Distribución de plantas vasculares a escala local. Taxones con mayor ocupación geográfica en ambite y utande (la alcarria occidental)

Abstract

The method for performing Floral Cover Indices (FCI), presented in a previous article, is applied to two 100 km2 U.T.M. grid cells (30TVK86, Ambite and 30TWL02,Utande). They are located in different sectors of the natural region of Western "La Alcarria". The goal is to know and compare distributions of presence and abundance of vascular plants at local scale. Geographical factors affecting cover of the flora is widely exposed. Analysis method and chorological maps drawing with four spatial levels (1, 4, 25 and 100 km 2) are presented. Results of the twelve taxa with the highest FCI in the set of two grid cells and phytogeographical interpretations are shown: Genista scorpius, Quercus ilex subsp. ballota, Thymus vulgaris, Helianthemum cinereum subsp. rotundifolium, Brachypodium retusum, Thymus zygis subsp. sylvestris, Lavandula latifolia, Dactylis hispanica, Rosmarinus officinalis, Koeleria vallesiana, Quercus faginea and Salvia lavandulifolia.
