ImazonGEO Tool: Legality Map

The Forest Legality Alliance partnered with Imazon, the Amazon Institute of People and the Environment, to build on ImazonGEO, a map server tool that provides map-based information about the Brazilian Amazon.

Specifically, FLA supported the addition of legality and supply chain data for the Brazilian States of Parà to the map server.  The “legality” section of the map server allows users to select from a list of exporting companies and locate the geographic origin of the wood on the map.  Information available includes:

  • Publicly available information regarding the forest management authorizations by exporting companies; information includes period of validity of the harvesting, authorized volume and area, logged area, species authorized for harvesting, HTS code, and departure, intermediary and arrival ports;
  • Geographic data showing areas under forest management plans and areas of authorized and non-authorized logging (from 2007 to 2011);
  • IMAZON’s evaluation of forest management practices within each permit area based on remote sensing image observation using the Normalized Difference Fraction Index*, supplemented with field observation, and
  • Location of ports along with commonly shipped commodities and destination in the United States.

How to Use the Legality Section of the ImazonGEO Mapping Tool

  • To get to the legality information, click on “Legality” under the “Timber Harvesting” tab. 

            

 

  • Once there, you can choose the exporter and permit of interest to view the areas of authorized and unauthorized logging (see example for 2008) on the map. Click on “show area” to execute selection.

            

 

  • Click on the “R” red balloon   for a pop-up box of information on the particular authorization permit, such as the period of validity, authorized volume and area, HTS code, and departure, intermediary and arrival ports.  The permit information box also provides information on IMAZON’s assessment of the forest management practices in the permit area, listed as “quality of timber harvesting” . Click on the PDF icon next to the authorization number to get all available information about the authorization, including list of species logged.

​            

 

  • Click on the “L” red balloon   for a pop-up box of information on the area authorized for logging in 2009, including size of the area logged and location coordinates.

            

                                

                Good quality forest management                              Low quality forest management

                                                           

 

  • Click on the “P” red balloon  for a pop-up box of information on the port, including intermediary ports and port of arrival, commonly traded commodities from the port, HTS codes, a link to the port’s website, and a photo of the port. If the ports are not immediately visible, you may need to zoom out.

            

 

  • Additionally, the “Timber Harvest” tab of the map server also provides a number of Imazon’s “Transparency in Forest Management” bulletins in English and Portuguese that provides quantitative data from 2006- 2011 on forest management and protected areas in the State of Mato Grosso and Pará. The bulletins are available for download in PDF.

           

 

*  The Normalized Difference Fraction Index (NDFI) enhances visuals of selective logging, which can be seen from disconnected linear features indicating logging roads and canopy damage scars highlighted by yellow to orange colors. Forest management quality  is evaluated using NDFI images and determined thresholds for quality: NDFI ≤ 0.84 represents low quality (predatory logging); NDFI= 0.85-0.89 for intermediate quality (indicating attempt at adopting management but insufficient for proper execution of management plan); and NDFI ≥ 0.90 for good quality (meaning that the layout of roads, log landings and clearings is in conformity with accepted forest management techniques).
