Quarter: 
July - September
Communications activities: 

Atila Cristina (vegetation protocol) participated in the workshop "Environmental Science in the Amazon: RAINFOR as a catalyst for integration of network projects, the data oriented analysis and production of articles" in the period 19-26 June, in Acre state (Brazil). The event involved the training of students in data analysis and scientific writing. This event is part of the international research program organized by the Federal University of Acre (UFAC), University of Leeds, England and the National Institute for Amazon Research (INPA)

New Species: 

Puma yaguarondi, recorded in two camera traps in the area of ​​ZF2.

Protocol Activities: 

Vegetation:

-In June: Participation in the RAINFOR workshop;
- In July:  placing pickets in six IMAS, organization of field sheets and purchase the material field for the census.
- In August:  the census was conducted in three IMAS (Ducke headquarters, Ipiranga and Km37- ZF3).

Climate:

Climate Protocol developed the following activities: collection of climatic variables (precipitation, air temperature, relative humidity, solar radiation, diffuse radiation, photosynthetic active radiation - PAR and soil moisture), maintenance of sensors, data tabulation, sending data to the TEAM database; data analysis and discussion with Vegetation and Litterfall protocols, development of monthly and annual climatologic  bulletins with our results.

Terrestrial Vertebrates:

Sampling began in 2011. We install and remove the cameras in the first set of cameras without any technical or logistical problem. We began sampling in the second set of cameras and this area had difficulties (fallen trees, dense vegetation in the ways of access, etc).

Protocol Problems: 

Climate:

Problems occurred in the sensors that measure radiation Par, diffuse and global. We did the cleaning of sensors and other equipment, however the problem was not resolved. It is a defect in the equipment itself, and this needs to be replaced.

Terrestrial Vertebrates:

1- The installation of cameras in "array 1” was very difficult because the access tracks made ​​in 2009 have many fallen trunks and other obstacles. The trails are hard to find, because rapid growth of vegetation during the rainy season.

2-  One camera has failed. Because the problem can not be resolved, this camera will not be used following the sampling. Extra cameras could not be used because it already had problems after used in site Caxiuanã. An immediate and temporary alternative was to borrow similar cameras from another project to be used in TEAM sampling.

Schedule Problems: 

Terrestrial Vertebrates;

The sequence of sampling in the second set of cameras had to be five days postponed because the fellow in charge of sampling was recovering from disease.

Suggestions: 

Climate:

An important point is with respect to variable wind direction and wind speed that is currently impaired by the vegetation around the station. This interference is already observed in the current protocol, because the automatic station - CR23X is installed in an area which is surrounded by vegetation with heights ranging from 10 to 35 m. Because of this natural barrier, the records of these two variables are affected. As a suggestion it would be interesting these two sensors be installed above the canopy allowing the registration of these variables more adequately, resulting also in a flexible time-series comparison with other experimental sites throughout the Amazon.
