Survey/Project Name: Mistletoe and Brushtail Possum Monitoring (Clare Valley)
Abstract: Some areas of remnant native woodland in the Clare Valley are percieved to be under threat due to mistletoe infestation. This monitoring is looking at the decline of Brushtail possums which are now considered rare in the Mid North due to loss of hollows and tree clearance. The Brushtail possums may have a regulating effect on the Mistletoe population which is one of their favoured foods.

Survey Type: Vegetation and Vertebrates
Study Area Description: *** No study area description recorded
         Vegetation: The four sites of remnant native woodland used in this survey have previously been surveyed by members of the Mistletoe Action Group (MAG) and have been identified as areas under threat by mistletoe infestation. One transect is established at each of the four sites, 1-2 km in length. At 5 points along each transect (0.2 km, 0.4 km, 0.6 km, 0.8 km and 1 km) the closest 20 trees are identified to species, height recorded, presence/absence mistletoe recorded, number of mistletoe counted, whether mistletoe is juvenille/ adult and each tree is assigned an infestation class based on the Native Vegetation Council guidelines. Observations on fire scars, herbivory on mistletoe and number of hollows is also recorded. Density of understorey species are estimated by measuring the distance from each tree to the nearest shrub, then from that shrub to the shrub nearest to the first one, with the restriction that the angle from the tree to the first shrub to the second shrub must be greater than 90 degrees.
         Fauna: The same four sites have been surveyed by DEH staff for the presence of Brushtail possums. The same transects are used as for the mistletoe but where transects are 2 km in length the presence of Brushtail possums are only recorded for the first 1 km of the transect.
         Vegetation: *** No vegetation methodology recorded
         Fauna: *** No vertebrate methodology recorded
