Glossary
Common name Refers to the adopted name of a species as is widely used in the country;
may be based on English or other foreign name, or Tagalog name, or
when no local or vernacular name is available is derived from the
meaning of its scientific name.
Critically Endangered When used in the context of the IUCN Red List, a taxon is classified as
(CR) ‘Critically Endangered’ when there is an extremely high risk of extinction
in the wild in the immediate future (IUCN, 2001).
Endangered (EN) When used in the context of the IUCN Red List, a taxon is classified as
‘Endangered’ when there is very high risk of extinction in the wild in the
immediate future (IUCN, 2001).
Forest lands Include the public forest, the permanent forest or forest reserves, and
forest reservations.
Forests Land spanning more than 0.5 hectares with trees higher than 5 meters and
a canopy cover of more than 10 percent, or trees able to reach these
thresholds in situ. It does not include land that is predominantly under
agricultural or urban land use.
IUCN Red List of The IUCN Red List of Threatened Species is the world's most
Threatened Species comprehensive inventory of the global conservation status of plant and
animal species. It uses a set of quantitative criteria to evaluate the
extinction risk of thousands of species. These criteria are relevant to most
species and all regions of the world. With its strong scientific base, The
IUCN Red List is recognized as the most authoritative guide to the status
of biological diversity.
IV
Glossary
Lesser-used species Also called Lesser-Known Species, are species that are commercially less
accepted species left in the forest after a logging operation. These are
species that are not being put to best advantage (although many
commercial species are not being put to best advantage either).
Native trees Trees that are living, growing, and reproducing naturally in a particular
region. The focus in using native trees should be on trees that are native to
the region and that are well-adapted to the specific site where they will be
planted.
Premium Species Refers to tree species, the wood of which has special characteristics such as
strength, durability, beauty, scarcity or rarity, or is used for special
purposes, and included in the list of such species embodied in DAO No. 78,
Series of 1987 and other species that may hereafter be classified as such.
Secondary forest A rainforest that has been disturbed in some way, naturally or unnaturally,
created in a number of ways, from degraded forest recovering from
selective logging, to areas cleared by slash-and-burn agriculture that have
been reclaimed by forest. It is characterized (depending on its level of
degradation) by a less developed canopy structure, smaller trees, and less
diversity. Due to the lack of a full canopy, more light will reach the floor,
supporting vigorous ground vegetation. "Jungle" is the term often applied
to secondary forest with dense ground growth, but it is also applied to
some tropical moist forests where seasonal variations permit thick ground
growth.
Tropical This forest type is characterized by little or no seasonal water shortage and
Evergreen Lowland rather uniform warm and humid conditions. It is structurally complex
Forest showing multiple layers along its vertical length. Scientists recognize 3 to 4
vegetative or structural layers each of which constitutes habitat for a tightly
packed community of vertebrate and invertebrates
Undergrowth Low growth on the floor of a forest including seedlings and saplings,
species shrubs, and herbs
Vulnerable (VU) When used in the context of the IUCN Red List, a taxon is classified as
‘Vulnerable’ when facing a high risk of extinction in the wild in the
immediate future (IUCN, 2001). Refers to a species or subspecies that is not
critically endangered nor endangered but is under threat from adverse
factors throughout its range and is likely to move to the endangered
category in the future (DAO No. 2007-01).
Watershed An area of land that feeds water to a river, draining through the landscape
into tributaries and main river channels. Also called catchments, drainage
basins or river basins.
Wood The hard-fibrous substance consisting basically of xylem that makes up the
greater part of the stems, branches, and roots of trees or shrubs beneath the
bark and is found to a limited extent in herbaceous plants

Message
Forests give us life. Not only does it give us essential products, like food and medicines, but
forests also provide critical ecosystem services, like water catchment and air purification.
Forests are also home to diverse plants and animals, including indigenous peoples. Without
forests, we clearly won’t survive. In the last decades, however, there has been a steady
decline in the Philippine forests. From the original 27 million hectares of forest cover, it has
decreased to 7.3 million hectares in 2015.
In 2002, under two bilateral agreements between the governments of the United States of
America and the Philippines, the Forest Foundation Philippines, formerly known as
Philippine Tropical Forest Conservation Foundation, was established to provide grants to
organizations that empower the people to protect the forests. The Foundation currently
focuses its support to the landscapes of Palawan, Samar and Leyte, Bukidnon and Misamis
Oriental, and the backbone of Luzon, Sierra Madre.
Sierra Madre, the longest mountain range in the Philippines, runs from the provinces of
Cagayan in the north to Quezon in the south. It has a land area of approximately 1.4 million
hectares, which is embraced by ten provinces, including Quirino. Out of the 22% forest cover
left in the country, 40% of which can be found in the Sierra Madre. It provides habitat for
growth and development of diverse flora and fauna, which is among the most unique and
richest on a per area basis. Its biological importance is not only due to its remaining intact
forest, but also due to its high plant diversity, with more than 3,500 species recorded in the
area. This represents about 45% of species recorded in the country. In fact, the highest
number of endemic plant species is found in Sierra Madre, having 58% endemism. Clearly,
there is a need to share the importance of these native species to more people so we can all
work together to protect and conserve them.
Thankfully, we have this field guidebook on native trees in Quirino. We are grateful to the
Sustainable Environment for Rural Development Association, Inc (SERD) for their hard work
in producing this valuable resource material. Hopefully, through this book, we will be able to
empower more people to become advocates of forest protection and conservation. We look
forward to partnering with them in the future.
Thank you.

Message
Like other living things, trees have places of origin. Each species has found its niche in nature
having adapted to the conditions set by the biotic and abiotic components of its original home
and evolved to its present state. Native trees are vital in the survival of other organisms that co-
evolved with them and in the preservation of biodiversity.
Quirino, nestled at the slopes of the Sierra Madre Range, is blessed with a variety of native tree
species that need to be sustained and protected for their importance in the environmental and in
various ecological services and economic activities in the area. They make up the vast forest
cover which supplies drinking water to the people, provides irrigation system for agriculture,
serves as a dwelling place for the endangered animal species indigenous to the province, and
protects the area from flood and other extreme weather disturbances brought about by the
climate change.
Concerns about native trees have gained new significance in peoples’ environmental awareness
and conservation initiatives. Because native trees are adapted to the locality’s soils,
temperature, amount of sunlight and rainfall, they can be propagated and managed with ease.
Native trees are resistant to pests, diseases and can withstand weather conditions that the zone
experiences such as typhoons and monsoons.
The growing population of Quirino should be more informed and educated about the
province’s natural resources such as the native trees and how these resources are preserved.
Educating the people, young and old alike, will make them more aware about the environment
and value the natural landscape for biodiversity and aesthetic beauty. This education can come
from seeing trees in schools, arboretums, parks, wildlife areas and forested zones;
understanding how these trees, the environment and living organisms including humans are
interrelated; and appreciating how these trees provide clean air, filtered water, shade, food and
soil that all residents depend on.
The book Field Guidebook on Native Trees within Quirino Forest Landscape documents
important characteristics of the native trees such as habit of mature trees, fruit appearances,
profile of mature/immature inflorescence, fruit clusters, leaf arrangement, timber classification,
conservation status, distribution, other notable features, uses and even the vernacular name of
each featured native tree. As an invaluable resource, the guidebook provides students
informative and engaging experience about the indigenous trees. Populated with photos and
interesting facts, it builds interest and fun among the users. Students’ engagement with the
guidebook will help them appreciate native trees and eventually become good stewards on the
preservation of the environment, in general, and the native trees, in particular.
“Trees do not preach learning and precepts. They preach, undeterred by particulars, the ancient
law of life (Herman Hesse).” Like the trees, let us be deeply rooted with our mission and let us
aspire to grow and flourish. Let us disperse the seeds of knowledge and understanding so that
others may live. For in doing so, we find life’s meaning.

Foreword
The Philippine forest is one among those recognized with the highest biodiversity in the world.
However, there is a great unknown among the variety of biological materials that comprise this
diversity. It is lamentable to note that only few experts deal on the nomenclature of the diverse
plants and animals that comprise the forest ecosystem, hence a dearth on publications in these
fields of study. There are a number of publications on birds with beautiful colored pictures but
with limited circulation and patronized only by ornithologists. But for plants, although most
were already identified, there is a dearth of references available on their detailed botanical
descriptions. Even for trees - the large plants in the forest that are supposedly more readily
identifiable and easily describable - there are no ready reference materials that are in circulation.
The available publication at present is the Lexicon of Philippines trees (revised) (Rojo, Justo P. Los
Baños: DOST-FPRDI, 1999) which is a "collation of information mostly from revision of plant
groups in botanical/ taxonomic journals and books dealing with plants in the tropics
particularly in the Malesian Region and surrounding areas". Just like the first edition (Salvosa
Felipe M. A foresty lexicon of Philippine trees. College: FPRI, 1960) , the 1999 Lexicon presents
complete and detailed taxonomic descriptions of each species included.
With the advent of technology, i.e. the internet of things (IOT) and in the social media, there are
many accessible blogs and links online that provide information on many botanical species
available on their databases (many on ornamental plants, some on trees). With good WiFi
connection, some of these are instantly accessible online in many blogs, others as e-books in pdf
formats usually available through officially registered libraries that may require registration or
membership. Some are with commercial motives, others into business adverts. It is obviously
noticeable that their websites are user-friendly and attractively dynamic that banner beautiful
and colorful pictures of the plant species they feature. The eye-catching images cater to
everybody of all walks of life, regardless of personal inclinations or field of interest. For the
science-inclined women and men who are more interested into the technical details of plant
description and characterization, much more is desired. More in-depth descriptions (botanical,
taxonomic, systematics) are preferred by biologists, botanists, foresters, and plants enthusiasts.
Being able to go back and review reference materials is usually done, so the availability of a
readily accessible hardcopy (a book, for example) is much preferable. The nomenclature and
identity of a plant species encountered may be ascertained if referred to and compared with the
reference material.
It is in this regard that this book focused on native tree species will be very useful not only in the
academe - for professors and students alike - but also to the field women and men involved in
botany, forestry, or environmental science. Although quite limited in scope, geographical- and
material- (50 species to be exact) wise, the details of known relevant features given for each
species and the pertinent physical characters clearly shown in the colored pictures capture the
pertinent characters of the tree that defines the doubtless identity of that particular species. It is
worthy to mention that writing a book of this kind is a way of conserving the native tree species
included in the book. With many of them under various categories of endangerment (critically
endangered, vulnerable, threatened, etc.), these trees are permanently preserved in hardcopy
(and electronic copy as well when the e-book form shall have been uploaded) readily available
as published.
The author and her team deserve commendation in coming up with this book in a coffee table
book format that is attractive and readable.

Part I. Introduction
The Author found her heart amongst the native trees which caused her to get
interested in them. Why native trees? Because native trees are very important in the
web of life. They are the foundation of our natural ecosystems (Lantican, 2015).
They provide food and shelter to wildlife much better than introduce tree species.
Native trees also adapt naturally to its local surrounding; thus, are more resilient
than any other tree species (Tarriela, 2018). They also possess the natural ability to
recover from damage caused by pests and diseases and even turbulent weather
conditions (Lantican, 2015).
In recent decades, there had been a sharp decline in the population of native trees
because of extractive and destructive human activities. Deforestation, replacement
by invasive alien species, and establishment of monocrop plantations that only
propagate commercially popular varieties of trees have been the major contributors
to population drop (Green Convergence, 2012). Compounding the problem is the
effect of rapid global climate change on plant phenology (Corlett & Lafrankie, 1998)
which have been affecting the flowering and fruiting of many native tree species.
The province of Quirino is part of the Central Sierra Madre which is identified as
one of the last frontier of natural forests in the country. The author has been
working in the province for almost 18 years now and through those period, she has
been an eyewitness of how forest cover declined and continue to decline due to
expansion of agricultural production, especially corn farming, in forest land areas.
With this, as a forester, the author has been involved in implementing extension
projects geared towards sustainable forest management and in conducting
researches which uncover information about the remaining forests in the province.
In 2016, the first leg of biodiversity inventories was conducted in the barangays of
Eden and Dibibi in the municipality of Cabarroguis, the capital town of Quirino.
The research activity focused on the assessment of the diversity and functions of
secondary forests by undertaking physiognomy (structure) evaluation of the
forests, biological diversity measurement of canopy trees and undergrowth species,
and functional descriptions of the forests and the species. At that time, the author
and her researcher assistants hoped that the output could be used as basis in
crafting the management and protection plan for the two barangays.
Results of the inventory conducted revealed that the forests of Eden and Dibibi
hold considerable advantage for both ecological and economic use. Many of the
plants found thereat have ecological and other potentials. Diversity, structure and
function of forests studied were in the early stages of self-restoration. The forests
contain diversified assemblage of early successional and climax species. Moreover,
the density of canopy and the undergrowth layers provide a fully stocked and
diverse forest in the future. It was projected, therefore, that the forests in the said
barangays can potentially become a major carbon sink of the province in the time
ahead.
However, almost all of the sampled canopy and undergrowth species revealed very
few individual trees. Only few species (e.g., Shorea contorta) are expected to
“endure” individual extirpation because of their abundance in the two sites. It was
concluded that in terms of land use, mix of economically viable and lesser-used/
lesser known species may lead to two “lose-lose” scenarios if not properly
managed: people continuously replacing economically unimportant species with
“money trees”, like Gmelina and Mahogany, and people becoming more aggressive
Pterocarpus indicus
in harvesting economically important individuals to “edge out” competitors over
land resources.
1
In 2018, another rapid tree diversity and timber resources assessment was
conducted in 12 barangays located in areas categorized as “forest landscape.”
These barangays include Ifugao Village, Baguio Village and Don Mariano Perez
in the municipality of Diffun, barangays of Calaocan and Dingasan in the
municipality of Cabarroguis, barangays of San Manuel, Victoria, and Diodol in
the municipality of Aglipay, and barangays of Balligui and Jose Ancheta in the
municipality of Maddela. These barangays are the project site of the Forest-
Foundation funded project titled “Multi-stakeholders Collaboration for the
Sustainable Management of Quirino Forest Landscape” (QFLP).
The study sites are generally termed as “Tropical Evergreen Lowland Forest” or
“Dipterocarp Forest” following the classifications of Fernando et al (2004) and
Tamesis (1948). Dominant species in low-lying open forests, like that of Eden
and Dibibi, include Dungon (Heritiera sylvatica); Magabuyo and Banato (Mallotus
philippinensis), were widespread in closed ridges while Binuang (Octomeles
sumatrana) stands were found prevalent in upper slopes of Dingasan.
The forest assessment team recorded that three out of five most frequent species
in the sampled sites are dipterocarps, to include White lauan (Shorea contorta),
Tanguile (Shorea polysperma), and Mayapis (Shorea palosapis) while the other two
most abundant species are Narra (Pterocarpus indicus), and Magabuyo (Celtis
philippinensis). These are all considered “climax” trees since mature individuals
of such dictate the canopy, structure, recruitment, and general functioning of the
forest.
Other notable trees sighted and reported by locales include Red Lauan (Shorea
negrosensis), Hagakhak (Dipterocarpus validus), Binuang (Octomeles sumatrana),
Balobo (Diplodiscus paniculatus), Nato (Palaquium luzoniense), Tuai (Bischofia
javanica), Lamio (Dracontomelon edule) and Mountain Tapinag (Sterculia montana).
2
White Lauan (Shorea contorta), Kalingag (Cinnamomum mercadoi), Red Nato
(Palaquium luzoniense) and Malak-Malak (Palaquium philippense); and other
threatened species include Bitongol (Flacourtia rukam), and Malakatmon
(Tetracera scandens).
With all facts gathered regarding the state of remaining forests within the “forest
landscape” project area, advocacy and other activities leading to the
development, management and protection of remaining natural forests were
done from 2016 to present. Orientation on various environmental laws to the
members of the different barangay local government units were undertaken and
the response of the different BLGUs was overwhelming. Technical assistance in
crafting and enacting barangay ordinances declaring remaining forests as
“community watersheds” were accomplished. The identification of community
watershed for each of the barangays is important since these areas “sources of
water supply for specific local communities” (DENR-DILG JMC NO. 98-01). An
aggregate area of 6,916.24 hectares was declared as community watersheds
(digitized declared community watershed in the twelve barangays shown in
Figure 1A, 1B, 1C and 1D) through barangay ordinances. These barangay
ordinances provide guidance to the BLGUs on what are the allowable and
prohibited acts inside the declared community watersheds including penalties
for activities that may be committed thereat.
Since a lot of the forest trees identified during the conduct of inventory are
native trees, local leaders and BLGU officials were consulted as to their
willingness to identify and declare premium species of native trees as “mother
trees”. “Mother trees” will be the sources of seeds and seedlings for future
reforestation/rehabilitation activities of concerned entities in the area and in
other parts of the province. Once identified as mother trees, these will be
marked and geotagged as well as protected from any form of cutting or
harvesting. The acceptance was tremendous that eventually led to the
identification, marking and geotagging of 305 native mother trees within the
twelve barangays. Signages were prepared and installed in each of the identified
mother trees to prevent cutting. Most of these mother trees are featured in this
book. A map showing the relative location of these mother trees is shown in
Figure 2A and Figure 2B.
From just being an eyewitness of forest cover decline and being involved in
conducting inventory and restoring forest cover and various undertakings
completed in between, the author is coming up with this Field Guidebook on
Native Trees found within the Quirino Forest Landscape. This book is an
offshoot of the research studies and extension projects conducted by the author
and her research team. Originally, the book is intended only to showcase tree
diversity within selected areas of Quirino, but eventually expanded to be used
as basis for future planning and policy formulation by LGU concerned and to
serve as reference book for BS Forestry students especially those taking
Dendrology. Copyright and book number were obtained from the National
Library. Copies of this book shall eventually be distributed to the different local
government units in the province, as well as, in the library of the university to Pterocarpus indicus
serve as reference.
3
The difficult task of going back to the field and finding the different native trees
in their natural habitat within the almost 7,000 hectares declared community
watershed was started late 2018. It was a long process and tedious work not
only in getting photos but also monitoring their flowering and fruiting stage,
and in researching crucial information about these trees. Despite the hardship
and difficulties, coming up with this book is all worth it.
The author hopes that students will be able to appreciate native trees and their
roles in ecological balance and would also become advocates for its sustainable
management and protection.
