Activities of the Protocols:
During this period we processed the material from plot YAN VG-05; that is, we separated the duplicates to send them to other herbaria as a gift or exchange, and we selected the specimens to be mounted in the HOXA Herbarium.
With the help of Jorge Ahumada, we uploaded the information from the 6 plots to the TEAM Web site. There were some typographical errors that we have resolved almost entirely. Only one difficulty remains in the YAN-VG-2011-06-26-NEW file, as described later in the report (Appendix, page 1).
Terrestrial Vertebrate Protocol:
We finished naming the photos of the two arrays and then placed them in two files, CT-YAN-2011.01-Array1-64.tpk and CT-YAN-2011.01-Array2-64.tpk. Because they are too heavy and would not fit on a single DVD, we recorded each file in a separate DVD and also made copies on a USB. A couple of weeks ago, we placed in the mail an envelope containing the 2 DVDs and USB, with the information from the camera traps, sending it to the address indicated in the protocol.
In March, we visited the site of the meteorological station with the local climate specialist and observed its functioning. Below is the technician’s report on the operation of the station:
1. Location of the meteorological station
The site was selected following the recommendations of the Team Network. (2010), which are based on the guidelines of the World Meteorological Organization (WMO, 2008) and the Environmental Protection Agency (EPA, 1995). The site is located in the Pampa de Pescado area at 10 ° 21 '59.80 "S and 69 ° 14' 41.39" W.
In order to meet the requirements of the solar radiation sensors and obtain reliable measurements of the incident and diffuse radiation, we prepared the site by removing some trees that blocked the visibility of the point selected for the meteorological tower at about 5 degrees elevation. Thus, the requirements of Level 1 Siting were fulfilled. First, we removed the weeds and shrubs from an 80 m2 area containing the point where the UT10 tower was to be installed. From the point selected for the tower, we calculated the distance to the nearest trees found in a range of 10 to 25 meters. We removed those tress that did not meet the requirement of being at a distance from the point of the UT10 tower of 4 times their own height and those that obstructed the horizon above 5 degrees elevation.
2. Preparations prior to the installation
After clearing and preparing the rectangular 80 m2 area, we installed a 1.5-meter high mesh perimeter fence to prevent entry by animals that could damage the meteorological instruments.
Following the protocol, we collected data from the location where the base of the UT10 tower is to be installed, including measurements of the angles and distances of the obstacles (see Appendix). We also took panoramic photographs of the site.
3. Assembly of the meteorological station
The UT10 tower and the sensors for solar radiation, temperature / relative humidity, and precipitation were installed according to the TEAM Network (2010) and the manuals of each of the instruments, as described briefly below.
3.1 Installation of the UT10 tower
Following the manual for the UT10 Weather Station, we prepared an area 65 x 65 cm square x 50 cm deep, filling the hole with cement and concrete to anchor the base of the tower and support the weight of the tower and sensors. In this concrete base we mounted anchor bolts, and in them we installed the base of the tower and the accessories required for the various sensors. In addition, we installed protective housing in which we placed the CR1000 datalogger.
3.2 Installation of the solar panel
The solar panel was installed at a height of 1.6 meters above ground facing north with an inclination of 10 degrees in order to maximize the impact of solar radiation.
4. Programming of the sensors and data recorders
Personnel from the site were not able to download the routine for programming the sensors of the Yanachaga-Chemillén site. We therefore proceeded to create a routine following the CR1000 Measurement and Control System operating manual. We established the program using the CR Basic Editor shortcut, taking into consideration the following characteristics in the TEAM 3.0 manual and videos. We will update the script with the official TEAM script next time the station is visited.

5. Assembly of the sensors in the UT10 tower
To assemble the sensors, we used the TEAM 3.0 operating manual and the manuals for each of the sensors. Details are below.
5.1 Vaisala HMP45C sensor for temperature / relative humidity
The two sensors were placed at a height of 2 meters above ground within the lower tube of the radiation shield and then placed under the umbrella of the radiation shield according to the corresponding layout for connecting cables. The cable connection to the CR1000 memory was made taking into consideration the details of the following figure, as well as the diagram of the corresponding manuals.

5.2 Licor200X solar radiation sensor
The two solar radiation sensors were installed at a height of 3 meters above ground, one facing north and the other south—orientations intended to take account of the changing path of the sun. To ensure that the sensors were properly leveled in the underlayment base (LI2003S), we used a spirit level and screws to mount them. The cables in the datalogger were connected taking into consideration the following figure and charts provided by TEAM.

5.3 TB4 Rain Gauge
The rain gauge was installed 6 meters from the base of the UT10 tower at a height of 30 cm above ground. The gauge was installed on the CM 240 frame, where it was leveled. The transmission cables to the datalogger were protected in PVC tubes. The three terminals of the cables in the datalogger were connected following the description in the figure below.

5.4 Installation of the manual rain gauge
The rain gauge was installed to provide a manual backup and to periodically verify the accuracy of data recorded during extreme precipitation events (> 50 mm / hour).
6. Testing of the operation of the station
The 12V DC-100 Ah (UB-121000, Universal Power Group) battery was installed inside a waterproof, impact-resistant plastic casing with sufficient ventilation. It was connected to the power stabilizer to prevent the load received by day from flowing into the solar panel at night. A pair of wires was connected to the CR1000 datalogger, and then the data were recorded, verifying the operation of the system, as shown in the figure below.

Problems in Implementing the Protocols:
In the file YAN-VG-2011-06-26-NEW, in the date field of the metadata sheet, we forgot to insert the day. I have tried several times to correct the problem and have been able to open the page and view and correct the problem. However, at the moment when the information is recorded, this correction is not saved and then the metadata sheet continues to show the error.
Terrestrial Vertebrate Protocol:
No problems except a slight difficulty in the mail, as described below
As indicated in the technical report, we were not able to download the TEAM routine for programming the sensors of the Yanachaga-Chemillén site. We worked with the helpdesk to obtain the script and it will be installed next time the station is visited.
No problems in this period
The envelope containing the discs and the USB with the information from the camera traps, which we mailed to Eric Fegraus, was detained at customs in Lima, and to allow it to leave Peru, we had to fill out a form that they sent to us. Apparently it is only a formality that we must follow, and we assume that the envelope containing the discs and USB will arrive soon.
