Kajian lahan dilakukan antara lain tata guna, kelas kemampuan, konsep pengelolaan, kesesuaian lahan, dan penentuan vegetasinya. Hasil identifikasi sumber mata air menunjukkan bahwa terdapat 3 lokasi yang potensial dibangun arboretum, yaitu Desa data kualitas tanah, ketiga lokasi memiliki media perakaran yang cukup baik untuk tanaman budi daya. Secara umum, semua jenis tanaman budi daya sesuai untuk ditanam di ketiga lokasi arboretum. Perlu dilakukan pembuatan teras dan penerapan pola tanam konservasi yang mengaplikasikan tanaman penutup tanah (cover crop), tanaman budi daya, dan pohon penyusun hutan. Selain itu, perlu pemberian pupuk organik berupa kompos dan pupuk kandang.
