Terumbu karang merupakan ekosistem laut yang memiliki biodiversitas tinggi dengan produktivitas yang juga tinggi meskipun hanya menempati 1% bagian dari dasar laut. Data mengenai kondisi umum terumbu karang secara nasional tampaknya telah terdokumentasikan dengan baik. Akan tetapi, dalam banyak kasus, data-data dalam skala yang lebih sempit seperti di tingkat kecamatan dan/atau kabupaten tampaknya masih terbatas, termasuk di perairan sekitar pesisir Situbondo. Berdasarkan data dan fakta tersebut, perlu dilakukan upaya pemantauan (monitoring) dengan melibatkan banyak pihak termasuk komunitas pesisir. Akan tetapi umumnya terdapat masalah berupa keterbatasan kapasitas dan kapabilitas dalam pelaksanaan monitoring tersebut. Untuk itu telah dilaksanakan suatu pelatihan atau \textit{workshop} untuk meningkatkan kapasitas dan kapabilitas kelompok masyarakat pesisir dalam upaya monitoring dan rehabilitasi terumbu karang. Dalam kegiatan tersebut, mitra kelompok masyarakat adalah komunitas pesisir Misi Bahari yang merupakan wadah dan penggerak untuk melakukan upaya pencegahan kerusakan terumbu karang; serta perlindungan dan konservasi terumbu karang di perairan laut Situbondo dan sekitarnya. Secara umum, workshop dan kegiatan lanjutan berlangsung dengan baik dan dapat memberikan peran nyata dalam peningkatan kapabilitas komunitas pesisir dalam pemantauan kondisi terumbu karang; ditunjukkan melalui tercapainya kegiatan pasca pelatihan seperti monitoring bersama kondisi terumbu karang serta perakitan dan penenggelaman apartemen ikan (fish apartment) di Pasir Putih, Bungatan, Situbondo.

In the mining industry, provision of new habitat through land rehabilitation and affforestation is an important step to anticipate the loss of biodiversity, including bird communities. The positive impacts of land rehabilitation and affforestation thus can be identified from results of periodic monitoring. The turnover of bird communities associated with afforestation is related to changes in structural habitat features that provide food and shelter. In this study, we have monitored bird community assemblages and feeding guild structure in revegetated area of karst in Rembang, Central Java. Three locations (EDP, GBC and GBL) were selected and characterized by different land use, vegetational age and floral composition. Surveys were conducted using point count method in early April for three consecutive years (2020-2022). In total, we have identified 32 bird species from 29 genera, 22 families and 9 orders. Most of birds observed considered as generalist, cosmopolitan and well-adapted to various habitat. Total species richness (19.33±3.22 to 20.67±4.12) and value of diversity index (H’ = 2.41±0.14 to 2.56±0.29) were only slightly differed among locations. Species richness and total abundance in each sites tend to increase along periods of observation, suggesting that bird community change in response to further structural habitat changes that occur as vegetations age. Furthermore, higher abundance occurred in larger area or in sites with more native plant species. The feeding guild costisting 7 groups and dominated by insectivore, both based on number of species (46.88%) and individuals (49.07%). Results of the study are expected to help identify more appropriate management of conservation and habitat restoration in the area.
