Analysis of Changes in Health of Coastal Mangrove Forest on the East Coast of Lampung

Abstract

The mangrove forest is a forest ecosystem that supports life for the surrounding ecosystem. However, the area of mangrove forests is decreasing. It is recorded that up to 2016, there is only 2.9 million hectares of mangrove forests in Indonesia. Mangrove forests’ existence needs to be maintained in the surrounding ecosystem. One of the efforts to protect the mangrove forest ecosystem is to see changes in mangrove forest health. This effort can be used as the basis for sustainable mangrove forest management—this research’s purpose—this the real aim of mangrove forests on the east coast of Lampung. The study was conducted at three locations on the east coast of Lampung (Pasir Sakti District, Labuhan Maringgai District, and Way Kambas National Park). The method used was the Forest Health Monitoring (FHM). The results showed that mangrove forests’ health value on the east coast of Lampung had positively changed except for cluster plots 2 and 3. The health of mangrove forests on the east coast of Lampung has increased the forest’s health value. The increase in forest health value is influenced by factors from the indicators used, especially vitality.

Study of Vitality Change in Teak Community Forest Management (Case Study on Teak Community Forest in Natar Sub-district, South Lampung Regency, Lampung Province)

“…As a result, the condition of the trees that make up the stand can provide insight into the health of forest ecosystems. A healthy tree is one that can perform its physiological tasks, has a high level of ecological resistance against pest disturbances and other environmental conditions, and is not susceptible to disease [2]. Based on the type of damage and the location of the damage, the state of the trees was assessed.…”

“…In addition, the health of teak community forests will have a good impact on the fulfillment of forest functions, preferably teak community forests as production forests[19]. Therefore, forest health can be used as a form of control to carry out the main functions of the forests and also to create the sustainability of teak people's forests[2]. In order to assess alterations in the value of the condition of the local forests based on vitality indicators in teak community forests, it is crucial to carry out this research.Ecological measures of forest health, such as vitality, are used to assess the health of forests.…”

Kajian Analisis Struktur Komunitas Mangrove di Muara Jenggalu Kota Bengkulu

“…Penutupan jenis terendah yaitu 0,18-49,68%. Kualitas kondisi tajuk mangrove dapat menurun akibat faktor kerusakan pohon atau karena kekurangan nutrisi karena kualitas situs yang rendah (Ardiansyah & Safe'i 2021). Rendahnya nilai penutupan pada beberapa jenis mangrove seperti Bruguiera gymnorrhiza dan Avicennia marina diduga umur pohon masih ≤ 10 tahun sehingga diameter pohon masih tergolong kecil.…”

Analysis of Damage to Trees in the Coastal Mangrove Forest of East Lampung Regency

“…This damage can occur due to pests or diseases. According to Ardiansyah and Safe'i [28], the type of damage can be caused by various factors, such as disease, pest attacks, weather, and animals. Pests that attack the leaves of mangrove trees are of the type Lepidoptera in the larval stage.…”
