a b s t r a c t Freshwater ecosystems represent one of the most threatened broad habitat types globally. Despite containing around a third of all vertebrates, area-based approaches to conservation planning rarely include freshwater species as an explicit target for conservation. Here we describe and apply a globally applicable methodology comparable to those for other groups (i.e. Important Bird Areas) to identify river and lake catchments that represent, or contain, freshwater Key Biodiversity Areas. We discuss the rationale behind the methodology and propose appropriate definitions and quantitative threshold values for the selection criteria. Thresholds are developed through spatial analysis of species information for four comprehensively assessed freshwater taxonomic groups in continental Africa, comprising 4203 species, as recently assessed for the IUCN Red List of Threatened Species™. To illustrate application of the methodology freshwater Key Biodiversity Areas are identified across continental Africa, and conservation planning software used to prioritise a network of catchments that captures 99% of the total species complement within catchments covering ca. 20% of the total land area. Within these prioritised catchments only 19% of river length falls within existing Protected Areas suggesting that, given the high connectivity within freshwater ecosystems and their dependence upon catchment management for effective conservation, modification or expansion of the protected area network is required to increase effective conservation of freshwater species. By applying this methodology, gaps in the coverage of freshwater species by existing Protected Areas can be identified and used to inform conservation policy and investment to ensure it is inclusive of, and effective for, freshwater biodiversity.

...are acknowledged as being amongst the principle threats to biodiversity globally (Vié et al., 2009). With a new global target for coverage by PAs set at 17% for terrestrial habitats and inland water following the 10th meeting of the Conference of the Parties to the Convention on Biological Diversity there is a need to expand the network in a strategic way (Margules and Pressey, 2000; Eken et al., 2004; Rodrigues et al., 2004a). Locations of new PAs have been identified either for pragmatic reasons (Margules 168 R.A. Holland et al. / Biological Conservation 148 (2012) 167–179and Pressey, 2000; Joppa and Pfaff, 2009) or on the basis of our understanding of better known groups, predominantly mammals, birds and amphibians (Brooks et al., 2004; Rodrigues et al., 2004b; Ricketts et al., 2005; Rondinini et al., 2005) in the belief that these will act as surrogates for lesser known groups. However, surrogacy between taxonomic groups from differing realms (i.e. freshwater vs. terrestrial) is low (Rodrigues and Brooks, 2007; Darwall et al., 2011) with studies in the United States (Herbert et al., 2010; Lawrence et al., 2011) and Brazil (Nogueira et al., 2010) demonstrating that existing PAs provide significantly ...

Protected areas are effective at stopping biodiversity loss, but their placement is constrained by the needs of people. Consequently protected areas are often biased toward areas that are unattractive for other human uses. Current reporting metrics that emphasise the total area protected do not account for this bias. To address this problem we propose that the distribution of protected areas be evaluated with an economic metric used to quantify inequality in income — the Gini coefficient. Using a modified version of this measure we discover that 73 % of countries have inequitably protected their biodiversity and that common measures of protected area coverage do not adequately reveal this bias. Used in combination with total percentage protection, the Gini coefficient will improve the effectiveness of reporting on the growth of protected area coverage, paving the way for better representation of the world’s biodiversity.

Madagascar is known for having one of the most diverse ecosystems in the world. Unfortunately, the country’s natural habitat has been declining for decades. One study estimated that only 7 % of Madagascar’s original vegetation is intact. In 1927, Madagascar implemented its first Protected Areas (PAs). Prior to 2003, approximately 3 % of the country’s land was protected. By 2008, this number more than tripled reaching 9.4 % or just over 5.5 million hectares. Protected Areas have been used throughout the world to manage, conserve, and protect, geographic areas that would otherwise be subject to activities that could threaten their environmental and economic value. Nevertheless, few studies evaluate the effectiveness of PA networks with controls. The purpose of this study was to determine the impact Madagascar’s PAs have had on deforestation from 1990 to 2005. I use matching to make ‘apples to apples ’ comparisons with respect to geographic land characteristics. A control method such as matching is essential since PAs are often non-randomly distributed.

Protected area coverage has reached over 15% of the global land area. However, the quality of management of the vast majority of reserves remains unknown, and many are suspected to be "paper parks". Moreover, the degree to which management can be enhanced through targeted conservation projects remains broadly speculative. Proven links between improved reserve management and the delivery of conservation outcomes are even more elusive. In this paper we present results on how management effectiveness scores change in protected areas receiving conservation investment, using a globally expanded database of protected area management effectiveness, focusing on the "management effectiveness tracking tool" (METT). Of 1934 protected areas with METT data, 722 sites have at least two assessments. Mean METT scores increased in 69.5% of sites while 25.1% experienced decreases and 5.4% experienced no change over project periods (median 4 years). Low initial METT scores and longer implementation time were both found to positively correlate with larger increases in management effectiveness. Performance metrics related to planning and context as well as monitoring and enforcement systems increased the most while protected area outcomes showed least improvement. Using a general linear mixed model we tested the correlation between change in METT scores and matrices of 1) landscape and protected area properties (i.e. topography and size), 2) human threats (i.e. road and human population density), and 3) socio-economics (i.e. infant mortality rate). Protected areas under greater threat and larger protected areas showed greatest improvements in METT. Our results suggest that when funding and resources are targeted at protected areas under greater threat they have a greater impact, potentially including slowing the loss of biodiversity.

Geldmann et al. / Biological Conservation 191 (2015) 692–6994.2. What determines change? Protected area size had a significant correlation with increases in management effectiveness scores. Similar patterns have been found both for terrestrial (Struhsaker et al., 2005; Joppa and Pfaff, 2011) and marine protected areas (Edgar et al., 2014). However whether available resources are better invested in larger protected areas, often located in remote areas (Joppa and Pfaff, 2009) is a heated discussion. Larger protected areas have a proportionately smaller edge to pressures and through their remote location often result in relatively intact biodiversity values (Mittermeier et al., 2003) making them attractive for furtherconservation investment. However, large and remote protected areas often experience little pressure, protected or not (Joppa and Pfaff, 2011) suggesting resources may be better invested in smaller protected areas which would otherwise experience greater biodiversity loss (Craigie et al., 2014). We found a significant positive correlation between local ...

Resumen: Las aves marinas son el grupo más amenazado de animales marinos ya que el 29% de las especies tienen algún riesgo de extinción. Amenazas significativas para las aves marinas suceden en las islas donde se reproducen, pero en muchos casos la conservación efectiva de islas puede mitigar estas amenazas. Para orientar las acciones de conservación de aves marinas en islas, identificamos todas las islas con poblaciones existentes o extirpadas de 98 especies de aves marinas amenazadas, identificadas en la Lista Roja de la UICN, y cuantificamos la presencia de especies invasoras amenazantes,áreas protegidas y poblaciones humanas. Igualamos estos resultados con los atributos de la isla para resaltar las oportunidades de conservación factibles en la isla. Identificamos 1, 362 poblaciones reproductivas de aves marinas en 968 islas. En 803 (83%) de estas islas identificamos especies invasoras amenazantes (205), cobertura incompleta delárea protegida (23%) o ambas (40%). La mayoría de las islas con aves marinas amenazadas son receptivas a una acción de conservación de toda la isla ya que son pequeñas (el 57% fue < 1km 2 ), deshabitadas (74%) y se encuentran en países de ingresos altos o de nivel medio (96%). Estos atributos colectivamente hacen que las islas con aves marinas amenazadas sean una oportunidad rara para la conservación efectivo a escala.

Protected areas are widely considered essential for biodiversity conservation. However, few global studies have demonstrated that protection benefits a broad range of species. Here, using a new global biodiversity database with unprecedented geographic and taxonomic coverage, we compare four biodiversity measures at sites sampled in multiple land uses inside and outside protected areas. Globally, species richness is 10.6% higher and abundance 14.5% higher in samples taken inside protected areas compared with samples taken outside, but neither rarefaction-based richness nor endemicity differ significantly. Importantly, we show that the positive effects of protection are mostly attributable to differences in land use between protected and unprotected sites. Nonetheless, even within some human-dominated land uses, species richness and abundance are higher in protected sites. Our results reinforce the global importance of protected areas but suggest that protection does not consistently benefit species with small ranges or increase the variety of ecological niches.
