Polygons showing tree cover change as defined by woody vegetation greater than 2 metres in height and with a crown cover (foliar density) greater than 10%. Tree cover is mapped down to a minimum area of quater hectare for change period 1990-1995. Attributes outlining the causes of tree cover change are assigned for areas greater than 1 hectare. This layer was derived from LANDSAT TM digital data.

This layer identifies Forest Cover Changes in Victoria from 1972 to 1987. Forest Cover is defined as woody vegetation greater than 2 metres in height and with crown cover (foliar density) greater than 10%. The smallest unit of forest mapped was fifteen (15) hectares.

A 6-in resolution tree canopy change (2010 - 2017) dataset derived from the 2017 Light Detection and Ranging (LiDAR) data capture. This dataset represents a "top-down" mapping perspective and all tree polygons are classed as: (1) No Change, (2) Gain, (3) Loss. No change indicates that this portion of the canopy has undergone no modifications during the time period. Gain indicates that new tree canopy has appeared during the time period. Loss indicates that this portion of the tree canopy was removed during the time period.

This layer delineates the extent of Forest Cover in Victoria in 1869 based on a historial map prepared by William Slight under the direction of R.Bough-Smyth FGS in 1866 and revised by A.Everett in 1869.

This dataset contains the percentage point change in Melbourne¿s urban vegetation cover between 2014 and 2018, represented by polygons. Each polygon is based on 2016 ABS Mesh Blocks. It's part of a collection of data from Plan Melbourne Action 91 initiative also referred to as Cooling & Greening or Vegetation and Urban heat mapping. https://mapshare.vic.gov.au/coolinggreening/

This dataset is a modified version of TREE100 which has been intersected with the 25 thou mapsheet index to break up the larger polygons.

This dataset describes the boundary of the study area used to analyze regeneration and change in status of native ohia forests in the wet habitat on the eastern side of the island of Hawaii. This area includes forests that were heavily impacted by landscape-level canopy dieback in the 1970s as well as forests that were not affected with tree canopy death or defoliation.
