Falling through the cracks: are European directives and international conventions the panacea for freshwater nature conservation?

There are many ways of practising freshwater nature conservation: from strict legislative protection of individual species considered rare or threatened to protecting whole lakes or long stretches of rivers; from practical conservation management at a local scale to integrated catchment management at the river basin scale; and from the encouragement of better habitat management through codes of good practice to statutory control of pollution or abstraction. Whatever the mechanism, an essential pre-requisite is a way of choosing where to put the effort, especially when resources for nature conservation are severely limited. The aim of this article is to review the contribution from four specific international measures to the task of assigning priorities for conservation. The 1990s saw the introduction of two European directives (the Habitats Directive (HD) and the Water Framework Directive (WFD)) and one international convention (the Biodiversity Convention (CBD)) each with the potential for influencing, to a greater or lesser extent, the conservation of freshwater habitats and species. This article also discusses a much older convention – the Ramsar Convention – adopted in 1971 specifically to help tackle the conservation and management of wetlands and aquatic ecosystems. Although the authors have focused mainly on the UK, the subject is relevant to other parts of Europe and beyond. The article explores the degree to which these measures help in identifying the most important fresh waters for conservation, and asks whether or not they present the right conservation message to a wide audience.

Water conservation in the city of Pasadena

The object of this report will be to make a complete study of the water that is wasted in the storm drains of Pasadena and determine if there is any practical way of conserving this water.

Que paraíso é esse?: a turismização da Ilha Grande

A Ilha Grande (Angra dos Reis, RJ) apresenta dois acontecimentos que marcam a história recente do lugar: a instituição de leis ambientais com a criação de quatro unidades de conservação da natureza (entre 1971 e 1990); e a intensificação do fluxo turístico após a implosão do Instituto Penal Cândido Mendes - IPCM (1994), que marcou o fim de cerca de 100 anos de um sistema penitenciário. A Ilha, sempre associada às belezas naturais e à ideia de paraíso, a partir desse momento, deixa de ser referida como o paraíso-inferno e passa a ser reconhecida predominantemente pelas potencialidades paisagísticas, voltando-se para o turismo, que se torna um componente central da vida no lugar. Reconstituindo a trajetória do turismo na Ilha, e considerando o quadro atual das atividades turísticas (a partir da minha participação em fóruns para discussão e resolução dos problemas da Ilha, de pesquisa em jornais, e de entrevistas com moradores e participantes desses fóruns), mostro os significados e visões sobre o paraíso Ilha Grande e o turismo o que se tem e o se quer , tanto no nível dos discursos e das representações, quanto no nível das práticas e das relações sociais instituídas. Revela-se aí um campo de disputa entre diferentes atores sociais com interesses diversos para salvar e explorar a Ilha Grande; onde a natureza e o turismo se apresentam como dois elementos utilizados como estratégias para sobrevivência de grande parte da população e como estratégia política do poder público; um paraíso marcado pelo turismo e um paraíso para o turismo. Faço uma leitura da ocorrência e das implicações do turismo na Ilha Grande através da ideia de turismização, em analogia com o pensamento de Norbert Elias sobre processo civilizador e de J. S. Leite Lopes sobre ambientalização, e reconhecendo o diálogo e os embates entre o processo turismizador e o processo ambientalizador na Ilha Grande.

Not just another pretty reef: the Gainesville Florida Reef, a satellite of the worldwide Hyperbolic Crochet Coral Reef project: poster presentation

The Gainesville Florida Reef, a satellite of the Worldwide Hyperbolic Crochet Coral Reef, project not only shows the beauty of reefs but serves to: • Foster scientific communication through the visual arts • Raise awareness of the fragility of our coral reefs and the entire ecosystem • Support learning by creating physical models of geometric principles • Connect several areas on campus, including fine arts, mathematics and ecology and environmental sciences through collaboration and mutual interest • Encourage local community and alumni involvement through creating, observing and learning

The role of specially designated wildlife sites in freshwater conservation - an English perspective

The value of specially designated sites in conserving biodiversity has been a hotly debated issue for many years. The debate has recently been given fresh impetus by the creation of Natural England, the new Government Agency responsible for the protection and enhancement of the natural environment in England, and the challenges facing the management of designated sites resulting from the increasingly tangible effects of climate change. In the freshwater environment, the role of designated sites is very much under the spotlight because of the implementation of the European 'Water Framework' Directive, which aspires to holistic, ecologically-based management of aquatic habitats.This paper explores the underlying premises of, and rationale for, special site designations for wildlife, and provides a frank account of the inevitable clash of management philosophies that designated sites create in the freshwater environment, drawing on experiences of managing designated freshwater sites in England over the past decade. A positive role is outlined for designated sites in freshwater conservation, which addresses these management conflicts in a way that not only meets Government obligations towards these sites but also paves the way for enlightened, progressive management of the wider freshwater resource. As part of this account, attempts are made to clarify the relationship between key biodiversity-related policy drivers in the freshwater environment, and to explain how the spectre of climate change can be addressed within designated site management. The importance of strategic freshwater science, collaboratively designed and funded, in maximising the value of the designated freshwater site network to the wider freshwater habitat resource, is stressed.

Using RIVPACS for studies on conservation and biodiversity

Invertebrate conservation relies not only on public support and political will, but also on possessing an adequate understanding of the distribution and ecology of invertebrate species and communities. In the UK, RIVPACS is making an important contribution to assessing the conservation importance of river invertebrate assemblages. So far, work has largely centred on using RIVPACS as an integral part of SERCON (System for Evaluating Rivers for Conservation), in which data collected using the standard RIVPACS method are interpreted with reference to conservation criteria such as species richness and representativeness. Applications of RIVPACS to other areas of conservation - whether providing information on the ecological requirements of rare species, monitoring the success of river restoration projects, or making broader assessments of sustainability - are probably more limited, but merit further examination. It is important to develop closer links between RIVPACS and techniques such as SERCON and RHS (River Habitat Survey) in order to maximise the benefit each can bring tostudies on conservation and biodiversity. It should also be recognised that there are limitations in transferring such systems to other countries where approaches to nature conservation may be very different.
