Abstract. Lillo EP, Malaki AB, Alcazar SMT, Redoblando BR, Diaz JLB, Pinote JP, Rosales R, Buot IE Jr. 2020. Native trees in Nug-as forest Key Biodiversity Area, Cebu, Philippines. Biodiversitas 21: 4162-4167. Threatened species, by definition, have a high probability of extinction, and so each of their populations significantly contributes to their survival. This paper presents a list of threatened Native trees in Nug-as forest of the Municipality of Alcoy, Cebu. A list of indicators was used to identify the conservation status of the Native trees at the local level. A total of 135 native trees from 48 families and 105 genera were recorded. Most species belong to the families of Euphorbiaceae, Lauraceae, Moraceae, Clusiaceae, Myrtaceae, Meliaceae, Fabaceae, and Rutaceae. In this study, 62 species were categorized as threatened, and 72 species as Least Concern, while in IUCN classification 19 threatened species were recorded, and 111 taxa considered as Least Concern respectively. Using the DENR method of classification 15 threatened species were recorded, and 115 taxa considered as Not Evaluated. The Nug-as forest was degraded by illegal cutting, kaingin, hunting and charcoal making. Based from Beynen and Townsend analysis, Nug-as forest was categorized as moderately disturbed. While DENR and IUCN declaration on the status of the Philippine native trees take a very long time, threatened plant species would be gone before we know it, considering the destruction rate in the Philippines.

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.

Threatened Fauna

The aims of this study were to identify common ecological patterns among threatened fauna in New South Wales, and to identify priority areas for research and management by determining which regions and habitats contain high numbers of threatened fauna. Threatened and non-threatened fauna were taken from the listings of Lunney et al. (1996, 1997). Species were categorized into weight classes, diet groups, habitats and regions and by level of knowledge available about them. All regions and habitats of the State contain threatened species. The northeastern region of New South Wales contains the greatest number of threatened species but the western region has suffered the most extinctions, especially of mammals. Species that historically inhabited a greater number of regions are less likely to be currently threatened or to be extinct than those with restricted distributions, and large species are more likely to be threatened than smaller species. The best predictors of a threatened mammals species were seeds and vegetation in the diet, heavier body weight, and ground-dwelling, burrowing, and rock pile/cave-dwelling habits. The Critical Weight Range (35?5 500g), although strongly associated with extinction of non-volant mammals, was not the most important predictor. Lord Howe Island held the highest proportion of threatened and extinct birds. Factors showing the strongest associations for threatened birds were carnivory, large size, and distribution in the southeastern region. The most poorly-known region for birds was the north-east, and the least known habitat was shrubland (including mallee, heath and chenopod shrubland). The status of reptiles was poorly known in all regions, especially the western region. Frogs were also poorly known in all regions. Frogs were most at risk if they were large, inhabited closed forest or occurred in the central or northeastern region. The study further revealed little association between particular ecological attributes and conservation status. This indicates that there are complex and pervasive threats affecting the status of New South Wales fauna. Research and management priority status could be argued for all regions and most habitats in the State, but the western or northeastern regions may face the most problems depending on the criteria used (e.g., past extinctions, number vs proportion of threatened species). Further, the conservation status of birds, reptiles and frogs is in particular need of attention from researchers.

The Freie Wähler (free voters, FW) offer the rare chance to analyze parties in the making. Their long-time anchoring in local elections, centrist, middle-class political orientation, and bifurcated organizational structure distinguish them from other new political parties that aspire to participate in Land (state), national and European elections. Against the backdrop of FW success in Bavaria, where they received 10.2 percent of the vote in 2008, this article explores the FW expansion to the state level but not their national aspirations. In contrast to most studies that emphasize opportunity structures that work in favor of new political actors, this article highlights their dialectical nature. For example, the FW self-image is based on their difference from political parties, but the rules of the game push them to the status of "almost-party" at the local level and parties at the Land level. Their local roots are a source of legitimacy, but when they reach beyond, divisions among members and voters hold back their electoral fortunes. Independence and issue orientation are appealing to some voters but hamper the establishment of a clear identity and effective campaigning in state elections. Success for FW candidates is linked to the weakness of the dominant parties in the conservative camp. Spatial-temporal conditions are significant in considering the future of the FW at the Land level.

Threatened Plant Species

In order to achieve certain targets of the Global Strategy for Plant Conservation (GSPC), countries should aim to have at least 75% of their threatened species preserved in ex situ genetically representative collections, preferably in the country of origin, and at least 20% of the threatened species must be available for recovery plans and restoration programs (Target 8). Assessing the conservation value of ex situ collections is needed in order to identify the gaps in gene banks and to determine the baseline situation. Selection of the target species for conservation followed the Regional Responsibility criterion, as the first-order of priority at the local level with highest ranking given to species whose distribution is endemic to the study area. Data analysis was performed on 85 species listed in the Valencian Catalog of Threatened Plant Species (VCTPS) stored in the Germplasm Bank Collections of Valencian Flora, Spain. Our results show that conservation value of an ex situ collection will depend on whether the analysis is based on the representation of species (i.e. the presence or absence of species in an ex situ collection) or based on their representativeness (i.e. how well the collected and stored natural populations represent the “theoretical” species genetic diversity and what is the potential to produce plants for recovery actions, summarized in the proposed index R4). For 85 species listed in VCTPS the existing ex situ seed bank collections keep samples of 91.8% (78 species), indicating good representation. However, the criteria accounting for number of populations collected and quality of the stored germplasm revealed that less than 50% of the listed species are properly preserved in the ex situ collections.

SummaryLaos is an important country for bird conservation. Bird surveys between 1992 and 1996, the first since 1949, covered 20 main areas, with incidental records from many others.This paper reviews the status of all Lao species reported to be of elevated conservation concern (key species) in any of the following categories: Globally Threatened or Globally Near-Threatened (sensu Collar and Andrew 1988 and Collar et al. 1994), and At Risk or Rare in Thailand (sensu Round 1988 and Treesucon and Round 1990). Several additional species are covered which have clearly undergone a National Historical Decline in Laos. A comprehensive review of other Lao species was not possible, and some species which are in truth of conservation concern have doubtless been overlooked. Historical and modern records were reviewed and population trends identified where possible.Current global status listings (Collar et al. 1994) were supported, except that consideration should be given to changing Red-collared Woodpecker Picus rabieri and Sooty Babbler Stachyris herberti from Threatened to Near-Threatened. If the Lao situation is representative of the species throughout their range, then consideration should also be given to placing Ratchet-tailed Treepie Temnurus temnurus and River Lapwing Vanellus duvaucelii as Near-Threatened.Twenty-seven Globally Threatened species are known from Laos, of which there are recent records of 22. There are recent unconfirmed records of two more. Forty-seven Globally Near-Threatened species are known from Laos, of which there are recent records of 39; there are unconfirmed records of one further species. Five Globally Threatened and five Near-Threatened species were recorded for the first time in Laos in recent years, suggesting that further species of elevated conservation concern remain to be found.

Taking Action

The Aichi Biodiversity targets are a set of twenty targets for the Convention of Biological Diversity (CBD) that were developed with the intention to help each participating country to measure the progress made in preventing the loss of biological diversity. These targets provide a 10-year period for taking action by the countries. These targets setup in 2010 are expected to be achieved within 2020 by all the 193 countries signatory to CBD. Aichi Biodiversity Target 12 is considered to be one of the most important targets, which is directly or indirectly linked to all of the other 19 CBD Targets. Aichi-12 sets up the goal for each country to prevent the extinction of known threatened species and improve the conservation status of those species that are on decline. This target calls for establishment of conservation plans for species that face a high risk to extinction. Hence, it is of urgent need to understand the extinction risk posed to each of the threatened species in the country and the factors that are responsible for the population decline in species. Therefore, it is important for taking initiatives to remove/reduce those factors posing risk to the survival of species. This study presents a brief overview of the status and progress made by India towards achievement of Aichi-12.

The Status

The 1972 World Heritage Convention (WHC), along with the 1994 Global Strategy, aim to preserve the outstanding universal value of internationally important cultural and natural sites within a "representative, balanced and credible" network of highly-protected areas. Increasing human pressures and shortfalls in representation have been documented across the World Heritage network, particularly in terrestrial and cultural sites, threatening the integrity and primary goals of the WHC. However, the conservation status of current and tentative (i.e., proposed) marine natural World Heritage areas remains relatively unknown. We assessed the extent of recent (2013) and historical (2008-2013) cumulative human impacts and several metrics of representation (country, continent, ecoregion, wilderness, and threatened species) within existing and tentative marine natural World Heritage areas. We found moderate yet increasing cumulative human impacts across most existing sites, and high or very high impacts across the majority of tentative sites. Climate change impacts comprised nearly 75% of impact scores, on average, and differences in land and marine impacts across sites could help prioritise management decisions. Over 75% of marine ecoregions and 85% of threatened species considered in this study have no representation within the existing marine natural World Heritage network. We outline examples of how prioritizing representation across tentative sites for future World Heritage listing could greatly increase these measures. We urge the WHC to adopt quantitative, systematic and transparent evaluations of how current and tentative sites contribute to the overarching goals of maintaining a representative World Heritage network and preserving their outstanding universal values for future generations.

Glacial Relict

The first reliable information on the occurrence of <em>Rhododendron ferrugineum</em> in the Karkonosze Mts (excluding spots of directly acknowledged anthropogenic origin) was provided by A. Boratyński in 1983, but the status and origin of the plants were unknown. A recent phylogeographical study proved the natural character and relict status of the aforementioned population, which makes it the northernmost and most isolated site within the whole distribution of the species. In this study, we characterized the basic aspects of the ecology and conservation status of the population and, more specifically, focused on assessing the size of the population, general health of individuals, generative propagation ability, habitat conditions, and potential threats for the species. The population persists in the Sowia Dolina (east part of the Karkonosze Mts), in a microtopographically controlled, treeless microrefugium. Shrubs of <em>R. ferrugineum</em> are part of an acidophilous dwarf-heath plant community, similar to those occurring in the Alps and the Pyrenees, although less species-diverse. The plant community in the Karkonosze Mts has been preliminarily classified into the <em>Genisto pilosae-Vaccinion</em> alliance. The <em>R. ferrugineum</em> population consists of 68 individuals: 57 fully grown and juvenile and 11 seedlings. In 2017, 10 individuals flowered, seven of which developed fruits, while in 2018, 15 individuals produced flowers and eight developed mature fruits. Seeds collected in 2017 germinated in high numbers. Plants in the Karkonosze population hosted some fungal parasites typically found in <em>Rhododendron</em> species, but no intense disease symptoms strongly influencing plant fitness were observed. A combination of significant isolation, genetic distinctness, and high genetic diversity implies a high conservation priority for the <em>R. ferrugineum</em> population in Karkonosze. Despite the theoretical threats, including stochastic risks, the <em>R. ferrugineum</em> population seems to have been stable for a long time and, importantly, it is composed of individuals of different ages, from large flowering plants to seedlings.

Bat Conservation

Effective science-based conservation priorities and policies are crucially important to effectively maintain biodiversity into the future. For many threatened species and systems insufficient information exists to generate priorities, or the mechanisms needed to effectively conserve species into the future, and this is especially important in megadiversity countries like the Philippines, threatened by rapid rates of development and with few overarching strategies to maintain their biodiversity. Here, using a bibliographic approach to indicate research strengths and priorities, we summarised scientific information on Philippine bats from 2000-2017. We examine relationships between thematic areas and effort allocated for each species bat guild, and conservation status. We found that an average of 7.9 studies was published annually with the majority focused on diversity and community surveys. However, research effort is not even between taxonomic groups, thematic areas or species, with disproportionate effort focusing on ‘taxonomy and systematics’ and ‘ecology’. Species effort allocation between threatened and less threatened species does not show a significant difference, though this may be because generalist species are found in many studies, whereas rarer species have single species studies devoted to them. A growing collaborative effort in bat conservation initiatives in the Philippines has focused on the protection of many endemic and threatened species (e.g., flying foxes) and their habitats. The implementation of conservation relevant policies, outreach programs, capacity building, and mainstreaming of evidence-based conservation are encouraged to strengthen bat conservation in the Philippines.
