The National Network for Long-Term Monitoring of Forest Ecosystems (RENECOFOR)

Since 1993, the USRAVE has realised the analyses of broad-leaved trees, conifer and litters for ICP-Forest Level 2 in France: RENECOFOR .

Since 1993, USRAVE has been conducting analyses of broadleaves, conifers, and litter for the RENECOFOR network.

RENECOFOR (National Network for Long-Term Monitoring of Forest Ecosystems) is a network of 102 plots distributed across mainland France.

The National Network for Long-Term Monitoring of Forest Ecosystems (RENECOFOR) is managed by the National Forest Office (ONF). Its goal is to carry out long-term (30 years) monitoring of forest ecosystems, which includes evaluating the nutritional status of trees.

This network consists of 102 plots. On each plot, leaf samples are collected. To collect leaves from the tops of trees, the use of a gun is necessary.

All physicochemical analyses of the leaf samples are carried out at the Unit for Plant and Environmental Analytical Services (USRAVE). These analyses include, among others:

  • Mass of 1000 needles
  • Content of mineral and organic matter
  • Total carbon and nitrogen content
  • Macronutrients: Phosphorus, Calcium, Magnesium, Sodium, Potassium
  • Micronutrients: Copper, Iron, Manganese, Zinc
  • Trace elements: Cadmium, Chromium, Nickel, Lead, Cobalt, Molybdenum
  • Aluminium content
  • Boron content
  • Sulfur content
  • Chloride content

The first sampling campaign began in 1993.
