Pikudei: Where is my tree?

When I was a boy, the Jewish National Fund had pushkas with pictures trees on them.  The donations were supposed to be going to plant trees in ( the relatively newly founded) State of Israel.  The money would be used to reclaim the desert, drain the swamps ( and eliminate malaria [an actual great success]). 

When a big donor would come, the  JNF would show him the plaque over the grove that his money had planted.  When the next donor came, a plaque with her name would be placed at the entrance to the same grove. 

The accounting principles of the parsha are far more sound. The tally of silver corresponds exactly to the number of donors.  

The mishkan was everybody's tree, all mixed into one glorious structure, plated  onto cedar wood .  The cloud and fire of the Lrd hovered over it and the cloud directed the people in the desert. 

The mishkan was like the JNF trees. The mishkan was an act of preparation for the nationhood that would involve taking possession of the land.  The JNF trees were to prepare the land for habitation. 

I wonder if my tree is a cedar? I hope it is a eucalyptus.
