Windmill Islands vegetation monitoring quadrat photographs (2022-2023)

Full description

This record contains digital photographs collected between 2022 and 2023 for the Windmill Islands long term vegetation monitoring program under the projects AAS_4516 and AAS_4613. This record was prepared by Elka Blackman in December 2024.
The Windmill Islands long term vegetation monitoring program has been conducted between 2003-2023 under projects ASAC_1313, AAS_3042, AAS_4046, AAS_4516 and AAS_4613.
Quadrat photographs from previous years are presented in separate metadata records:
https://data.aad.gov.au/metadata/AAS_4046_QuadratPhotographs
https://data.aad.gov.au/metadata/AAS_4046_2014QuadratPhotographs

These photographs have been used to assess bryophyte and transitional community vegetation cover/health for the years 2003, 2008, 2012, 2013, 2014, 2022 and 2023.

Vegetation cover/health data is presented in separate metadata records:
https://data.aad.gov.au/metadata/AAS_4046_VegetationCoverData
ID: AAS_4516_VegetationCover (metadata ID to be provided here when this is available)

Quadrat location data at two sites in the Windmill Islands (ASPA 135 and Robinson Ridge) are provided in metadata ID: AAS_4046_quadrat_locations (doi:10.26179/5eaf9c864c3c7).
And shown in two maps which are available via the AADC map catalogue: http://data.aad.gov.au/aadc/mapcat/display_map.cfm?map_id=14450 http://data.aad.gov.au/aadc/mapcat/display_map.cfm?map_id=14451
Baseline survey was described in Metadata:
ID: ASAC_1313_Transects_2002-03 (doi:10.4225/15/55B197219CF2D)

Five and 10 year surveys described in ASAC_1313_Transects_2007-08 (doi:10.4225/15/55B1D23B3ED0E) and AAS_4046_Transects_2012-13 (doi:10.4225/15/59fbbb909cf71), respectively.

FILE: AAS_4516_QuadratPhotographs 2022-2023.zip

This zip file contains a number of subfolders as follows:
YEARS 2022 and 2023
SITES ASPA135 and ROB

These contain a subfolder for each quadrat:
Key to quadrat labels (all years from 2003 onwards): (e.g. AB1)
First character denotes site: A (ASPA 135) and R (Robinson Ridge).
Second character denotes vegetation community type: B (Bryophyte), T (Transitional) and L (Lichen) (Where B = greater than 90% bryophyte cover, T = approx. 50% live bryophyte: 50% moribund bryophyte cover, L = greater than 90% lichen cover).
Third (and fourth) character/s denotes transect number: 10 transects per site (numbered 1-10).
Each quadrat subfolder contains several files:

File naming convention:
SITE_YEAR_X#Y.JPG
Where:
SITE = ASPA (ASPA 135) or ROB (Robinson Ridge)
YEAR = Year the quadrat photograph was taken (2022 or 2023)
X = Community identifier: B = Bryophyte community, T = Transitional community; L = Lichen community
# = Transect number (1-10)
Y = The photo identifier for that quadrat/year (a, b, c, d etc.)

Funding and logistics support to collect these data were provided by
Australian Antarctic Science projects AAS_4516 (Waterman), and AAS_4613 (SAEF)
Australian Research Council grants (DP200100223)
