The presence of around 800
species of vascular plants, 100 plus avian species, significant species of
mammals, reptiles, amphibians, fishes, insects and other invertebrates is
indicative of the biological richness of Sta. Cruz. The variety of Sta. Cruz
habitats includes two zones ranging from upland and lowland rainforests and
costal environment of mangroves, seagrass and coral reefs.Sta. Cruz’s portion of Mt. Apo is
dwelled by 104 species of birds with some sightings of Philippine and Mindanao
endemics. Pithecophaga jefferyi
(Philippine Eagle) ranks first in terms of faunal species that has high
conservation value. The forest patch in Sibulan, Tibolo, Jose Rizal, Coronon,
Zone II and Sinoron serve as home to a pair of Philippine Eagle and other
critically endangered species such as
the Shorea negrosensi (Red Lauan) and
Grammatophyllum wallisii, a species
of orchids native in the Philippines and sighted in the forest of barangay Jose
Rizal. Some montane mammals such as Pygmy Squirrel, Brown Deer and fruit bats
are almost endemic to MANP. Other birds like Mindanao Jungle Flycatcher,
Mindanao Pygmy Babbler, Mindanao Lorikeet, Mindanao Racket-tail, Apo Sunbird, Apo
Myna and Grey-hooded Sunbird are found nowhere else.

In separate occasions from
2020-2022 two observations of the endangered Japanese Night Heron were recorded
in barangay Darong and Zone I. Japanese Night Heron is a rare migrant species
of night heron found in East Asia. It breeds in Japan, and one of its winter
refuges is Mindanao, Philippines. The sighting record of this bird is crucial because
the Japanese government has not considered the wintering destination of
Japanese Night Herons in its conservation mechanism, which means that as
wintering host the Philippines, particularly Mindanao should establish an
effort to protect this bird in its entire period of stay.

The encroachment of farms and
other establishment in MANP, as well as the continuous utilization of coastal
areas into industrial uses has made Sta. Cruz one of the biodiversity hotpots
in Mindanao. Biodiversity hotspot is a biographic sites with significant levels
of biodiversity that is threatened by human habitation.
Below is the list of flora and
fauna in Sta. Cruz that are classified critically-endangered, endangered,
vulnerable and near threatened. The International Union for the Conservation of
Nature (IUCN) is being used in this table as reference but to some extent the
Administrative Order No. 2019-09 of the Department of Environment and Natural
Resources is also applied.

Migratory Shorebirds in Sta.
Cruz
While
Sta. Cruz hosts several endemic species, it equally has excellent record of
migratory shorebirds as it forms part of the East Asian-Australasian Flyway,
one of the world’s great flyways of migratory birds. At its northernmost it
stretches eastwards from Taimyr Peninsula in Russia to Alaska. Its southern end
encompasses Australia and New Zealand. Between these extremes the flyway covers
much of eastern Asia, including China, Japan, Korea and Southeast Asia including
the Philippines.

In
the absence of local legislation protecting migratory birds in Sta. Cruz there
is a need to strongly work with DENR and barangays concern so that these birds
will be taken cared of as they winter in identified mudflats and wetlands of
the municipality. The Philippines is a member of the Convention on the
Conservation of Migratory Species and Wild Animals and thus endeavours to
protect migratory species through implementation of its Wildlife Conservation
and Protection Act (RA 9147).
Marine Biodiversity
Sta.
Cruz has around 28 kilometers of coastline, the longest in Davao del Sur. The
creation of 3 Local Conservation Areas somehow impelled marine resource conservation
in barangays Bato, Tuban-Tagabuli and Astorga. Being part of the huge Davao
Gulf, Sta. Cruz is home to several marine species including dolphins and
whales. Aside from cetacean species, Sta. Cruz is also home to various aquatic
species as it serves as breeding and nursery ground for small and pelagic
species, with frequent sightings of Whale Shark, Sea Cow, Hawksbill Sea Turtle
and Green Sea Turtle.

Cave Biodiversity
Sta.
Cruz has only one cave located in barangay Saliducon. Although it is neither a
protected area nor part of a key biodiversity area, Saliducon Cave is home to
several flora and fauna which can be subjected to comprehensive conservation.
For
fauna, Saliducon Cave and its perimeter are confirmed dwelling place of
vertebrates like Long-tailed Macaque, snakes and invertebrates species such as
Asian Palm Civet, Philippine Tarsier, swiflets and bats. Rhinolophus spp was observed inside the cave along with other
wildlife species including spiders, Big-eyed Frog, Sun Skink, Whip Scorpion,
crickets and millipedes. There were also sightings of fresh water shell inside
the cave.
Present Biodiversity
Conservation Efforts
A
milestone for biodiversity conservation in Sta. Cruz, Davao del Sur was
officially started when the local government institutionalized the Environment
and Natural Resources Management Division (ENRMD) under the Office of the Municipal
Mayor in 2020. However, prior to the creation of ENRMD there were already
programs and activities undertaken by the LGU through the Tourism Office, which
practically took the lead in planning and implementing conservation programs to
counterpart to its aggressive stance towards ecotourism development.
Pista
sa Kinaiyahan is an environmental festival every 3rd to 4th
week of April that highlights activities of giving back to Mother Nature the
gratitude for continuously providing ecosystem services to Sta. Cruzians such
as the water we drink and the air we breath. Tree growing, advocacy campaigns
and clean up drive are just some of the activities conducted every Pista sa
Kinaiyahan. Discreet as it may be unlike other festivals, Pista sa Kinaiyahan
gained the support of National Government Agencies (NGA) and private sector as
their venue for Corporate Social Responsibility (CSR) initiatives and is now one
of the longest-running environmental festivals in Mindanao.
Ecotourism
is another strategy that Sta. Cruz employs towards biodiversity conservation by
developing eco sites as tourism attractions engaging the community as major
stakeholders, transforming them into eco site managers and as stewards of their
natural resource base. As of this writing there are seven (7) Community-based
Sustainable Tourism (CBST) sites in Sta. Cruz operating and managing a
biodiversity-friendly tourism enterprises.
Taking
advantage of its good rapport with national agencies and private sector over
the years, Sta. Cruz has been involved with partnership program for
biodiversity conservation. Enumerated in table below are list of biodiversity
conservation programs undertaken by LGU Sta. Cruz.

Threats to Sta. Cruz
Biodiversity
Recognized
as one of the biologically-diverse municipalities – a conservation area facing significant
threats – Sta. Cruz should be treated as one of the biodiversity hotspots in
Mindanao and should be accorded with utmost attention. Hereunder are some of
threats, which, if remain unattended might transform Sta. Cruz’s biodiversity
status from bad to worse:
·
Deforestation
·
Unsustainable Fishing
·
Encroachment of Human Activity in Strict
Protection Zones
·
Illegal Wildlife Hunting and Trafficking
·
Weak Enforcement of Environmental Laws
Future Courses of Action
The ultimate mechanism to conserve biodiversity is habitat conservation. If we want to retain our identified wildlife species we need to expand their dwelling places, in the case of Sta. Cruz our forest should be strongly subjected for protection, as well as our coastal and marine ecosystems.
However, alternative systems should be in placed to underscore strategies that will also benefit communities residing close, or within the conservation areas. The following are courses of actions that are considered as having viability:
First, support biodiversity-related researches to further appreciate the biological importance of Sta. Cruz conservation areas.
Second, support Community-based Sustainable Tourism program to empower local communities in sustaining biodiversity-friendly enterprises.
And third, declaration of the following sites as wildlife sanctuaries: (1) Purok Dagsa, Tuban, Sta. Cruz Migratory Bird Sanctuary, (2) Portions of Tan Kim Kee Estate, Tagabuli as Wildlife Sanctuary and (3) Portion of Tagabuli Highway, Yap Property, as Wildlife Sanctuary. #
