The one week expedition is based in the Iwokrama reserve, where students will spend their week based in one of the forest field camps. During this week the teams will complete training and surveys including:
In addition to the above the students will spend the week completing a Guiana Shield forest ecology course comprising lectures on Guiana Shield geography and structure, survey methods and how the data are used to describe community structure of key taxa, examples of species likely to be encountered and how Reduced Impact Logging is carried out.
The Iwokrama forests on the Guiana Shield in Guyana cover 1 million acres of mainly pristine lowland rainforest, these have been handed by the Guyanese government to the Commonwealth Secretariat to manage as a demonstration site, in a way that protects both biodiversity and develops income for local communities. The first attempt to develop such a strategy was the idea of using the site for ecotourism to sustainably produce income. However, this failed to attract sufficient numbers to what is a very remote area. The decision was made to develop a limited logging programme in such a way that it had minimal impact on the spectacular wildlife of these forests. Half of the Iwokrama Forest was set aside as a Wilderness Preserve where no activities or extraction is allowed. The remaining forest is the Sustainable Utilsation Area of which part is set aside for selective timber harvesting on a 60-year rotation. The area that is set aside for logging makes up only 29 percent of the entire Iwokrama Forest. The thesis that the foresters started with was that only a handful of the species have any commercial value and that only these would be targeted. Detailed maps are prepared of each 1km x 1km block of forest showing the position of each of the trees to be targeted and where the skid trails should be installed to minimize any losses of other species. The net result is that only 1% of trees (5% by volume) in any block are being harvested or damaged by the extraction process. This harvesting seems to produce as much return on investment as traditional harvesting techniques which are considerably more damaging, but does this new approach also minimise impacts on wildlife? The Opwall teams are helping scientists to compare the biodiversity value of a range of taxa in sites that have been recently logged, logged some years previously and pristine wilderness areas.
In 2020 we are starting with provision of help to a research programme in the South Rupununi centred around the Dadanawa Ranch. At one point, Dadanawa was one of the single largest ranches in the world, and it is still an active cattle ranch today. Initial research efforts include surveys on Giant Anteaters, as well as birds of the savannah (including the endangered Red Siskin). This new site will also serve as the hub for surveys up the Rupununi River into the recently protected Kanuku Mountains, with survey work focused on bats, herpetofauna, mammals and birds. To date, very little formal survey work has been done in the region, so the Opwall teams will be gathering valuable baseline data that can help inform the management of the Kanukus, as well as provide valuable contrasts to surveys in the Iwokrama forests of the North Rupununi.
The costs of a school group expedition can be highly variable. There is a standard fee paid to Opwall for all expeditions but the location you are flying from, the size of your group, and how you wish to pay all impact the overall cost.
You can choose to book the expedition as a package (which includes your international flights) or you can organise your travel yourself and just pay us for the expedition related elements.
If you are booking your expedition as a package, you also have the option of being invoiced as a group, or on an individual basis.
Each survey camp is different, with some being very basic and without any permanent structures, and with others being more developed. About half the site have long drop toilets and bucket showers set up near the river, and the other half have outdoor showers and flushing toilets. Accommodation at all survey camps is in hammocks with mosquito nets and bashas, which are small tarpaulins. For the start and end of the project at the Ecolodge, accommodation is in simple dormitory-style housing, with showers and flushing toilets. As the particular survey camp order is only finalised a couple of months prior to the expedition, we can give an indication of where you may be going during the training presentation in March.
The weather is generally hot, humid, and rainy for most of the field season. Daytime temperatures averages around 30, with at least some rain common most days. Being in the rainforest during the wet season, you will get wet!
