Universitas Gadjah Mada memiliki luas sebesar 211,9846 Ha dengan ruang terbuka hijau 30%, terdapat pohon sekitar 10.200 pohon. Adanya faktor bertambahnya umur pohon, kesehatan pohon dan lingkungan memungkinkan pohon berpotensi roboh. Penelitian dilakukan menggunakan metode sensus dan eksplorasi purposif pada seluruh kawasan UGM baik unit fakultas dan non fakultas. Ekplorasi menggunakan tujuh kriteria yaitu pohon mati, berbatang miring, batang berpenyakit, bertajuk asimetris, terletak di tebing, terdapat pencekik dan liana, dan terdapat benalu dan pelilit. Skoring tiap pohon dilakukan berdasarkan tujuh kriteria tersebut. Analisis status pohon berpotensi roboh dibagi menjadi empat kategori status yaitu siaga, waspada, darurat dan berbahaya. Hasil penjelajahan didapatkan total pohon berpotensi roboh berdasarkan tujuh kriteria sebanyak 336 pohon. Lokasi pohon berpotensi roboh dijumpai paling banyak pada Fakultas Kehutanan, Fakultas Biologi, Fakultas Teknik, kawasan gedung pusat rektorat, kawasan lembah, masjid kampus dan gelanggang mahasiswa. Pohon-pohon tersebut terbagi kedalam 24 famili, 54 genera, dan 59 spesies. Famili terbanyak didominasi oleh Leguminosae, Sapindaceae, Bignoniaceae, dan Meliaceae. Spesies terbanyak didominasi oleh Delonix reggia, Filicium decipiens, Spatodea campanulata dan Pithecellobium dulce. Hasil analisis skoring didapatkan 166 pohon berstatus siaga, 151 pohon berstatus waspada dan 19 pohon berstatus darurat.

Universitas Gadjah Mada has total areas about 211,9846 hectares. The 30% of this area is a green area. It is dominated by trees with the number of plus-minus 10.200 trees. The increasing age of tree, tree healthy and environmental factors may allow the tree collapsed. This research was conducted by tree sensus and purposive exploration methods in the UGM area, faculties and non faculty units. Seven criterias were used to identify each tree for scoring i.e. dead tree, sloping trunked, diseased stem, asymmetric crown, located on the cliffs, covered by strangler and lianas and covered by parasites and climbers. Scoring was done based on seven criterias of each tree. Status analysis of the potential collapsed tree was divided into 4 status categories i.e. "siaga" (standby), alert, emergency and dangerous. The result showed that total potential collapsed trees based on the seven criterias were 336 individual trees. The location with the most potential collapsed trees are Faculty of Forestry, Faculty of Biology, Faculty of Engineering, Center Office of Universitas Gadjah Mada, Lembah area, Campus Mosque and Gelanggang Mahasiswa. Those trees could be grouped into 24 families, 54 genera, and 59 species. The dominated family were Leguminosae, Sapindaceae, Bignoniaceae and Meliaceae. The dominated species were Delonix regia, Filicium decipiens, Spatodea campanulata and Pithecellobium dulce. The result showed that the status of 166 trees were "siaga" (standby), 151 trees were alert and 19 trees were emergency.
