[R] barplot - easy for experienced, difficult for me

[happyR]

hey guys,

I wanna make a simple barplot, looking like this excel graph: 
<http://r.789695.n4.nabble.com/file/n4677251/barplot_invertebrates.jpg> 

my data set includes 9 groups of invertebrates (x-axes) and total number
(y-axes) from two different parks (1 and 2).

my data-set looks like that:

I'm a bloody beginner and happy for your help.

ps: if you know what other graph could be interesting to make out of this
very simple data, go ahead and let me know!
