Forest and vegetation

Viga is a biodiversity hotspot. Its lush rainforest is home to Philippine brown deer (Rusa marianna), flying foxes, and other endemic bat species, warty pigs, civets, cobras, giant pythons, monitor lizards, sailfin lizards and other endemic animals. Exotic bird species such as Philippine hornbill, rail, parrot, bittern, egret, pheasant, coot, lapwing, plover, Philippine duck, quail, owl, oriole, kingfisher, swiftlets and many more are also found. In fact, a record of "Philippines Birding Trip Reports" has found out many bird species in several portions such as the watershed and timberland forests reserve where scattered deer populations are also usually reported. Unfortunately, one bird subspecies, the Catanduanes Bleeding-heart (Gallicolumba luzonica rubiventris) had experienced over-exploitation in the late 20th century. Although most forests are still intact, this species has suffered over-hunting. It is very rare and believed to be near extinction or already extinct as its last reported specimen was collected in 1971.

The Southern giant slender-tailed cloud rat (budkon/bugkon) which is found only in Catanduanes and the southern half of Luzon Island, is still widely reported. It is critically endangered as humans hunt them for food and for some extent, as pets. In mainland Luzon, sightings of this wonderful creature is already rare while in Marinduque, it is generally considered extinct.

Flora and fauna

The Catanduanes narrow-mouthed frog (Kaloula kokacii), an arboreal amphibian which is found only in Catanduanes and some parts of Bicol, enjoys its diversity but being carefully monitored. Clearing of some forests may pose a threat to amphibian species. An amphibian Hylarana similis is found only in Catanduanes and Luzon islands. One of the very recent species found in Catanduanes and portions of Bicol region is the new loam-swimming skink, a legless reptile with its assigned scientific name Brachymelesmakusog. The rich dipterocarp forest also harbors numerous tropical plant species including the threatened species of pitcher plants and rafflesia as well as endemic banana varieties. Many highly valuable hardwood trees such as yakal, apitong, palosapis, and molave are still found in the forests though local reports indicate that these species are already threatened. Mangrove forests exist in several coastal areas, but the largest locations are in Banquerohan (Viga-Panganiban).

Marine diversity

The marine environment of Viga is also ecologically rich as its terrestrial zones. Coastal reefs harbor many endangered and threatened types of mollusks such as giant Triton, cowries, abalone, cone snails, conches, octopuses, squids, and nautiluses. Marine mammals are also reported to frequent on its coasts such as species of dolphins and whales which appear in March–June. Many edible marine algae such as caulerpa, valonia, and turbellaria also grow abundantly on its rough coasts. Viga is nestled in the very beginning of the Kuroshio Current; a sea current that runs through Eastern Philippines, Taiwan and Japan. This current performs an array of physical and biological functions in countless marine life like migration and breeding. This explains why migratory fish tracks are usually encountered in its waters. Tuna migration can be seen on its peak in the months of April and May. Dugongs were once known to swim on coasts but this event is already becoming extremely rare.

Viga coast is one of the best spots for flying fish population; a flying fish can attain its fullest size which may weigh 300 grams (11 ounces). Rabbitfish, a kind of reef fish is one of the most heavily exploited marine tropical fish in the locality. Its fry that comes out in shallow coasts during the breeding season (March–May) are fished in large volumes. Approximately 10 million rabbitfish fries are caught annually. That natural event supplies food for many people but its ecological impact can be devastating. Nature advocates started to strengthen their campaign for an eco-dialogue for this matter. Sea cucumbers are also known to be abundant in many islets of the eastern coasts facing the Pacific Ocean.

Climate

Viga has a tropical rainforest climate (Af) with heavy to very heavy rainfall year-round and with extremely heavy rainfall in November and December.

Barangays

Viga is politically subdivided into 31 barangays. ^[7] Each barangay consists of puroks and some have sitios.
