Underutilized Fruit Trees (UFTs) berhasil diidentifikasi, dimanfaatkan, dan dilestarikan oleh kelompok masyarakat hukum adat yang tinggal di Kampung Urug, Jawa Barat. Pada awal tahun 2020, Kampung Urug dilanda banjir dan tanah longsor yang menyebabkan lokasi tempat tumbuh UFTs rusak. Upaya sistematis dan terintegrasi untuk meningkatkan ketahanan terhadap perubahan iklim perlu dilakukan. Peningkatan ketahanan terhadap perubahan iklim dapat dilakukan dengan mendokumentasikan pengetahuan lokal masyarakat hukum adat dalam membudidayakan UFTs dan meminimalisir dampak perubahan iklim serta pendekatan lintas sektoral di tingkat lokal melalui analisis vegetasi dan analisis perubahan kerapatan vegetasi. Penelitian ini bertujuan untuk mendokumentasikan teknik budidaya UFTs, lokasi tempat tumbuh UFTs, menganalisis kerapatan vegetasi tempat UFTs ditemukan, mendokumentasikan pengetahuan lokal masyarakat hukum adat dalam menghadapi perubahan iklim, menganalisis perubahan kerapatan vegetasi selama 10 tahun, menganalisis struktur dan komposisi vegetasi di Kampung Urug. Penelitian ini dilakukan dengan metode penelitian kombinasi. Pengumpulan data dilakukan melalui Focus Group Discussion (FGD) dengan 16 orang, wawancara mendalam dengan 19 orang, dan observasi lapangan. Berdasarkan hasil penelitian ini diketahui bahwa teknik budidaya UFTs yang dilakukan oleh masyarakat hukum adat di Kampung Urug adalah pemilihan bibit (pilihan bibit tatangkalan), penyiapan lahan (nyiapkeun taneuh), penanaman tanaman (melak tatangkalan), perawatan tanaman (ngurus tatangkalan), dan pemanenan (panen). Sebanyak 53 UFTs yang berasal dari 13 spesies ditemukan di 24 placemark yang berbeda. Sebanyak 62% UFTs ditemukan di lokasi dengan indeks vegetasi sedang dan 38% UFTs ditemukan di lokasi dengan indeks vegetasi rendah. Masyarakat hukum adat mendefinisikan perubahan iklim sebagai perubahan musim. Salah satu gejala adanya perubahan iklim adalah terdengarnya suara Presbytis comata yang tinggal di Gunung Pongkor. Pada daerah bervegetasi sangat tinggi terjadi penurunan luas kerapatan vegetasi sebesar 94%. Pada daerah bervegetasi rendah, bervegetasi sedang, dan bervegetasi tinggi terjadi peningkatan luas kerapatan vegetasi, secara berurutan sebesar 1%, 34%, dan 59%. Schima wallichii memiliki Indeks Nilai Penting (INP) tertinggi (41,84%), diikuti oleh Mangifera kemanga (18,77%) dan Sandoricum koetjape (14,75%). Hasil penelitian ini dapat dijadikan sebagai dasar pengembangan program konservasi keanekaragaman hayati. ......Underutilized Fruit Trees (UFTs) have been identified, utilized, and preserved by indigenous people living in Urug Village. However, Urug Village hit by flooding and landslides in early 2020, damaging the location where UFT grew.  Therefore, a systematic and integrated effort is needed to increase resilience to climate change. Increasing resilience to climate change can be conducted by documenting local knowledge of indigenous peoples in cultivating UFTs and minimizing the impact of climate change, also a cross-sectoral approach at the local level through the analysis of vegetation and analysis of changes in vegetation density. This study aims to determine UFTs cultivation techniques, locations where UFTs grow, vegetation density where UFTs are found, find out local knowledge of indigenous peoples in dealing with climate change, changes in vegetation density over 10 years, structure and composition of vegetation in Urug Village. This research was conducted using a combination research method where data collection was carried out through Focus Group Discussions (FGD) with 16 people, in-depth interviews with 19 people, and field observations. Based on this research, the UFTs cultivation techniques carried out by the indigenous people in Urug Village are the selection of seeds (pilihan bibit tatangkalan), land preparation (nyiapkeun taneuh), planting (melak tatangkalan), caring (ngurus tatangkalan), and harvest (panen). A total of 53 UFTs from 13 species  found in 24 different placemarks. A total of 62% of UFTs were found in locations with medium vegetation index and 38% of UFTs were found in locations with low vegetation index. Indigenous peoples define climate change as a change in season. One of the symptoms of climate change is the sound of Presbytis comata who lives on Mount Pongkor (2) There is a decrease of vegetation density by 94% in the area with very high vegetation. There is an increase of vegetation density in the area with low, moderate, dan high vegetation density by 1%, 34%, dan 59%, respectively (3) Schima wallichii) has the highest Importance Value Index (41.84%), followed by Mangifera kemanga(18.77%), and Sandoricum koetjape (14.75%).
