取樣方法

In Field data Capture Steps a) Draw polygon - Observe area and determine a polygon outline based on vegetation type boundaries (composition and structure) – outline polygon on map. If aerial imagery doesn’t represent what’s on the ground, use GPS to record boundaries/indicative waypoints. b) Capture field data – For each delineated mapping unit first record hydrosystem, wetland type and vegetation structure. Then record vegetation composition. Follow Atkinson (1985) procedures to determine vegetation structure and then record composition. Following Johnson & Gerbeux (2004) annotate directly on field map or use additional field sheet(s) with reference number marked on map. Record different canopy or height tiers (max 3) with dominant species (shouldn’t need more than 3-4). c) Record information for other fields and any general notes on the map and for data recorded in additional field sheets. Need to identify to species level, i.e. not “introduced grasses”. Take RTU samples to ID later.

方法步驟描述:

1. GIS Mapping Instructions • In your ArcGIS Pro project edit the layer “Wetland Vegetation Habitats - Staging” • Edit using the Latest Imagery for the area • Map at 1:500 or higher. • There are 15 fields for each record (row). These are described in Table 1 below with associated reference/links. • Calculate geometry for non-auto fields (ha & m2) (right click on the field header) • Once completed all the fields export or ‘copy’ and ‘paste’ into an excel sheet and create pivot table to determine types and extents for completion of the access database assessments (calculate the areas of hydrosystems, wetland classes, vegetation types etc). • Add wetland polygons to Canterbury Wetlands – Staging layer – Table 2. Important, only “wetland” polygons should be copied into the Canterbury Wetlands Staging layer • Once the surveyor has completed “Wetland vegetation habitats – staging” and Canterbury Wetlands – Staging data entry, surveyor to forward survey site name to review team. • Reviewer will put finalised mapped habitats (both wetland and terrestrial) into the Wetland Vegetation Habitats layer. • Surveyor to fill out attributes of Canterbury Wetlands – Staging layer. These attributes will require analysis (pivot) of the Wetland Vegetation Habitats that the surveyor will have created for wetland condition assessment. • Reviewer to ensure attribute and polygon naming and for a final version in Canterbury Wetlands – Editable. • Reviewer to ensure that the polygons have a unique Wetland ID for each separate polygon area (use CW Layer - Wetland ID tracking tool.xlsm to identify unique wetland ID’s). For remeasured areas a letter suffix can be added to keep track of the wetlands as extent changes through time. For example, an aerial polygon identified in 2015 with wetland ID 1516. A new ground survey completed in 2024 split the aerial polygon into 2 areas that overlap the original extent these 2 areas should keep the original ID and have a suffix added 1516A and 1516B. • Reviewer will undertake archiving of old/edited layers. • Review team to determines whether permanent monitoring plots will be established at the site. GBIF Data conversion • GBIF data conversion can be completed in Arc Gis Pro using and Arc Gis Tool box that was created that follows a 20 process step to generate this dataset.
