Mangrove species, viz., Avicennia officinalis, Avicennia marina var. acutissima, Avicennia marina (dwarf), Rhizophora mucronata, Sonneratia alba, Aegiceras  corniculatum, Kandelia  candel were chosen for measurement of height of the tree and girth or circumference. The sampling was random and at least 50 records were made. The girth is measured by the tape. The measurement of the height is made with the help of abny level. The Tables 1 to 8 records the values for girth, height and canopy cover as well as for correlation coefficient (r). There correlation between girth and canopy in all the species studied however in case of Avicennia officinalis and Aegiceras corniculatum girth and height show more co-relation than girth and C. cover. The positive co-relation observed between girth and canopy is more or less 0.7 except Avicennia marina (dwarf) Excoecaria agallocha and Aegiceras corniculatum. The co-relation is observed in girth and height is difficult to explain. This case is observed in Avicennia officinalis and Aegiceras corniculatum.

Vegetasi mangrove merupakan komunitas tumbuhan yang hidup di zona pasang surut di sepanjang garis pantai dan dipengaruhi  oleh  kualitas  lingkungan.  Meningkatnya  kebutuhan  manusia  menyebabkan  banyaknya  hutan  mangrove  yang ditebang, diubah untuk berbagai kepentingan seperti pertambakan, pemukiman dan fasilitas–fasilitas pelabuhan.Teluk Kupang memiliki wilayah pesisir yang cukup kaya sumber daya, salah satunya adalah hutan mangrove.Tujuan penelitian ini adalah untuk mengetahui  jenis  dan nilai  kerapatan, frekwensi, dominansi  dan INP mangrove  di Teluk Kupang.  Pengambilan  data menggunakan metode Petak Contoh (Transect Line Plot) dengan menghitung jumlah spesies (pohon, anakan dan semai), jumlah  individu  masing-masing  spesies,    persentase  tutupan,  lingkar  batang  dan  menganalisis  untuk  mendapatkan  nilai kerapatan, frekwensi, dominansi dan INP(Indeks Nilai Penting). Hasil penelitian menunjukkan bahwa pada 4 (empat) lokasi pengamatan, ditemukan sebanyak 11 jenis mangrove. Adapun 11 jenis mangrove yang ditemukan adalah; Rhizopora apiculata, Rhizopora mucronata, Rhizopora stylosa, Burguiera gymnorrhiza, Osbornia octodanta, Avicennia officinalis, Avicennia marina, Scyphiphora  hydrophyllaceae,  Lumnitzera  racemosa,  Sonneratia  alba  dan  Aegiceras  corniculatum.  Jenis  mangrove  yang memiliki indeks nilai penting tertinggi untuk tingkatan pohon yaitu Rhizopora mucronata (INP :299,6) dan terendah adalah Rhizopora stylosa (INP : 18,5), untuk tingkatan pancang/anakan jenis mangrove yang memiliki indeks nilai penting tertinggi sekaligus terendah adalah Rhizopora apiculata (INP : 202 dan 39,62). Sedangkan untuk tingkatan semai, jenis yang memiliki indeks nilai penting tertinggi yaitu Soneratia alba (INP : 174) dan terendah adalah Burguiera gymnorrhiza dan Scyphiphora hydrophyllaceae (INP : 11,80).

Abstract. Raganas AFM, Hadsall AS, Pampolina NM, Hotes S, Magcale-Macandog DB. 2020. Regeneration capacity and threats to mangrove areas on the southern coast of Oriental Mindoro, Philippines: Implications to mangrove ecosystem rehabilitation. Biodiversitas 21: 3625-3636. Regeneration capacity is important as it determines the fate of an ecosystem. This study assessed six mangrove areas in the southern coast of Oriental Mindoro, Philippines to evaluate their regeneration capacity status. Four mangrove ecotypes were delineated namely seaward, middle, landward and riverine zones at each mangrove ecosystem, where dominant mangrove species were identified and selected for regeneration capacity study. Three subplots measuring 1 x 1 m2 were laid within the five 10 x 10 m2 survey plots established per zone. The juveniles were counted and categorized according to their height classes, using linear regeneration sampling method; where: RCI (≤40 cm) considered seedlings; RCII (41-150 cm) as saplings; and RCIII (151-≤300 cm) as small trees. Potential threats both anthropogenic and natural were determined through key informant interviews. Seven dominant species were identified across ecotypes in all mangrove sites, namely Avicennia marina, Avicennia rumphiana, Ceriops decandra, Rhizophora apiculata, Rhizophora mucronata, Sonneratia alba, and Xylocarpus granatum. RCI (seedlings) is the most abundant across mangrove sites irrespective of the dominant species. Fishpond operation within the mangrove stand is considered a major threat to the juveniles and most mangrove ecosystems. Therefore, protection and constant monitoring of these mangrove ecosystems are necessary to ensure regeneration success in the future.

Mangrove forest ecosystems have a very important role for humans and the environment, so to prevent further damage needs to be done identification of tree species composition and structure of mangrove forest stands. For the purpose of this research is to know the composition of tree species from the level of seedling to the tree and to know the structure of its stand. Data collection methods used are Inventory of mangrove species using Indonesian mangrove determination keychain and data analysis by calculating important value index, Diversity index, relative frequency and horizontal structure analysis. The results showed that the largest tree density structure was Rhizophora mucronata of 225 trees / hectare, Avicennia marinna of 145 trees / hectare, Sonneratia alba of 65 trees / hectare and Avicennia officinalis of 65 trees / hectare and had only one crown layer namely strata A which is dominated by Rhizophora mucronata tree which has an average free height of 9 m branch with total height 12 m and diameter 29 cm. For this reason, planting efforts need to be increased to increase the number and composition for coastal protection.

This research conducted on June-September 2016 with purposive sampling methods with three station. Based on the results of the research are nine mangrove species found are rhizophora mucronata, sonneratia alba, nypa fruticans, hibiscus tiliaceus, ipomoea pescaprae, acanthus ilicifolius, gymnanthera paludosa, wedelia biflora, and scirpus sp. Diversity of tree mangrove are low (H’ station 2=0,95 and H’ station 3= 0,15). Diversity of sapling mangrove are low with H’ in station 1, 2, and 3 are 0,2; 0,68; dan 0,08. And the diversity of mangrove seedling and lower plants are medium with H’ in station 1, 2, and 3 are 1,17; 1,56; and 1,48. Environment condition in all station is relatively good to support the life of mangrove plant. That is temperature  28-30 0C; pH 7-8; DO 4,0-6,5 mg/l; salinity 6-9 ppt; and sandy mud substrate.
