IGUANA  •  VOLUME 13, NUMBER 3  •  SEPTEMBER 2006 185

The semi-arid region of the Motagua Valley in northeastern
Guatemala has been classified as an ecoregion in the classi-

fication developed by the World Wildlife Fund (WWF)
(Dinerstein et al. 1995) based on its biodiversity and high degree
of endemism, among other unique qualities. Because the region
is also highly threatened, the Guatemalan NGO Fundación
Defensores de la Naturaleza (FDN), with the support of The
Nature Conservancy (TNC) and Dutch cooperation, are leading
a participatory and interinstitutional conservation program. 

Description of the Area 
The small (approx. 200,000 ha), semi-arid region of the
Motagua Valley is in the departments of El Progreso, Zacapa,
and Chiquimula, and contains two habitat zones: Subtropical
thorn scrub and subtropical dry forest (TNC and FDN 2003).
The valley is surrounded by the Sierra Las Minas, with peaks
reaching to 3000 m above sea level creating a natural barrier to

HABITAT CONSERVATION IN THE MOTAGUA VALLEY

�

The semi-arid region of the Motagua Valley is seriously threatened. Despite its importance and singularity, it is barely represented in the
Guatemalan Protected Areas System.

the moisture originating from the Atlantic (TNC and FDN
2003). With annual precipitation of approximately 500 mm per
year, the area has the lowest annual precipitation recorded for
any part of Central America (Powell and Palminteri 2001),
whereas the surrounding mountains receive up to 3000 mm of
annual precipitation (Powell and Palminteri 2001).

Precipitation data indicate a rainy season extending from
May to September. The average relative humidity ranges from
60–72%, and the average temperature varies from 22–28 °C
(Castañeda 1997), reaching a maximum of 45 °C during the
warmest months of March and April, and a minimum of 7 °C
in December (Valle et al. 1999).

Vegetation
The climatic conditions of the region have resulted in the devel-
opment of caducous vegetative communities, in which leaves fall
at the beginning of the dry season and appear at the beginning
of the rainy season (TNC and FDN 2003). Thorn-bearing
species make up approximately 50% of the plant life, hence the
descriptive habitat name of “thorn scrub” (Castañeda and Ayala
1996). With the exception of the gallery forests, in which the
constant flow of water permits the development of very differ-

ent and much greener vegetative communities, which provide a
refuge to many animal species, the lower elevations of the region
are dominated by thorny species such as the Cactaceae, Acacia,
and leguminous shrubs (Powell and Palminteri 2001).

Recent studies of the thorn scrub in the Motagua Valley
have documented the presence of 107 families and 598 species
of plants, of which 140 are trees, 89 shrubs, 273 grass, 74 lianas,

Several bromeliads and species of cacti, such as this Melocactus, are
threatened by illicit extraction.

12 epiphytes, 4 parasitic species, and 3 aquatic species (Véliz et
al. 2005). The most diverse families are Asteraceae and
Euphorbiaceae with 46 species each, Fabaceae with 41, Poaceae
with 39, Mimosaceae with 28, Caesalpiniaceae with 20,
Convolvulaceae with 18, and Boraginaceae, Cactaceae, and
Solanaceae with 15 species each. 

Geologic processes affecting the region have created isola-
tion that has favored plant speciation, producing a number of
new species with distributions restricted to the Motagua Valley,
for example, various Cactaceae, Euphorbiaceae, and
Mimosaceae (Castañeda 1997, Valle et al. 1999, Morales 2003).
The endemic bromeliad, Tillandsia xerographica, is in danger of
extinction. It, along with species of cacti in the genera
Mammillaria and Melocactus, are extracted illegally for the orna-
mental plant trade.

Among the most common and typical species in the thorn
scrub of Guatemala are Guaiacum coulteri, Caesalpinia velutina,
Cassia emarginata, Cassia skinneri, Haematoxylon brasileto,
Leucaena collinsii, Ximenia americana, Bursera schlenthendali, B.
graveolens, Acacia farnesiana, Prosopis juliflora, Juliania adstrin-
gens, Stenocereus pruinosus, Pereskia lychnidiflora, Nopalea
guatemalensis, Pilosocereus leucocephala, Cordia dentata, and
Cordia truncatifolia (Véliz et al. 2005).

Many important tree and shrub species are used by the
local inhabitants for firewood, wood for small and medium-
sized industry or crafts, and as a source of medicinal plants, food,
and ornamentals (Castañeda 2004). The main species that make
up the cover in the thorn scrub, recognizing the limitations of
the zone, are the Ceibillo (Ceiba aesculifolia), Orotoguaje (Acacia
deamii), Yaje (Leucaena diversifolia), Aripín (Caesalpinia
velutina), Mountain Oak (Bucida macrostachya), Jiote (Bursera
simarouba), Caraño (Juliana adstringens), Guayacán (Guaiacum
sanctum), and the Barreto (Plocosperma buxifolium) (Castañeda
2004). The Barreto and the endemic Motapino (Mimosa zaca-
pana) also have ornamental uses (Castañeda 2004).

Fauna 
The semi-arid region of the Motagua Valley is home to a greater
diversity of species in some groups of vertebrates compared with
other types of forest, largely due to the interactions between the
riverine and semi-arid forests (TNC and FDN 2003). The pres-
ence of 48 species of mammals and 101 species of birds has been
reported (Valle et al. 2003), some of which make use of the gallery
forest that provides them with food and sites for reproduction
(TNC and FDN 2003). The bird families Columbidae,
Tyrannidae, Icteridade, and Fringilidae are sufficiently abundant

as to be considered characteristic of the region (Land 1970). The
valley is the only site in Central America where the Russet
Crowned Motmot (Momotus mexicanus) is found, a species that
is considered to be a reliable indicator of high-quality habitat.
Nevertheless, recent studies (Perez 2003, Nájera 2004) indicate
that most bird species whose presence was recorded in the valley
are habitat generalists and little affected by disturbed habitat.

The threatened mammalian species in the region include
the bats Pteronotus dhabi, P. parnelli, and Leptonycteris curasoae,
the Armadillo (Dasypus novemcinctus), which is endangered due
to hunting, the skunks (Conepatus semistriatus, Mephitis
macroura) due to exploitation for medicinal uses, Cacomistle or
Bassarisk (Bassariscus sumichrasti), and the Water Possum
(Chironectes minumus), which is threatened by the advance of
the agricultural border (Valle et al. 2003).

Sixteen species of amphibians and 54 reptiles have been
reported in the Motagua Valley (Acevedo 2004). The frog,
Craugastor inachus, that was only recently described (Campbell
and Savage 2000) is endemic, and the salamander, Oedipina tay-
lori, is a regional endemic (Acevedo 2004). Among the reptiles
is the Guatemalan Beaded Lizard (Heloderma horridum charles-
bogerti), an endemic subspecies that is in serious danger of
extinction. Recent studies of this species (Masaya 2005, Ariano
2003) report that, even in the most optimistic scenario, the sur-
viving population of H. h. charlesbogerti is only around 174 indi-
viduals (Masaya 2005).

The Conservation Plan
In 2003, the FDN and TNC undertook the task of creating a
Conservation Plan for the semi-arid region of the Motagua
Valley, in view of the importance of biodiversity in this area and
of the urgency to initiate formal actions for its preservation. In
2005, the plan was updated based on new findings and lessons
learned during the first years of work in the Motagua Valley
(FDN and TNC 2005).

The Conservation Plan is based on the methodology of
Planning for the Conservation of Areas (PCA), proposed by
TNC (TNC 1999) and which takes into account all available
ecological and social data on the area in question. The method-
ology is based on the identification and selection of conservation

elements, and an analysis and prioritization of the threats and
advantages affecting those elements. The next step is the defini-
tion of strategies to reduce the threats and maximize advantages.
The final step is to define indicators that can be used to meas-
ure the success of the proposed strategies.

The application of this methodology to the region permits
an approach to the initiative from a local perspective, recogniz-
ing the region’s inhabitants as stakeholders in the conservation
process. To date, the FDN has focused on promoting the decla-
ration of both private and municipal protected areas, environ-
mental education, incentives for forest conservation, ecotourism,
and the enforcement of existing conservation legislation.

Conservation Elements 
The conservation elements identified for the semi-arid region of
the Motagua Valley are: (1) Thorn scrub and dry forest, (2)
Tillandsias and cacti threatened by extraction, (3) Guatemalan
Beaded Lizards (Heloderma horridum charlesbogerti), (4) gallery
forests, and (5) the fluvial system. These five elements and the
key ecological processes by which they are connected are the
focus of the conservation efforts undertaken since 2004 at the
field level.

Threats and Advantages
The most serious threat identified to date is agricultural prac-
tices inconsistent with conservation. Areas of thorn scrub and
dry forest converted for agricultural use have led to the destruc-
tion of 60,000 ha (ca. 30% of the land in the region; Secaira
2004). Also considered serious threats are incompatible forestry

Cacti in the Valley are threatened by extraction.

The Russet Crowned Motmot (Momotus mexicanus) is a species that
is considered to be a reliable indicator of high-quality habitat.

practices, the elimination and extraction of H. h. charlesbogerti,
and non-sustainable selective forest product extraction. The
most threatened elements within the thorn scrub and dry forest
ecosystem are the Beaded Lizards and the fluvial system, because
the factors threatening them are severe and could eliminate them
entirely in the near future if no action is undertaken.

Investigations in the area have identified further factors
leading to the degradation of the ecosystem, including decreases
in the amount of forest, an overall reduction in biodiversity, and
contamination of the rivers. Another element to consider is the
implementation of monoculture systems and the pressures that
the impoverished human populations exert on the local flora
and fauna (Valle et al. 1999).

Nevertheless, factors also exist that favor the conservation of
biodiversity in the Motagua Valley. Among the most significant
of these is the presence of diverse institutions and local govern-
ments that are actively increasing awareness of the importance of
the region and of conservation projects centered on the thorn
scrub and dry forest. Also, since the formal implementation of
the PCA in 2004, an increasing interest in scientific research and
ecotourism in the Motagua Valley has served to directly and indi-
rectly promote the conservation of biodiversity.

Strategic Objectives and Advances
The strategic objectives for the reduction of threats and an
increase in the positive factors affecting the conservation ele-
ments are set for a term of five years from the update of the
Conservation Plan in 2005. One of the main objectives is to

establish formal conservation mechanisms in at least 10% of the
present natural cover, which amounts to having at least 10,000
ha of thorn scrub and dry forest under protection by 2010.
With the collaboration of local governments, communities, and
private landowners, the first protected areas have been estab-
lished in the region adding up to a total of 934 ha, comprised
of municipal regional parks and private natural reserves.
Disputes over land ownership have inhibited further progress on
this objective. In some instances, well-preserved areas with coop-
erative and enthusiastic owners could not be declared as pro-
tected areas due to the lack of property registries. In many other
cases, a lack of realization of the importance of the ecosystem on
the part of local property owners, communities, and govern-
ments works against the creation of new protected areas, thus
the intense focus on environmental education for adults and
children in the region.

One factor stimulating efforts to conserve thorn scrub and
dry forest has been the recent inclusion by the Guatemalan
National Forest Institute of these types of habitat into their
Forest Incentives Program (Programa de Incentivos Forestales,
PINFOR). This program provides economic incentives to pri-
vate and municipal owners to maintain the existing natural veg-
etative cover on their properties or to reforest them with native
species. To date, five private owners have been provided with
economic assistance for choosing to conserve the forest on their
property.

The goal for 2010 with regard to Heloderma horridum
charlesbogerti is to maintain existing population numbers

Guatemalan Beaded Lizards (Heloderma horridum charlesbogerti) are endemic to the Motagua Valley.

(Masaya 2005, Ariano 2003). Beaded Lizards are seriously
threatened by destruction of their habitat, elimination due to
false suppositions regarding the dangers posed by this venomous
animal, and illegal extraction for the exotic pet trade. Various
institutions have initiated their own environmental education
programs to sensitize the local population to the need for pro-
tection. Recently, the national strategy for Heloderma conserva-
tion was developed (Zootropic and TNC 2005), and work
moves forward on the telemetry studies initiated in 2004
(Masaya 2005), as well as environmental education efforts
within the distribution of Heloderma to ensure the protection of
the remnant population of this species.

The strategic objectives for the gallery forests and the flu-
vial system are largely the purview of the FDN team that works
in the adjacent Sierra de las Minas Biosphere Reserve (SMBR).
Since the water supply of the Motagua Valley comes almost
entirely from the Sierra de las Minas, in which 63 permanently
flowing rivers originate, an initiative for the integrated manage-
ment of the water supply has been created (“Fondo del Agua” =
Water Fund). The objective of this project is to ensure the vol-
ume and quality of the water originating in the SMBR for the
long term by providing technical and financial assistance to
improve water management and the river basins (FDN 2004).
For the semi-arid region of the Motagua Valley, the strategic
objective for 2010 is to maintain the quality and volume of
water produced annually by the SMBR, and to ensure the
preservation of the gallery forests of three high-priority river
basins between the Motagua Valley and the SMBR. Work
toward these objectives has been accomplished primarily
through the Water Fund project with the formation of river
basin committees and through education emphasizing the
importance of sustainable usage of hydro resources in the region.

To improve progress towards the fulfillment of the pro-
posed objectives, a plan for the conservation of cultural patri-
mony has been developed and integrated into the existing PCA
in an effort to take advantage of synergies between nature and
culture to increase local and institutional support, education,
and the promotion of sustainable tourism. This Natural and
Cultural Conservation Plan (FDN and TNC 2005) tries to inte-

grate the diverse stakeholders and local institutions through the
formation of an “alliance for the conservation of the semi-arid
region of the Motagua Valley.” The objective of this alliance is
to promote and coordinate activities for the conservation of the
natural and cultural resources of the region, and to extend man-
agement support to national and international organizations for
the implementation of the PCA. The alliance also seeks to gen-
erate political support and to establish strategic alliances with
participating institutions and local governments, to continue
working on the application of effective environmental legisla-
tion, the conservation and recovery of high-priority areas, social
organization, and environmental education, with the purpose of
promoting and consolidating mechanisms likely to preserve the
natural and cultural resources of the Motagua Valley.

Since early 2004, we have made discernible progress on all
proposed strategic objectives, and have learned many lessons.
One of the latter is the necessity and importance of a combina-
tion of interinstitutional alliances and local support to develop
a more integrated and sustainable long-term initiative.
Promoting conservation in this region of Guatemala has been a
challenge, but the participating institutions truly hope that the
conservation efforts that are being implemented will ensure the
permanence of this important ecosystem, as well as fortify and
consolidate diverse areas of conservation in the semi-arid region
of the Motagua Valley.
