Seagrass species distribution and cover (as percentage cover in categories: 0, 0-10%, 10-25%, 25-50%, 50-75%, 75-90%, 90-100%), epiphytic cover (as none, low, medium or high) and macroalgae cover (as percentage cover in categories: 0, 0-10%, 10-25%, 25-50%, 50-75%, 75-90%, 90-100%) were recorded at each site. At approximately a third of the sites, physical water profiles, secchi depth and photosynthetically active radiation (euphotic depth) were conducted from 2018 onwards. When observation locations were inaccessible by boat, sites were accessed from kayaks paired with drone imagery which was used to make observations. The datasets making up the Leschenault seagrass survey data are: Leschenault_Seagrass - point dataset Leschenault_Seagass_Extent - polygon showing presence/absence derived from points Leschenault_Seagrass_Cover -polygon showing percentage cover derived from points Layers: <code> Leschenault_Seagrass_Apr_2009 - Leschenault_Seagrass points where Year = '2009' Leschenault_Seagrass_Feb_2015 - Leschenault_Seagrass points where Year = '2015' Leschenault_Seagrass_Feb_2016 - Leschenault_Seagrass points where Year = '2016' Leschenault_Seagrass_Feb_2017 - Leschenault_Seagrass points where Year = '2017' Leschenault_Seagrass_Feb_2018 - Leschenault_Seagrass points where Year = '2018' Leschenault_Seagrass_Feb_2019 - Leschenault_Seagrass points where Year = '2019' Leschenault_Seagrass_Feb_2020 - Leschenault_Seagrass points where Year = '2020' Leschenault_Seagrass_Feb_2021 - Leschenault_Seagrass points where Year = '2021' Leschenault_Seagrass_Feb_2022 - Leschenault_Seagrass points where Year = '2022' Leschenault_Seagrass_Feb_2023 - Leschenault_Seagrass points where Year = '2023' Leschenault_Seagrass_Extent_Apr_2009 - Leschenault_Seagrass_Extent where Year = '2009' Leschenault_Seagrass_Extent_Feb_2015 - Leschenault_Seagrass_Extent where Year = '2015' Leschenault_Seagrass_Extent_Feb_2016 - Leschenault_Seagrass_Extent where Year = '2016' Leschenault_Seagrass_Extent_Feb_2017 - Leschenault_Seagrass_Extent where Year = '2017' Leschenault_Seagrass_Extent_Feb_2018 - Leschenault_Seagrass_Extent where Year = '2018' Leschenault_Seagrass_Extent_Feb_2019 - Leschenault_Seagrass_Extent where Year = '2019' Leschenault_Seagrass_Extent_Feb_2020 - Leschenault_Seagrass_Extent where Year = '2020' Leschenault_Seagrass_Extent_Feb_2021 - Leschenault_Seagrass_Extent where Year = '2021' Leschenault_Seagrass_Extent_Feb_2022 - Leschenault_Seagrass_Extent where Year = '2022' Leschenault_Seagrass_Extent_Feb_2023 - Leschenault_Seagrass_Extent where Year = '2023' Leschenault_Seagrass_Cover_Apr_2009 - Leschenault_Seagrass_Cover where Year = '2009' Leschenault_Seagrass_Cover_Feb_2015 - Leschenault_Seagrass_Cover where Year = '2015' Leschenault_Seagrass_Cover_Feb_2016 - Leschenault_Seagrass_Cover where Year = '2016' Leschenault_Seagrass_Cover_Feb_2017 - Leschenault_Seagrass_Cover where Year = '2017' Leschenault_Seagrass_Cover_Feb_2018 - Leschenault_Seagrass_Cover where Year = '2018' Leschenault_Seagrass_Cover_Feb_2019 - Leschenault_Seagrass_Cover where Year = '2019' Leschenault_Seagrass_Cover_Feb_2020 - Leschenault_Seagrass_Cover where Year = '2020' Leschenault_Seagrass_Cover_Feb_2020 - Leschenault_Seagrass_Cover where Year = '2021' Leschenault_Seagrass_Cover_Feb_2020 - Leschenault_Seagrass_Cover where Year = '2022' Leschenault_Seagrass_Cover_Feb_2020 - Leschenault_Seagrass_Cover where Year = '2023' </code> {"type": "Polygon", "coordinates": [[[115.67239330900009, -33.320280975999935], [115.71527693700011, -33.320280975999935], [115.71527693700011, -33.198694899999964], [115.67239330900009, -33.198694899999964], [115.67239330900009, -33.320280975999935]]]} 115.67239330900009 115.71527693700011 -33.320280975999935 -33.198694899999964 Biota Estuary Flora Seagrass Leschenault Estuary Seagrass Survey documentDigital Department of Water and Environmental Regulation (DWER) metadata statement.

SHP Licence Agreement documentDigital DWER Active Acceptance Licence Agreement PDF Web Feature Service documentDigital Web Feature Service (WFS) provides an interface that allows requests for geographical features across the web using platform independent calls. WFS allows a user to download and spatially analyse the features within a datset. This service is aimed at advanced geographical information users, and will require access to geographical information system (GIS) software such as QGIS and ArcGIS. WFS ArcGIS Server Map Service documentDigital An ArcGIS Server Map Service offers access to a geographic dataset - such as a map or imagery - by providing a set of tiled images for use in web-based maps. Depending on the capabilities enabled, this web service may also allow a client to dynamically draw, search, and query its features. This service is aimed at advanced geographical information users, and will require access to geographical information system (GIS) software such as ArcGIS and QGIS. API ArcGIS Server Map Service Web Mapping Service documentDigital Web Map Service (WMS) is a standard protocol for serving georeferenced map images over the internet that are generated by a map server using data from a GIS database. WMS allows a user to spatially visualise the dataset, and query individual features, but does not allow downloading the raw data.
