| Abstract: |
Frost flats are a naturally uncommon ecosystem which occur on the North Island volcanic plateau. This dataset identifies their location and includes GPS photos from the sites. |
|---|
| Statement: |
The frost flat ecosystems in this dataset are classified using Singers and Rogers 2014 Ecosystem classification and type.
Frost flat heathlands comprise short sclerophyllous shrublands dominated by the ericaceous
shrub monoao (Dracophyllum subulatum) on well-drained, infertile volcanic soils. They were
characteristic of shallow basins on the North Island Volcanic Plateau mantled by deep
deposits of infertile rhyolitic tephra. Despite their occurrence well below
regional treeline under climates that are generally amenable for plant growth, the most
ecologically stressed sites are subject to a year-round frost regime resulting from cold air
ponding; this maintains the treeless community. The potential additional role of soil infertility
in excluding native forest from frost flats remains unexplored.
This dataset also includes photo points for the sites. |

| Abstract: |
Frost flats are a naturally uncommon ecosystem which occur on the North Island volcanic plateau. This dataset identifies their location and includes GPS photos from the sites. |
|---|
| Statement: |
The frost flat ecosystems in this dataset are classified using Singers and Rogers 2014 Ecosystem classification and type. This dataset was mapped in July 2021 using the most recent available aerial imagery sourced from the LINZ Data Service.
Frost flat heathlands comprise short sclerophyllous shrublands dominated by the ericaceous
shrub monoao (Dracophyllum subulatum) on well-drained, infertile volcanic soils. They were
characteristic of shallow basins on the North Island Volcanic Plateau mantled by deep
deposits of infertile rhyolitic tephra. Despite their occurrence well below
regional treeline under climates that are generally amenable for plant growth, the most
ecologically stressed sites are subject to a year-round frost regime resulting from cold air
ponding; this maintains the treeless community. The potential additional role of soil infertility
in excluding native forest from frost flats remains unexplored.
This dataset also includes photo points for the sites, these have GPS locations and are available in the project folder. Refer to other dataset information for that link. |
