State Of The Environment

Despite the fact that the most changes in lists of threatened species reflect changes in knowledge rather than changes in conservation status, the lists continue to provide social and legal mandates for conservation; they are used to report on the state of the environment and to guide the allocation of scarce resources. There is a substantial under-representation of non-vascular species in threatened plant lists, reflected in an absence of documented extinctions among fungi and algae. Turnover in the composition of extinct flora lists in Australia suggests that the lists of threatened species may not be sufficiently reliable to form the basis for reporting on the state of the environment. They are of limited use in distinguishing between levels of threat and may not be a reliable guide for the allocation of scarce conservation resources among plant species. Systems for listing threatened species create a feedback loop, responsive to the subjective preferences of scientists, largely unresponsive to underlying true threats, self-perpetuating and accentuating bias with each iteration. Other tools, including formal decision approaches and the acquisition of new kinds of data, are needed to fill the roles.

Abstract Brazil is signatory of the Global Strategy for Plant Conservation (GSPC), which provides guidelines and directions to existing national policies. This strategy aims to halt the continuing loss of plant diversity through the achievement of 16 outcome-based targets set for 2020. One of these targets (target 7) states that at least 75% of known threatened plant species should be preserved in situ. Here, we assessed the effectiveness of the Brazilian current network of protected areas (PAs) and indigenous lands (ILs) in representing all known threatened plant species. We found that the number of species represented inside PAs and ILs varied according to data type. When using occurrence records, we found that 699 (33%) threatened plant species lie completely outside PAs (and/or ILs) and that 1,405 species (67%) have at least one record inside at least one PA (and/or IL). The number of species unrepresented decreased when we considered polygons of distribution. In this case, only 219 (10%) are supposedly unprotected. Although Brazil is almost reaching GSPC Target 7 in terms of absolute numbers, the government still needs to allocate resources for properly managing and improving the conservation status of its imperiled flora and expand the network of PAs.

There have been some studies on the plant species found in Mindoro, Philippines, but there remains little information in their status particularly at the local level. This paper presents a list of threatened plant species of Mindoro. A list of indicators of the conservation status was formulated for this particular study and was used for categorizing the threatened plant species at the local level. The list recorded 173 threatened plant species from 70 plant families, which are composed of 25 Critically Endangered (CR), 46 Endangered (EN) and 102 Vulnerable (VU) plant species. The species were found to be threatened because of their endemicity, as well as some anthropogenic activities that could lead to the destruction of their habitats and ultimately, their extinction. There are still existing gaps in the knowledge of the flora of Mindoro, and when these gaps are addressed, it is possible that more rare and threatened plants will be added to the list. It is also recommended to utilize the data in the enactment of the laws to address the threats to plant biodiversity loss. Keywords - Botany, threatened plant species, Mindoro, conservation status, International Union for the Conservation of Nature (IUCN), Department of Environment and Natural Resources (DENR), Mindoro, Philippines
