This dataset was first added to LRIS Portal on 01 May 2018.

This layer was derived from three existing data layers: the Land Cover Database 2 (LCDB2) (MfE 2002); the Land Use Map (LUM) from the Land Use Carbon Analysis System (MfE 2008; Dymond et al. 2012); and EcoSat Forests (Shepherd et al. 2002). Indigenous forest classes from EcoSat Forests were combined with classes from LCDB2 to form basic ecosystems classes. Where indigenous forest was mapped by LCDB2, the type of forest was determined from the EcoSat Forests layer. The eight forest types of EcoSat Forests were reduced to three basic types: beech forest; podocarp-broadleaved forest; and mixed beech and podocarp-broadleaved forest. To produce a recent 2008 layer the LUM was used to update indigenous and exotic forest changes since 2002. The mapping was performed using 15 m pixels, which is equivalent to a mapping scale of approximately 1:50 000.

Gorse Density 2013

Added
19 Jun 2018

This dataset was first added to LRIS Portal on 19 Jun 2018.

Gorse density has been classified within 4 ha (200 x 200 m) tiles as either absent (transparent), low density (< 1 plant/ha = yellow), moderate density (<10 plants/ha = orange) or high density (>10 plants/ha = red). Tiles overlap because classification was carried out on individual photos prior to mosaicking. The highest density takes precedence when tiles overlap.

Updated
30 Mar 2016

This dataset was last updated on LRIS Portal on 30 Mar 2016.

This raw aerial photography covers 23,000 ha of the Desert Road stretch of SH 1 running through the Central Plateau is provided to members of the Desert Rd Invasive Legume Control Group so that they can locate plants and prioritize areas where ground control is required. Gorse competes with native vegetation and can produce seed that remains viable in the soil for decades.

Estimated image resolution = 0.28 m

This raw aerial photography covers 23,000 ha of the Desert Road stretch of SH 1 running through the Central Plateau is provided to members of the Desert Rd Invasive Legume Control Group so that they can locate plants and prioritize areas where ground control is required. Lupin spreads rapidly and competes with native vegetation.

This dataset was first added to LRIS Portal on 24 Oct 2015.

This raw aerial photography covering 23,000 ha of the Desert Road stretch of SH 1 running through the Central Plateau is provided to members of the Desert Rd Invasive Legume Control Group so that they can locate plants and prioritize areas where ground control is required.

Broom produces chemicals that prevent native seedlings establishing and then forms dense thickets able to shade out all other regenerating plants. This can occur from the road edge right to the snow line.

Estimated image resolution = 0.4 m
