Abstract


This is the first report on grassland primary productivity for the wildlife protected area Nevado de Toluca (APFF Nevado de Toluca). We evaluated three communities in this area during dry season: Loma Alta, La Peñuela y Agua Blanca. Following Hodgson (1994), for this study we used exclusion cages. Vegetation was cut every 28 days during a five months sampling period. A randomized block design was used, where the blocks represented the grassland communities and the different months constituted treatments. The month of September showed the higher production (610.3 kg/ha DM). No significant differences were observed among communities (P >0.05). In conclusion, these communities have similar low primary productivity through the evaluation dry season months, which in addition was found lower in comparison to other areas, therefore livestock grazing in this region should be limited this season.
