| dc.description | The plant Páramo grasslands ecosystem characterization was carried out by means of field expeditions to eight protected areas that Ecuador maintains through the Ministry of Environment. The expeditions were carried out every two months during three years, to evaluate in situ the botanical composition, frequency, density, height, basal cover and aerial cover. The observations were registered during two periods per year, at 60, 90, 120, 150 and 180 d, for a total of 36 evaluations in each study place. The soil pH varied between 5.0 and 8.5, it is volcanic, with sandy and loamy characteristics. The identified species in the Ecuadorians heathlands were: 169 plants with forage importance, 90 grasses, 14 legumes, 28 compounds and 37 belonging to Equitaceas, Oxalidaceas, Liliaceas, Scrophulariaceas, Rosaceas, Ciperaceas, Poligonaceas, Plantaginaceas, Arbustivas, Orchideaceas, Ranunculaceas and Gentianaceas. A total of eighteen species showed good performance, when locating, at least, in a place. Those of great persistence and adaptation were Agrostis breviculmis, Agrostis exigua, Arrhenatherum pratensis, Arrhenatherum elatius, Bromus lanatus, Bouteloua curtipendula, Calamagrostis bolanderi, Calamagrostis tarmensis, Digitaria floridona, Eragrostis curvula, Euchlaena mexicana, Festuca weberbaueri, Holcus lanatus, Paspalum plicatulum, Paspalum bomplandianum, Poa pratensis, Stipa plumeris and Stipa plumosa. For the production of green and dry forage, respectively, the best were Euchlaena mexicana, with 25.9 and 6.7 t/ha/cut, and Arrhenatherum elatius, with 24.4 and 6.9 t/ha/cut; also Arrhenatherum pratense, with 23.0 and 6.1 t/ha/cut and Stipa plumeris, with 21.9 and 6.8 t/ha/cut. There was great plants biodiversity that can be use for animal feeding, which is observed from other studies of chemical composition and management. | |
