- Forest is a natural resource, an ecosystem in where happened an equal relationship between species and its environment. Environment where the plant grew is a complex system, where all factors interacting each other and has equal influence direct or indirect to the plants society. All organism and its environment has dynamic attitude, which means that among them always interaction which created changes. The research aimed to find out about various construction structure and vegetation composition in Natural Construction Forest vegetation Natural Park of Tengger Semeru Ireng-Ireng Blok, finding the forest community pattern and the community relation pattern with their environment, also finding the various level of trees lifetime in the region of Forst vegetation Natural Park of Tengger Semeru Ireng-Ireng Blok. Method used in the research was line method to do vegetation analysis in Ireng-Ireng Blok region. As the existing research, National Park of Bromo Tengger Semeru was one of conservation region which should be maintained by better processing for its plasm nutfah, so that it could be benefit for the life line. Ireng-Ireng blok is a region in National Park of Bromo Tengger Semeru with ± 485 ha region in Lumajang residence and became natural forest which owed various vegetation 198 amount with 64 famili spreaded and various in every measurement box. For the research, the dominant kind for trees level was Bischofia javanica with important value 16,7324 and density value 7 and then Celtis wightii with important value 11,3913 and density 6 while Ficus virens with important value 11.0923 with density 6, which means for each vegetation level was so various as told in discussion table 4.4;4.5;4.6 and the spreading could be seen in attachment 2a, 2b, 2c, 2d. For the dominant pole for Ireng-Ireng blok was Macaranga sp. With important value 21,9117 with density 20 then followed by Erythrina subumbans, Ficus sp dan Aglaia sp with all important values 21,9117; 19,7639; 19,0506; 18,1632 and density 20; 16 ;16; 16 so that further influence covering the other vegetation for pole level and rule their environment. In this region, sampling level which dominated was Talauma candollii vegetation for gift 34,5535 and 156 density the next was Quercus elegans and Antidesma bunius with important value for Quercus elegans was 26,6632 and density 56 while for Antidesma bunius owed important value 20,8588 and the density 120. While for down plant dominated by imperata cylindrical amounted 434 in all over measurement day so that it could be closing in vegetation kind for another compenssation.sehingga menjadi penutup bagi jenis vegetasi tumbuhan bawah yang lain. Vegetation structure in the region was various. It was caused by the dominant level of vegation, and it was caused by the director Vegetation structure in Ireng-Ireng was various. It caused by each vegetation level dominant in vegetation structure like Bischofia javanica, Celtis wightii, Ficus virens, Macaranga sp, Erythrina subumbans, Ficus sp, Aglaia sp, Talauma candollii, Quercus elegans, Antidesma bunius the spread became the major factor outside the flat Ireng-Ireng blog tophography.
