چکیده

Forest damage has an effect on ecological functions, such as the root system of forest trees will be disturbed, floor covering plants cannot increase soil stability, so they are unable to reduce speed water flow which causes erosion and flooding. In general, presence vegetation in area a positive impact, but varies depending structure composition that grows area. This study aims calculate analyze structure, diversity Selorejo RPH protected forest. research was conducted from March 6 July 20, 2022 using survey methods quadratic transects. The results showed contained 4829 individuals 64 species belonging 26 families. At tree level, highest INP value found Trembesi (Samanea saman) with 169.92%. pole Kepuh (Sterculia foetida) 141.05%. sapling is type Arabica Coffee (Coffea arabica) 70.40%. seedling level there only 2 species, namely; Avocado (Persea americana) arabia) 0.00% each at lower plant Tekelan (Ageratina riparia Regel) 63.17%. index for categorized low diversity, while saplings, poles understorey it moderate diversity. Keywords: Damage, Vegetation Analysis, Diversity ABSTRAK Kerusakan hutan memberikan pengaruh terhadap fungsi ekologis, seperti sistem perakaran pada pohon akan terganggu, tumbuhan penutup lantai tidak dapat meningkatkan stabilitas tanah, sehingga mampu mengurangi kecepatan aliran air yang menyebabkan erosi dan banjir. Secara umum kehadiran vegetasi suatu dampak positif, tetapi pengaruhnya bervariasi tergantung struktur komposisi tumbuh daerah tersebut. Penelitian ini bertujuan untuk menghitung mengalisis struktur, keanekaragman di lindung RPH Selorejo. dilaksanakan Maret sampai 20 Juli dengan menggunakan metode transek kuadrat. Hasil penelitian menunjukkan Komposisi Vegetasi terdapat individu dari spesies tergolong ke dalam familia. Pada tingkat Nilai tertinggi jenis saman). tiang nilai . pancang Kopi Arabika arabica). semai hanya yaitu ; Persea americana Coffea arabica. serta bawah Regel).
