Abstract

Research on the condition of forest health in forests in the Andalas University campus area or in permanent plots in the Biological Education and Research Forest of Andalas University (HPPB) has been carried out from December 2021 to March 2022 on permanent plots. This study aims to determine the canopy cover and forest health conditions in HPPB permanent plots. This study used a purposive sampling method, in which a photo of crown cover was taken as the center point for each sub-plot measuring 10 x 10 m on the entire permanent plot of 1 ha using the hemispherical photography method. The conclusion of the 100 subplots observed was that 78 subplots had a percentage of canopy cover greater than 65%, indicating that the condition of this forest can be classified as very close. The forest health analysis concluded that the forest health index was 45,22%, indicating that this forest was in moderate condition. Keywords : canopy cover, dbh, forest health index, glama.
