    Falkland Islands KBA Analysis for Coastal Marine Birds

    Falkland Islands KBA analysis for coastal marine birds Summary for Stakeholders July 2021 (For detailed of overview of data and analyses presented in this document, please see the associated Technical Report) Darwin Plus Project Reference No: DPLUS115: Unlocking Falkland Islands Marine Management: Key Biodiversity Areas for seabirds. Principle Project Team: Emma Harte (FC), Andrew Stanworth (FC), Jonathan Handley (BLI) and Maria Dias (BLI). Point of Contact: Emma Harte: [email protected] Introduction Context The Falkland Islands support internationally important seabird populations. Spatial use of the Falklands marine environment by seabirds has been repeatedly assessed; however, outputs from these studies have been specific to the respective projects and have not directly aligned to specific global frameworks. One global framework is Key Biodiversity Areas (KBAs). These are internationally recognised sites that are assessed against a global standard and that contribute significantly to the global persistence of biodiversity. KBAs are manageable units with delineated boundaries. KBAs come with no legal standing unless implemented by the governing body with jurisdiction for the site. They are fundamentally an information tool which should inform data-led terrestrial or marine management. KBAs have already been identified in the Falklands for terrestrial locations (based predominantly on bird and plant data) and in the nearshore/inshore environment for sei whales; however this is the first project to specifically assess a number of seabird species within the nearshore marine environment. All the species assessed are breeding coastally in the Islands and are central placed foragers during that time i.e. they repeatedly return to the colony in order to breed and rear young.

JOHNSGARD Received on 14 May 1960 Delacour & Mayr's (1945) classic revision of the Anatidae took waterfowl behaviour into account to a much larger degree than had any previous classifications of the group. However, their utilization of behavi~>ur was primarily at the tribal and generic levels, and no real attempt was made to :use behaviour for det!!rmining intrageneric relationships. Thus far only Lorenz (1941, 1951-1953) has seriously attempteq this with waterfowl, and his analysis of the relatiOnShips within the genus Anas (sensu De1acour & Mayr) has provided a remarkable insight into the evolution of this group.

University Ave., Laramie, WY 82071 USA. Abstract The Falkland Islands have been aff ected by anthropogenic-induced habitat modifi cation including introduction of invasive species and grazing by livestock. Introduced Norway rats are known to have a large eff ect on native Falklands passerines but their eff ect on other native birds has not been explored. We investigated the eff ects of several environmental variables, including the presence of Norway rats and chronic grazing by livestock, on an assemblage of 22 species of coastal waterbirds by comparing species richness and relative abundance of birds among 65 rat-infested islands, 29 rat- eradicated islands and 76 historically rat-free islands. Bird count data from 299 km of coastline were used to estimate relative bird abundance, expressed as the number of individuals per kilometre of coastline for each species. Our study provided three key results.
