A big welcome to our latest group of volunteers. They joined us 2 weeks ago from a variety of nations and we look forward to a successful phase 123. Since their arrival life has been as fast and furious as ever and here are just a few things that have happened in this short space of time:
Not only do GVI staff and volunteers spend hours comprehensively sweeping forest trails and canals in Tortuguero National Park, we also live deep inside the parks southern boundary. Our 24-hour presence either on base or travelling to town establishes a constant connection between us and unbelievably diverse ecosystems. Many of the species we see are ever present in our temporary home. Clay coloured robins Turdus grayi frolicking around our ‘garden’, American crocodiles Crocodylus acutus basking at the river mouth and mantled howler monkeys Allouata palliata alerting the world to the rising sun with a roar that would not be out of place in ‘Jurassic Park’. These animals all have one thing in common; Tortuguero National Park (TNP) falls within their normal distribution and they are abundant here. This does not mean that is not important to record their continued local existence as a change in abundance may signify significant alteration to the parks habitats. However, to record a species that is believed to be rare within the park or that has a normal range not believed to overlap with TNP, really does instil a great deal of excitement and brings home the fact that our research station can add new data to worldwide species databases. And we are in the process of building up a collection of such sightings.
Birds are an obvious contender for such recordings. Although they may have specific distributions mapped in scientific literature, their ability to transcend boundaries through flight enables them to migrate to locations their may have rarely frequented before; a situation which will likely become more prevalent as the effects of climate change begin to take their toll. So what have we seen here that we apparently shouldn’t have been so lucky to do so? Here is a few we have accumulated in 2012:
But it is not just birds of note that we have recorded; there is also a snake that stands out. To me it resembles a mini anaconda (a species I would give my left arm to see in the wild) and one that is also believed to be very rare in this area. It wasn’t discovered on any of the trails or along the waterways but under the staff house! Again illustrating how we can make a contribution to the scientific community by merely taking a few steps from our beds. I give you the orange bellied swamp snake Tretanorhinus nigroluteus!!
So what are we doing with this data? Firstly, all the data we collect goes directly to MINAET, who will hopefully be able to incorporate it into the park’s new management plan. We also report any rare bird sightings directly to Asociación Ornitológica de Costa Rica (AOCR). And finally, GVI we have begun to collaborate with I-naturalist and an official GVI Tortuguero project has been set up. I-naturalist is a worldwide database that allows experts and amateurs alike to upload photos of species they have seen all over the world; thus documenting a current and accurate distribution of all species in time and space. We are currently developing an extensive photo database of every species we have photographed in this area and aim to upload these to our project on i-naturalist on a regular basis.
The work GVI has accomplished studying jaguars in Tortuguero National Park has started to catch the attention of feline biologists and conservation organizations. Since moving to the Jalova field station in 2010 the frequency of jaguar captures on camera has steadily increased. Jaguars can be recognized and told apart by their unique rosette patterns on their fur, and to date GVI has identified 10 different individuals active in the 3 mile survey area. They have achieved this with over 500 nights of camera trapping and more than 1000 jaguar pictures collected and identified in their database. A scientific paper written by Diogo Verissimo, a previous GVI staff member, brought to the attention of the media and the scientific world the incredible and unique interactions between Jaguars and Marine Turtles on the Tortuguero beach. We believe this relationship is what is principally supporting the coexistence of such a large jaguar population in such a small area.
“Panthera was founded in 2006 with the singular mission of conserving the world’s 36 species of wild cats, it currently focuses its range-wide conservation strategies on the world’s largest, most imperilled cats, one of these being the jaguar, the largest cat in the Western Hemisphere”. The hard work of the GVI Costa Rica Expedition team has been repaid with the possibility of working alongside this leading organization. Roberto Salom-Perez, manager of Panthera’s Costa Rica jaguar projects, visited our Jalova base whilst working here with the BBC wildlife team back in September 2011. Nearly 8 months later, after a lot of paperwork and meetings the first signatures were laid on what will be a 3 year collaboration between Panthera and GVI.
Expectations are high on both sides. The GVI team will be helping Panthera field scientists as they try and explore the extent and distribution of the jaguar population in the whole of Tortuguero National Park. The small piece of the puzzle that we have been working on for the past two years may now fit into a larger framework that will help with the management and conservation of jaguars in Costa Rica. Expertise from the Panthera staff will help the GVI team come up with new methodologies and extend the GVI camera trapping project to cover a larger survey area. They will also provide the means to allow us to expand our study techniques to include scat collection and analysis, a development that could greatly aid our understanding of the local jaguar population.
Recent funds to the National Park helped in facilitating extra patrols during the high poaching and hunting period Semana Santa (Holy week before Easter). During this time there is higher demand for turtle products and also increased activity from hunters in the forest of the park, looking for deer and wild pigs.
Extra personnel were able to be drafted in to run the patrols through the means of police. This adds not only extra people but also more authoritative figures so further people can be detained for law breaking. Without the food money the police would not be able to stay in the park and thus be unavailable for patrol.
These funds meant that this Semana Santa period was one of the better patrolled of all time which is good news for the local wildlife. However poaching is still rife in the park and increased protection needs to be sought year round. Without the extra funds in the future this will not be facilitated and the future green season will see a larger strain on park ranger resources.
We would like to share the most recent trustee report from the GVI Charitable Trust. This report covers the six month period from July to December 2011.
We are delighted to share that this has been by far our most successful period, raising in six months nearly as much as we did the whole of the previous year. This increase in funding has brought a corresponding increase in the impact we have been able to create on our programs around the world.
During this period we have invested in sustainable education across Latin America including support for the elderly in Guatemala and income generation schemes to support education in Honduras and Ecuador. In Mexico we have worked with a community to establish a recycling centre and in Kenya our partners in Mombasa will now realise their goal of seeing impoverished students through to completion of the primary education earning recognised qualifications for the first time.
These are just a few highlights of an amazing, productive and rewarding six months. Thank you to everyone who has supported us and played a crucial role in these achievements.
