Project Number: 6204-22000-019-10
Project Type: Specific Cooperative Agreement

Start Date: Mar 01, 2007
End Date: Jan 22, 2010

Objective:
The objectives of this cooperative research is to determine distribution and density of A. donax in the mid and lower Rio Grande Basin.

Approach:
Sites in the Rio Grande Basin will be visited by Pronatura staff to determine the density and distribution of A. donax. GPS coordinates will be taken above and below dams along the riparian zones which will be used to obtain Quickbird images. Arundo donax shows up in this images as a distinctive pink color which can the be translated on computer to hectares infested. The number of hectares infested can then be used to estimate the number of river miles infested with A. donax in the Rio Grande Basin.
