3.4.4 Threatened Trees Species Distribution
The aim of plant species distribution mapping is to identify species that threatened under IUCN List. Preliminary survey during the preparation of the
declaration of the national park that was conducted in 2005 by Fernando Santana, was implemented transect data record within three target protected areas such
Jaco, Paitchao-Tutuala and Lore Reserve. Survey was applied transect line by observing within radius 200 meters from estimated track line at three different
area, Jaco Tutuala and Lore. Data recorded is number of trees species that counted along the track line and stored as tabular format. Statistical data processing is
applied to identify dominants tree species, endangered, near threatened, threatened and red list species that must be considered as high values forest that would be
protected.

Note: Data in Paitchao, Jaco and Lore are numbers of frequency counted
Unfortunately data was recorded without geo-positions marking, and it’s difficult to plot into spatial distribution. Through this data processes discovered
the trends of trees that most frequent. Table and figure below are described IUCN protected plants species frequency counted by transect of Tutuala Forest, Jaco
Forest and Lore Forest. Appears that Tutuala Forest is the most high frequents of four protected species, while Jaco only recorded two protected species with less
number and Lore Forest with three protected species on IUCN Red List on Pterocarpus indicus, Intsia bijuga, Anthiaris toxicaria and no record for
Elaocarpaceae. The endemic Indonesia and Timor-Leste, Pterocarpus indicus is highly frequented and follow by Intsia bijuga.
