    Abstract

    1. Performance assessment, impact detection and the assessment of regulatory compliance are common scientific problems for the management of protected areas. Some habitats in protected areas, however, are rare and/or variable and are not often selected for study by ecologists because they preclude comparison with controls and high community variability makes meaningful change detection difficult.
    2. Low volume coastal saline lagoons are habitats that experience comparatively high levels of stress due to high physical variability. Lagoons are rare, declining habitats found in coastal regions throughout Europe where they are identified as one of the habitats most in need of protected area management.
    3. The macroscopic infauna in the sediments of 26 coastal saline lagoons were sampled, sieved and enumerated. Temporal and spatial variation in three of these [protected] lagoon communities was investigated further over five years.
    4. In a multivariate analysis of community structure similarities were found between some lagoons but in other cases communities were unique or specific to only two sites. The protected lagoons with these unique/specific communities showed significant temporal and spatial variation, yet none of the changes observed were attributed to anthropogenic impacts and were interpreted as inherent variability.
    5. The aim of control chart analysis is to characterise background variability in a parameter and identify when a new observation deviates more than expected. Multivariate control charts can operate without experimental controls and were used to assess community changes within the context of ‘normal’ variability. In only one year were changes genuinely ‘unusual’ and corresponded with the coldest December in over 100 years.
    6. Synthesis and applications: Multivariate control charts are likely to have wide application in the management of protected areas and other natural systems where variability and/or rarity preclude conventional analytical and experimental approaches but where assessments of condition, impact or regulatory compliance are nonetheless required.
