ARGENTINA INSTITUTIONAL FRAMEWORK OF THE MONTREAL PROCESS

  • Argentina endorsed the Santiago Declaration that resulted from the sixth meeting of the Montreal Process Working Group held in Santiago, Chile, in February 1995.

  • The Consulting Technical Committee is at the National Institute of Agricultural Technology (INTA), and the person in charge is Dr. Tomas Schlichter.

  • The Argentine institutions involved are the Secretariat of Agriculture, Livestock, Fisheries and Food (SAGPyA) and the Secretariat of Sustainable Development and Environmental Policy (SDSyPA).

First National Inventory of Forest Plantations and Management of a Related Database

The Consortium formed by Aeroterra (Argentina), Tecsult International Limitee and Simons Red Collins (Canada), was in charge of the inventory according to procedures determined by the contract.

It began during December 1997 and ends August 2001.

Indicator 7.4B - SCOPE, FREQUENCY AND RELIABILITY OF FOREST INVENTORY

First National Inventory of Forest Plantations and Management of a Related Database

General objective

  • Define an economic, efficient and sistematic system to obtain data for forest plantations and execute the first inventory of forest plantations.


Slide11 l.jpg

Secretaría de Agricultura, Ganadería, Pesca y Alimentación

Indicator 7.4B - SCOPE, FREQUENCY AND RELIABILITY OF FOREST INVENTORY

First National Inventory of Forest Plantations and Management of a Related Database

Specific objectives

  • At the Province / region level:

  • Define areas of plantations (size, location) of all major species, Pinus spp; Eucalyptus spp; Populus and Salix spp; other conifers and hardwoods.

  • Estimate total wood volume for the main groups of species per province / region.

  • Produce thematic maps 1:100.000 scale - Infrastructure and forest polygons digitized and adjusted to satellite image Landsat TM5.

  • Store all the data in a Geographic Information System (GIS).

  • Establish a database for assisting in the updating of the inventory.

  • Training personnel in all the phases of the inventory.

Regions

There are plantations that are not included for different reasons in this inventory

  • Difficulties to determine the area of recent plantations with trees too small to be seen in the satellite images.

  • Detection of windbreaks.

  • Plantations smaller than 5 ha.

  • Plantations established after 1998.

Indicator 7.4B - SCOPE, FREQUENCY AND RELIABILITY OF FOREST INVENTORY

Error

  • < 10% for each of the 4 regions that contained most of the planted area.

The error associated with the estimation of the volume per unit area was:

  • < 15% for the other three regions where the rest of the plantations were located.

In both cases 95% of confidenciality

The area of the recently established plantations was underestimated because their trees were too small to be seen in the satellite images.

This problem was ameliorated by the fact that 90% of the area planted since 1995 has been registered in a Geographical Information System by SAGPyA.

Argentina forests and woodlands

The native forest area of Argentina is estimated around 36 million hectares, this means that about 13 percent of the country continental surface is forest and woodland and its potential commercial capacity is estimated in approximately 15 million hectares.

Due to the country extension, the areas covered by native forest are quite different among them. Therefore, they have been grouped in six forest native regions. They present a rich diversity of ecosystems varied in their floristic composition, structure and the fauna they support.

Espinal

This area includes very few relicts of original vegetation because of extensive agriculture activities and it does not have a significant native forests except conservation areas, but includes the most important man made forest in the country.

The principal forest species are: Prosopis caldenia, Prosopis nigra, Prosopis algarobilla, etc. Estimated surface is 4.000.000 hectares.
