Abstract

Hutan memiliki peran dalam regulasi siklus karbon dan siklus air, serta keberadaan pepohonan yang sangat penting dalam struktur floristik dan dinamika hutan. Sehingga perubahan pada kesehatan maupun adanya mortalitas pohon tentunya akan mempengaruhi fungsi dan struktur hutan. Penyebab kerusakan dan mortalitas pohon sendiri sangat beragam, mulai dari faktor biotik seperti fungi, liana, serangga; juga faktor abiotik seperti cuaca, temperatur, humiditas, dll. Oleh karena itu, penelitian ini bertujuan untuk mengetahui persentase individu mati terhadap keseluruhan total individu yang ditemukan, serta mengamati faktor resiko yang menyebabkan kerusakan dan mortalitas pohon di Hutan Sumber Pawon, Kediri yang diberdayakan sebagai wilayah konservasi air. Pengamatan dilakukan berdasarkan Tree Mortality and Damage Protocol yang dikeluarkan oleh ForestGEO, dengan mengamati mode tegakan, crown illumination, infestasi liana dan adanya fungi yang mempengaruhi kayu pohon. Hasil yang diperoleh menunjukkan dari total 170 pohon yang ditemukan, sebesar 6,47% individu pohon mengalami kerusakan dan mati. Dari total 11 pohon yang mati, 6 diantaranya mati dalam mode uprooted (U) dan 5 sisanya mati dalam mode broken (B). Proses kerusakan dan mortalitas pohon yang terjadi secara episodik diduga disebabkan oleh adanya faktor biotik seperti liana dan fungi, dan faktor abiotik seperti perubahan cuaca, tekstur dan kelembaban tanah.

Forests have a role in the regulation of the carbon cycle and water cycle, as well as the presence of trees that are very important in the floristic structure and dynamics of the forest. Changes in the health and mortality of trees will certainly affect the function and structure of the forest. The causes of tree damage and mortality are very diverse, ranging from biotic factors such as fungi, lianas, insects; and also abiotic factors such as weather, temperature, humidity, etc. Therefore, this study aims to determine the percentage of dead individuals to the total number of individuals found, as well as to observe the risk factors that cause tree damage and mortality in the Sumber Pawon Forest, Kediri which is empowered as a water conservation area. Observations were made based on the Tree Mortality and Damage Protocol issued by ForestGEO, by observing the stand mode, crown illumination, liana infestation and the presence of fungi affecting tree wood. The results obtained showed that from a total 170 found, 6.47% of individual trees were damaged and died. Of the total 11 trees that died, 6 of them died in uprooted mode (U) and the remaining 5 died in broken mode (B). The process of tree damage and mortality that occurs episodically is thought to be caused by biotic factors such as lianas and fungi, and abiotic factors such as changes in weather, texture and soil moisture.
