Abstract

Vegetable fern (Diplazium esculentum) is a fern widely used as a food source and plays an ecological role in maintaining soil moisture and preventing soil erosion. This research aims to analyze the population of vegetable ferns under forest garden stands. The research was conducted from September to October 2025 at forest farmer's cultivated area plot number 4, one of the plots cultivated by forest farmers members of the Harapan Baru Forest Farmers Group Alliances (FFGA) in the Wan Abdul Rachman Grand Forest Park. The data was collected through vegetation surveys using nested rectangular plots that arranged systematically with a sampling intensity of 2.8%. The data collected includes the species of trees as components of forest garden stands and the number of individuals for each species, the number of individual vegetable ferns, and the environmental conditions of the habitat (including solar radiation intensity, air temperature, air humidity, and altitude). Data were analyzed by calculating density (D) and Ochiai index (OI) at 5% significance level. The results showed that the composition of forest garden stands consisted of 14 tree and shrub species with a total density of 1,997.5 individuals/ha. The population density of vegetable fern varied between plots (0-20 individuals/plot) with an average of 9.6 individuals/plot or 2.4 individuals/m 2. Vegetable fern lived under the shade of avocado, durian, candlenut, and stink bean trees, with air temperature conditions of 27-33 oC, air humidity of 55-77%, solar radiation of 407-1,687 lux, and altitude of 360-508 m above sea level. The OI between vegetable fern and avocado trees was 0.73; with durian trees 0.73; with candlenut trees 0.67; and with stink bean trees 0.50. The association between vegetable fern and these shade trees was not statistically significant (χ²corrected< 3.84).
