Facilities for scientists at the Nouragues station - Inselberg and Saut-Parare camps
Any kind of specific experiment should be beforehand indicated to the camp manager to be sure that required material is present on the camp, or that it’s possible to carry out it on the site.
A naturalist’ library is available, which contains not only reference books in tropical ecology, but also the PhD dissertations involving work at the Station.
A laboratory space is available. For any scientific experiment at the site, you may contact the station to check whether the equipment needed is already available. Laptop computers are onsite, as well as balances and microscope. Climbing gear, GPS, twins ninocular are also available. A drying oven is also functional for herbarium.
Data on rainfall and temperature have been taken manually since 1987. Data-capture is automatic since 1999. Humidity of soil surface is measured since november 2006. Recently, sites were fitted of environmental sensors for micrometeorology.
A system of grid trails has been set up in two areas around the camp: in the areas called ’grand plateau’ and ’petit plateau’ the grid trail is established every 100 m, materializing 1 ha forest plots, totalling over 100 ha of forest. Other permanent trails are maintained for instance to go to the top of the inselberg, or to reach remote areas.
A trail system has been established and a map of the area is also available for Saut-Pararé.
On the ‘Grand Plateau’, 14 000 trees are tagged and monitored for more than 20 years.
Over more than 70 ha, trees over 30 cm dbh were mapped, measured, and tagged once in 1992-94. In two plots of 10 ha (in grand plateau) and 12 ha (in petit plateau), trees over 10 cm were censused twice in 1992-94, then in 2000-02. Taxonomic identifications are somewhat heterogeneous, depending on the hectares and on the groups.
At Saut-Pararé, permanent tree plots were set up at the time of a project led by Museum National d’Histoire Naturelle. In on 6-ha plot, trees over 10 cm dbh were located, tagged and measured thrice, in 1985 and 1995 and 2007.
Since 2001, plant phenology has been followed permanently through a network of 160 permanent seed and litter traps. These traps are collected twice monthly and seeds are sent to the Brunoy Museum laboratory for identification. In 2003, 370 seedling plots were set up nearby the seed traps to follow the plant regeneration dynamics. Plants marked along a trail (’phenology trail’) are checked monthly for the production of flowers or fruits.`
At Pararé site, 6ha of forest are monitored. Trees over 10 cm dbh are identified and monitored.
The COPAS project (Canopy Operating Permanent Acces System), set up at the Parare site, is a canopy-access system of a novel type. It is made of three 45-m tall towers 180 m apart and covering an area of ca 1.5 ha. Towers are connected by cables above the canopy. The displacement of the operator is automatised. The system was inaugurated on September 20th, 2014.
La rivière Arataye peut être explorée en canoë depuis l’embouchure de la rivière.
The Arataie River may be explored in canoes from the mouth of the river up to Saut-Pararé.
Access to services
The Nouragues station is located in the depths of the pristine forest, unplugged of any road network. It only can be reached by helicopter or power-drived dugout. This specific logistic is operated by CNRS Guyane.
Housing at the station is basic but comfortable and secure. Visitors are under the guidance of CNRS employees, who manage security and routine maintenance on the station.
Communications with outside are insured by satellite phone and internet. A shortwawe connection is available between camps.
