The critical difference between these exercises and a monitoring project is that a monitoring project will clearly identify when we need to make a management response. A Model for Conservation Management and Monitoring Monitoring (as defined by Hellawell) is essentially a tool of practical conservation management, and Fig. 1.1 shows a simple, but effective, model for nature conser- tion management and monitoring. The need for clear decision-making is implicit in this model. First we must decide what would represent a favourable state for the key habitat or species, and then we must decide when to intervene if the state is (or becomes) unfavourable. A third, often overlooked, but equally important, decision concerns when we would consider the habitat or species to have recovered; this is unlikely to be the same point that we became concerned about it. This decision not only has resource imp- cations, it can also have major implications for other habitats and species (prey species are an obvious example). All of these decisions are essen | | 出版日期 | Book 2010 | | 关键词 | Condition indicators; Conservation management; Monitoring; Naturalness; Surveillance; Vegetation; algae; bi | | 版次 | 1 | | doi | https://doi.org/10.1007/978-1-4020-9278-7 | | isbn_softcover | 978-94-017-7733-9 | | isbn_ebook | 978-1-4020-9278-7 | | copyright | Springer Science+Business Media B.V. 2010 |
