Biodiversity in tropical plantations is influenced by surrounding native vegetation but not yield: A case study with dung beetles in Amazonia

ABSTRACT The new Brazilian Forest Code (Laws no. 12,651/2012 and no. 12,727/2012) establishes a set of rules in relation to native vegetation areas, such as Permanent Preservation Areas and 'Legal Reserve', that must be preserved by the landowner. Thus, it becomes relevant to survey these areas, as well as to assess the need for recovering them. In this context, this research aimed to propose a method for calculating the Native Vegetation Recovering Index (NVRI) for rural properties and to validate it on a case study of Porto Alegre/RS drawing on geotechnology and on a technical cadaster. The method enabled to assess the range of native vegetation and to characterize the Permanent Preservation Areas and the Legal Reserve of rural property, as well as to estimate the fraction of the area to be recovered with native vegetation in each property. In the case study, the calculated NVRI was null for 61 properties, and ranged from 0.1% to 94.0% for other 15 properties examined. For properties sized up to 01FM (one fiscal module), the NVRI was 1.3%; for those sized between 01 and 02FM, it was zero; for properties sized between 02 and 04FM, NVRI was 1.5%; and for properties above 04FM, it was 10.8%. For the total surveyed properties, the calculated NVRI showed that 9.2% of the area that should be covered with native vegetation is in need to be recovered, since it is disfigured in terms of its native flora. By enabling to assess the situation of each rural property regarding its compliance with guidelines established in the new Forest Code, the applied method becomes a supporting tool for policies on territorial and environmental management.

Abstract To evaluate the feasibility of reintroduction as a tool for conservation of the jaguar Panthera onca, we adapted the IUCN soft release protocol to reintroduce two jaguars in the southern Pantanal, Brazil. After being kept at rescue centres for 13 months, the jaguars were moved to a 1-ha enclosure with native vegetation on a 53,000 ha ranch in the Pantanal, where hunting is not allowed and prey is abundant. In the enclosure, the animals were fed with meat, dead animals (roadkill) and then, progressively, live wild prey. After 11 months, the jaguars were fitted with collars equipped with GPS/VHF (recording one location per hour) and accelerometers, and released in the same area. The animals established residence near the enclosure, with home ranges, movement parameters, daily activity patterns and prey consumption similar to that recorded in previous studies. Social interaction and reproduction indicated the reintroduction was successful, and that it can be a tool for the species' survival in areas where the jaguar population is in decline.

Conservation And Management

Woopenatty was a 7,293 ha wheat-sheep property in the Geraldton Sandplains biogeographic region of the northern wheatbelt of Western Australia. Data were collected on the presence of bird species seen on a weekly basis on the property from October 1987 until the end of 2002. A total of 133 species was recorded from the property during this period with 52 species of resident, 16 species of regular visitor, 15 species of irregular visitor and 50 vagrant species. The avifauna of the property was compared with records collated from 1904 from eight locations within a radius of 110 km of the property and from records within a radius of 50 km of the property from two Birds Australia atlases (1977– 1981 and 1997–2002). Seventy-four percent of the species, including many dependent on remnant native vegetation, recorded from the other localities were recorded on Woopenatty. The property was clearly of importance for conservation of the avifauna of the Geraldton Sandplains. This study illustrates the importance of publishing descriptions of regional biota in order to assess changes over time and the significance of remnant native vegetation on private property to conservation. Suggestions for setting priorities for conservation and management of such remnant native vegetation are made.

ABSTRACT Identifying threats and their regional occurrence across a species’ range is increasingly valuable for prioritising threat-specific interventions and achieving effective conservation outcomes. We surveyed registered wildlife rehabilitators to identify (i) threats faced by the koala across Victoria and (ii) their perceptions on koala population trends and potential threat mitigation actions. Wildlife rehabilitators identified habitat loss, fragmentation, and degradation as the biggest threat to koalas, while vehicle collisions, heatwaves and wildfire were also identified as key threats. Accordingly, reducing the clearing of native vegetation was considered the most effective threat mitigation action, while creating of wildlife corridors, planting of more food trees, and educating communities living in koala occupied areas were also considered appropriate mitigation strategies. Finally, 89% of wildlife rehabilitators believed that koala numbers are declining in their region.
