Campaña verano 2015. Resumen Ejecutivo RESUMEN EJECUTIVO La flora y vegetación del área Laguna Conchalí fue monitoreada en la temporada de verano 2015. Se determinó la riqueza florística y cobertura de vegetación, además de la cobertura, estado fenológico y fitosanitario de las especies de acuerdo a la metodología propuesta. En el sector se encontraron 31 especies de plantas vasculares. Según lo revisado en los Decretos Supremos que oficializan los procesos de clasificación de especies, y en el Libro Rojo de la Flora Terrestre de Chile (Benoit, 1989), sólo la especie nativa Equisetum giganteum está clasificada, en categoría Preocupación Menor a nivel nacional (DS N° 13/2013 del MMA). La cobertura de la vegetación alcanzó un valor promedio del 100%, siendo Sarcocornia fruticosa, Distichlis spicata y la especie introducida Mentha citrata las especies con mayor cobertura en los transectos muestreados. El parámetro riqueza se encuentra bajo los rangos históricos de especies, por el contrario la cobertura monitoreada presenta rasgos por sobre los monitoreados para el presente monitoreo de verano 2015. No se observaron diferencias significativas en la riqueza de especies ni en la cobertura entre las campañas de verano en el período 2008-2015. Mediante el uso de la herramienta de teledetección fue posible establecer diferencias, en términos espaciales, de la respuesta espectral de la vegetación existente en Laguna Conchalí. En términos espaciales se pudo apreciar, en base al índice NDVI705 que la vigorosidad fue de más de un 85% de la superficie y se sitúa con valores de NDVI entre 0,2 y 0,5. En general, este índice demuestra un estado constante de vigor en relación a los otros períodos (marzo 2013 y 2014) con una concentración en el aumento de este índice en zonas norte (desembocadura del estero Pupío) y centro- poniente del cuerpo de agua principal, lo que indicaría condiciones, tanto de suelo como hídricas, para un desarrollo adecuado de la vegetación existente en el sector. Un 56% de la superficie presenta índices de vigor entre 0,2 y 0,4, mientras que los resultados de detección de cambios demuestran que un 11% de la superficie aumentó su índice entre el 2014 y 2015, un 10% disminuyó su vitalidad. La mayor superficie de estudio no ha presentado cambios positivos ni desfavorables de este índice. Sin embargo, se recalca que según monitoreos previos de las especies, los cambios de la dinámica de barrera y la disminución de caudal en el estero Pupío, podrían generar alteraciones en la distribución de especies y el estado de sus índices.

Introducción 1 INTRODUCCIÓN El Programa de Monitoreo Ambiental asociado a la componente ambiental Flora y Vegetación, está orientado a identificar la ocurrencia de los potenciales impactos y evaluar la efectividad de las medidas de mitigación en área de influencia directa e indirecta por parte de Minera Los Pelambres, derivadas de la implementación de los distintos proyectos que se han llevado a cabo. Las características técnicas del monitoreo han sido definidas en la Resolución Exenta N°71/1997 considerando 8.8 donde se establecen los parámetros, sitios de monitoreo, frecuencias y metodologías, Resolución Exenta Nº83/1998 considerando 7.2 donde se establece que “el plan de monitoreo de flora y vegetación se enmarcará dentro de los planes de monitoreo del E.I.A. del proyecto "Expansión Minera Los Pelambres 85.000 tpd”, y considera toda el área Punta Chungo y la Laguna Conchalí”, y la Resolución Exenta N°38/2004 (ICE páginas 91 a 116) considerando 28 donde se establece “que sin perjuicio de lo anterior, la calificación ambiental del proyecto está sujeta a la exigencia de presentar a la Comisión un documento consolidado y autosuficiente que abarque todos los compromisos de seguimiento y monitoreo, el que se denominará “Plan Integral de Seguimiento y Monitoreo”. Dicho Plan deberá presentar para cada monitoreo o seguimiento los criterios de evaluación, el calendario de la ejecución y una simbología u nomenclatura única y corregida para los puntos de monitoreo”. Este Plan fue aprobado mediante carta N°140 del 23 de abril de 2013, del Servicio de Evaluación Ambiental de Coquimbo. Los alcances sistematizados están contenidos en el Plan Integral de Minera Los Pelambres, el que incluye la componente Flora y Vegetación y parámetros tales como riqueza florística, cobertura (relativa y total), fenología y estado fitosanitario de las formaciones vegetales. De forma complementaria, se realiza una evaluación de la condición de la vegetación mediante imágenes hiperespectrales en el área y/o sector Laguna Conchalí. La zona de monitoreo corresponde al sector Laguna Conchalí considerada Santuario de la Naturaleza y Sitio Ramsar. Este sector registra la condición de humedal costero con dinámica asociadas a intrusión salina cada cierta temporada, y se caracteriza por ser un ecosistema heterogéneo de gran valor ecológico dentro de la Región de Coquimbo. Adicionalmente, a un costado del humedal se desarrollan las actividades de separación, almacenaje y carguío de concentrado y disipación de aguas efluentes, siendo sus principales el estero Pupío y Conchalí.

  • "National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary."
    Intro 1996 National List of Vascular Plant Species That Occur in Wetlands The Fish and Wildlife Service has prepared a National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary (1996 National List). The 1996 National List is a draft revision of the National List of Plant Species That Occur in Wetlands: 1988 National Summary (Reed 1988) (1988 National List). The 1996 National List is provided to encourage additional public review and comments on the draft regional wetland indicator assignments. The 1996 National List reflects a significant amount of new information that has become available since 1988 on the wetland affinity of vascular plants. This new information has resulted from the extensive use of the 1988 National List in the field by individuals involved in wetland and other resource inventories, wetland identification and delineation, and wetland research. Interim Regional Interagency Review Panel (Regional Panel) changes in indicator status as well as additions and deletions to the 1988 National List were documented in Regional supplements. The National List was originally developed as an appendix to the Classification of Wetlands and Deepwater Habitats of the United States (Cowardin et al.1979) to aid in the consistent application of this classification system for wetlands in the field.. The 1996 National List also was developed to aid in determining the presence of hydrophytic vegetation in the Clean Water Act Section 404 wetland regulatory program and in the implementation of the swampbuster provisions of the Food Security Act. While not required by law or regulation, the Fish and Wildlife Service is making the 1996 National List available for review and comment.

The lakes studied (Tinquilco, Verde, Toro, Chico) are located in the Huerquehue National Park (39°08’S, 71°40’W), Chile. An inventory of the aquatic and riparian species was performed between December 2005 and March 2006. A null model analysis was done to determine the existence of regulatory factors of species associations, and the Jaccard index was applied to determine floristic similarities. Seventy- five species were identified. The greatest number (54) and highest percentage of introduced species (37%) occurred at Tinquilco Lake, placing it in the category of “high human disturbance”.

Leishman1 1Department of Biological Sciences, Macquarie University Correspondence: Guyo D. Gufu, Department of Biological Sciences, Macquarie University, NSW 2109, AUSTRALIA. E-mail: [email protected] Abstract: Freshwater systems are considered particularly vulnerable to human impact, through habitat modification, changes to water regimes and quality, invasion by exotic species and climate change. Using various records, we conducted a descriptive analysis of the naturalised freshwater plant species in Australia. There are 63 freshwater plant species belonging to 45 genera and 26 families naturalised in Australia with the dominant families being Cyperaceae, Poaceae and Plantaginaceae. More than 40% of these species are categorised as either invasive or declared weeds, the majority being perennial wetland marginal plants. They originated from all the inhabited continents with most of the species being native to Europe, South America and North America. The greatest number of species are currently found in New South Wales (90%), Queensland (68%) and Victoria (65%); the ornamental aquarium plant trade was identified as the main introduction pathway. Most species are clonal plants with flexible modes of reproduction and multiple dispersal vectors. We conclude that exotic plant species are now an important component of Australia’s freshwater systems and that ongoing monitoring of their status, distribution and impact should be a high priority in light of the increasing influence of anthropogenic factors including climate change.

  • Diversidad, Hábito Y Hábitat De Macrófitos Acuáticos En La Patagonia Occidental (Región De Aisén, Chile)
    Anales Instituto Patagonia (Chile), 2011. 39(1):23-41 23 DIVERSIDAD, HÁBITO Y HÁBITAT DE MACRÓFITOS ACUÁTICOS EN LA PATAGONIA OCCIDENTAL (REGIÓN DE AISÉN, CHILE) DIVERSITY, HABIT AND HABITAT OF AQUATIC VASCULAR MACROPHYTES OF THE WESTERN PATAGONIA (AISÉN REGION, CHILE) Cristina San Martín1, Yessica Pérez1, Drina Montenegro1 & Miguel Álvarez2 ABSTRACT We studied the abundance, phytogeographycal origin, biological spectrum and the habitats of the aquatic macrophyte flora in the limnic (lotic and lentic) wetlands and in salt marshes of the Aisén Region, Chile. We found 86 species of vascular macrophytes including in 54 genera and 33 families. Only 8 species are abundant (Myriophyllum quitense, Potamogeton stenostachys, Glyceria multiflora, Hippuris vulgaris, Marsippospermum grandiflorum, Tetroncion magellanicum, Scirpus californicus and Gunnera magellanica), most of them occurring in swampy habitats from the river banks. Of the total species num- ber, 73 are native and 13 introduced, indicating little human disturbance in those wetlands. The biological spectrum consists of 54 perennial herbs (hemicryptophytes) and 23 tall herbs with underwater rhizomes and aerial culms (cryptophytes). The tall perennial herbs (chamaephytes) are represented by 6 species and the annuals (therophytes) by 3. Sixty seven swampy emergent forms (helophytic) and 19 species of aquatic plants (submerged, with floating leaves and free floating hydrophytes) were collected. The wetlands with higher species richness were the lowland ponds with 44 species and streams with 37 species. Small stands of coastal marshes were the only brackish habitat studied here, containing 5 halophytes (Cotula coronopifolia, Puccinellia glaucescens, Triglochin concinna, Ruppia filifolia y Zannichellia palustris). We analyzed the historical development of the knowledge of the aquatic macrophytes in the Aisén Region, concluding that the most of the species had been prospected before.

Introduction Chile has a National System for State-Protected Wilderness Areas (Sistema Nacional de Áreas Silvestres Protegidas del Estado – SNASPE), which consists of three categories: National Parks (PN), National Reserves (RN) and Natural Monuments (MN). It presently contains 95 units, covering in total 19% of the country's territory. SNASPE has become a fundamental pillar not only for safeguarding an important part of Chile's natural heritage but also for protecting and valuing our cultural heritage, particularly where it is integrated in the areas which make up this system (Oltremari, 2002). By 1985, UNESCO had designated 7 Biosphere Reserves in Chile: Lauca, Fray Jorge, Juan Fernández, La Campana-Peñuelas, Araucarias, Laguna San Rafael and Torres del Paine. To these were later added Cabo de Hornos [Cape Horn], Bosques Templados Lluviosos de los Andes [Wet Temperate Andean Forests], and recently Laguna del Laja-Nevados de Chillán.
