Pertumbuhan penduduk yang tinggi menyebabkan kebutuhan kayu semakin meningkat, baik kayu perkakas maupun kayu bakar. Wana sebagai pemasok kebutuhan bahan baku kayu perkakas/kayu pertukangan. Wana diharapkan memberikan nilai positif dalam hal ketahanan pangan bagi masyarakat di Dusun Dengok VI. Penelitian ini bertujuan untuk mengetahui struktur, komposisi dan pemanfaatan tanaman jenis pada wana. Penelitian ini dilakukan pada wana sempit dengan luas 1.000-2.000 m2, dan wana luas dengan luas 2.000 m2 pada masing-masing 3 wana. Untuk menjawab tujuan tersebut dilakukan 3 metode pendekatan, yaitu: (1) Analisis vegetasi untuk mengetahui kerapatan dan dominasi jenis (2) Ruang Vertikal (RV) dan Ruang Horizontal (RH) dengan menggunakan pendekatan spasial dan tiga dimensi SExI-FS (3) Pemanfaatan tanaman jenis wana berdasarkan wawancara. Pengambilan data dalam sampel wana dilakukan dengan Intensitas Sampling (IS) 100%. Berdasarkan hasil penelitian, menunjukkan struktur horizontal wana sempit didominasi jati (2,47 m2), trembesi (0,67 m2) dan wana luas didominasi oleh jati (2,22 m2). Struktur vertikal wana sempit didominasi oleh stratum C dan wana luas oleh stratum C. Komposisi jenis tanaman penyusun wana diketahui berdasarkan nilai INP. Tingkat semai pada wana sempit didominasi oleh jati (53,47 %), wana luas didominasi oleh jati, kupu-kupu, mahoni, mangium dan lamtoro (20%); tingkat sapihan pada wana sempit didominasi oleh jati (90,59%), wana luas didominasi oleh jati (60,71%); tingkat tiang pada wana sempit didominasi jati (171,74%), wana luas (126,04%); tingkat pohon pada wana sempit didominasi jati (189,93%), wana luas (136,96%). Pemanfaatan tanaman jenis wana didominasi oleh jati dan mahoni pada kategori sempit dan luas. Jati dan mahoni menjadi pilihan utama karena nilai jual yang tinggi dan cocok ditanam serta kayunya dimanfaatkan sebagai bahan bangunan dan sebagai bahan industri perkayuan dan menambah pendapatan serta untuk tabungan di masa mendatang.

High population growth gave effect to increasing of the needs of wood, including wood for utensil or firewood.Wana was serve as suplier of utensil wood raw material.Wanawas expected could gave the positive value in food availability for people in Dengok VI area. The objectives of this research were to know structure, composition, and utilization of wana plant element This research was done in narrow wana with area less than 1000- 2000-2,and large wana with area more than 2000 m2with 3 wana each. The answer of those objectives did by 3 methods, that is: (1) vegetation analize to know density and species domination. (2) Vertical Space (VS) and Horizontal Space (HS) by using spatial approach and three dimention SExI-FS(3) utilization of wana plant element based on interview. Data retreieval in wana sample was did in 100% sampling intensity. Based on this research shows that horizontal structure of mediumwana was dominated by teak (2,47m2), rain tree (0,67 m2) and large wana was dominated by teak (2,22m2). Vertical structure of mediumwana was dominated by C-stratum and large wana by C-stratum too. The composition of wana element plant species was known by INP value. Seedling level in mediumwana was dominated by teak (53,47%), large wana was dominated by teak, kupu-kupu, mahogany, mangium, and white leadtree(20%); sapling level in mediumwana was dominated by teak (90,59%), and large wana was dominated by teak (60,71%); pillar level in mediumwana was dominated by teak (171,74%), large wana (126,04%); tree level in mediumwana was dominated by teak (189,93%), large wana (136,96%). Utilization of wana plantation species was dominated by teak and mahogany in both category narrow and large. Teak and mahogany became the first option because they have high price and appropriated to be planted and the wood were used as building material and raw material of wood industry and increase income and to be saved for the future.
