2. Project Coordinator Update
Tina Cormier, MS
W inter has finally arrived on Cape Cod! After some mild temperatures, we seem to be experiencing a
bit more typical weather here now. For many of us this time after the holidays is a great opportunity
to spend quality hours getting work done at the office. Our travel schedules are less hectic, and everyone
seems to be hunkered down at their desks, toiling away on research, reports, and proposals.
I am no exception! I have been working on several projects focused on the tropics and also in the U.S. I
am using field-collected reference data and radar, and optical satellite images to classify floodplain land
cover in the Varzea region of Brazil as well as along the Napo River on the Peru/Ecuador border. One of
the image stacks has 29 layers, with Landsat data reaching way back to the 1980s and ALOS data from as
recently as early 2011. It’s quite an impressive catalog of information, and we are excited to be mining it!
We are using the same segmentation–random forest approach that we have discussed in our workshops
to classify the images. Additionally, I have been helping Drs. Kellndorfer and Walker with a book chapter
detailing a radar-based land cover change analysis on a section of the Xingu River watershed in Mato Grosso, Brazil.
Dr. Kellndorfer and I are also working on a different type of radar project. We are trying to map soil moisture at two sites in the U.S. using
ALOS. We have field sites in Maine (forested) and North Dakota (agricultural) where we collect soil moisture information every 30 minutes
during the growing season, and we are trying to find a relationship between soil moisture and radar backscatter that would allow us to
generate maps of soil moisture in similar areas. Based on preliminary results, we will attempt to use modeling to remove the vegetation
response from the radar backscatter to get a clearer picture of how soil moisture is affecting the signal. We are also investigating the use of
C-Band radar (ENVISAT, RADARSAT). These projects have kept me very busy over the past couple of months!

Scholar’s Editorial from Gabon
Andréana Paola Mekui Biyogo, PhD
D ear Scholars,
It is so valuable to know each other’s activities and especially to understand what our evolution is in the
fight against deforestation and forest degradation in our respective countries and in accordance with the
training we have received at WHRC. As citizens of tropical countries we contribute to the slowing down of
forest loss for three forest basins – the Amazon, Congo and South-East Asia.
But what is our status in our individual countries? Is our expertise recognized there? In other words, how
can we measure the impact of the scholar program on our own countries? While some of us have decision-
making ability and autonomy in our work, it is not the case for others. For all of us, this newsletter can serve
as a platform to speak about and be heard on all the challenges we face in our work.
In this second edition, the activities undertaken by the scholars focused on the themes of CDM, REDD,
sustainable development, and climate change. While some of us are developing indicators of biodiversity (Mexico), others are concentrating
on field data collection protocols (Zambia), performing sensitivity analyses for an oil-rich forest reserve (Uganda), analyzing satellite data to
produce maps of deforestation (Bolivia), participating in workshops and contributing knowledge and expertise to national conversations
regarding deforestation (Gabon), completing REDD feasibility studies (Laos), or developing MRV methodologies on carbon (Indonesia). It is
inspiring to see how, in our own individual ways, we are all working toward a common goal!

6. Development and Testing of a Carbon MRV Methodology and Monitoring Plan in Indonesia
Virni Budi Arifanti
I am just back from the field in the Katingan District of Central Kalimantan Province. The Ministry of Forestry (MOF),
Republic of Indonesia, in collaboration with ITTO and Marubeni Corp has signed an MoU to conduct a full Feasibility
Study (FS) to develop a complete REDD+ MRV Methodology for the bilateral offset scheme.
One of the activities carried out by the MOF is to undertake, design, and test the applicability and scientific thoroughness
of the carbon MRV methodology through the measurement and monitoring of peat, water level, and forest biomass at
each permanent sampling plot. This work is jointly implemented by PT Starling Resources and University of Hokkaido
with the following activities:
• Forest Biomass (Above Ground Carbon stock) measurement: Analyze above ground biomass using remote sensing
technologies (e.g., ALOS AVNIR, Landsat) and field measurements, determine and establish Permanent Sampling
Plots (PSPs), develop allometric equation for peat forest.
• Peat analysis: Analyze peat depth data from past survey, determine and establish PSPs, analyze carbon content of
peat samples
• Water level: Set up data loggers at water level sampling plots, measure and test peat depth in selected PSPs, analyze
water level data at selected PSPs.

8. Remote Sensing Technology for
Conservation Monitoring in Uganda
Edward Senyonjo
I have been involved with a lot of satellite image analysis, vector
data analysis and fieldwork since my visit to WHRC. I am proud
to report that skills acquired from the WHRC pantropical program
came in handy as I worked through this congested schedule. For
example, I used Spring 5.1.6 for all image segmentation, ArcGIS 10
to process the vector data, and GPicSync for georeferencing field
photos and uploading them to Google Earth. The skills I learned
were not limited to remote sensing/GIS, but also included personal
and team building skills – gained from Alan and Ned, which helped
me effectively coordinate tasks with both management in office
and teams in the field. Indeed the team building skills are useful
in situations where we are working on projects with overlapping
time lines, limited resources, tight deadlines and high expectations
from policymakers.
l was responsible for the production of forest maps and other
information from Landsat satellite images for the Maramagambo
forest reserve. We used this information and maps to create
sampling designs for tree species distribution and biodiversity
surveys which targeted birds and mammals. Maramagambo
forest reserve is one of the largest, least surveyed forest blocks
in Uganda. It is part of a complex forest ecosystem that lies in an
ecologically sensitive area better known as the Albertine Graben,
which is very rich in biodiversity. This is located in southwestern

9. REDD Feasibility Study for the NEPL NPA in Laos
Akchousanh Rasphone & Colin Moore
T he end of 2011 saw The Wildlife Conservation Society complete a REDD feasibility study for the Nam Et Phou Louey
National Protected Area (NEPL NPA) in Laos. To do this, land cover change maps (Figure 1) for four years (2000, 2004,
2006 and 2010) as well as a current land cover map of the NPA (Figure 2) were produced using Landsat imagery. These
maps allowed us to understand what the current carbon stocks were, on site, and to calculate rates of deforestation.
Despite knowing that agricultural practices in the NEPL NPA are intensifying and expanding, our analysis demonstrated
that historical rates of deforestation in the NPA have traditionally been low. This is because the expansion is occurring in
existing fallow areas rather than at the expense of forest. This means however, that the project has a low emission reduction
potential, based upon current methodologies accepted by the Verified Carbon Standard, and is unlikely to generate a high
number of carbon credits.
The outcome is that WCS is now looking into alternative approaches to develop the NEPL NPA as a REDD project. In
particular, WCS is exploring the possibility of developing a sub-national, jurisdictionally based REDD project into which
the NEPL NPA would ‘nest.’ Jurisdictional-based REDD is the direction REDD is taking under the UNFCCC. By supporting the
development of REDD in NEPL NPA along these lines, WCS hopes to be at the cutting edge of REDD developments.

Africa; and we also work globally, focussing on how humans are changing global cycles of carbon,
nitrogen, and water. We merge natural science with economics to discover sustainable paths for
human prosperity and stewardship of the Earth’s natural resources.
Our mission is to advance scientific discovery and seek science-based solutions for the world’s
environmental and economic challenges through research and education on forests, soils, air,
