When is a tree not a tree...?

Dont mean to cast "nasturtions" on your explanation Tony and I am sure this may well be the mechanism for establishment of mistletoe but I have always understood that seeds are a self contained entity. Capable of sustaining initial development ( production of roots and designed with two small leaflets...I forget the scientific term atm ) but crucially able to make available the energy required for growth in first stages.....

The seeds are apparently quite sticky and are wiped by the birds from the beaks ( this requires some persistence ) It is this mechanism that lodges the seeds in place...although as you say, bird crap probably plays its part also....

When in the Australian wilderness parks and such I was aware of a great deal of mistletoe in the euclyp sclerafell in certain regions.....

Aren't most seeds like this?

By design Tom yes, they are indeed....if this is no longer the case we refer to them as being no longer "viable "....My point being that bird crap is not a requirement for germination or establishment....

 

However, some seeds do have the requirement of being passed through the digestive system of a bird / mammal before they become 'viable' - scarification. Therefore bird crap is fairly essential in those circumstances!:D
