Understanding the diversity, population dynamics, and carbon dynamics
of trees and other plants in Amazonian Peru
The Tree Research Team, with headquarters in the city of Puerto Maldonado, is tasked with listing the tree (and liana) species to be found at each research site. Other than diversity, the team also aims to determine the density, size distribution, basal area, community structure, and carbon content of trees (using multiple 0.05 ha forest plots) and how these vary within and between sites. Tree census plots are placed in all the forest types identified at each site. With the information gathered by this team used as dependent variables, the other wildlife research teams (i.e. mammals, birds, amphibians, etc.) can better understand the patterns of change within and between sites with respect to their own taxonomic groups of interest.

Methods Used and Skills Taught
The methods and techniques that our volunteers and interns learn and implement under the leadership and supervision of our tree research coordinators, include botanical plot set-up; diametre breast height (DBH) measurements of trees; tree species identification; tagging trees with numbered aluminium tags; and tree height calculation. Data analysis and visualisation programs that we use include R, SPSS, Estimates, and QGIS. Each field site requires 30-60 tree plots (each 10 x 50 m or 0.05 ha).

A Typical Day
Research days are split into morning and afternoon sessions. On each research day, typically both sessions are completed, for a total of around 7 hrs of active field time and data input per day. On most morning sessions, sampling begins at 8:00 am, after breakfast, with assessing the map of forest types at the field site and identifying the two or three plots that will be sampled that day. Having arrived at the geographic centre of the first plot, with the help of a GPS, a 50 m tape measure is used to mark out the centreline of the plot. With the help of a shorter 5 m tape measure, the team will determine if a tree is located within the plot or not. For those deemed within, a DBH tape measure is used to measure its diameter. Those trees within the plot and of a diameter of at least 10 cm, are subsequently identified, with voucher specimens taken if field identification is not possible. Photos of leaves, flowers, and trunk are also taken to aid identification is some circumstances. The presence of Guadua bamboo in a plot is also noted. In the morning session between 1-2 plots can be finished. In the afternoon, after lunch, one plot is usually sampled, with the remainder of the session set aside for data input and discussions of tree identification techniques. All research schedules and activities are subject to change at the discretion of the team coordinator.
