Abstract:
This dataset shows the main low-tide feeding areas of variable oystercatchers during period prior to 1992.It is part of a dataset on 16 different birds and their habitats for 1991 and for 2007. All bird maps for 1991 were digitised from the book: The Estuary Where Our Rivers Meet The Sea (1992), edited by S.J Owen. All birds information came from Andrew Crossland, Park Ranger, Christchurch City Council. While a single original map included different species with their spatial and temporal distributions, the digitised ones have been created on a per bird basis. Each layer is named after the bird suffixed by source year. Data generally covers species type, roosting and nesting sites, seasonal, tidal and maximum distributions, and main and secondary feeding areas. Data attributes are the same in all layers covering things on birds identification, time period of data observations, purpose of geographic area. These include common bird name, bird code, maori name, scientific name, area/habitat type, area type/habitat code, period of data, a sort year, source details, and publication time. Using the 1991 GIS maps as a base, Andrew Crossland manually updated the birds data for 2007, and these were then screen-digitised. Due to time constraints, only the following birds were selected by Andrew for processing from a wider variety of the estuary birds: White-faced Heron, NZ Shoveler, Black Swan, Canada Goose, South Island Pied Oystercatcher, Eastern Bar-tailed Godwit, Pied Stilt, Pukeko, Royal Spoonbill, Little Cormorant, Black Cormorant, Little Black Cormorant, Pied Cormorant, Spotted Shag, Variable Oystercatcher, Black-billed Gull and Southern Black-backed Gull. |

This dataset was created for the Avon-Heathcote Estuary Ihutai Trust for display on their website. One of the Trust's aim is to disseminate as much information on the estuary to the public and to the scientific research community.
