The university owns one hundred and sixty (160) acres of land area with the forest pocket (25 acres) and two minor tanks (Saalampaikulam and Velan Kulam). Salampaikulam is situated between the university residential area and the academic area. It helps to maximise the biodiversity of flora and fauna and makes the premise environmentally friendly. The university premise consists of more than 2500 trees (65 species) except for the forest pocket. It helps to embrace nature, celebrate the seasons with its beauty, and involve the students and staff in their studies and hobbies (projects, photography, bird watching, etc.). 

Landscaping is a creative and deeply satisfying experience. It is important to add landscape features with the basic landscape principles. A garden or a land can be made more attractive by altering the existing design, adding ornamental features, and planting trees and shrubs. Indoor and outdoor landscape gardening helps to involve the staff and students in recreational activities.

The person, group of people, or organisation can donate the fund or goods for the development of the landscape and green environment of the University of Vavuniya.
