Habitat Management Based on Mangrove Sensitivity Assesment in Tulungagung Coastal Area

Abstract

Tulungagung reflects the typical conditions of southern coast of Java, which dominated bay small bays with thin layer of superficial mud sediments and bordered by hilly terrain. Mangrove distribution in Tulungagung located in there locations, Brumbun Beach, Gerangan Beach and Sine Beach. This research aimed to identify the forest structure, habitat sensitivity and completed with management plan in each location. Data collected includes vegetation structure, hydrooceanography, environmental pressure and anthropogenic activities. An interesting finding is that, despite its narrow areas (2,24 Ha), mangroves in Tulungagung have high species diversity (11 species of true mangrove includes Acanthus ebracteatus, Acanthus ilicifolius, Acrostichum aureum, Avicennia alba, Avicennia marina, Ceriops tagal, Excoecaria agallocha, Rhizopora apiculata, Rhizopora mucronata, Rhizopora stylosa dan Sonneratia alba). Rm and Rs stands dominated by >7m height with canopy cover range from 79,4-89,6%. Geomorphological settings and limited mud supply are the primary challenges for mangrove habitat in Tulungagung. On the other hand, observation conservation status and local stakeholders involvement show the need for improvement of mangrove management in Tulungagung coastal areas.

Evaluation of the quality of mangrove ecosystems using macrozoobenthos as bioindicators in the Southern Coast of East Java, Indonesia

“…On the other hand, the southern coast of Java has a small estuary area and is exposed to the waves of the Indian Ocean, causing a lack of supply of coastal sediments and steep topography. Therefore, the mangroves in the southern region receive less attention, so data on these mangroves are lacking (van Oudenhoven et al 2015;Mughofar et al 2018;Saputra et al 2020).…”

“…Mangrove ecosystems on the south coast of Java, especially in East Java, have been severely degraded by human activities, such as land conversion into ponds, agriculture, and plantations (Cambell and Brown 2015;Biswas and Biswas 2019). Some beaches that have experienced degradation are Cengkrong Beach (Mughofar et al 2018), Sine Beach (Saputra et al 2020), Getem Beach, Kondang Merak Beach, and Clungup Mangrove Conservation (Hakim et al 2017;Retnaningdyah et al 2021). Continuing human activities without any countermeasures can reduce the carrying capacity (Malik et al 2015), which decreases the quality of mangrove ecosystem services (Rohila et al 2017;Darmawan et al 2020).…”

Evaluation of Mangrove Water Quality in Pancer Cengkrong, Trenggalek and Sine, Tulungagung, East Java, Indonesia Using Phytoplankton as Bioindicators

“…Cengkrong mangrove restoration in 2008-2009 and 2013-2014 are characterized by high mangrove taxa richness due to planting, which resulted in improved water quality characterized by moderate H' and E, and low levels of eutrophication and organic pollutants characterized by TDI values and low %PTV. Mangroves react as phytoremediators that reduce the organic matter and nutrients levels in the ecosystem, thus reduce nitrate and phosphate concentrations (Saputra et al, 2020). Sine and 2005 succession mangroves have low mangrove taxa richness and high nitrate levels, contributing to eutrophication and contamination of organic matter characterized by high TDI and %PTV.…”

“…On the southern coast of Java, especially in East Java, mangrove ecosystems can be found in Pancer Cengkrong, Trenggalek Regency and Sine, Tulungagung Regency. Cengkrong and Sine mangroves with the area of about 87 ha (Mughofar et al, 2018) and 1 ha (Saputra et al, 2020), respectively, are surrounded by anthropogenic activities such as logging, aquaculture, plantations, and agriculture. In the vicinity of Sine mangrove, there are beach activities, tourism, plantations, and agriculture.…”

Estimation of Organic Content and Carbon Uptake in <i>Sonneratia alba</i> (Smith) Mangroves in Aquaculture Areas: a Case Study in the Marine and Brackish Water Cultivation Area of Probolinggo City, Indonesia

“…Natural forests are a source of carbon storage because they have a high diversity of tree vegetation [1]. Therefore, many efforts have been done for the environmental development so that the amount of carbon dioxide in the air can be controlled by increasing the amount of CO 2 uptake by plants as much as possible in order to release carbon dioxide emissions into the air as low as possible [2]. Mangroves are natural resources on the coast that have functions as protection, maintenance and nature conservation [3].…”
