the nursery on sight, and the one at the local resort Uprising in order to try and make the resort carbon neutral. I am proud to be part of the work towards a bigger, healthier mangrove habitat in Fiji.
