Mistletoe's are a world-wide group of plants which are found in many different habitats. Most early settlers would have known the European Mistletoe (Viscum album), a commonly seen plant culturally associated with pagan fertility rights.
Australia has 85 species of mistletoe, mostly from the Loranthaceae plant family. There are many different species of mistletoe growing in the Capertee district. Most local mistletoes are found growing on open forest and woodland trees such as Eucalyptus, wattles and She-oaks. While most mistletoes photosynthesise from their own leaves they are usually dependent on the hosts sap for water and nutrients.
Mistletoes are often seen growing on trees near the edge of woodland along roads or near cleared land. A 2004 study by ecologist David M Watson near Albury found that 80% of trees growing along habitat edges carried mistletoe compared with fewer than 5% in the interior.The reason for their preference for habitat edges was, according to Watson, related to increased light, decreased fire frequency, increased run off from roads and decreasing numbers of mistletoe eating animals such as possums and gliders at habitat edges. These environment factors have subsequently led to these plants being abundant on the edges of woodland.
While the presence of mistletoe can have a negative affect on the health of the host tree these plants certainly attract a wide range of animals. Associate Professor Watson found that the presence of mistletoe increased the abundance of bird species by 20% or more when compared to similar bush where the mistletoe had been removed. Watson is of the view that the presence of these well adapted plants is 'one of the key factors allowing our woodland-based animals to survive in what's left of their habitat.'
