DIVERSITY, ESTRUCTURE AND RICHNESS INDICATORS FOR THE CONSERVATION OF VEGETATION BIODIVERSITY IN RURAL LANDSCAPES

Abstract

The lack of efficient sampling techniques for the study of linear vegetation remnants in the Mexican tropics anthropised areas was the main premise for this research, in order to determine the diversity, richness and vegetation structure of rural landscapes according to its conservation value through efficient and representative linear sampling techniques. The biological characterization of plants was performed in an area of 4,096 m2, in eight components of the landscape, a total of 2260 ha. The vegetation consists of 144 species, 127 genera and 51 families. These were distributed at herbs 71.26%, shrubs 22.80%, trees 3.49%, and vines 2.45%. High values ​​of diversity and richness were found in hedgerows, stream shore, shore road, scrub and citrus growing. It is suggested to give priority to the conservation of stream bank that protects species such as Cedrela odorata and Sapium macrocarpum. The efficiency and representativeness of the sample was 95% through rarefaction given by the best fit of Chao 1 and ACE, highly significant linear correlation between true diversity and richness of species, and the high value of spare.
