ABSTRACT

Se presentan 61 nuevos registros de plantas introducidas para el Parque Nacional Torres del Paine (49°21’-51°08’S y 73°07’-74°52’O), región de Magallanes, con una superficie de 181.414 ha. Se encontraron 85 especies introducidas, pertenecientes a 21 familias y 65 géneros. Las familias mejor representadas en número de especies fueron Poaceae (22 spp.), Asteraceae (11 ssp.) y Caryophyllaceae (7 ssp.). Las hierbas perennes constituyen el 52% y las anuales el 34% de la flora. El 88% de ellas son de origen europeo y el 36% corresponde a especies invasoras.

    ABSTRACT: Central Chile supports a rich native fora and a high proportion of alien, naturalized plants. To increase our knowledge about behavior of naturalized plants in central Chile, the fora of the western slope of the Coastal Range (Province Valparaiso, 33°S lat.), was recorded and analyzed. Study sites were placed at natural and anthropic, perturbed areas. Taxonomic richness, species composition, geographic origin, Raunkiaer’s life forms, and absolute coverage were recorded. Of the 325 vascular plant species were identifed, 110 (34%) were considered alien; 74% of them with European origin, and 10%, European-North African. According to abundance, 27 % of the plant coverage was of native species and 73% of non-natives. The natives were distributed in 68 families and the naturalized and cultivated in 28 families. Asteraceae, Poaceae y Fabaceae were the richest in both native and naturalized species. The native species were distributed in 146 genera and non natives in 89. Alstroemeria, Baccharis and Calceolaria were the richest in native species; Erodium, Trifolium, Rumex and Vicia, were rich in alien species. Hemicryptophytes and therophytes were most abundant in natives and naturalized species. We conclude that due to increasing urban and agricultural pressures on soils in Province Valparaíso, it is expected that short-lived alien species with opportunistic, high-reproductive capacity, will increase in diversity and abundance.

    ABSTRACT: This study describes the impact of a wildfire caused by a tourist at Torres del Paine Biosphere Reserve in 2005, which destroyed approximately 2,000 ha of forests. Changes on biodiversity attributes of Nothofagus pumilio stands including structure, floristic composition and regeneration, are shown. We compared three plot groups having similar site and structure: Cordón Masle burned plots (CMBP); Cordón Masle unburned plots (CMUP), adjacent to the first ones; and Cerro Paine unburned plots (CPUP), outside the fire perimeter. Data was analyzed using univariate (Mann-Whitney) and multivariate (MRPP and ISA) non-parametric analysis. In CMBP, the fire reduced in average 91.7 % of the tree density and 70.9 % of the basal area. In the unburned plots the average of seedling was 23,625 and 22,750 ha-1 in CPUP and CMUP respectively, whereas in burned ones it was only 1,125 ha-1 in CMBP. Canopy layer collapsed and species richness and cover on ground increased significantly in burned plots. The average of exotics increased from 1.5 and 0.6 in CPUP and CMUP respectively to 11.9 in CMBP. Tree mortality, lower regeneration, biological invasion and broken canopy-ground balance in burned stands, are altering the successional pathways of forests, making difficult the forest regeneration and restoration efforts. Based on this information, we propose managers to encourage efforts in fire prevention and to incorporate a database on biodiversity indicators for management plans, in order to know more about the ecological integrity of ecosystems and the impacts provoked by recreation.

    ABSTRACT: The orchid flora of Torres del Paine Biosphere Reserve (TPBR) is described based on botanical surveys, photographical records and herbarium collections carried out by the authors. This list comprises 3 genera and 9 species: Chloraea chica, Chloraea leptopetala, Chloraea magellanica, Codonorchis lessonii, Gavilea araucana, Gavilea gladysiae, Gavilea littoralis, Gavilea lutea and Gavilea supralabellata. G. gladysiae is a new record for this protected area and the first albino aberrant phenotype for flowers of Chl. magellanica is reported. A description of the species including key for determination, morphology, habitats, local abundances, flowering phenology and photographs is provided. The species richness here reported represents ca. 35% of orchids occurring in the Chilean temperate-austral floristic regions and 75% of the species described for the Magallanes Region, putting the Torres del Paine Biosphere Reserve as one of the most representative protected areas for this taxonomical group in the region. Based on our results we addressed the need of establishing monitoring programs for orchids and promote them as flagship species in ecotourism planning in order to enhance species valuation and encourage biodiversity conservation.
