Change in the protection regime of Permanent Preservation Areas in the 2012 Forest Code

Abstract The parameter for delimiting Areas of Permanent Preservation (APPs) in the 2012 Forest Code is the edge of the regular stream bed, not its highest level. The objective of this study is to evaluate the loss of protected areas, framed the category of water APPs in the 2012 Forest Code, in the Cabaçal River. By means of spatial technologies, maps of vegetation cover and land use from 2012 and 2018 were prepared. The change in the Forest Code in 2012 caused the loss of 90% of the area previously protected by the 1965 Code, corresponding to the major waterbed of the Cabaçal River, especially in the lower course, located in the Pantanal plain of Mato Grosso. It was concluded that the vegetation cover in the Areas of Permanent Preservation was suppressed so that urban and agricultural uses could be implanted, characterizing them as conflict areas due to the flexibilization of the environmental legislation

Tree diversity assessment in paraguay river islands, between caceres and ecological station taiamã, pantanal, brazil

Several studies have evaluated the mechanisms that determine the different landscapes in the Pantanal, there are multiple factors that are working together on the islands of the Pantanal contributing to the maintenance of its current state. Surveys have been conducted on six islands in the river between Paraguay and Cáceres Taiamã Ecological Station, Pantanal, comparing the diversity of islands from two geomorphological processes: from the rupture of the neck of meander and sedimentation. This study aimed to determine the effects of soil characteristics and flood levels in tree diversity. The samples consisted of 22 plots per island of 10m by 20m down the center and edge, and depositional and eroded sides of the islands. The topographical differences between the plots were measured from the River. We recorded 40 species belonging to 34 genera and 21 families. The indices of Shannon- Weaver diversity ranged from H 'from 1.08 to 2.77. The floristic communities were distinct between the islands of different origins, which are subjected to different periods of flooding. The islands formed by breaking the neck of meander abundace and have higher species richness. The soils of the islands, had an average of clayey to very clayey. The group formed by the most frequent and abundant species in the islands were positively correlated with soil properties that were high on the islands, such as magnesium and saturation of magnesium, and aluminum, clay and silte.O center of the islands is subject to a period of more flooding . There were differences in height between local depositional and erosion occurred in five islands, and the erosional side is higher than the depositionDiversos estudos têm avaliado os mecanismos que determinam as diferentes paisagens no Pantanal, são múltiplos os fatores que estão atuando conjuntamente nas ilhas do Pantanal contribuindo para a manutenção do seu estado atual. Foram realizados levantamentos em seis ilhas do rio Paraguai entre Cáceres e Estação Ecológica de Taiamã, Pantanal Matogrossense, comparando a diversidade de ilhas originárias de dois processos geomorfológicos: a partir do rompimento do colo do meandro e de sedimentação. Este estudo teve o objetivo de determinar os efeitos das características dos solos e níveis de inundação na diversidade arbórea. A amostragem foi de 22 parcelas por ilha de 10m por 20m estabelecidas no centro e borda e lados erosionais e deposicionais das ilhas. As diferenças topográficas entre as parcelas foram medidas a partir do rio. Foram registradas 40 espécies pertencentes a 34 gêneros e 21 famílias. Os Índices de Diversidade de Shannon-Weaver variaram de H 1,08 a 2,77. As comunidades florísticas foram distintas entre as ilhas de diferentes origens, que estão submetidas a diferentes períodos de inundação. As ilhas formadas por rompimento de colo de meandro possuem maior abundacia e riqueza de espécies. Os solos das ilhas, apresentaram em média textura argilosa a muito argilosa. O grupo formado pelas espécies mais freqüentes e abundantes nas ilhas correlacionaram positivamente com atributos do solo que nas ilhas apresentaram altos valores, como magnésio e saturação por magnésio, alumínio trocável, argila e silte.O centro das ilhas está sujeito a um período de maior inundação. Houve diferenças de altura entre locais deposicionais e erosionais ocorreram em cinco ilhas, sendo que o lado erosional é mais alto que o deposicional

Biodiversity and its drivers and pressures of change in the wetlands of the Upper Paraguay–Guaporé Ecotone, Mato Grosso (Brazil)

The biogeographic regions Amazonia and the Pantanal, two areas of high biodiversity importance, have a link to each other through an ecotone formed by the upstream part of the rivers Paraguay and Guaporé. The two river basins share part of their flora and fauna species and in this ecotone species exchange processes takes place. Therefore it should be considered as an important area to realize the targets for2020 of the Convention of Biological Diversity (CBD) at the regional level. However, since over 20 years this area is under severe pressure of land conversion and is increasingly threatened by river change, due to building of hydroelectric power stations. This causes direct and indirect damaging effects on the region and on its role as biodiversity corridor. In the framework of the BioNorte project we carried out a Driver,Pressure, State, Impact, Response (DPSIR) analysis of the region and included a stakeholder analysis. The direct pressures are changes in the use of land and rivers that constitute the river ecotone between the Amazon and Pantanal. Indirect pressures are road access, opening the land for further deforestation and agricultural developments. Fragmentation of the remnant forest patches in combination with river fragmentation can cause decline in biodiversity, prevent species exchange between the Amazonia and the Pantanal and fish to spawn upstream. If river flows are being blocked, the flood pulse and the migration corridor of fish and the transport of plant seeds will be hampered. The societal response to this can be denial, a positive reaction by enforcement of traditional conservation actions or, as agreed at the COP2010 by the Convention of Parties to the CBD as a goal for the year 2020, the integration of biodiversity targets into land development toward sustainable land use by diminishing river and forest fragmentation

Birds of the Ramsar site Estação Ecológica de Taiamã and buffer zone, Pantanal wetlands, Brazil

The Estação Ecológica de Taiamã (EET) is one of the Ramsar sites in the Pantanal wetlands of Brazil. We present an annotated list of bird species recorded between 2015 and 2018, along with a compilation of existing data for this area. In our sampling, 207 species were recorded, with 76% documented. We have the first record of Chlidonias niger (Linnaeus, 1758) for the Pantanal and Central region of Brazil. Another 30 species are new records for EET, such as the migrant Hirundo rustica Linnaeus, 1758. The general list comprises 24 orders, 60 families, and 278 species, of which 160 were assigned to the primary list and 118 to the secondary list. This study will aid in the conservation of biodiversity in the Pantanal. The EET and its buffer zone are important for maintaining biodiversity and expanding its boundaries may further promote the conservation of birds in Brazilian wetlands
