Walker, [1858]

Aucha velans, the tide-watching mangrove moth, [1] is a moth of the family Noctuidae. The species was first described by Francis Walker in 1858. [2] It is found in Sri Lanka, [3] [4] Singapore and Philippines. [5]

The adult has a wingspan of 28–35 mm. They are found on the stems of Avicennia mangroves in a characteristic position where adults perch head down on tree trunks. Caterpillars are edge feeders of Avicennia species. Late instars reach the ground and pupate inter-tidally under rotting logs or in algal mats. [1] They are major pests on mangroves and considered as severe defoliators. [6]

A mangrove is a shrub or small tree that grows in coastal saline or brackish water. The term is also used for tropical coastal vegetation consisting of such species. Mangroves occur worldwide in the tropics and subtropics, mainly between latitudes 30° N and 30° S, with the greatest mangrove area with 5° of the equator The total mangrove forest area of the world in 2000 was 137,800 km2 (53,200 sq mi), spanning 118 countries and territories.

Bongsanglay Natural Park is a protected area of mangrove forests and swamps on Ticao Island in the Bicol Region of the Philippines. It is located in the municipality of Batuan in the island province of Masbate covering an area of 244.72 hectares. The protected area was established on 29 December 1981 when the area "from Panciscan Point in Bitos Bay up to Bano Sanlay" in Batuan was declared a Mangrove Swamp Forest Reserve under Proclamation No. 2152 signed by President Ferdinand Marcos. In 2000, when President Joseph Estrada signed Proclamation No. 319, Bongsanglay was reclassified as a natural park pursuant to the National Integrated Protected Areas System (NIPAS) Act.

Isla Pulo

Pulo Island, commonly known as Isla Pulo, is a long, narrow island surrounded by mudflats in the Manila Bay coast of Navotas, about 13 kilometres (8.1 mi) north of Manila in the Philippines. It is a sitio in the northern village of Tanza, connected to the mainland of Navotas by a 500-meter long bamboo bridge. The island is known for its mangroves for which it was declared a "marine tree park" and as one of four ecotourism sites in Metro Manila established under the National Ecotourism Strategy in 1999. In 2014, it was home to a resettlement site of about 137 indigent families that mostly occupied the island's southern tip.

Pemphis acidula, commonly known as bantigue or mentigi, is a species of flowering plant in the family Lythraceae. It is a mangrove found throughout most of the tropical Indo-Pacific growing on rocky shores. The genus Pemphis, to which it belongs, was until recently thought to have only this single species, first described in 1775 and long considered the type species, but is now believed to have at least one other.

Environmental issues in Sri Lanka

Environmental issues in Sri Lanka include large-scale logging of forests and degradation of mangroves, coral reefs and soil. Air pollution and water pollution are challenges for Sri Lanka since both cause negative health impacts. Overfishing and insufficient waste management, especially in rural areas, leads to environmental pollution. Sri Lanka is also vulnerable to climate change impacts such as extreme weather events and sea level rise.

Sri Lanka is a relatively small continental island, it exhibits a remarkable diversity of forest types, which are among the biologically one of richest forests in Asia. In these forests plant species show extraordinary patterns of localized distribution. Sri Lanka's forest became one of highest density of species diversity in the world. Sri Lanka natural forests cover about 12,493 km2 29.46% According to the National Red List said, Sri Lanka counts 253 land species, 245 species of butterflies, 240 birds, 211 reptiles, 748 evaluated vertebrates and 1,492 invertebrates. Forest coverage is about 70% tropical dry monsoon forests, 15% tropical moist monsoon forests and 5% tropical lower montane forests. By the dawn of the 19th century, Sri Lanka's forest cover was estimated at up to 70% of the total land area. Since then, the forest cover has decreased progressively over time. Significant loss of Sri Lanka's forest cover was first reported in the 19th century, with the introduction of plantation agricultural crops such as tea and vegetables. Commercial timber extraction policy of colonial rulers (British colonial time also led to clearing of forests in the dry zone. Irrigation development and agricultural expansions have been identified as key drivers of forest cover change.
