Contributions of Corporate Green Space in Conserving Plant Diversity and Its Potential Usefulness: Case Study Wikasatrian Pusat Kepemimpinan

Abstract

Wikasatrian Pusat Kepemimpinan, under the PT Wijaya Karya Persero Tbk management, applies sustainability principles in managing its landscape. Wikasatrian Forest is a green-forested space in the Wikasatrian that is allowed to grow and develop naturally with no or lesser management. A study on plant diversity was conducted to strengthen its conservation value. The study aimed to identify the plant variety of the Wikasatrian Forest, assess the population, and its potential usefulness for people and nature in the landscape and other needs. Data were collected using the line transect method and quadrats analysis of 10 x 10 m squares for trees, 5 x 5 m squares for saplings, and 1 x 1 m squares for ground covers, with six plots of 10 x 100 m squares, in line with the forest track. Results showed that 26 tree species from 20 families were found. On all structure levels, the Shannon's diversity index (H) was moderate (2.53 - 2.78), and the species evenness index (E) was high (0.7 - 0.82). These showed that this area has a good ecosystem balance with diverse plant species. Most species have multiple potential uses, which are used for medicinal purposes (14) and food sources (10). Some are for materials (9) and environmental improvement (6).
