Kondisi habitat merak hijau yang semakin menurun kualitasnya, menyebabkan populasinya mengalami penurunan. Fragmentasi habitat dan perburuan menyebabkan populasinya terpecah dalam kelompok kecil, oleh karena itu perlu dilakukan pengayaan (enrichment planting) jenis pohon berbasis fungsi dan model arsitektur pohon yang mendukung habitat merak hijau. Penelitian ini bertujuan untuk mengetahui jenis-jenis pohon penyusun beserta model arsitektur pohon di Petak 117B, RPH Sawoo, BKPH Bondrang, RPH Madiun dan membuat rancangan pengayaan jenis pohon berbasis fungsi dan model arsitektur pohon untuk mendukung habitat merak hijau. Pengambilan data menggunakan metode systematic sampling with purposive start, dengan membuat petak ukur (PU) berukuran 20 m x 20 m, sebanyak 19 PU (IS 5%), jarak antar PU 60 m. Pengambilan data dilakukan dengan mengukur tinggi, diameter batang, dan mengidentifikasi jenis dan model arsitektur pohon. Identifikasi mengenai rancangan pengayaan yang mendukung habitat merak hijau dilakukan dengan memilih jenis-jenis yang sesuai dengan habitat merak hijau, ditinjau dari aktivitasnya yang berhubungan dengan vegetasi (perilaku makan, istirahat, dan tidur). Jenis pohon penyusun Petak 117B, RPH Sawoo, BKPH Bondrang, KPH Madiun ada 3, yaitu: jati (Scarone), sonokeling dan flamboyan (Troll). Rancangan pengayaan dilakukan pada setiap petak tanam berukuran 20 m x 20 m, jarak antar petak tanam 60 m, terdapat 4 Pola (Pola I, Pola II, Pola III, dan Pola Center Area). Setiap petak tanam direncanakan melibatkan pohon-pohon yang memiliki peran untuk optimalisasi habitat burung merak hijau, meliputi fungsi pohon pakan (widoro bukol, serut, dan bayur), fungsi pohon tidur (apak, gebang, bendo, asam Jawa, dan kesambi), dan fungsi pohon peneduh (mimba dan walikukun).

The decreasing quality of the habitat condition of green peafowl leads to their declining population. Habitat fragmentation and illegal hunting cause the fragmentation of the population into smaller and more isolated remnants. It is for this reason that enrichment planting site plan of tree species for green peafowl habitat based on trees function and architecture model is necessary. The present study aimed to investigate the species of trees as well as their architecture model in Compartment 117B, RPH Sawoo, BKPH Bondrang, RPH Madiun and to create the site plan of species of trees based on their function and architecture model to rehabilitate the suitable habitat for green peafowl. Data collection used systematic sampling with purposive start method. This was carried out by making 19 plots (SI 5%) of 20 m x 20 m within a 60 m distance. Data collected were tree height, trunk diameter, identification of tree species, and their architecture model. Design of enrichment planting site plan was carried out by considering function and architecture model of trees in relation to the activities of green peafowl (e.g. diet and roost). Tree species found in Compartment 117B, RPH Sawoo, BKPH Bondrang, KPH Madiun were teak that had architecture model of Scarone, and flamboyant and rosewood that had architecture model of Troll. Enrichment planting was done on the 20 m x 20 m plots using 4 types of patterns (Pattern I, Pattern II, Pattern III, and Center Area Pattern), each of which was consisted of tree species that served the roles in optimizing the habitat of green peafowl. These trees were widoro bukol, serut, and bayur which served the role to provide food, apak, gebang, bendo, asam Jawa, and kesambi which served the role to provide accommodation, and mimba and walikukun which served the role to provide shelter. The distance of each plot was 60 m from each other.
